Optimizing Battery Energy Storage Systems for Renewable Energy Applications

Since renewable energy projects are now emerging worldwide it becomes essential to fine-tune the battery energy storage systems (BESS) for providing stability to the projects. The optimization of battery energy storage systems or BESS is a key strategy to maximize the benefits of renewable power.

Power and Energy Ratings

Sizing BESS power and energy in accordance to requirements – high power for frequency control, high energy for solar smoothing

When the sizes are oversized, the efficiency is slightly reduced and it is also costly, when undersized on the other hand, the functionality is greatly limited. 

Operating Conditions

Temperature control is crucial for enhancing the performance of a battery and reducing the effects that climatic conditions may have on batteries.

Avoid contact with factors that reduce battery life, such as exposure to pollutants and other substances.

Battery Chemistry 

Choose battery chemistry that is appropriate for charge-discharge cycles: lithium-ion for cycling in connection with renewable energy sources

Many batteries have various guidelines for DoD, so to avoid damaging the battery, use chemistry specific DoD.

Control Systems

Install smart inverter systems and the renewable energy project management software for the automated control of the entire system.

It is recommended to set optimal SOC values and charge/ discharge rates to enhance the battery efficiency.

Regular Maintenance

Evaluate capacity, review the hardware, and check its status

Ensure that worn out parts and components are replaced as frequently as is desirable to ensure efficient functionality.

These factors include achieving the right size, designing the system, the right chemical composition, proper controls, and proper maintenance to make battery energy storage systems (BESS) offer the best stability in the renewable energy systems and offer them the value they deserve.

Western Australia state budget commits funding for 2.8GWh battery storage projects

Of a AU$2.8 billion (US$1.87 billion) total package of funding for renewable energy, storage and transmission line upgrades, the vast majority – AU$2.3 billion – will go towards the two large-scale BESS assets. Notably, both will be up to 4-hour duration systems, which marks a big step for the Australian market which has been largely dominated by systems of up to 1-hour duration and only more…

"A 1-megawatt sand battery that can store up to 100 megawatt hours of thermal energy will be 10 times larger than a prototype already in use.

The new sand battery will eliminate the need for oil-based energy consumption for the entire town of town of Pornainen, Finland.

Sand gets charged with clean electricity and stored for use within a local grid.

Finland is doing sand batteries big. Polar Night Energy already showed off an early commercialized version of a sand battery in Kankaanpää in 2022, but a new sand battery 10 times that size is about to fully rid the town of Pornainen, Finland of its need for oil-based energy.

In cooperation with the local Finnish district heating company Loviisan Lämpö, Polar Night Energy will develop a 1-megawatt sand battery capable of storing up to 100 megawatt hours of thermal energy.

“With the sand battery,” Mikko Paajanen, CEO of Loviisan Lämpö, said in a statement, “we can significantly reduce energy produced by combustion and completely eliminate the use of oil.”

Polar Night Energy introduced the first commercial sand battery in 2022, with local energy utility Vatajankoski. “Its main purpose is to work as a high-power and high-capacity reservoir for excess wind and solar energy,” Markku Ylönen, Polar Nigh Energy’s co-founder and CTO, said in a statement at the time. “The energy is stored as heat, which can be used to heat homes, or to provide hot steam and high temperature process heat to industries that are often fossil-fuel dependent.” ...

Sand—a high-density, low-cost material that the construction industry discards [Note: 6/13/24: Turns out that's not true! See note at the bottom for more info.] —is a solid material that can heat to well above the boiling point of water and can store several times the amount of energy of a water tank. While sand doesn’t store electricity, it stores energy in the form of heat. To mine the heat, cool air blows through pipes, heating up as it passes through the unit. It can then be used to convert water into steam or heat water in an air-to-water heat exchanger. The heat can also be converted back to electricity, albeit with electricity losses, through the use of a turbine.

In Pornainen, Paajanen believes that—just by switching to a sand battery—the town can achieve a nearly 70 percent reduction in emissions from the district heating network and keep about 160 tons of carbon dioxide out of the atmosphere annually. In addition to eliminating the usage of oil, they expect to decrease woodchip combustion by about 60 percent.

The sand battery will arrive ready for use, about 42 feet tall and 49 feet wide. The new project’s thermal storage medium is largely comprised of soapstone, a byproduct of Tulikivi’s production of heat-retaining fireplaces. It should take about 13 months to get the new project online, but once it’s up and running, the Pornainen battery will provide thermal energy storage capacity capable of meeting almost one month of summer heat demand and one week of winter heat demand without recharging.

“We want to enable the growth of renewable energy,” Paajanen said. “The sand battery is designed to participate in all Fingrid’s reserve and balancing power markets. It helps to keep the electricity grid balanced as the share of wind and solar energy in the grid increases.”"

Note: I've been keeping an eye on sand batteries for a while, and this is really exciting to see. We need alternatives to lithium batteries ASAP, due to the grave human rights abuses and environmental damage caused by lithium mining, and sand batteries look like a really good solution for grid-scale energy storage.

--

Note 6/13/24: Unfortunately, turns out there are substantial issues with sand batteries as well, due to sand scarcity. More details from a lovely asker here, sources on sand scarcity being a thing at the links: x, x, x, x, x

Jessie Fleming x Reader

Summary: Sometimes you forget Jessie’s an engineer. A very thoughtful, but shy one at that. One who feels more comfortable renovating your apartment than telling you she likes you.

Warnings: No warnings.

A/N: I'm hearing some fluff is in order. Hope you all enjoy!

"Where do you want this?" Jessie asked as she stood holding a large box in the doorway to your new bedroom.  

You looked over your shoulder and pointed to the walk-in closet. "Over there would be great. Thank you." 

"No problem," Jessie replied as she walked over and set the box down. She looked around as she stood. "Are you doing anything with the shelving in here?" 

"Oh yeah," you said as you got up and joined her. "I'm going to move these shelves up and add another set here to create more storage." 

"Smart. That'll be good," Jessie affirmed as she scanned the space.

You tried not to stare, but her profile, curious eyes, and the way her baby hairs stuck to her face after several trips to and from the moving truck made it challenging.   

"Hey, I think that's everything." 

Both you and Jessie turned when Janine's voice filtered in from the bedroom, seeing Kelli standing beside her.  

"Oh amazing. Thank you so much, all of you. I'm sure your coach would have my head if he knew you helped me move, but I'm very grateful. And hey - no injuries! Knock on wood. I guess you all still have to make it home in one piece," you joked.  

"Anytime," Janine said as she crossed the room and gave you a hug. "The new digs look great. Condo ownership looks good on you." 

You laughed. "Thank you. And it's even better when highly trained athletes do all the heavy lifting for you." 

"No unpacking though," Kelli joked. "That's where I draw the line." You held up your hands in mock surrender. 

"I can handle that part. Thank you. Next round of dinner and drinks are on me." 

Once everyone left and you continued the tedious task of unpacking, your phone dinged with a text. You retrieved it to see Jessie's name on the screen. 

"Hey. I hope unpacking is going well. I just wanted to say that if you need any help redoing your shelves I'm happy to swing by. I like projects like that." 

A small smile tugged at the corners of your mouth.  

"Sometimes I forget you're an engineer. You've done so much as is - I already rolled the dice by getting you to help me move furniture and precariously packed boxes. I don’t want to push." 

"I really don't mind! And setting up shelves is a lot less risky than holding the bottom end of the couch on the stairs while Kelli and Janine argue about how to angle it through a doorway." 

You laughed recalling the scene in your mind. She had a point. Plus, spending some time alone, just the two of you, wouldn't be unwanted.  

You'd met through Janine a few months back and had become friends in your own right since then, but it was still the norm that you typically only saw each other with Janine. This could be a nice change of pace. And, you know, if seeing her work in such a capacity would turn out to be eye candy - so be it.  

"Alright. You've convinced me. When are you free? And please, please know that if you change your mind it's really not a problem at all. Please don't feel pressured or obliged." 

"Excellent! Does next Sunday work for you? I'd say Saturday, but we have a game that afternoon." 

"I'm aware lol. I'll be there, after all. Sunday sounds great." 

"Right lol. Okay, Sunday it is! Let me know if you need me to pick anything up prior. I'm happy to." 

"You're too sweet. See you then." 

----- 

"You brought your own drill set?" You asked with an amused smile. The blush on Jessie's face was immediate. 

"Well, I didn't know what you had." Her voice rising in pitch. "And I have a spare battery. There's nothing worse mid-project than running out of a charge." 

"Nothing," you mocked affectionately and she averted her gaze as her cheeks grew redder. You smiled at her and ushered her to the walk-in. "Okay, well, between the two of us I think we're all set. Let's get started." 

It didn't take long for it to become Jessie leading and you helping. Going in, you felt you had a decent grasp of what to do, but as the work progressed, you realized how good it was that Jessie was here because she guided things with confidence and ease that you had to admit you probably wouldn't have had in her absence.  

You were expecting this to be an all day venture, but with Jessie at the helm the work went by quickly and smoothly.  

"Hand me that last shelf, please," she instructed calmly as she double-checked her work. 

You were ready with it and handed it up to her. You watched in what you hoped was subtle appreciation as she set it in place.

She stood perched on the ladder, wearing her black hat and her shirt was tucked in. The tape measure was hooked onto her pocket and she wore a soft look of concentration on her face. When she took the shelf, her biceps popped as she lifted it and set it down on the brackets with ease. The pencil tucked behind her ear was the cherry on top.  

Once she was confident the shelf was secure, she turned to you with a bright smile.  

"All done! What do you think?" 

"It's fantastic," you relayed, forcing yourself to refocus. And it was true. Not only was her workmanship thorough, but she'd tweaked a few things in your plan to optimize the setup even further. "Thank you so much. This is better than what I could've imagined. I owe you big time." 

She shrugged and focused on her feet as she stepped down off the ladder. "No, it's all good. It was fun." 

"Well, I really appreciate it. Truly," you went on, seeking eye contact, but she seemed to readily avoid it as she began cleaning up her tools. Eventually, she looked to you with a small smile. 

"Don't mention it. Thanks for letting me help." 

You rolled your eyes teasingly. "You're funny. Can I at least order us in some dinner and make you a drink or two?" You saw her begin to hesitate, a blush creeping up on her cheeks as she fidgeted. Early on, you would've immediately backed off, fearing you were making her truly uncomfortable, but by this point you knew she was just shy. And a bit skittish. You went on gently. "Consider it a small token of my appreciation." 

She gave you a crooked smile as she distractedly readjusted her hat before seeming to catch herself and clasped both hands in front of her. "Okay, sure. That sounds good." 

You two talked fairly late into the night and you noted how Jessie relaxed into the evening. Conversation was easy and naturally weaved from the light and fun to the more serious and heavy without getting uncomfortable or awkward. The night only came to an end because you had to work in the morning.  

"Thank you again for all of your help," you told her as she stood at your front door, shoes, jacket and backpack on. "Not only does the closet look great, but it was a lot of fun - thanks to you. I can't help but think about projects half that serious that I've done with exes and they've turned into all out brawls. So, thank you." 

Her posture straightened slightly and as she blushed with a nervous laugh. "Well, what can I say. We work well together." If you were right, the flush of her cheeks deepened. She averted her gaze, shuffling her feet a bit before she shoved her hands in her jacket pockets and nodded over your shoulder.  

"You said you were going to change out the lighting fixtures in the living room, right?" She asked. Her smile morphed into a smirk. "I mean, I'm not an electrical engineer, but a couple lighting fixtures is no big deal. I could come over next week and help with those." 

You gave her a smirk of your own, unknowingly looking her up and down.  

"If you'd really like to. I certainly won't stop you." 

The easy confidence she was trying to channel a moment ago flickered before she gave you a nonchalant shrug.  

"Sure. It's not a problem." 

"Alright," you accepted. "I'm looking forward to it. Thanks again, and good night." You leaned forward and pulled her into a short hug - something you hadn't done before - and it seemed to catch her off-guard as she very belatedly put her hands up around you as you were already beginning to pull away, and even then, her movements were stiff and tentative. When you fully broke away her face was beet red.  

"Okay." Her voice was high and tight. She gave you a quick, awkward wave before turning to leave. "Have a good night."  

----- 

The next weekend rolled around and Jessie was yet again up on a ladder in your new apartment. She tilted her head and frowned in concentration as she installed the last set of screws on your new lighting fixture.  

"Okay, go ahead and turn the breaker back on," she told you as she stepped down and walked over to the light switch. You did as you were told. 

"Okay, done." 

The switch went on with a soft click and light filled the room. You watched her before looking up at the newly installed fixture. She smirked.  

"Looks good," she said. “How do you like it?”

“It's brilliant. Thank you again. But what I’m really interested in is this,” you said as you closed the space between you two and grasped her hand, she tensed at the contact, but didn’t pull away. You lifted her hand to see the cut on her knuckle.

“I knew it. Let’s get you cleaned up,” you said and at that she pulled her hand back, hiding it behind her back.

“It’s nothing. I’m fine.”

“I know you are, but still,” you told her gently, noting the embarrassed look on her face. “Indulge me. Let me at least put a bandaid on it.”

She grumbled in contemplation but eventually conceded. You smiled to yourself at how her head jerked away when you glanced up from her hand to catch her staring at you.

When you finished placing the bandaid on her you released her hand and took a step back. You waited to catch her eye and spoke, “Make sure you clean that up more when you get home.”

Her cheeks grew pink and she rolled her eyes. You caught the hint of a smile on her lips though.

“Yes, ma’am.”

Jessie stayed for dinner and a drink once more. Conversation flowed even easier, if that’s possible, than last time. You tried to hide the smile over how pleased you were by this since you and Jessie had been texting all week in between. It would've been understandable if you ran out of things to talk about by this point, but you didn’t - at all.

"I noticed there were a couple of dings in the drywall - probably from when we were moving stuff in. Probably Janine's doing - I'm much more conscientious," Jessie relayed with a facetious eye roll. "I could patch those up for you. I imagine the previous owners left some of the original paint or we could just get it paint matched." 

You smirked at her from across the couch.  

"You know, we could always just hang out - no reno job required. You don’t have to do something every time." 

She blushed and took a sip of her drink.  

"Oh, well, you know. I don’t mind." 

"Well, how about we just hang out next time. If you are desperate to repair the drywall even after that, well, have at 'er. But maybe a work-free, normal hang out would be nice," you told her with a soft laugh. She nodded, blush fading as she returned your smile.  

“Okay, that sounds like a plan." She swirled her drink, looking down at the churning liquid and speaking into it. "You could come over to my place? I could make us dinner. Or whatever." She finally mustered up the courage to look back up at you.

Now it was your turn to blush. You fiddled with your glass and offered her a hint of a smile. "Okay. That sounds nice." 

————

“Whoa. That’s fancy,” Jessie commented as you set down a nice bottle of Chardonnay on her counter.

“Well, it’s my first time over. I had to break out the good stuff for you.”

Jessie grinned and retrieved a couple of glasses for you before setting down two plates of food on the kitchen table.

“This looks amazing,” you told her as you looked at the meal she prepared. “And I can’t help but think this just isn’t fair. You did all this free work for me and now you’ve made me dinner.”

“Was it free?” She squinted at you teasingly. “You had to listen to me babble on about metric versus imperial for a solid 20 minutes there.”

“I didn’t mind. I’d listen to that any day. I like hearing your facts and tidbits and about whatever you're interested in,” you assured her and she tried to conceal her smile. “How’d you become so handy anyway? I mean, I know you have this engineering background now, but still.”

She shrugged. “I liked helping my dad with projects around the house. Helping him build stuff. It was just always fascinating to me to see things come together like that and to know you did it with your own two hands.”

“That’s cute. And very sweet,” you told her as you took a bite. She dismissed your comment with a small wave of her fork.

“It’s not a big deal.”

“Well. I still think it’s cute. And I certainly reaped the rewards. Thank you again - seriously, for all of your help. You didn’t have to help me, and I really appreciate all the work you did.”

She took a sip of wine and peered at you over the glass, taking a moment to contemplate.

“There’s still that matter of the drywall,” she joked.

“You’re still on that, huh?” You said with a laugh. “What are we going to do when there are no projects left to work on?”

A faint blush began to form on Jessie’s face and she shuffled around in her chair a bit before taking a bite of food.

“There are always projects to be done. And if not, well, you’re the one who said we could hang out without a project to work on.”

You propped your elbow on the table and rest your chin in your open palm. “And the offer still stands. Clearly,” you gestured around her apartment. “If you’re interested.” Jessie dropped your gaze and flushed a deeper tone of pink.

“Yeah. I mean, we get along alright.”

You snickered a bit before taking a sip of your drink.

“What resounding affirmation," you said dryly and she shot you a bashful look. You smirked. "I guess it’s settled then.”

You polished off the bottle of wine that evening and your conversation carried you late into the night. You made a point of not checking the time and Jessie made no attempt to either. You had to work in the morning, but you just didn't care. You'd deal with the consequences later.

At some point though, an inevitable yawn escaped Jessie.

“Oh, I should let you get to sleep,” you offered, though not yet moving from your spot on the couch next to her. You were sitting across from one another and you were very aware of how if either of you shifted in a particular way, your legs would brush.

“No, it’s fine,” she dismissed. “I’ll get my second wind here in no time.” You chuckled and finally checked your phone. Your eyes went wide.

“Oh shit,” you laughed. “Well, I’ve worked off of less sleep before.”

“You didn’t tell me you were working,” she frowned at you. “Yeah, some clients are in from out of town. It’s okay, I wanted to hang out with you.” You reluctantly rose from the couch and she followed. “As much as I'm enjoying myself, I should go. I can get about 4 hours of sleep if there are no delays on the train.”

“You are not taking the train,” Jessie told you in the most stern voice you’d ever heard from her. It actually caught you off guard and you ignored the stirring in your chest at her display.

“Fine. An Uber,” you conceded.

“No. I’ll drive you,” she countered.

“Don’t be silly.” You waved her off. “You’re tired too and I’m not making you drive 30 minutes across town and back at this hour.”

“Then…I don't know, just spend the night.” She immediately held up her hands in defense. “Not like that. I just mean…it’s super late, getting home is going to be a pain. I’ll drive you home in the morning whenever you’re ready.”

“Jessie…” It was tempting. The logic wasn’t entirely bulletproof, but reasonable enough.

In the time you took to start contemplating, Jessie had run to the closet and started pulling out spare pillows and blankets. You looked at them when she returned and gave her a discerning look. You didn’t feel uncomfortable, you just didn’t want to intrude.

“I’ll take an Uber in the morning.” You told her and she gave you an easy smile as she began setting up the couch.

“I’ll drive you,” she repeated nonchalantly.

“Oh my god. You’re so stubborn,” you complained half-heartedly.

“Sometimes,” she admitted with a shrug as she went to her room for a few moments and came back out with a set of pyjamas.

“Don’t tell Janine. She’ll never let me hear the end of this,” you warned in mock petulance as you went to take the clothes from her. She pulled her fingers across her lips, feigning a zipping motion.

“She wouldn’t let me hear the end of it either, so I'd say we're now partners in crime,” she laughed, but held the clothes back from you. “These are mine. Yours are on the bed.”

“Huh?” You asked, giving her a blatant look of confusion.

“I’m sleeping out here. You take the bed,” she returned lightly and before you could retort she gently began to corral you towards her bedroom.

“Jessie.” You protested. “Are you nuts? I’m taking the couch.”

“Incorrect,” she refuted before giving you one final, soft push into the room. “I’ll see you in the morning.” She looked up at the ceiling, seeming to calculate something in her head. “6 am?”

“Yeah,” you confirmed, still giving her a lingering look of disapproval. Before you could conjure a retort, she went on.

"This is my house, so what I say goes," she said rather haughtily, coupled with a subtle smirk. She was evidently very pleased with herself and her mannerisms had you too distracted, a small flutter echoing in your chest, so you let it be. You rolled your eyes.

“Fine. Okay. Well, if you change your mind - feel free to kick me out. Of your bedroom or the apartment - either is fine.”

“Now who’s nuts,” she quipped. Her light and easy demeanour wavered slightly as she paused in the doorway and ran a hand through her hair. “Um, well, bathroom’s through there. Help yourself to whatever. Good night.”

You were still in vague disbelief about how the last part of the night had unfolded as you lay in Jessie’s bed, wearing her clothes. Had you previously imagined being in Jessie’s bed? Yes. Did you imagine this? No. Certainly not.

All things considered, you slept pretty well. You didn't expect yourself to, so it was a surprise when your alarm went off. It took you a few moments for your mind to reconcile the unfamiliar surroundings, but you quickly came to. You sat up, the first rays of morning light illuminating the room and you observed them in a more lucid headspace than you had the night before.

The room was neat, organized, minimalistic in a way, but still had plenty of things that made it Jessie. A few framed photos of family and friends, her camera, a few, select books neatly displayed, some cute trinkets from her trips around the globe - no medals on display though. How typical.

A sound from the kitchen pulled you from your observations with a frown. You thought you were hearing things at first until you heard a few more faint sounds.

You quickly got changed and tentatively opened the bedroom door a crack to peer out. Not only was Jessie up already, she was in the middle of making breakfast. You opened the door the rest of the way with a puzzled look on your face. She turned to you with a smile.

"Morning! How did you sleep?"

"How long have you been up?" You asked instead. She glanced at her watch.

"I don't know. 30 minutes maybe? So, how did you sleep?" She repeated her inquiry.

"Shockingly well," you replied with a light laugh as you leaned on the kitchen counter and watched her work. "How about you? Miss I-insist-on-taking-the-couch."

She shot you a smirk over her shoulder as she scrambled the eggs in the frying pan. "I slept perfectly well, thank you," she relayed pointedly. "Coffee?" She asked.

"Please."

"Black, right?"

You smiled at her. "Yes, thank you. Can I do anything to help you?"

"Nope, just about done," she told you as she handed you a travel mug with steaming hot coffee. "For the road," she explained.

You watched Jessie as she turned back to the stove and continued making breakfast. For a split second, you pictured yourself as a couple in this moment. Easy mornings together, sharing breakfast and coffee, talking about your day ahead, kissing each other goodbye and going your separate ways until you came home to one another. You cleared your throat and shook out your head subtly as you came back to reality. You didn't want to get too far ahead of yourself.

You both ate a quick breakfast together, and took your toast and coffee to go. Jessie navigated through traffic on the way to your apartment. You scolded yourself internally for how you found something as simple as Jessie driving, attractive. Okay, maybe you really had it bad for her.

"I have to say, I feel like I'm 18 again or something," you joked. "Getting 4 hours of sleep, going through a whole bunch of hoops just to get to school - or work in this case - on time. It's ridiculous. But it was fun." You took a sip of your coffee. "I bet you were in bed by 10 every night in uni - minus late game nights, if that was a thing. But 8 hours of sleep, very responsible, all your readings and homework done."

Jessie shot you a mild glare.

"I've had some wild nights," she countered, not sounding entirely convincing, or even remotely, really. It endeared her to you more.

"Oh yeah, I bet you were a real bad girl," you teased. Jessie rolled her eyes.

"Oh, and like you were."

You sat primly and gave her a sly smirk. "Wouldn't you like to know."

You bantered back and forth the rest of the drive, and again, it felt like you were already something you were not. You found yourself lamenting your arrival as she pulled up to your building. Pushing aside your disappointment, you instead leaned over the middle console and gave Jessie a fleeting kiss on the cheek. She startled at the touch.

"Thanks for driving me. And for letting me spend the night. And for dinner," you frowned as you added things to the list. "I've gotta start pulling my weight here."

"No," she said in a strained voice, her cheeks flaring up as she glanced at you before her eyes darted away. She laughed nervously and scratched the back of her neck. "Don't mention it."

You gave her forearm a quick squeeze, a blush threatening to form on your own face at how firm the muscles were there, and stepped out of the car. You walked to your door, quickly strategizing if or when to turn back and wave when you heard her call out your name. You turned around with a puzzled look on your face.

"Uh, I could drive you to work? When you're ready?" She offered from the car through the now-open window. Her face burned impossibly brighter red. "It'll be faster than the bus."

You smiled openly at her.

"Oh, you're just spoiling me now." She smiled in return. "Well, who am I to say 'no'?" ------

Hey folks let me anti-doomscroll you for a quick second:

Batteries and Solar have been getting cheap very quickly for a long time now and not only is it not stopping, but even at the rates it's at the economics of energy are shifting rapidly. The costs of decarbonizing all forms of electric power are now more down to infrastructure and planning than bulk cost. Compare and contrast to the turn of the century when Solar was so prohibitively expensive that saying we'd meet any meaningful fraction of our needs with photovoltaics would have gotten you laughed out of the room.

Meanwhile, although there are lots of complicated moving parts and a surprising amount of gross politics attached, gas cars are now less good in most ways than electric. Again, at the turn of the century this would have sounded laughable.

Many industries have specific needs that prevent direct conversion to electric, but hydrocarbon fuels are not intrinsically fossil fuels and can be made as a storage medium for solar. Hydrocarbon fuels made in this way are intrinsically carbon neutral. The technology is relatively young, but from a basic math perspective looks very doable.

Inflation actually has more to do with the above than it does with whatever it is the federal reserve does, and pulling down a supply of energy from the sky that requires less infrastructure to get (which is true because that's why it's cheaper now) directly helps.

The current "business as usual" scenarios with global warming are lower than they used to be, because the solar transition is just sort of happening because of economics without a lot of government help. All of the above lower the amount of friction and pushback we face when trying to get the government to do something.

By the way, the Inflation Reduction Act, passed by Joe Biden a couple years back, is explicitly designed to accelerate these trends.

As disastrous as the current projections for global warming are, it's important to keep two things in perspective: first, that they are exactly that, disasters, not the end-of-the-world kind but more sort of the hurricanes and floods kind, and second, while they certainly will get worse before they get better, they can and will get better. What we do now from a policy perspective has an outsize impact on how much flooding, droughts, and other weather-related costs we will face in the decades to come, but "human civilization ends" is not actually particularly likely. It is much more realistic to say "we could have a huge number of climate-related disasters or a moderately increased number, and every little bit of policy work helps move the needle".

We can and we will solve global warming, the question is not if but when, and how many lives can we save or improve by acting as soon as possible. Imagining this as an almost-certain death sentence for the future of humanity and nature is not merely unrealistic, but wildly counterproductive. It is paralyzing and enervating when what will do the most good is planning, policy, and communication.

Remember, despair is not a tool for positive change. Hope is the real language of revolution.

I added more things to Lotus Tower! Can you spot them all? To be honest, I can't pick anything I'm the most proud of. I'm so pleased to see all of it come together like this. Perhaps my brain will finally let me put the project to rest 😂

Breakdown of all the new fun decorations and modifications below.

You can see the first part of my model build here, or more of my art and my craft projects in my pinned post, where you can also find a link to my INPRNT store and my ko-fi if you would like to support my creative projects in any way 💛

So, the first thing I wanted to do was utillise some spare parts from my Life of Su Dongpo booknook kit to make Li Lianhua a small tea tray:

I cut tiny planks of wood from a strip of basswood to form the sides, but the base and teapot come from the Su Dongpo kit. I was also able to make the goodest girl Hulijing a stand from the same piece that makes the base of the tea tray. Now she can sit in Lotus Tower anywhere she wants to instead of being stuck into the wood outside her kennel!

To hold the tea tray, I also made a table and stool similar to the one in the show, and created some tiny baskets out of beige cross-stitch aida to replicate the many baskets and storage Li Lianhua has hanging from the Tower:

In that same vein, I used thread to make a net for some more storage beneath the stairs:

And used part of a bamboo place-mat and some dried flowers to create a herb drying rack on the upper level.

One of the more complex pieces I created was a second sail to hang under the eaves of the gourd door:

It was difficult trying to get this sail to hold a good final shape as, just as with the other sail in my first build, I had to guess how much material would be needed and how to gather it. But I'm pleased with how it turned out in the end! It, like the herb rack, is hung from the eaves with small pieces of metal wire, bent into hooks and stuck into the reinforced card.

You can also see in the pictures above that I added "rope" and a fake hook to the shelf on the side of the Tower to make it a bit more accurate to the show's design.

(You will also see in the very first picture that I made a set of removable stairs for the porches - unfortunately, I didn't take any pictures of their building process and kept forgetting to move them back into the big picture.)

The biggest addition, though, is of course the lanterns:

I am so proud of these. I made them from paper and basswood, and they are ridiculously tiny (about 1.5cms). I wasn't going to put lights in them to start with, but when I bought the tiny bulbs (I was planning to try and put them inside Lotus Tower at the time) and shone them behind one of the lanterns - it looked so good I knew I just had to try it.

So here's how I pulled it off:

I first carefully slotted the bulbs and their wires through the beams of the sail awning, twisting the red and blue cables around each other to give them more structure and make sure they were hanging at the right length. I made sure the wires both led back to the side of the Tower I was going to store the battery pack on, and fastened them to one of the supports of the awning so that the wires would discretely trail down to the floor of the upper level. (I also painted them at this time.)

As for the battery pack, I stuck a small piece of wood underneath the porch where Hulijing's kennel sits for the battery to sit on. I tidied up the wires as neatly as I could and fastened them to the side of the Tower with a spare U-shaped piece from the Su Dongpo kit, wedged into the window slats of the ground level (making sure there's plenty of slack for me to unfasten it and change the battery without struggle). I then joined the wires as best I could and painted it all a yellow-brown colour.

As you can see, it looks a bit crude, but once the roof is back on over the door, the wires all but disappear!

I am so sooo happy with how it's turned out. Please let me know what you think! Is there anything else you would add? Anything you would do differently?

I think that Raphael could be able to take over the Nine Hells.

“Raphael is biting over more than he can chew with his plans to take over the Nine Hells.”

“If the Crown of Karsus was so powerful why wouldn’t Mephistopheles have already used it?”

*Puts on my tinfoil hat* shhhh, come here…hear me out.

If you’ve read the Annals of Karsus, we know that there are three artifacts that are known as “The Regalia of Karsus”. There is the Crown, the Orb, and the Scepter and they are ‘the physical embodiments of Karsus’s wizardry’. Each of the three artifacts have their own power and purpose (this is directly quoted from the Annals of Karsus):

“The Crown of Karsus: to attract and absorb magical knowledge and give the wearer dominion over himself so that he remains his own entity apart from the Weave.

The Orb of Karsus: a storage device or battery that condenses mystic power, ever-gathering so that it must be syphoned at intervals of its excess.

The Sceptre of Karsus: an instrument of projection, a focusing utensil for the precise wielding of unimaginably vast forces.”

We know where the Crown has been: In Mephistopheles archive and later stolen by the Chosen Three.

The Orb?: Sounds a lot like what Gale deals with, but from what I can read, people disagree about whether that is the Orb of Karsus.

The Scepter of Karsus, though, is heavily hinted at to be owned by Raphael. I don’t have the exact quotes, but if someone does feel free to share them. The archivist says something about a scepter that is like the crown being in the collection and I believe Helsik talks about Raphael collecting Karsite artifacts.

If Raphael DOES own the Scepter of Karsus, it makes even more sense why he is so pissed at papa Meph. He owns an incredibly powerful magical artifact of ‘unimaginably vast forces’, but he isn’t able to actually use it and wield it because Mystra would stop him in a heartbeat. He needs the Crown to separate himself from the Weave to actually use it.

Let’s quickly talk about another Scepter from Netheril: “The Scepter of the Sorcerer Kings”. Its purpose was to strip the power of gods and banishing their influence from Netheril, but the guy (not Karsus, some other really powerful wizard) never completed it because the Netherese gods stopped him. The scepter, however, could not harm deities that had magic within their control (such as Mystra). But we can all agree that this all sounds very similar to the exact same thing that Karsus would attempt years later? The Scepter of Karsus and the rest of the Regalia of Karsus was even more powerful than The Scepter of the Sorcerer Kings since it could not only steal the power of Mystryl but also transfer it to the wielder.

Let’s go back to the Hells. Mephistopheles keeps the Crown in his vault and doesn’t use it for a millennium. Why? We have established that the Crown absorbs and attracts magical knowledge, and it also separates the wielder from the Weave. The Crown in itself seems powerful, but as many have also said about Raphael, it hardly seems enough to take down Asmodeus in itself.

What if…*adjusts my tinfoil hat* What if the Netherese truly learned nothing and history repeats itself as always, and it is in fact these mentioned ‘unimaginably vast forces’ of the Scepter that is the key to overthrow gods and steal their powers, and not the only Crown. The Crown simply assures that the wearer’s magic is out of reach from Mystra so they can do whatever they want, and it grants knowledge. Meaning, if Raphael has at least both the Scepter and the Crown, he could steal Asmodeus’s powers and go through with what his father could not achieve because his mischievous little son has been holding onto Scepter that is necessary to even wield and project those powers. He would become be the ruler of the Nine and gods know what else. It's not entirely out of the question that he might even have the Orb as well, seeing as we aren't really sure if Gale's Orb is the Orb.

Again, the Crown absorbs and attracts magical knowledge and it’s the key too using all of this naughty magic that Mystra doesn’t want you to mess with, but it does not seem like it actually gives you a whole lot of powers. It essentially just makes you know about it. What if the truly nasty stuff lies in the Scepter? It seems at the very least that the Scepter is necessary to truly harness and project the powers of the rest of the Regalia with any sort of precision.

(If you have any additions or corrections to my insane ramblings, feel absolutely free to add them and I’d love to read them)

Things Biden and the Democrats did, this week #12

March 29-April 5 2024

President Biden united with Senator Bernie Sanders at the White House to review Democratic efforts to bring down drug prices. President Biden touted his Administration’s capping the price of insulin for seniors at $35 a month and capping the price of  prescription drugs for seniors at $2,000 a year. Biden hopes to expand both to all Americans through legislation next year with a Democratic congress. The President also praised Senator Sanders' efforts as chair of the Senate Health Committee which has lead to major drug manufacturers capping the price of inhalers at $35 a month. “Bernie, you and I have been fighting this for 25 years,” Biden said “Finally, finally we beat Big Pharma. Finally.”

The White House gave an update on its actions around the Francis Scott Key Bridge disaster. The federal government working with state and local governments hope to have enough of the remains of the bridge cleared to partially reopen the Port of Baltimore by the end of the month and have the port working normally by May. The Administration has already released $60 million in emergency money toward rebuilding and promises the federal government will cover the cost. The Department of Labor has released $3.5 million for Dislocated Worker Grants and plans up to $25 million to cover lost wages. The Small Business Administration is offering $2 million in emergency loans to affected small businesses. The Administration is working with business and labor unions to keep workers at work and cover lost wages.

Vice-President Harris and EPA Administrator Michael Regan announced $20 billion to help finance tens of thousands of climate and clean energy projects across the country. The kinds of projects that will be financed through this project include distributed clean power generation and storage, net-zero retrofits of homes and small businesses, and zero-emission transportation. 70% of the funds, $14 billion, will be invested in low-income and disadvantaged communities. The project is part of a public private partnership so for every 1 dollar of federal money, private companies have promised 7 dollars of investment, bring the total to $150 billion for ongoing financing of climate and clean energy projects for years to come.

The Department of Transportation announced $20.5 billion in investments in public transportation. This represents the largest single investment in public transit by the federal government in history. The money will go to improving and expanding subways, light rail, buses, and ferry systems across America. The DoT hopes to use the funds to in particular expand and improve options for public transport for people with disabilities and seniors.

The Departments of Energy and The Treasury announced $4 billion in tax credits for businesses investing in clean energy, critical materials recycling, and Industrial decarbonization. The credits till go toward 100 projects across 35 states. 67% of the credits ($2.7 billion) will go to clean energy, wind, solar, nuclear, clean hydrogen, as well as updates to grids, better batter storage, and investments in electric vehicles. 20% ($800 million) will go to to recycling things like lithium-ion batteries, and 13% ($500 million) to decarbonization in industries like automotive manufacturing, and iron and steel.

The Department of Agriculture announced $1.5 Billion in investments in climate-smart agriculture. USDA plans to support over 180,000 farms representing 225 million acres in the next 5 years move toward more climate friendly agriculture. 40% of the project is reserved for disadvantaged communities, in line with the Biden Administrations standard for climate investment. $100 million has been reserved for projects in Tribal Communities.

The Department of the Interior approved the New England Wind offshore wind project. To be located off Martha’s Vineyard the New England project represents the 8th such off shore wind project approved by the Biden administration. Taken together these projects will generate 10 gigawatts of totally clean energy that can power 4 million homes. The Administration's climate goals call for 30 gigawatts of off shore wind power by 2030. The New England Wind project itself is expected to generate 2,600 megawatts of electricity, enough to power more than 900,000 homes in the New England area.

The Department of the Interior announced $320 Million for tribal water infrastructure. Interior also announced $244 million to deal with legacy pollution from mining in the State of Pennsylvania, as well as $25 million to protect wetlands in Arizona and $19 million to put solar panels over irrigation canals in California, Oregon and Utah. While the Department of Energy announced $27 million for 40 projects by state, local and tribal governments to combat climate change

China’s state-owned power generation enterprise Datang Group said on June 30 that it had connected to the grid a 50 MW/100 MWh project in Qianjiang, Hubei Province, making it the world’s largest operating sodium-ion battery energy storage system. The project represents the first phase of the Datang Hubei Sodium Ion New Energy Storage Power Station, which consists of 42 battery energy storage containers and 21 sets of boost converters. It uses 185 ampere-hour large-capacity sodium-ion batteries supplied by China’s HiNa Battery Technology and is equipped with a 110 kV transformer station. Previously, the largest operational sodium-ion system was China Southern Power Grid’s Fulin 10 MWh BESS project, located in Nanning, southwestern China. The power station, which represents the first phase of a 100 MWh project, also features HiNa Battery’s cells.

The 100,000 kWh project in the Hubei province is capable of storing enough electricity to power 12,000 homes on a single charge.[...]

Sodium-ion batteries offer a number of benefits compared to conventional lithium-ion batteries, as they are both cheaper and safer than the batteries found in smartphones and electric cars.[...]

The sodium (Na) required to build them is also 500 times more abundant than lithium. while also holding the potential for greater charge and efficiency than Li-ion batteries.[...]

“Sodium-ion batteries have excellent safety and low-temperature operating performance,” said Cui Yongle, a project manager at Datang Hubei Sodium Ion Energy Storage.

“They can still guarantee 85 per cent charge and discharge efficiency at minus 20 degrees Celsius, which is unmatched by other batteries. They can also guarantee 1,500 charge and discharge cycles at a high temperature of 60 degrees Celsius. Their puncture resistance and impact resistance are much better than that of ordinary batteries.”

An international team of scientists, including two researchers who now work in the Center for Advanced Sensor Technology (CAST) at UMBC, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors. The research was published recently in the journal Nature Nanotechnology. Sanjeev Kumar Ujjain, from CAST, was a lead researcher on the work. He started the project while at Shinshu University, in Nagano, Japan, and continued after arriving at UMBC in 2022. Preety Ahuja, from CAST, also contributed to the material characterization aspects of the research.

What is going on with this 2010 earth ship in Montrose, CO? Usually, I like earth ships, but this is madness. 2bds, 2ba, asking $825K.

It's been 24 yrs., and it's still not finished. The buyer has to finish it. This is ugly. Look at the tire walls.

It's interesting for us, from an architectural standpoint, to see how an earth ship is made. So this is that garden area they always have at the entrance.

Bathroom?

Look at this. I first thought that these were clothes hanging. The tires are vertical and some are clearly flat.

On this wall they're horizontal. So, you put the adobe on these? So, you frame them and put up wallboard?

What a project. How can you figure out how to finish what someone else started?

Don't know what this is.

So, these batteries have been here since 2010.

The solar panel. Surprised there's just one.

39.90 acres of nice trees, but they cleared out the land around the house too much. They didn't leave any trees.

The earth ship looks big, and it looks like there's a house on the property, plus a shed and so many outbuildings, plus a trailer. The description says: "These can serve as storage, workshops, artist studios, or whatever else your heart desires."

African poverty is partly a consequence of energy poverty. In every other continent the vast majority of people have access to electricity. In Africa 600m people, 43% of the total, cannot readily light their homes or charge their phones. And those who nominally have grid electricity find it as reliable as a Scottish summer. More than three-quarters of African firms experience outages; two-fifths say electricity is the main constraint on their business.

If other sub-Saharan African countries had enjoyed power as reliable as South Africa’s from 1995 to 2007, then the continent’s rate of real GDP growth per person would have been two percentage points higher, more than doubling the actual rate, according to one academic paper. Since then South Africa has also had erratic electricity. So-called “load-shedding” is probably the main reason why the economy has shrunk in four of the past eight quarters.

Solar power is increasingly seen as the solution. Last year Africa installed a record amount of photovoltaic (PV) capacity (though this still made up just 1% of the total added worldwide), notes the African Solar Industry Association (AFSIA), a trade group. Globally most solar PV is built by utilities, but in Africa 65% of new capacity over the past two years has come from large firms contracting directly with developers. These deals are part of a decentralised revolution that could be of huge benefit to African economies.

Ground zero for the revolution is South Africa. Last year saw a record number of blackouts imposed by Eskom, the state-run utility, whose dysfunctional coal-fired power stations regularly break down or operate at far below capacity. Fortunately, as load-shedding was peaking, the costs of solar systems were plummeting.

Between 2019 and 2023 the cost of panels fell by 15%, having already declined by almost 90% in the 2010s. Meanwhile battery storage systems now cost about half as much as five years ago. Industrial users pay 20-40% less per unit when buying electricity from private project developers than on the cheapest Eskom tariff.

In the past two calendar years the amount of solar capacity in South Africa rose from 2.8GW to 7.8GW, notes AFSIA, excluding that installed on the roofs of suburban homes. All together South Africa’s solar capacity could now be almost a fifth of that of Eskom’s coal-fired power stations (albeit those still have a higher “capacity factor”, or ability to produce electricity around the clock). The growth of solar is a key reason why there has been less load-shedding in 2024...

Over the past decade the number of startups providing “distributed renewable energy” (DRE) has grown at a clip. Industry estimates suggest that more than 400m Africans get electricity from solar home systems and that more than ten times as many “mini-grids”, most of which use solar, were built in 2016-20 than in the preceding five years. In Kenya DRE firms employ more than six times as many people as the largest utility. In Nigeria they have created almost as many jobs as the oil and gas industry.

“The future is an extremely distributed system to an extent that people haven’t fully grasped,” argues Matthew Tilleard of CrossBoundary Group, a firm whose customers range from large businesses to hitherto unconnected consumers. “It’s going to happen here in Africa first and most consequentially.”

Ignite, which operates in nine African countries, has products that include a basic panel that powers three light bulbs and a phone charger, as well as solar-powered irrigation pumps, stoves and internet routers, and industrial systems. Customers use mobile money to “unlock” a pay-as-you-go meter.

Yariv Cohen, Ignite’s CEO, reckons that the typical $3 per month spent by consumers is less than what they previously paid for kerosene and at phone-charging kiosks. He describes how farmers are more productive because they do not have to get home before dark and children are getting better test scores because they study under bulbs. One family in Rwanda used to keep their two cows in their house because they feared rustlers might come in the dark; now the cattle snooze al fresco under an outside lamp and the family gets more sleep.

...That is one eye-catching aspect of Africa’s solar revolution. But most of the continent is undergoing a more subtle—and significant—experiment in decentralised, commercially driven solar power. It is a trend that could both transform African economies and offer lessons to the rest of the world."
