"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

I really hope they can work the bugs out of this solution, because if it's done right, it'll really be a win-win situation. Less evaporation of water, and solar power being generated every day? Yes, please. We are smart, resourceful beings, and this is far from the most difficult problem we've had to address.

This is also a great example of how we can go back and fix mistakes of the past. We very, very rarely ever come up with technological solutions that take long-term effects on the environment into consideration, and so the way many things are designed often leads to some sort of damage, whether through manufacture, use, disposal, or all of the above. Retrofitting canals (which have been used in agriculture for thousands of years) will have benefits not only in the ways mentioned above, but also gets people thinking more about the impacts we make.

I'm hoping that this will lead to more new technology being developed in ways that already anticipate and account for negative impacts so that they avoid them in the first place, rather than having to engineer new solution many years down the line.

Vast arrays of solar panels floating on calm seas near the Equator could provide effectively unlimited solar energy to densely populated countries in Southeast Asia and West Africa. Our new research shows offshore solar in Indonesia alone could generate about 35,000 terawatt-hours (TWh) of solar energy a year, which is similar to current global electricity production (30,000TWh per year). And while most of the world's oceans experience storms, some regions at the Equator are relatively still and peaceful. So relatively inexpensive engineering structures could suffice to protect offshore floating solar panels. Our high-resolution global heat maps show the Indonesian archipelago and equatorial West Africa near Nigeria have the greatest potential for offshore floating solar arrays.

“At its fastest rate of deployment, mining quantities for low-carbon energy will be 500 to 1000 times less than current fossil fuel production.

But even this underestimates the differences in these quantities: the numbers for fossil fuels are the amount we need every year because they’re the “running” costs.

The minerals for low-carbon energy are like capital costs. The running costs after these technologies have been deployed are much less.”

On This Day In History

April 25th, 1954: Bell Telephone Laboratories demonstrates the first practical solar cell.

[reasonsforhope]

Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous the risk of waterborne diseases like cholera.

Via tests in rural communities, they showed that the process is more than 20% cheaper than traditional methods and can be deployed in rural locations around the globe.

Building on existing processes that convert saline groundwater to freshwater, the researchers from King’s College London, in collaboration with MIT and the Helmholtz Institute for Renewable Energy Systems, created a new system that produced consistent levels of water using solar power, and reported it in a paper published recently in Nature Water.

It works through a process called electrodialysis which separates the salt using a set of specialized membranes that channel salt ions into a stream of brine, leaving the water fresh and drinkable. By flexibly adjusting the voltage and the rate at which salt water flowed through the system, the researchers developed a system that adjusts to variable sunshine while not compromising on the amount of fresh drinking water produced.

Using data first gathered in the village of Chelleru near Hyderabad in India, and then recreating these conditions of the village in New Mexico, the team successfully converted up to 10 cubic meters, or several bathtubs worth of fresh drinking water. This was enough for 3,000 people a day with the process continuing to run regardless of variable solar power caused by cloud coverage and rain.

[Note: Not sure what metric they're using to calculate daily water needs here. Presumably this is drinking water only.]

Dr. Wei He from the Department of Engineering at King’s College London believes the new technology could bring massive benefits to rural communities, not only increasing the supply of drinking water but also bringing health benefits.

“By offering a cheap, eco-friendly alternative that can be operated off the grid, our technology enables communities to tap into alternative water sources (such as deep aquifers or saline water) to address water scarcity and contamination in traditional water supplies,” said He.

“This technology can expand water sources available to communities beyond traditional ones and by providing water from uncontaminated saline sources, may help combat water scarcity or unexpected emergencies when conventional water supplies are disrupted, for example like the recent cholera outbreaks in Zambia.”

In the global rural population, 1.6 billion people face water scarcity, many of whom are reliant on stressed reserves of groundwater lying beneath the Earth’s surface.

However, worldwide 56% of groundwater is saline and unsuitable for consumption. This issue is particularly prevalent in India, where 60% of the land harbors undrinkable saline water. Consequently, there is a pressing need for efficient desalination methods to create fresh drinking water cheaply, and at scale.

Traditional desalination technology has relied either on costly batteries in off-grid systems or a grid system to supply the energy necessary to remove salt from the water. In developing countries’ rural areas, however, grid infrastructure can be unreliable and is largely reliant on fossil fuels...

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

The system also has the potential to be used outside of developing areas, particularly in agriculture where climate change is leading to unstable reserves of fresh water for irrigation.

The team plans to scale up the availability of the technology across India through collaboration with local partners. Beyond this, a team from MIT also plans to create a start-up to commercialize and fund the technology.

“While the US and UK have more stable, diversified grids than most countries, they still rely on fossil fuels. By removing fossil fuels from the equation for energy-hungry sectors like agriculture, we can help accelerate the transition to Net Zero,” He said.

Google strikes a deal with a nuclear startup to power its AI data centers

🔹 Google is turning to nuclear energy to help power its AI drive. On Monday, the company said it will partner with the startup Kairos Power to build seven small nuclear reactors in the US. The deal targets adding 500 megawatts of nuclear power from the small modular reactors (SMRs) by the decade’s end. The first is expected to be up and running by 2030, with the remainder arriving through 2035.

🔹 It’s the first-ever corporate deal to buy nuclear power from SMRs. Small modular reactors are smaller than existing reactors. Their components are built inside a factory rather than on-site, which can help lower construction costs compared to full-scale plants. Kairos will need the US Nuclear Regulatory Commission to approve design and construction permits for the plans. The startup has already received approval for a demonstration reactor in Tennessee, with an online date targeted for 2027.

🔹 The company already builds test units (without nuclear-fuel components) at a development facility in Albuquerque, NM, where it assesses components, systems and its supply chain. The companies didn’t announce the financial details of the arrangement. Google says the deal’s structure will help to keep costs down and get the energy online sooner. “By procuring electricity from multiple reactors — what experts call an ‘orderbook’ of reactors — we will help accelerate the repeated reactor deployments that are needed to lower costs and bring Kairos Power’s technology to market more quickly,” Michael Terrell, Google’s senior director for energy and climate, wrote in a blog post. “This is an important part of our approach to scale the benefits of advanced technologies to more people and communities, and builds on our previous efforts.”

🔹 The AI boom - and the enormous amount of data center power it requires - has led to several deals between Big Tech companies and the nuclear industry. In September, Microsoft forged an agreement with Constellation Energy to bring a unit of the Three Mile Island plant in Pennsylvania back online. In March, Amazon bought a nuclear-powered data center from Talen Energy.
