A consortium linked to the Karlsruhe Institute of Technology (KIT) has built a plant at the Mannheim wastewater treatment plant that cleans generated biogas and uses the resulting CO2 to produce climate-neutral marine fuel using green hydrogen. The process could help decarbonise the shipping sector, which is currently responsible for around three percent of global greenhouse gas emissions.

The demonstration plant uses a patented process to convert biogas produced during wastewater treatment into climate-neutral methanol. The biogas is first purified and the separated CO₂ can then be used with renewably-produced hydrogen to make methanol – a raw material that can be used as marine fuel or in the chemical industry. Methanol does release the CO2 back into the atmosphere when burned. However, because the carbon comes from the treatment plant and not from additional fossil sources, it is considered climate neutral.

There are some 80,000 wastewater treatment plants in Europe that offer considerable potential for the new process, wrote KIT. "To achieve our climate protection goals, we must keep all technological options open," said Volker Wissing, federal minister for digital affairs and transport. “In addition to electrification and hydrogen-based propulsion, we need climate-friendly fuels, especially in maritime shipping." Stressing that the sector represented a future growth market, Wissing said Germany should play a pioneering role in research and development. "It's also about making our country independent of energy imports."

Vidal Vazquez, co-founder of climate tech start-up ICODOS, a spin-off from the KIT, added, "In Germany alone, wastewater treatment plants could produce several million tonnes of sustainable methanol annually." The project shows that "wastewater treatment plants can serve as the heart of sustainable fuel production – a potential that has so far remained untapped," Vazquez said. ICODOS is currently in discussions with other wastewater treatment plants to set up other production facilities.

Renewables-based synthetic fuels could be necessary to decarbonise certain sectors such as shipping, where alternatives are not available today, or extremely costly. However, producing the rare fuels is energy-intensive and expensive and they should only be used where the direct use of electricity is not an option.

Self-sufficient organic Finnish farm grows its own fuel and a greener future

An award-winning farm has teamed up with Helsinki University to create a symbiotic food production system that is self-sufficient in energy and nutrients. It’s a trailblazer in sustainable agriculture.

Organic Knehtilä Farm provides its own nutrients and energy, thanks to careful long-term planning and a small onsite biogas plant operated by energy utility Nivos.

The biogas powers his tractor, pickup truck and cars, and is available to others at a commercial filling station on the edge of the farm, although vehicles that can use biogas are still relatively rare. It offers a valuable alternative to meet the growing need for affordable, clean domestic energy.

Demand for organic food continues to grow. “The price gap between organic and standard production is narrowing, partly because we don’t need fertiliser. Our farm has its own product line of oat and buckwheat products, which are produced here using a proven cultivation method known as agroecological symbiosis, where nutrients and energy are efficiently recycled.”

The sprawling 380-hectare farm’s carefully balanced circular economy has developed over a decade and a half, earning a WWF award in 2015 as a model of nature-friendly agriculture. In 2021, the Finnish Organic Association chose Knehtilä for the honour of Organic Business of the Year.

“Biogas production can convert farms from being energy consumers to energy producers, and play an important role in the transition away from fossil fuels. When it’s done in a smart way, it’s also possible to increase biodiversity in farming systems.”

Knehtilä forms part of the Global Network of Lighthouse Farms, a project led by Wageningen University in the Netherlands, involving commercially viable farms that offer “radical solutions to address sustainability challenges.” International visitors frequently come to Knehtilä to learn about unique system.

The rich, vibrant cycle of life at Knehtilä is visible in not only the lush fields, but also in the insects and frogs that frequent them, and in a few animals such as horses, sheep, goats, chickens and rabbits. The farm is also a lively event venue; a high-ceilinged, 80-year-old barn has been converted to a space for up to 100 people for weddings, theatre performances and concerts.
