Brewing beer on a large scale requires large amounts of hot steam for fermentation. Rather than relying on fossil fuels, ...

Researchers from China have proposed to combine solar-air source heat pumps (SASHP) with sand-based thermal floor storage in rural clean heating renovation projects. “In rural areas where economic ...

Batteries are the key to the future of the most abundant sources of renewable energy, solar and wind power for one obvious reason: intermittence. If power generators want to replace fossil fuels ...

The community swimming pool in the Finnish town of Kankaanpää is heated with sand—well, a sand battery, to be more specific. Energy utility Vatajankoski has partnered with Polar Night Energy, a ...

Finnish cleantech startup TheStorage says that its thermal storage technology could reduce industrial energy costs by up to 70% and cut carbon emissions by as much as 90%. The system converts ...

Finland is harnessing the unexpected power of sand to decarbonise industrial heat – a major “blind spot” in global emissions. Industrial heat production is one of the largest and hardest-to-solve ...

Haley Mast is a freelance writer, fact-checker, and small organic farmer in the Columbia River Gorge. She enjoys gardening, reporting on environmental topics, and spending her time outside ...

Wind and solar power are intermittent, generating power when it's available rather than when it's needed, so the green energy transition will require huge amounts of energy storage. This could end up ...

Lithium-ion batteries dominate headlines, but most global energy storage relies on simpler methods. These methods include pumped hydro, compressed air, gravity, and thermal storage using sand or rock.

When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. However, scientists remind us that it is not just a seasonal necessity -- heat is also a valuable ...
