Startup is building a giant sand battery in Finland

Posted by in categories: climatology, futurism

The big picture: Sand batteries might not be as efficient for generating electricity as they are for heating, but they could still have a huge impact on climate emissions — about 9% of the heat needed for buildings and industry comes from district heating systems, and 90% of those rely on fossil fuels.

We could then supplement the sand batteries with another alternative form of storage, such as flow batteries, to generate electricity from renewables year-round — completing the transition to a clean energy future.
