The world's largest sand battery just went live in Finland | AI News Digest
Finland has launched the world's largest sand battery in Pornainen, designed to replace an old woodchip power plant and significantly reduce carbon emissions by up to 70%. Developed by Polar Night Energy, this innovative thermal energy storage system stands 42 ft tall and can store up to 100 MWh of energy. It utilizes excess renewable energy to heat sand, which retains heat for long periods, providing a sustainable heating solution for the town. The battery has already exceeded efficiency targets since its operation began in June. This project is expected to play a crucial role in achieving carbon neutrality for Pornainen and may inspire similar initiatives elsewhere.
