| Scope & content | Thermal storage system holds enough energy to power 10,000 homes The world’s largest sand battery has been inaugurated in Finland, capable of storing vast amounts of energy generated from renewable sources like solar and wind. The 13-metre-tall structure, which is situated in the southern municipality of Pornainen, is able to store up to 100 MWh of energy – enough to power roughly 10,000 homes for a day. The thermal storage system, developed by Finnish firm Polar Night Energy, works by heating up low-grade sand with excess electricity produced through renewable energy. |
