Finns open first commercial sand battery Better than making sandcastles Polar Night Energy says it's just opened its first commercial sand battery at the premises of "new energy" company Vatajankoski, a few hours out of Helsinki. For those who don’t know, a sand battery is a thermal energy storage system, built around a big, insulated steel tank -- around 4 meters (13.1 ft) wide and 7 meters (23 ft) high – and full of sand. When this sand is heated up, using a simple heat exchanger buried in the middle of it, it can storing an impressive 8 megawatt-hours of energy, at a nominal power rating of 100 kW, with the sand heated to somewhere around 500-600 degrees Celsius (932-1112F). https://fudzilla.com/news/55108-finn...l-sand-battery |
