New sand battery can store 100 MWh of thermal energy

Polar Night Energy and the Finnish district heating company Loviisan Lämpö have entered into an agreement to build an industrial-scale Sand Battery in Pornainen for Loviisan Lämpö’s district heating network.
The heating power of the new Sand Battery is 1 MW and it can store up to 100 MWh of thermal energy, making it about ten times larger than the Sand Battery in operation in Kankaanpää since 2022.
The purpose of the Sand Battery is to reduce carbon dioxide emissions of the district heating production in the Pornainen municipality and introduce a new flexible heat production technology. The thermal energy storage medium will be crushed soapstone, a byproduct of Tulikivi's production of heat retaining fireplaces. "Loviisan Lämpö is moving towards more environmentally friendly energy production. With the Sand Battery, we can significantly reduce energy produced by combustion and completely eliminate the use of oil," says Mikko Paajanen, CEO of Loviisan Lämpö in a press statement.
