“This month, Finland launched the world’s largest sand battery, enabling residents to remove oil from their district heating network and reduce emissions by nearly 70 percent, as reported by Euro News. If it continues to operate as efficiently and affordably as expected, sand batteries could become common worldwide. Developed by Finnish company Polar Night Energy, this battery uses excess clean electricity to heat sand to high temperatures, storing thermal energy that can later be released to heat homes and power local industries. This is not Finland’s first sand battery, but it is significantly larger. The facility in Pornainen is an insulated silo that stands 13 meters tall and 15 meters wide, containing 2,000 tonnes of crushed soapstone. The sand retains heat remarkably well, losing only 10 to 15 percent during storage and recovery, according to The Cool Down.”
