Sand Battery Trials Begin In Finland.

According to the BBC, the sand battery represents a simple, cost effective way of storing energy. It uses excess electricity from renewable energy sources to heat the sand, which can stay at around 500º C for months. “We have already learnt that our system has even more potential than we initially calculated. It’s been a positive surprise,” says Ylönen. “Whenever there’s a high surge of available green electricity, we want to be able to get it into the storage really quickly.”
