Vatajankowski is using this stored heat, in conjunction with excess heat from its own data servers, to feed the local district heating system, which uses piped water to transmit heat around the area. Rather than transferring electrons from an electrode or transferring water to a higher reservoir with power pumps, a sand battery relies on resistive heating to boost the airs temperature. Polar Night Energy and Vatajankoski, an energy utility in Western Finland, have built a storage system that can store electricity as heat in the sand. "Weve actually studied this quite far, but theres enough to do on the heat side of things for the moment.

The only reason that it makes any sense or anyone would actually do this is that the high-quality power source is essentially freeit is the excess electricity from solar energy collected in summer. Check out what this means in the video below: On the other hand, sand is durable and inexpensive, and can store a lot of heat without dissipation at a temperature of about 500600 degrees Celsius.
