Ten Energy Storage Methods
7) Pumped Heat Electrical Storage. Pumped Heat Electrical Storage stockpiles electricity by using it to drive a heat pump that moves heat from a "cold store" to a hot store," comparable to the way a refrigerator moves heat from its interior. To recuperate the energy, the heat pump is flipped, taking from the hot store and putting it in the ...
