Saving heat until you need it | MIT Energy Initiative
A new concept for thermal energy storage You can charge a battery, and it''ll store the electricity until you want to use it, say, in your cell phone or electric car. But people have to heat up their solar cooker when the sun''s out, and by the time they want to make dinner, it may well have given off all its stored heat to the cool evening air.
Thermal energy storage
Thermal energy storage technologies allow us to temporarily reserve energy produced in the form of heat or cold for use at a different time. Take for example modern solar thermal power plants, which produce all of their energy when the sun is shining during the day.
