Important technologies for matching supply and demand

Thermal energy storage is a critical asset for enabling a control system to match supply and demand of heat. Renewable heat can be stored underground via thermoactive foundations or boreholes. Naturally occurring energy can be collected in summer, stored underground and then recycled in winter using seasonal thermal energy storage.

Heat can also be stored in distributed heat storage or in thermochemical materials (TCMs) for later use in periods of high demand.
