Thermal energy storage - a key component of the future energy system

The energy transition demands not only the expansion and integration of renewable energy sources, but also smart solutions for the storage and distribution of electricity and heat. Heat storage systems offer an efficient means of temporarily storing heat energy and providing it in line with demand. They play a key role in decarbonising the heating sector and in stabilising the renewable energy system of the future.
