Thermochemical (TC) heat storage is an interesting technology for future seasonal storage of solar heat in the built environment. This technology enables high thermal energy storage densities and low energy storage losses. A small-scale laboratory prototype TC storage system has been realized at ECN, applying an open sorption system concept. The packed bed contains 17 dm3 of sorption material and is capable of generating 150W of thermal power. An effective energy storage density of approximately 0.5 GJ/m3 was obtained.
