Kraftblock is a cleantech company that develops high-performance thermal storage-systems to decarbonise industry and to store and use excess energy from renewable sources. The modular, container-based high-temperature systems can be used either as mobile energy storage, or they can be staged as large-scale stationary storage of energy. The outstanding performance is based on the proprietary storage material that can absorb up to 1,300°C, store up to 1.2MWh per m3 and perform more than 15,000 cycles without any performance losses.
