KRAFTBLOCK is an energy storage system that is able to decarbonize industries like steel, glass or ceramics, food, chemicals or paper. It will even help renewables to have their break-through in industrial heating.
The modular and easily scalable system is based on a newly developed storage material that consists of app. 85% upcycled materials. It can store up to 1.2 MWh thermal energy at a temperature level up to 1,300 °C.
Due to its modular character, a single module might also be used as a mobile storage unit, that enables you to charge the storage in one place, transport it by truck or train to another place and utilize the heat at the new location.
We decarbonize by storing and utilizing formerly lost or wasted heat. This means Kraftblock minimizes the usage of fossile fuels, avoids the formation of carbon dioxide and increases the economic value of formerly lost or wasted energy.
