The core of the Kraftblock technology is the innovative storage material which can store temperatures up to 1,300°C. Thanks to an advanced storage system, Kraftblock combines high thermal conductivity with high specific heat capacity. Kraftblock is a long-duration storage and stores energy up to two weeks.
The overall function of the storage system is simple: heat is transferred from the heat transfer medium to the storage material, where it is stored. To access the energy when it is needed, the charging process is reversed: A cold transfer medium flows through the granulate and extracts the thermal energy.
Kraftblock offers complete systems that provide energy in the form of electricity, heat, steam and cooling, all the way from the source to the storage unit to the application. The system solution of Kraftblock enables industrial companies to replace fossil energy with renewable energy and recycle industrial waste heat.
Kraftblock's storage system is compatible with a variety of heat transfer media including air, flue gas, liquid salt and even thermal oil. The high energy density and low cost enable highly efficient solutions for multiple industries.
Kraftblock's storage systems can be easily scaled thanks to the modular design with standardized containers, allowing them to be tailored to any application.
