Net-Zero Heat System
Stores renewable electricity as heat for industrial processes
The Net-Zero Heat System from Kraftblock is a high-temperature thermal energy storage system designed to replace fossil fuels used for process heat generation in industries. It operates by converting renewable electricity from the grid or a plant's own sources into heat with 98% efficiency. The heat can then be stored in compact Kraftblock containers for minutes up to two weeks at temperatures ranging from 50°C to 1,300°C. When needed, the stored heat is discharged and adapted without energy loss to supply the required temperature for industrial processes.
The system allows the utilization of cheap or surplus renewable electricity when available, enabling a shift in energy availability to provide 24/7 operation. The thermal energy storage acts as a buffer, decoupling the electricity supply from the heat demand. This approach aims to decarbonize high-temperature industrial processes, such as those found in the steel, glass, ceramic, and chemical industries, by transitioning them to renewable energy sources. The modular and adaptable design of the Net-Zero Heat System allows for customized layouts tailored to specific process and facility requirements.
