Kraftblock is a German energy technology company that develops and manufactures high-temperature thermal energy storage systems for industrial applications. Their core product is a thermal battery capable of storing heat at temperatures ranging from 50°C to 1,300°C, enabling heavy industries to integrate renewable electricity into their process heat supply. By storing energy during periods of low-cost electricity and releasing it on demand, Kraftblock helps industries decarbonize their operations while achieving significant cost savings compared to direct electrification. The company's mission centers on accelerating the transition of energy-intensive industries to green, carbon-free process heat. Kraftblock serves sectors including steel and metals, glass and ceramics, pulp and paper, food and beverages, chemicals, oil and gas, and energy utilities. Their systems support multiple applications such as net-zero heat generation, waste heat recovery, concentrated solar power optimization, and scalable power generation. What distinguishes Kraftblock is its use of upcycled materials without rare earths, making its storage solution both sustainable and cost-effective at scale. The company's modular and flexible approach allows it to adapt to a wide variety of industrial energy situations, supplying steam, hot air, thermal oil, or hot water based on customer needs. Kraftblock has earned the trust of major energy companies, including Eneco, and positions itself as a resilient, long-duration thermal storage solution for industrial decarbonization.
