Kraftblock's mission is to design a storage based sustainable energy system.

Kraftblock has created a special type of granule that can store heat up to 1,300°C. Not only is this efficient form of thermal energy storage, but Kraftblock also has high storage capacity and energy density. The uniform size and modular assembly of the storage medium mean that it can be produced cost-effectively and expanded easily. The components are made of 100% inexhaustible materials and up to 85% of materials used for production were previously recycled.
