Europe’s leading impact ventures in water, energy & food

Kraftblock is a high-temperature (up to 1,300°C) energy storage system designed to decarbonize the industry. Their solution can store approximately 3 times more energy than current industry solutions, and charges twice as fast. The process produces only 180 kg/MWh CO₂ which is almost five times more efficient than alternatives.

Innovative energy storage

The world’s shift to renewable energy needs a solution to one central challenge: how to store excess solar and wind power for later use. Meanwhile, energy-intensive industries have a challenge of their own: what to do with all of the excess heat they generate. Kraftblock CEO Martin Schichtel, a chemist by training, believes his German-based company has the answer – a thermal-based storage system.
