Koolen Industries’ 3€ Million Investment in Kraftblock


Luther Rechtsanwaltsgesellschaft mbH advised Koolen Industries.

Dutch clean energy conglomerate Koolen Industries has invested €3 million in Kraftblock, a German firm that uses nanotechnology to develop new ways to store and transport energy as heat.

Kraftblock’s thermal energy storage system is used to capture excess heat, which is an inevitable by-product of industrial operations, and reuse it as energy for production.

Kraftblock (formerly Nebuma GmbH) is a green tech startup founded in Saarbrücken in 2014 that manufactures high-temperature storage systems. The patented, nanotechnology-based storage granulate can effectively store temperatures of up to 1,300 degrees, which leads to significantly higher efficiency than in conventional thermal storage systems. By offering the storage system in modular containers, mobile, transportable as well as stationary applications are possible. The company was founded by Dr. Martin Schichtel and Dr. Susanne König.

Koolen Industries is a group of companies that cooperate to offer complete, integrated clean energy solutions to companies and consumers. Whether it is about solar energy, lithium batteries, power to gas solutions, charging infrastructure or a combination thereof; Koolen Industries can transfer the wish of customers into reality. The mission of Koolen Industries is to enable everyone to contribute to and participate in the energy transition. Generating clean energy from wind and the sun, and developing solutions that store, transport and deliver this energy, we provide consumers and industry with an autonomous life that is independent of the grid.
