APEX Group

The APEX Group is one of the pioneers of the green energy transition. The company is headquartered in Rostock / Laage. It enables customers to convert their own and conventional energy supply to green hydrogen in a decentralized manner. This includes project development, engineering, procurement and construction as well as management and maintenance. In recent years, APEX has developed its own hydrogen pressure storage system together with the Fraunhofer Institute in order to guarantee a reliable supply. Together with established research institutions (especially the Leibniz Institute for Catalysis), the Rostock-based company is currently developing the next major innovation: the chemical storage of hydrogen. In March 2021, the company commissioned what was then the largest network-connected hydrogen plant in Europe. The APEX Group will supply their company location and, in the future, the adjacent industrial park in a completely CO₂-neutral manner.
