Our journey from prototypes to marketable products
The present is about foresight. The future is about hydrogen. This is our conviction, and we follow up our words with deeds. We are working on technologies for generating and using hydrogen. We start at the beginning of the hydrogen value chain: with electrolysis. By the end of the decade, we are planning to invest up to € 500 million in industrializing the Hybrion PEM (proton exchange membrane) electrolysis stack, the centerpiece of hydrogen electrolysis.
Who are we? We’re an interdisciplinary team with expertise and passion. The electrolysis technology and service activities are led by Carola Ruse and Paul Simon. Our headquarter is at Bosch’s Stuttgart-Feuerbach location; our sphere of influence is the entire world. The transformation to a low-carbon society can only succeed if we work together and exchange information with all the players committed to advancing climate protection. With our Hybrion PEM electrolysis stacks, we entered the hydrogen production market in March 2025.
The ramp-up of a hydrogen economy requires clear regulatory boundary conditions and reliable technology. At Bosch, we focus on delivering the technology that industries can depend on.
The Hybrion PEM electrolysis stack has a big advantage in terms of increased efficiency. This results from an optimal usage of renewable energy sources, making electrolysis an attractive solution for hydrogen production.
