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 Matthias Ziebell. 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.
One important key to the future of a hydrogen economy are technologies that can be scaled to large volumes. That’s how the Hybrion PEM electrolysis stack by Bosch contributes to a demand-oriented and clean hydrogen production with highest efficiency.
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.
