Hydrogen, Bosch inaugurates 2.5 MW electrolyzer at the Group’s Bamberg plant
At the heart of the electrolyzer, which was built by FEST, a company based in Goslar, Germany, are two Bosch Hybrion electrolysis stacks manufactured in Bamberg. Each of these stacks with a rated power of 1.25 megawatts produces around 23 kilograms of hydrogen per hour from water and electricity. At full load, the electrolyzer can produce more than 1 metric ton of hydrogen daily. That’s enough fuel for an electric 40-ton truck fitted with a Bosch fuel-cell power module (FCPM) to travel up to 14,000 kilometers.
After launching Hybrion PEM electrolysis stacks back in March, Bosch has now put two of them into operation in an electrolyzer at its Bamberg site. This 2.5 megawatts system converts water into hydrogen and oxygen using renewable electricity, and meets the EU’s requirements for renewable hydrogen.

Bosch to put a lot of efforts in electrolyzer development
“Bosch can do hydrogen, and at scale,” said Thomas Pauer, the president of the Power Solutions division. “We got involved in the area at an early stage, made upfront investments, and are now offering market-ready technical solutions. That includes our fuel-cell power module. The fact that it was nominated for the German Future Prize proves that this Bosch technology is at the cutting edge. And that applies both to the fuel cells and to the electrolysis”.
Bamberg also has a second test station for the Hybrion PEM electrolysis stacks manufactured at the plant there. Before delivering stacks to customers, this is where Bosch ensures that they reliably achieve their performance and efficiency under real operating conditions. Bosch has already reached its first milestones in electrolysis technology in 2025. Following the market launch in the spring, deliveries have begun to various customers and partners, including companies such as IMI, Kyros Hydrogen Solutions, Neumann & Esser, Pietro Fiorentini, and the latter’s subsidiary Hyter.
“For Bosch, hydrogen continues to be a strategically important business. The official start of operations for our electrolyzer and the opening of the hydrogen landscape here in Bamberg mark an important milestone for us”, added Markus Heyn, member of the Bosch board of management and chairman of the Mobility business sector.
