Bosch commissions its first in-house electrolyzer with Hybrion electrolysis stacks

November 6, 2025 |

In Germany, Bosch said that after officially launching Hybrion PEM electrolysis stacks in March, the firm 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, the firm said.

“Hydrogen plays a central role in a climate-neutral world, which is something we’re committed to achieving as a society in Germany and Europe, and it’s an ideal energy source. It can be produced, stored, and transported almost anywhere, and in a climate-neutral way”, said Markus Heyn, member of the Bosch board of management and chairman of the Mobility business sector.

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.

“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,” the executive added.
