Siemens Energy to start producing hydrogen electrolysers

Published by
Global Hydrogen Review,


Siemens Energy will locate the industrial production of electrolysis modules in Berlin and is thus taking the centerpiece of its hydrogen technology to the capital. Start of production at the location Huttenstrasse in Berlin’s Moabit locality is scheduled for 2023. At this site the complete infrastructure of an existing production hall can be used. New production lines for the electrolyzers are being set up on 2000 m2 at a cost of approximately €30 million.

Presently, the site mainly manufactures gas turbines, which are among the most powerful and efficient in the world. These can already be operated with up to 50% hydrogen, and by 2030 complete hydrogen operation should be possible. Siemens Energy is now pooling its expertise in both these areas in Berlin to ensure a reliable and successful energy transition to a new energy mix. This also includes the business field of energy transmission. At the Siemens Energy Switchgear Plant Berlin, innovative high voltage products are manufactured, ensuring that electricity reaches consumers reliably.

Christian Bruch, President and CEO of Siemens Energy, comments: “With the new production facility for hydrogen electrolysers, we are reinforcing our claim to play an active role in shaping the energy transition. To this end, we are pooling our knowledge in the field of various energy technologies in Berlin. For us, hydrogen is an important component of the future energy world. For this to be economically-viable, the manufacturing costs for electrolysers must be significantly reduced. With our new production facility, we are helping to make hydrogen competitive sooner.”

At the Berlin location, the individual electrolyser cells will be manufactured and combined to form functional modules, or 'stacks'. Depending on the required capacity, these will then be assembled into larger process-based units. In Germany, this last stage will take place at Mülheim, which is closely associated with the new Berlin plant and complements it perfectly. The critical element is that production is being switched over to mass production: reasonably priced and affordable electrolysers are the prerequisite for being able to cover growing demand and the future costs of hydrogen.

For this purpose, Siemens Energy is relying on proton exchange membrane (PEM) electrolysis, in which water is separated into hydrogen and oxygen using a proton-permeable membrane and electricity from renewable sources. The key aspects of this process are its high level of efficiency, high product gas quality, and reliable operation with no chemicals or impurities. The latest and most powerful PEM electrolyser product line from Siemens Energy is optimised for applications up to the high hundreds of megawatts, enabling systems of this size to generate several tph of green hydrogen. The electricity used in electrolyser manufacture will be sourced entirely from renewables.
