Siemens Energy to invest in Berlin electrolyser facility

Facility will produce 500MW and larger electrolysers from 2023 as firm looks to expand hydrogen business

Technology firm Siemens Energy will invest €30mn ($34mn) to convert its gas turbine manufacturing facility in Berlin to produce industrial-scale proton-exchange-membrane (PEM) electrolysers. Individual electrolyser cells will be manufactured and combined to form stacks of 500MW and larger. Depending on the required capacity, these will then be assembled into deployable units for industry at a separate facility in Berlin. “With the new production facility for hydrogen electrolysers, we are reinforcing our claim to play an active role in shaping the energy transition,” says Christian Bruch, CEO of Siemens Energy. “For this to be economically viable, the manufacturing costs for electrolysers mu
