Siemens launches 8.75-MW electrolyser in Bavaria

Siemens AG (ETR:SIE) this week announced the commissioning of an 8.75-MW proton exchange membrane (PEM) electrolyser in Wunsiedel, Bavaria.

The completion of one of the largest green hydrogen production plants in Germany comes around one year after the groundbreaking for the facility.

It will produce up to 1,350 tonnes of hydrogen a year from solar and wind power in the Wunsiedel Energy Park. The hydrogen will be distributed by truck trailers for use mainly in the region’s industrial and commercial businesses.

The hydrogen facility will be connected to an existing Siemens battery and to adjacent industrial enterprises, which can consume the waste heat or the oxygen from the electrolysis. In addition, a hydrogen filling station at the site is due to be completed next year.

The project uses Siemens Energy’s Silyzer 300 PEM technology and Siemens Smart Infrastructure acted as the general contractor. The operating company, WUN H2, is owned by Siemens Financial Services and Riessner-Gase, each holding 45%, and utility Stadtwerke Wunsiedel (SWW) with 10%.

“With global warming, energy dependency and rising costs becoming increasingly pressing issues, real-world solutions for the future of energy are crucial,” said Siemens Smart Infrastructure chief executive Matthias Rebellius. “The Wunsiedel project is an excellent demonstration of how vision and initiative combined with the right technology and financing can drive forward the development of a carbon-free power supply,” the executive added.

Separately, on Thursday, Siemens announced a memorandum of understanding between Siemens Smart Infrastructure and Shell Global Solutions International BV to collaborate on energy transition solutions with a focus on projects that produce green hydrogen for industrial use at Shell and its customers.
