Siemens Smart Infrastructure and WUN H2 GmbH have built one of the largest hydrogen production plants in Germany, in Wunsiedel in the north of Bavaria. The plant runs solely on renewable energy and is CO2-free. It has a nominal capacity of 9 MW and produces up to 1,350 tons of green hydrogen per year.

Developing and implementing a holistic concept for hydrogen supply: 

• Construction of local, turnkey PEM electrolysis with an installed power of 8.75 MW – completely supplied from renewable energy sources. 
• Siemens supports the entire process including simulation, planning, construction, operation and monitoring of the facility. 
• Establishing an operating company (Siemens AG holds a stake of 45%).
