Siemens to Build Hydrogen Generation Plants in Wunsiedel
The official groundbreaking ceremony in Wunsiedel marked the start of construction of a hydrogen generation plant with a capacity of 8.75 megawatts. The facility will produce up to 1,350 tons of hydrogen per year using only renewable energy, for example from solar or wind power. Using the generated hydrogen in transportation and industry allows for CO 2 savings of up to 13,500 annually. Siemens Smart Infrastructure is the general contractor for the entire plant, with Siemens Financial Services participating in the equity financing as well as holding a share of 45 percent in the operating company WUN H2 GmbH. The electrolyzer will be supplied by Siemens Energy.
The plant will be constructed at Wunsiedel Energy Park and connected to the existing Siemens battery storage facility and adjacent industrial enterprises. These can use waste heat, or the oxygen split off during electrolysis. This connected infrastructure will serve as a model for the whole of Germany.
For the project in Wunsiedel, SFS, the financing arm of Siemens, is in charge of commercial project development and structuring the financing. SFS holds a 45 percent share in the project’s operating company WUN H2; Rießner Gase GmbH also holds 45 percent and Stadtwerke Wunsiedel (SWW) the remaining 10 percent. At the same time, SFS was able to implement non-recourse project financing, i.e. without counter-liability to the shareholders, with UmweltBank as an external lender to secure financing for the project.
If hydrogen is produced through the electrolysis of water by only using power from renewable energy sources for this process, it is referred to as “green”, i.e. carbon-free hydrogen. The Wunsiedel plant uses Siemens Energy’s most advanced electrolyzer
The hydrogen is delivered via truck trailers to local and regional end customers for local distribution, mainly in the regions of Upper Franconia, Upper Palatinate, Thuringia and Saxony as well as Western Bohemia (Czech Republic). The plant also helps alleviate grid bottlenecks and provides flexibility for the power grid. The option to build a public hydrogen filling station for trucks and buses at the same location will make it possible to create an offering for carbon-free heavy goods transportation as well as regional public transportation.
