At the Berlin plant, units of the water electrolysis hydrogen production equipment are combined into functional modules, or “electrolyzers”, after production. Depending on the required capacity, these modules will then be assembled into larger process units. The final assembly process will be carried out in Mulheim to complement the Berlin plant and, most importantly, to enable mass production of the production line to provide affordable and economical water electrolysis equipment. This is a prerequisite for meeting the growing demand for hydrogen energy and reducing the cost of hydrogen production.

Siemens Energy uses proton exchange membrane (PEM) water electrolysis technology to produce hydrogen, which uses a proton exchange membrane and electricity from renewable energy sources to split water into hydrogen and oxygen. The process has high electrolytic efficiency, high gas purity, reliable operation, and no chemical substances or impurities. Siemens Energy’s advanced high-power PEM electrolysis water hydrogen product line is also optimized for large-scale applications up to hundreds of megawatts, producing several tons of green hydrogen per hour. The electricity used in the production of the water electrolysis hydrogen production equipment will also come entirely from renewable energy sources.

Hydrogen energy is the key to achieving the goal of decarbonization

Green hydrogen, which is hydrogen produced from renewable energy sources, is a key part of the renewable energy alternative to fossil fuels. Hydrogen can be used both as an energy storage medium and as a raw material for other applications, such as synthetic fuels. It can also be used directly for power generation and heating instead of natural gas. With the large-scale development of renewable energy, hydrogen energy will be the key to ensuring the success of the energy transition. The production of green hydrogen and its derivatives is already well known, and the task now is to scale up production to an industrial scale, and the high-power water electrolysis plant to be produced in Berlin will be the key core of green hydrogen production technology.
