“Green” hydrogen Made in Wunsiedel

Successful partnership technology

When hydrogen is produced from water electrolysis using only power from renewable energy sources, it is known as “green” hydrogen. A Silyzer 300 from Siemens Energy will be used in Wunsiedel. The plant will feature high efficiency at high power density as well as low-maintenance and reliable operation – without chemicals. The PEM electrolysis process will be applied, in which electricity is used to split water into hydrogen and oxygen. The PEM, or proton-exchange membrane, allows protons to pass through but stops gases such as hydrogen or oxygen. In an electrolytic process, the membrane functions as a separator, among other things, and prevents the resulting gases from mixing. Compared to traditional alkali electrolysis, PEM technology is ideally suited for utilizing fluctuating wind and solar electricity because of its highly dynamic method of operation.

“For the first time, the oxygen and the low-temperature waste heat generated during production are planned to be reused by nearby industrial operations. This will result in maximum energy efficiency and a plant that is unique because all element flows will be utilized. In addition, electrolysis is an important building block toward implementing the ‘WUNsiedeler Weg – energy’, where we make sustainably energy use and climate protection a reality,” explained Marco Krasser, CEO of SWW Wunsiedel GmbH. It’s clear that our whole team is focused on making tomorrow different today. “I think we’d all like to live in a world where everybody has access to clean and reliable electricity,” says Hamed. “I want my children to live in a better world. Everyone at Siemens Energy is committed to reducing the carbon footprint and serving society, because we are all a part of society. It’s as simple as that!”

Germany’s Minister of Environmental Affairs, Thorsten Glauber concluded: “Hydrogen is a key technology on the road to a climate-neutral future. The energy transition will only succeed if there are many innovative approaches like the one pursued in Wunsiedel.”
