Siemens Gamesa and Siemens Energy to develop offshore green hydrogen

Siemens News pageSiemens Gamesa and Siemens Energy are joining forces to hydrogen developments to address one of the major challenges — decarbonising the economy to solve the climate crisis

The companies are contributing with their developments to an innovative solution that fully integrates an electrolyser into an offshore wind turbine as a single synchronised system to directly produce green hydrogen. 

The aim is to provide a full-scale offshore demonstration of the solution by 2025/2026. The German Federal Ministry of Education and Research announced today that the developments can be implemented as part of the ideas competition “Hydrogen Republic of Germany.”

“Our wind turbines play a huge role in the decarbonisation of the global energy system, and the potential of wind to hydrogen means that we can do this for hard-to-abate industries too. It makes me very proud that our people are a part of shaping a greener future,” said Andreas Nauen, Siemens Gamesa CEO.

Christian Bruch, CEO of Siemens Energy, explained, “With these developments, the potential of regions with abundant offshore wind will become accessible for the hydrogen economy. It is a prime example of enabling us to store and transport wind energy, thus reducing the carbon footprint of economy.”

Over a timeframe of five years Siemens Gamesa plans to invest US$96.55mn and Siemens Energy is targeting to invest US$48.27mn in the developments. Siemens Gamesa will adapt its development of the world’s most powerful turbine, the SG14-222 DD offshore wind turbine to integrate an electrolysis system seamlessly into the turbine’s operations. By leveraging Siemens Gamesa’s intricate knowledge and decades of experience with offshore wind, electric losses are reduced to a minimum, while a modular approach ensures a reliable and efficient operational set-up for a scalable offshore wind-hydrogen solution. Siemens Energy will develop a new electrolysis product to not only meet the needs of the harsh maritime offshore environment and be in perfect sync with the wind turbine, but also to create a new competitive benchmark for green hydrogen.
