Siemens Gamesa and Siemens Energy join forces for offshore Hydrogen

Siemens Gamesa and Siemens Energy are joining forces combining their ongoing wind to hydrogen developments. The companies are contributing with their developments to developing a solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to directly produce green hydrogen.

Over a time frame of five years, Siemens Gamesa plans to invest EUR 80 million and Siemens Energy is targeting to invest EUR 40 million 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 into the turbine’s operations. Siemens Energy will develop a new electrolysis product to meet the needs of the harsh maritime offshore environment and sync with the wind turbine.

“Our more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energy’s expertise in electrolyzers, brings together brilliant minds and cutting-edge technologies to address the climate crisis. Our wind turbines play a huge role in the decarbonization 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, explains: “Together with Siemens Gamesa, we are in a unique position to develop this game changing solution. We are the company that can leverage its highly flexible electrolyzer technology and create and redefine the future of sustainable offshore energy production. 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.”

The fully integrated offshore wind-to-hydrogen solution will produce green hydrogen using an electrolyzer array located at the base of the offshore wind turbine tower. The solution is expected to lower the cost of hydrogen by being able to run off grid, opening up more and better wind sites. The companies developments will aim to serve as a test bed for making large-scale, cost-efficient hydrogen production a reality and will to prove the feasibility the implementation of wind turbines in systems for producing hydrogen from renewable energy.

The developments are part of the H2Mare initiative which is a lighthouse project likely to be supported by the German Federal Ministry of Education and Research ideas competition "Hydrogen Republic of Germany". The H2mare initiative under the consortium lead of Siemens Energy is a modular project consisting of multiple sub-projects to which more than 30 partners from industry, institutes and academia are contributing. Siemens Energy and Siemens Gamesa will contribute to the H2Mare initiative with their own developments in separate modular building blocks.

The companies intend to provide a full-scale offshore demonstration of the solution by 2025/2026.
