Siemens Gamesa and Siemens Energy to unlock a new era of offshore green hydrogen production

Siemens Gamesa and Siemens Energy will combine their ongoing wind-to-hydrogen developments as part of an effort to decarbonise the economy and solve the climate crisis.

The two companies today (13th Jan) announced the partnership, through which they hope to develop an innovative solution that fully integrates an electrolyser into an offshore wind turbine as a single synchronised system to directly produce green hydrogen.

As part of its role in the partnership, Siemens Gamesa will adapt its development of the “world’s most powerful” turbine, the SG 14-222 DD offshore wind turbine, to integrate the electrolysis system into the turbine’s operations.

By leveraging Siemens Gamesa’s knowledge and 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-to-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.

Once complete, the fully integrated offshore wind-to-hydrogen solution will produce green hydrogen using an electrolyser array located at the base of the offshore wind turbine tower, blazing a trail towards offshore hydrogen production. The solution will lower the cost of hydrogen by being able to run off grid, opening up more and better wind sites.

The parties to provide a full-scale offshore demonstration of the solution by 2025/2026. Siemens Gamesa plans to invest €80m and Siemens Energy is targeting to invest €40m in the developments.

Commenting on the partnership, Andreas Nauen, Siemens Gamesa CEO, said, “Our more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energy’s expertise in electrolysers, 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.”

Christian Bruch, CEO of Siemens Energy, added, “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 electrolyser 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.”
