  • Projects target a total investment of approximately EUR 120 million over five years in developments leading to a fully integrated offshore wind-to-hydrogen solutionย  ย ย 
  • Projects are first major step to develop an industrial-scale system capable of harvesting green hydrogen from offshore windย ย 
  • Developments will enable decarbonization of hard-to-abate sectors such as transport and heavy industryย ย 
  • Implementation within the framework of the ideas competition “Hydrogen Republic of Germany” of the Federal Ministry of Education and Researchย 

Siemens Gamesa and Siemens Energy announced today that they are joining forces combining their ongoing wind-to-hydrogen developments to address one of the major challenges of our decade โ€” decarbonizing the economy to solve the climate crisis. ย  ย 

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

โ€œOur more than 30 years of experience and leadership in the offshore wind industry, coupled with Siemens Energyโ€™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,โ€ said Andreas Nauen, Siemens Gamesa CEO.

Christian Bruch, CEO of Siemens Energy, explains: โ€œTogether 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.โ€

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 worldโ€™s most powerful turbine, the SG 14-222 DD offshore wind turbine, to integrate an electrolysis system seamlessly into the turbineโ€™s operations. By leveraging Siemens Gamesaโ€™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-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.

The ultimate 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, 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 companiesโ€™ developments will serve as a test bed for making large-scale, cost-efficient hydrogen production a reality and will prove the feasibility of reliable, effective implementation of wind turbines in systems for producing hydrogen from renewable energy.
