Siemens Gamesa and Siemens Energy Kick-Start Green Hydrogen Co-Op

Siemens Gamesa and Siemens Energy are joining forces to develop a solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to directly produce green hydrogen.

Siemens Gamesa will adapt its development of SG 14-222 DD – the world’s most powerful offshore wind turbine – to integrate an electrolysis system seamlessly into the turbine’s operations.

Siemens Energy will develop a new electrolysis product to meet the needs of the maritime offshore environment and be in sync with the turbine, but also 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.

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.

The developments aim to serve as a testbed for making large-scale hydrogen production a reality and prove the feasibility of the implementation of wind turbines in systems for producing hydrogen from renewable energy.

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

Additionally, the German Federal Ministry of Education and Research stated that the developments can be implemented as part of the ideas competition Hydrogen Republic of Germany.

“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,” said Andreas Nauen, Siemens Gamesa CEO.

“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.”
