ZAMUDIO, Spain – Siemens Gamesa and Siemens Energy have joined 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.
The companies intend to provide a full-scale offshore demonstration of the solution by 2025/2026.
Over five years, Siemens Gamesa said it plans to invest EUR 80 million ($97 million) and Siemens Energy is targeting to invest EUR 40 million ($49 million) in the developments.
Siemens Gamesa will adapt its development of the SG 14-222 DD offshore wind turbine to integrate an electrolysis system into the turbine’s operations. Siemens Energy will develop a new electrolysis product.
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.
According to the companies, the solution will lower the cost of hydrogen by being able to run off grid, opening up more and better wind sites. The companies’ developments will serve as a test bed for making large-scale, cost-efficient hydrogen production a reality. They are also expected to prove the feasibility of reliable, effective 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.
