Siemens Energy and Siemens Gamesa are developing a commercial offshore wind turbine in Germany that produces hydrogen via electrolysis, the companies said, making it a breakthrough in the mass production of renewable hydrogen.

The companies are investing 120 million euros ($146 million) in the system, which has not been previously reported.

In the European Union, renewable hydrogen, which can replace fossil fuel in sectors that are struggling at decarbonisation, is seen as a way to meet goals for emission reduction.

The joint effort of the companies aims to integrate electrolyser technology, which is needed to produce hydrogen, in offshore turbines.

Green hydrogen is developed by splitting water into its two components using electricity from renewable energy sources, such as wind and solar, instead of cheaper grey hydrogen, which is produced via fossil fuels.

The plans by Siemens Energy and Siemens Gamesa are supported by the German government, which has earmarked 9 billion euros ($10,865 million) to kickstart a national hydrogen industry to become a global leader in the field.

Germany, which borders the North and Baltic Seas, would be a good location for a first commercial project, Siemens Gamesa's Nauen said.

Thyssenkrupp and Salzgitter and other industrial firms are looking to hydrogen technology to help them significantly reduce the carbon footprint.

Siemens Energy said offshore wind turbines that can produce hydrogen are one of many ways to reach net-zero emissions.
