The Danish authorities designated Siemens Gamesa’s Brande Hydrogen test facility as an official regulatory test zone earlier this summer, allowing activities to take place outside of existing power rules.

This has made it possible to do research on how to construct an island-mode competent offshore hydrogen generation system at the turbine level.

An existing onshore Siemens Gamesa SWT 3.0-113 DD wind turbine is combined with an electrolyzer stack from electrolysis partner Green Hydrogen Systems in the Brande Hydrogen configuration.

Siemens Gamesa is also utilizing the Brande Hydrogen facility to investigate if incorporating new battery technology as an addition to the co-located turbine and electrolyzer will help with grid stability and wind unpredictability.

This combination may also be used to boost the production of existing wind farms.

Batteries can store energy in such a manner that electrolyzers can operate for longer periods of time and create more green hydrogen.

When conditions allow, the batteries can send renewable energy to the grid rather than the electrolyzer if there is a grid connection, reducing bottlenecks and increasing flexibility.

In the near future, the battery, turbine, and electrolyzer arrangement might enable the generation of industrial-scale amounts of green hydrogen.

The Brande Hydrogen test site’s innovations and lessons will be shared with partners in order to develop use cases for larger-scale green hydrogen generation.

Everfuel, one of the project’s partners, will now supply it to hydrogen stations in Denmark.

This will allow an increasing number of zero-emission vehicles, such as fuel cell taxis, to run entirely on renewable energy.

Without industrial-scale production of green hydrogen, the world will not reach carbon neutrality by 2050, and global temperatures will continue to increase.

Green hydrogen is a 100 percent sustainable and adaptable fuel that can be stored and transported for use on demand and is created from low-cost, competitive wind power.
