Siemens Gamesa’s Brande Hydrogen pilot project has started producing its first green hydrogen as part of the testing and commissioning phase in Denmark.
The project now produces green hydrogen distributed to Everfuel’s hydrogen refuelling stations in Denmark as part of the commissioning phase.
Brande Hydrogen is linked to an existing onshore Siemens Gamesa SWT 3.0-113 DD wind turbine with an electrolyser stack from electrolysis partner Green Hydrogen Systems. The project aims to conduct tests and experiments for showing that green hydrogen can be produced without using any energy from the grid, known as ‘island mode.
The project also explores whether integrating new battery technology to upgrade the co-located turbine and electrolyser can contribute to grid stability to tackle the wind variability issue. This combination can potentially expand the output of existing wind projects as batteries can store energy, allowing electrolysers to run for longer and producing more green hydrogen. Moreover, batteries can also distribute renewable energy to the grid rather than electrolysers. The battery, turbine and electrolyser setup can enable the production of industrial-scale volumes of green hydrogen in the near term.
Earlier this summer, the Danish authorities granted Siemens Gamesa’s Brande Hydrogen test site status as an official regulatory test zone, allowing activities to operate outside the existing electricity regulations and enabling research into developing an island-mode capable system of offshore hydrogen production at turbine level.
