    Siemens Gamesa reported it has reached a new milestone at its Brande Hydrogen pilot project site in Denmark.

    The renewable energy company said It has produced the first green hydrogen in its testing and commissioning phase in “island mode” and distributed it to hydrogen stations across the country through project partner Everfuel. The firm has installed a battery, turbine and electrolyzer set up at the site, connecting it to an existing Siemens Gamesa SWT 3.0-113 DD wind turbine.

    The wind turbine has an electrolyzer stack from Green Hydrogen Systems. The combination of a battery, turbine and an electrolyzer will ensure a reliable supply of green hydrogen. It has the potential to produce industrial-scale volumes of green hydrogen and expand to other existing wind projects. The setup can also connect to the grid, ensuring greater flexibility in electricity supply.

     Danish authorities had granted the site an official regulatory test zone status, facilitating the site to operate outside the existing electricity regulations. It facilitated the research and development of an island-mode capable system of offshore hydrogen production at the turbine level. Learnings from this project can be shared with partners to build the use case for the large scale production of green hydrogen.
