Project with Siemens Gamesa

Project with Siemens Gamesa Renewable Energy. HyProvide A90 electrolyser for on-site hydrogen generation. Complete turnkey delivery and commissioning by GHS.

As part of a pioneering wind-to-hydrogen project, Green Hydrogen Systems’ electrolyser was connected to a Siemens Gamesa 3 MW wind turbine near Brande, Denmark.

In conventional wind turbine operation, the turbine is connected to the power grid, and the energy it produces must be consumed immediately or go to waste. With this project, Siemens Gamesa operates the turbine in “island mode.”

Instead of feeding the power grid, the wind turbine feeds electricity into a GHS HyProvide A-Series electrolyser, which converts the electricity into hydrogen that will be stored for subsequent distribution and use as a fuel for hydrogen-powered buses, taxis and cars.

This successful island-mode production will constitute a major step forward for the industry – and sustainable energy in general.
