Green hydrogen pilot PosHYdon successfully kicks off onshore testing

The PosHYdon pilot successfully kicked off its onshore testing at the InVesta premises in Alkmaar, the Netherlands. PosHYdon aims to produce green hydrogen on an operational gas platform in the Dutch North Sea. This will mark the first integration of three offshore energy systems, where hydrogen will be transported to land along with gas via an existing pipeline.

The pilot is seen as essential for the development of large-scale green hydrogen production at sea, contributing significantly to the energy transition in the Netherlands and Northwest Europe. After this onshore testing period, the electrolyzer will be moved offshore to the Q13a-A platform, located 13 kilometers off the coast of Scheveningen. The first offshore hydrogen production is scheduled for Q4 of this year.

René Peters, Business Director Gas Technologies at TNO and initiator of the North Sea Energy Program, said: “PosHYdon is a perfect example of system integration in the North Sea. In many studies, hydrogen is considered the missing link in the energy transition, with many talking about all the opportunities. But here, right off the coast of Scheveningen, it will actually take place later this year. PosHYdon is teaching us a lot about the next steps that need to be taken towards safe, large-scale green hydrogen production from wind at sea. Offshore green hydrogen production will enable large-scale wind farms to be developed far out at sea. Wind energy is directly converted to green hydrogen from demineralized seawater and can be transported through the existing or new gas infrastructure. As a result, offshore wind projects can be realized faster at significantly lower costs for society. I am therefore very happy that we can now test the complete installation onshore, in preparation for transferring it offshore for the final test: offshore green hydrogen production.”

In addition, PosHYdon will also participate in a pilot for Guarantees of Origin for green hydrogen and the upcoming migration towards European hydrogen certification. This pilot, which is open to others, is being planned through HyXchange. Neptune Energy (Eni) previously participated in the HyXchange certification pilot in 2022.
