PosHYdon: the world's first green hydrogen pilot

Neptune Energy’s Q13a drilling platform is home to PosHYdon, the world’s first offshore green hydrogen pilot. To produce hydrogen, seawater on the platform is first converted into demineralised water. Wind power is then used to produce the green hydrogen.

The pilot is a spin-off of the North Sea Energy programme: a research consortium of more than 30 parties from the energy sector. The aim is to develop relevant knowledge and use this to make the right choices for a new, flexible and integrated energy system. The North Sea Energy programme aims to make the best possible use of the synergy benefits resulting from the integration of existing and new energy systems.
 
Expertise center InVesta has joined the PosHYdon consortium as a partner. For PosHYdon, InVesta will be the onshore test site prior to offshore installation. The test phase has started in May 2024 and is expected to be completed by the end of this year (see news item May 8, 2024). The results of PosHYdon are an important knowledge base for two demonstration projects that EZK has planned. The intention is that developers, grid operators, suppliers and other stakeholders gain experience with the production and transport of hydrogen at sea, both the technology, environmental effects and costs and revenues of construction, operation and maintenance.

Status:

Onshore test phase at Investa successfully completed in the first half of 2024, PosHYdon live at sea since the second half of that year.
