World’s first offshore green hydrogen project on working platform.

Neptune Energy will host PosHYdon project offshore the Netherlands.

UK independent Neptune Energy will host the world's first offshore green hydrogen project on an operational oil or gas platform on one of its facilities offshore the Netherlands.

PosHYdon, which will be hosted on the Neptune Energy-operated Q13a-A platform, aims to validate the integration of offshore wind, offshore gas and offshore hydrogen in the Dutch North Sea.

Electricity generated by offshore wind turbines will be used to power the hydrogen plant on the Q13a-A platform, converting seawater into demineralised water, then into hydrogen via electrolysis. The aim of the pilot is to gain experience of integrating working energy systems at sea and the production of hydrogen in an offshore environment.

In addition, in this project the efficiency of an electrolyser with a variable supply from offshore wind will be tested, and at the same time knowledge and insights on the costs for the offshore installation as well as maintenance costs will be obtained.

The green hydrogen will be mixed with the gas and transported via the existing gas pipeline to the coast. The 1-megawatt electrolyser will produce a maximum of 400 kilogrammes of green hydrogen per day.

Neptune on Thursday said it welcomed the 3.6 million euros (US$4.25 million) subsidy from the Netherlands Enterprise Agency for the PosHYdon project, that will be installed on its Q13a-A platform.

The subsidy was awarded under the RVO’s Demonstration Energy and climate Innovation (DEI+) scheme, which invites funding applications for investments in renewable energy developments, including hydrogen pilots. With this subsidy the consortium can start up all activities for this pilot. The remaining budget will be funded by the consortium partners - Nel Hydrogen, InVesta, Hatenboer, IV-Offshore & Energy, Emerson Automation Solutions. Nexstep, TNO, Neptune, Gasunie, Noordgastransport, NOGAT, DEME Offshore, Taqa and Eneco. (July 21, 2021)
