Neptune Energy, a UK-based independent company, will host the world’s first offshore green hydrogen project – PosHYdon – on an active oil or gas platform in the Dutch North Sea. The project will be hosted 13 km off the coast of Scheveningen.

The hydrogen plant on the platform will be powered by electricity supplied by offshore wind turbines, which will transform saltwater into demineralized water and subsequently create hydrogen via electrolysis. The goal is to acquire expertise in integrating functional energy systems at sea as well as hydrogen generation in an offshore setting.

The efficiency of an electrolyzer with a variable supply from offshore wind will also be evaluated, and information and insights into installation and maintenance costs will be gained. The green hydrogen will be combined with the gas and delivered to the shore via the existing gas pipeline. The 1 MW electrolyzer will be capable of producing up to 400 kg of green hydrogen each day. Neptune has received a €3.6 million ($4.25 million) grant from the Netherlands Enterprise Agency, which will allow the partnership to begin work on the project. The grant was made possible via the agency’s Demonstration Energy and Climate Innovation initiative, which funds renewable energy projects such as hydrogen pilots. The platform’s partners include operator Neptune (50 per cent), EBN (40 per cent), and Taqa (10 per cent).
