Hynamics UK and Hy24 in partnership to develop UK’s Fawley green hydrogen project
Hynamics UK, a 100% subsidiary of EDF Group specialising in low-carbon and renewable hydrogen production, and Hy24, the world’s leading low-carbon hydrogen asset manager, have signed a Memorandum of Understanding (MoU) to enter an exclusive partnership to pursue the development and funding of the Fawley green hydrogen project. The project has been shortlisted in the UK government’s Hydrogen Allocation Round 2 (HAR2) subsidy scheme.
Hynamics and Hy24 are aiming to establish a broader partnership in the UK.
The agreement between Hynamics and Hy24 was formalised recently, during the State visit to the UK of the French President.
This MoU marks the beginning of exclusive negotiations with Hy24, through its Clean Hydrogen Infrastructure Fund, to develop and finance a £300 million hydrogen electrolytic production facility in Fawley, located in Hampshire, England. The project aims to supply green hydrogen to the ExxonMobil petrochemical complex as part of its decarbonisation strategy.
In addition, Hynamics UK and Hy24 reaffirmed their shared commitment to accelerating the deployment of low-carbon hydrogen across the UK’s industrial sectors. They also expressed their intention to collaborate on a broader range of projects developed by Hynamics UK, aligning with the UK government’s ambitions for clean energy development.
Hynamics UK was shortlisted in April 2025 in the government’s HAR2 for its Fawley Green Hydrogen Project, to be located on land adjacent to the Esso Fawley refinery.
The project will consist of a 120 MW electrolyser participing in the decarbonisation of this national strategic infrastructure. Employing over 2,500 staff and contractors, the ExxonMobil Fawley refinery is the largest complex of its kind in the UK, with 1 in 4 vehicles using Fawley road fuels and providing more than 20% of the UK’s aviation fuel, including a quarter of Heathrow’s need.
This ambitious first-of-a-kind opportunity aims to reduce up to 100 000 tonnes/year of CO2 emissions by replacing heavy fuel oil and grey hydrogen with low-carbon hydrogen.
