Hynamics UK and Hy24 sign exclusive partnership to develop UK's Fawley Green Hydrogen project

MoU covers development and funding of Fawley Green Hydrogen Project with the ambition to codevelop additional UK projects

On the eve of the UK-France Summit 2025, 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 United Kingdom.

The agreement between Hynamics and Hy24 was formalised on July 8th, during the State visit to the UK of the French President. This Memorandum of Understanding (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.

The Fawley Green Hydrogen project: potential 100 000 tons of CO2/year saving initiative

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 2500 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 tons/year of CO2 emissions by replacing heavy fuel oil and grey hydrogen with low-carbon hydrogen.

CEO of Hynamics UK, Pierre de Raphélis-Soissan, said: “I am delighted with this partnership with Hy24, which marks a new stage in the development of Hynamics' projects in the United Kingdom. This agreement is a continuation of the relationship of trust that has been built up over several years. Our MoU is in line with the Clean Industrial Strategy presented by the British Government in June and is a testimony to the potential for cooperation between industrial and financial players across the Channel.”

Amir Sharifi, Comex member & Strategy Lead at Hy24, Head of UK, Southern Europe and MENA, added: “The policy landscape in the UK is providing the certainty and clarity needed to enable decarbonization projects at the right scale and pace. We see this as a very positive signal and a strong opportunity for Hy24 to expand into the UK for the first time, alongside partners who are deeply committed to the energy transition. The reality is that leadership positions across the hydrogen value chain are being shaped now- and the UK has shown remarkable consistency and determination in this regard. In this context, Hynamics UK stands out as one of the most advanced players, and we are pleased to solidify our partnership with them to help accelerate the development of the UK’s hydrogen economy.”

Notes to editors

The UK-France Summit underlines the strategic importance of cooperation between UK and France in energy matters, including renewables and low-carbon hydrogen. The Summit follows France's revised National Hydrogen Strategy, adopted in April, that repositioned the nation as a major player in decarbonisation on a global scale. In addition, the UK government recently launched its new Industrial Strategy with hydrogen identified as playing a key role in the 10 year plan. This builds on the stable and consistent regulatory framework that the UK government has already put in place, that fosters investor confidence in clean hydrogen projects.

This move by Hy24 further complements Ardian’s long-term commitment to supporting the UK’s net-zero ambitions, building on recent strategic investments in sustainable growth in aviation (Heathrow) and green digital infrastructure (Verne).
