Hynamics UK, a subsidiary of EDF Group, and Hy24 have partnered to advance the development of the Fawley green hydrogen project, to be situated beside the Esso Fawley refinery in Hampshire, England.

The project was selected in the UK government’s subsidy scheme, Hydrogen Allocation Round 2 (HAR2), in April 2025.

Hy24, through its clean hydrogen infrastructure fund, will engage in exclusive negotiations to fund a £300m ($407m) hydrogen electrolytic production facility.

Hy24 UK, Southern Europe and MENA head Amir Sharifi stated: “The policy landscape in the UK is providing the certainty and clarity needed to enable decarbonisation 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.”

The project will supply ExxonMobil’s petrochemical complex with green hydrogen as it seeks decarbonisation solutions.

The proposed project will include a 120MW electrolyser, which could potentially save up to 100,000t per year of CO₂ by replacing heavy fuel oil and grey hydrogen with its low-carbon hydrogen.

Hynamics UK CEO Pierre de Raphélis-Soissan stated: “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 [2025] and is a testimony to the potential for cooperation between industrial and financial players across the Channel.”
