Eni is a key player in the UK's energy transition, with a strong footprint across the entire energy value chain. This spans from carbon capture and storage (CCS) to Offshore Wind, Fusion Energy and Upstream operations. We have launched strategic projects for the decarbonisation of several industrial areas in the country, with the aim of achieving carbon neutrality. We are a leading company in the transportation and storage of CO2, as part of the HyNet CCS cluster in North West of England and North Wales, which will be pivotal for the UK’s journey towards a Net Zero future as one of the world’s first low-carbon industrial clusters. In the CCS space, we have also launched the Bacton Thames Net Zero initiative to contribute to the decarbonisation of the most polluting industrial processes in the South East of England.
We are active in the production of electricity from offshore wind power thanks to the Dogger Bank project, which will be the biggest of its kind in the world when fully operational, and are leading the development of the groundbreaking floating offshore wind plant Green Volt. We are also partnering with the UK authorities to accelerate the commercialisation of Fusion Energy. In the Upstream segment, we completed a business combination with Ithaca Energy in October 2024, and actively contribute to the UK’s energy security.

How we operate in the country
HyNet North West and Hewett, our decarbonisation projects
With the aim of transforming one of the UK’s most energy-intensive districts into one of the world’s first low-carbon industrial cluster, the Liverpool Bay CO2 Transport and Storage infrastructure will be pivotal for the country’s journey towards a Net Zero Future. As part of the HyNet cluster in the North West of England and North Wales, we will be actively involved in the development and management of the onshore and offshore CO2 transport and storage. The initiative will allow CO2 to be captured from industrial emitters and injected into new and repurposed pipelines for permanent and safe storage in our depleted reservoirs located about 30 kilometers off the coast in Liverpool Bay. Decommissioning and repurposing infrastructure started in 2025, with start-up of injecting CO2 planned for 2028 with initial target storage capacity of 4.5 million tonnes per year (mtpa), increasing to 10 mtpa in the 2030s. We also hold an additional carbon dioxide storage license from the UK Authorities for the Hewett depleted gas field, where we plan to develop a CCS project that will contribute to the decarbonisation of the Bacton and Thames Estuary area. The Hewett project is ideally located to potentially attract CO2 volumes from the European Union.
Developments in the renewable energy business
We operate in the UK offshore wind power generation market through Vårgrønn, a company 65% owned by Plenitude and 35% owned by the Norwegian fund HitecVision. Vårgrønn holds a 20% stake in the Dogger Bank project, together with partners Equinor and SSE Renewables. Dogger Bank started production in October 2023 and is the largest marine wind farm under construction. The project is divided into three phases (A, B and C), each with a capacity of 1.2 GW, and involves the installation of 277 latest-generation 13 MW turbines at a distance of over 130 km from the country’s north-eastern coastline for a total capacity of 3.6 GW. When fully operational, Dogger Bank will be able to produce enough renewable electricity to supply approximately six million homes.
Moreover, Vårgrønn, together with its partner Flotation Energy, signed an ‘Exclusivity Agreement’ with Crown Estate Scotland for the development of two offshore floating wind farms with a capacity of up to 1.9 GW, named GreenVolt and Cenos. The initiative is part of the INTOG (Innovation and Targeted Oil and Gas) leasing round, which aims to provide renewable electricity to the UK grid, thus benefitting UK consumers and industry, while allowing the electrification and decarbonisation of O&G platforms in the northern North Sea, with the aim of reducing asset emissions. Notably, in September 2024 GreenVolt was awarded a Contract for Difference (CfD) by the UK Government for 400MW. This award will allow the development of the project, which is poised to become the first commercial-scale floating windfarm in Europe.

Upstream operations via Ithaca Energy
Eni is committed to contributing to the UK’s energy security and independence via its O&G activities, providing those homegrown supplies the UK needs as it transitions to net zero. In October 2024, Eni UK finalised a business combination with Ithaca Energy for its upstream portfolio, which positions the enlarged group among the main O&G producers in the country.
Accelerating the commercialisation of Fusion Energy
Eni sees strong alignment on fusion energy with the UK Authorities. We are very proud of our ongoing collaboration with the UK Atomic Energy Authority (UKAEA), with whom in March 2025 we announced a new partnership to build the world's largest and most advanced tritium fuel cycle facility to accelerate the industrialisation of fusion energy, the UKAEA-Eni H3AT Tritium Loop Facility.
