The HyNet North West project will capture carbon dioxide produced by land-based industrial plants and store it permanently and safely in depleted gas fields in the Irish Sea. Thanks to Carbon Capture and Storage of CO2 (CCS), one of the UK’s most energy-intensive manufacturing districts will become one of the world's first low-emission industrial clusters.
As one of the UK’s leading industrial decarbonisation projects, we are paving the way for a low-carbon future by reducing carbon dioxide emissions from industry and fostering economic growth in the North West of England and North Wales region. Eni, via its Liverpool Bay CCS project, will provide the backbone for the transportation and storage of CO2 as part of the HyNet cluster. In addition, Eni has launched the Bacton Thames Net Zero initiative in the southern North Sea of the United Kingdom, which will develop a new CCS project to contribute to the decarbonization of the Bacton area and the Thames estuary, while potentially also attracting CO2 from the European Union.

Project development and operation
Use of depleted gas fields
Carbon dioxide emitted by industrial plants in the North West of England and North Wales will be captured and permanently stored in depleted hydrocarbon fields in the Irish Sea. In this way, thanks to Carbon Capture and Storage (CCS) technology, the HyNet North West project will transform one of the most energy-intensive districts in the UK into one of the world's first low greenhouse gas emission manufacturing districts. Specifically, Eni UK's depleted offshore fields Hamilton, Hamilton North and Lennox will be used.
Eni leads the Transport and Storage of CO2
The Liverpool Bay CO2 Transport and Storage (T&S) infrastructure will be pivotal for the UK’s journey towards a Net Zero future, by unlocking the decarbonisation of the HyNet cluster in North West of England and North Wales. Thanks to the project, CO2 will be captured from industrial emitters in the region and injected into new and repurposed gas pipelines. The first emitters connecting to Eni's T&S infrastructure include industries involved in cement manufacturing, low-carbon hydrogen production, and energy-from-waste. The remaining T&S capacity will be filled with additional emitters to be selected by the UK Authorities.
