Milford Haven CO2 Project: Supporting South Wales’ low-carbon future
Milford Haven CO2 Project is a multi-partner ambition to use existing local expertise to capture, liquify, ship, and safely store, carbon emitted by operations at Pembroke Power Station.
Our Vision
Milford Haven CO2 Project brings together partners on either side of the Milford Haven – RWE and Dragon LNG. Together, working with Acorn, the partnership aims to deliver a carbon capture and storage (CCS) solution in Pembrokeshire with the potential to capture and safely store up to 5 million tonnes of CO2 per year.

Milford Haven has a long history of power generation, with The Milford Haven Waterway Future Energy Cluster, currently supplying 20% of the UK’s annual energy demand. To maintain this industry in a net zero world, RWE and Dragon LNG have come together with the ambition to use its existing expertise and strategic locations to reduce local carbon emissions and support the Welsh and UK Government’s commitment to achieve net zero power generation by 2035.
Pembroke Power Station has been generating electricity since 1964, first as an oil-fired power station, and then, from 2012 as a state-of-the-art combined cycle gas turbine station. Our ambitions for implementing carbon capture and storage technology, as part of the Milford Haven CO2 Project, will help to take Pembroke Power Station into the next phase of its operation.
Across the waterway is Dragon LNG’s terminal which imports Liquified Natural Gas (LNG), stores and re-gasifies it, to deliver a reliable and flexible supply of natural gas into homes and business across the UK. Dragon LNG is developing the integration of LNG regasification and CO2 liquefaction processes at its terminal in Waterston. This integration promises to reduce energy consumption, carbon intensity, and the levelised cost of CO2 export. This can support RWE’s ambitions to decarbonise Pembroke Power Station’s 2 GW supply by processing the captured CO2, before it is shipped to carbon sequestration sites in the North Sea.
By working in partnership on the Milford Haven CO2 Project, we can decarbonise the Power Station’s 2 GW supply, which currently powers over 4 million UK homes – over twice the number of homes in Wales. Together, our vision will build on Milford Haven’s historic energy heritage, safeguarding local jobs, while establishing the Milford Haven Waterway at the forefront of sustainable energy innovation.
The Process
Carbon capture and storage (CCS) is a decarbonisation technology which captures CO2 from emission sources and stores it safely, instead of releasing it into the atmosphere. A summary of the process, as part of the Milford Haven CO2 Project is as follows:
- Energy generation: Carbon dioxide (CO2) emissions are produced by RWE’s Pembroke Power Station during the combustion of natural gas for the generation of power by a Combined-Cycle Gas Turbine (CCGT) power station.
- Capture: CO2 is captured from the flue gas by RWE with a proven and already applied process, so that it is not released into the atmosphere.
- Liquefaction: CO2 will be transported via a new underground pipeline under the Milford Haven waterway to Dragon LNG’s site to be turned into a liquid, ready for shipping.
- Transportation: The liquid CO2 could be transported via ship from a jetty at Dragon LNG’s site on the Milford Haven to a suitable storage location off the coast of Scotland.
- Storage: The CO2 could be received by Acorn, part of the Scottish Cluster, a Track II CCS Project. With Acorn it will be safely stored permanently in depleted gas reservoirs underneath the seabed in the North Sea, preventing it from being released into the ocean or the atmosphere.

Non-pipeline transport for CCS
The UK Government has set out a clear ambition to achieve net zero by 2050 and the implementation of carbon capture and storage has a critical role in achieving this. In 2024, the UK Government pledged to invest up to £21.7 billion over 25 years to help establish a competitive carbon capture market, that could capture and store up to 20-30 million tonnes of CO2 annually by 2050.
The Government’s ambition to establish carbon capture utilisation and storage clusters aims to decarbonise heavy industrial processes such as the steel industry, as well as existing energy generators, by connecting them to safe, permanent, CO2 storage solutions via underground pipelines.
However, to meet the Welsh and UK climate goals, it is critical that opportunities for carbon capture and storage are available all across the UK, not just the clusters that expect to benefit from a pipeline CO2 storage solution.
With existing expertise, and the strategic co-location of the RWE and Dragon LNG, there is no better location to bring forward an integrated CO2 shipping solution in the UK than Milford Haven.
Delivery of the Milford Haven CO2 Project could be transformative in providing a proof of concept that evidences how the UK’s many industrial sites, major manufacturing hubs, and power stations could utilise non-pipeline solutions to capture and safely store CO2 effectively.
Many of these industries are under immense pressure to decarbonise their operations to avoid closure in a transitioning world. By evidencing the potential of non-pipeline CO2 transportation, Milford Haven CO2 Project could provide a future solution that would help to preserve major industries and safeguard jobs across the UK, while driving economic prosperity in our industrial heartlands.


Benefits for South Wales
