Padeswood CCS

The Padeswood carbon capture project is being developed at Heidelberg Materials’ Padeswood cement works in Flintshire, north Wales as part of the HyNet North West decarbonisation cluster. The facility is designed to capture around 800,000 tonnes of CO₂ per year from the cement kiln and combined heat and power plant, which represents about 95 % of the site’s process emissions. The captured CO₂ will be compressed and transported via an underground pipeline to offshore depleted gas fields beneath Liverpool Bay for permanent storage. Heidelberg Materials reached final investment decision (FID) in September 2025 after completing front-end engineering design with Mitsubishi Heavy Industries (MHI) and Worley, who will deliver the capture technology and EPCM services. Construction is expected to begin in late 2025 with commissioning targeted for 2029, enabling production of near-zero carbon cement under the company’s evoZero brand. The project received planning consent from Welsh authorities in April 2025, and commercial support agreements with the UK government under the industrial carbon capture policy framework as a priority for the HyNet cluster.
