MHI to Deliver Carbon Capture Facility for UK Cement Plant
Mitsubishi Heavy Industries (MHI) and Worley will deliver a full-scale carbon capture facility for Heidelberg Materials' cement works in Wales. The project marks the UK's first full-scale CCS facility in the cement sector and is expected to be operational by 2029.
Tokyo – Mitsubishi Heavy Industries (MHI), alongside Worley and Heidelberg Materials, has entered the execution phase for the Padeswood Carbon Capture and Storage (CCS) project in North Wales, United Kingdom.
The project will deploy MHI's Advanced KM CDR Process™ to capture approximately 800,000 tonnes of carbon dioxide (CO2) annually from cement production at Heidelberg Materials' Padeswood plant. This CO2 will be transported via pipeline for permanent storage in depleted gas fields under Liverpool Bay, as part of the HyNet North West cluster.
The move follows Heidelberg Materials' final investment decision (FID) in September 2025, made in collaboration with the UK Government under its CCUS cluster program. The new CCS facility is scheduled to be operational in 2029. MHI and Worley had previously completed a front-end engineering design (FEED) study in 2024. In the execution phase, MHI will provide engineering and procurement for the CO2 capture technology and associated equipment, while Worley will manage the engineering, procurement, and construction for the balance of plant.
Cement production is responsible for roughly 7–8% of global CO2 emissions. As most of these emissions stem from the calcination process, they cannot be avoided by switching to clean energy, making CCS the only viable option for fully decarbonized production. The Padeswood CCS project is expected to create approximately 50 new permanent jobs and secure over 200 existing roles, in addition to supporting up to 500 jobs during construction.
