Heidelberg Materials, in partnership with Worley and Mitsubishi Heavy Industries, is set to deliver the world’s first full‑scale carbon capture plant at Padeswood, marking a significant milestone in UK’s pursuit of near-zero cement production by 2029.
Mitsubishi Heavy Industries (MHI) and Worley have been contracted to deliver what Heidelberg Materials describes as the world’s first full‑scale carbon capture plant for cement production at the company’s Padeswood works in North Wales, a project the owner says will underpin the UK’s first near‑zero cement facility.
According to the original report, Heidelberg Materials has signed an engineering, procurement and construction management (EPCM) agreement with Worley and an equipment and technology supply arrangement with MHI that clears the way for full construction. The deal follows an earlier front‑end engineering and design (FEED) phase led by MHI. The parties say the facility will deploy MHI’s Advanced KM CDR Process™ to capture CO2 on site, compress it and deliver it by pipeline for permanent storage in depleted gas fields beneath Liverpool Bay as part of the HyNet North West cluster.
Project scale and timeline
There are differing capacity figures in early coverage. The lead account stated the plant would strip out around 80,000 tonnes of CO2 annually, while Heidelberg Materials and both partners’ statements set the design capture capacity at about 800,000 tonnes a year , a level the company says would equate to nearly all of Padeswood’s process emissions and enable fully decarbonised cement production. Industry documents and company releases state construction is to progress into its next phase before the end of 2025, with full commercial operation targeted by 2029 and potential early production of evoZero® near‑zero cement as early as 2028 under some timetables.
Strategic purpose and product
Heidelberg Materials says the captured CO2 will allow the plant to produce evoZero®, described as the world’s first carbon‑captured near‑zero cement at commercial scale. The company has highlighted the project as a significant milestone for decarbonising one of the UK’s most challenging industrial sectors; industry data and the company’s announcement indicate the plant would remove the bulk of the kiln‑process emissions that are the hardest to abate in cement manufacture.
Jobs and regional impact
According to the company, the project will secure more than 200 existing roles at Padeswood and support up to 500 construction jobs at peak. Heidelberg Materials and government statements accompanying a funding agreement report that the scheme will support local economic growth while forming a core anchor of the HyNet North West cluster, which aims to create a linked hydrogen and CCS network to establish a low‑carbon industrial region.
Roles and responsibilities
Under the EPCM contract, Worley will lead delivery of the carbon capture facility, and handle infrastructure integration and commissioning. MHI is supplying its KM CDR Process technology and completed FEED work earlier in the programme. Worley’s chief executive Chris Ashton said: “We’re proud to be working alongside Heidelberg Materials and MHI to deliver a facility that will help transform cement production and support the UK’s net zero ambitions.”
Funding and legal arrangements
Heidelberg Materials has confirmed it has reached a funding agreement with the UK government to advance the project, and external legal advisers have been reported as supporting the company through procurement and contracting milestones. The company has also secured planning permission for the Padeswood CCS facility, paperwork that public filings indicate envisages capture capacity consistent with the higher 800,000 tonnes‑per‑year figure.
Editorial context for industrial decarbonisation
For industrial decarbonisation practitioners, the Padeswood project is notable for combining large‑scale post‑combustion capture technology with integrated transport and storage within an established UK cluster. If delivered at the stated scale, it would represent a major test of long‑duration CO2 logistics, cluster governance and the commercial pathways for low‑carbon building materials. The programme also highlights common challenges for cement CCS projects: aligning FEED, EPCM and technology delivery schedules; securing long‑term transport and storage contracts; and converting capture capacity into commercially viable low‑carbon product lines.
Conflicting figures and next steps
Because early reports quoted a lower capture figure, project stakeholders and downstream buyers should note the company’s published materials and partner statements that set the capture design at around 800,000 tonnes per year. The immediate milestones to watch are the start of full construction activity, confirmed commissioning timelines and the establishment of CO2 export arrangements into the HyNet network , all of which will determine whether the plant meets the 2029 operational target and delivers the intended industrial decarbonisation outcomes.
