Padeswood CCS: How Heidelberg Materials' Track-2 Decision Advances Full Cement Decarbonisation

Heidelberg Materials has confirmed the Final Investment Decision (FID) for its carbon capture and storage (CCS) project at Padeswood, UK, following a funding agreement with the UK Government. The plant will become the world's first cement production facility with fully decarbonised operations when commissioning completes in 2029. Construction is scheduled to begin in 2026, building on the experience from Heidelberg Materials' Brevik CCS plant in Norway. The Padeswood facility will capture approximately 800,000 tonnes of CO₂ annually, covering nearly all site emissions. Captured carbon dioxide will be transported and stored under Liverpool Bay as part of the HyNet North West industrial decarbonisation project.

What Makes Padeswood the First Fully Decarbonised Cement Plant?

Unlike conventional Portland cement production, which emits CO₂ both from fuel combustion and the calcination of limestone, Padeswood's CCS system will capture emissions at nearly 100% efficiency across all process stages. The project is the second large-scale cement CCS deployment for Heidelberg Materials, following Brevik in Norway. While Brevik demonstrated technical feasibility, Padeswood represents a step-change in capture completeness. The captured CO₂ will be permanently stored in geological formations beneath Liverpool Bay, part of the HyNet North West infrastructure network developed to support regional industrial decarbonisation in the UK's northwest.

HyNet North West is positioned as the UK's leading industrial decarbonisation cluster. The network aims to reduce regional carbon dioxide emissions by a quarter through carbon capture from heavy industry and the production of low-carbon hydrogen for transport, industry, and heating. By creating locally produced energy, HyNet also strengthens the UK's energy security. The project integrates proven carbon capture and storage technology with infrastructure to transport and lock away greenhouse gas emissions.

How Does the Project Impact Jobs and Regional Economy?

The Padeswood CCS investment secures more than 200 existing jobs at the site and creates up to 50 new permanent roles. During construction, the project is expected to support up to 500 jobs in North Wales. This employment impact has drawn support from political leaders, including Energy Secretary Ed Miliband, who stated that carbon capture "will create 2,000 jobs in a major boost for the local economy – providing opportunity and spreading prosperity across the region" in reference to the broader HyNet programme. Metro Mayor of Liverpool City Region Steve Rotheram highlighted that "hydrogen from HyNet will enable decarbonisation of hard-to-reach sectors, including heating of homes, fuelling of industry and flexible power generation."

What Role Does evoZero Cement Play in Market Deployment?

The Padeswood project will significantly increase the availability of evoZero, described as "the world's first carbon captured net-zero cement." The material will become accessible to more customers and larger construction projects across Europe. For specifiers and contractors working on CO₂-neutral concrete projects, the scaling of evoZero production represents a critical supply-chain milestone. The product's expanded availability could support compliance with increasingly stringent embodied carbon limits in public procurement and DGNB or BREEAM certification frameworks, especially in markets where Environmental Product Declarations (EPDs) are mandatory for large-scale projects.

Which Technology Partners Are Involved?

Mitsubishi Heavy Industries (MHI) and Worley are contracted to deliver the full-scale carbon capture facility. MHI will deploy its proprietary carbon capture technology, while Worley provides engineering and project delivery services. Both companies bring experience from industrial CCS deployments globally. The technology selection reflects a shift toward proven, commercially available capture systems rather than pilot-scale approaches. For cement producers evaluating their own decarbonisation roadmaps, the Padeswood specification offers a reference benchmark for capture efficiency, capital expenditure, and operational integration.

What Are the Implications for UK and European Cement Markets?

The UK Government's funding commitment under the Track-2 cluster framework signals policy alignment with capital-intensive decarbonisation infrastructure. For cement producers across Europe, the Padeswood FID represents a test case for combining CCS investment with national subsidy mechanisms. The project's timeline—commissioning in 2029—places it ahead of the EU's Carbon Border Adjustment Mechanism (CBAM) full enforcement phase, providing a competitive advantage in markets sensitive to CBAM pricing. Heidelberg Materials' dual deployment in Norway and the UK also establishes a template for multi-site CCS rollouts, potentially informing future projects in Germany, France, and other high-production regions.

As industrial clusters such as HyNet demonstrate integrated transport and storage infrastructure, the viability of CCS for hard-to-abate sectors—cement, steel, chemicals—improves. For material specifiers, the growing availability of verified net-zero concrete and cement products will necessitate updating procurement criteria, EPD databases, and lifecycle assessment tools to reflect the carbon intensity reductions enabled by projects like Padeswood.
