Carbon Capture, Utilisation and Storage: The Race to Build Industrial Decarbonisation Infrastructure at Scale

Carbon capture, utilisation and storage has moved from demonstration-stage technology into early commercial deployment across a range of industrial applications, with the convergence of carbon pricing mechanisms, government capital support programmes, and industrial decarbonisation mandates creating the investment conditions that CCUS project economics require. The technology addresses a fundamental challenge in deep decarbonisation: a substantial portion of industrial CO2 emissions from steel, cement, chemicals, and refining processes cannot be eliminated through fuel switching or electrification without fundamental process redesign, making post-combustion or process-integrated carbon capture the only near-term pathway to deep emissions reduction in these hard-to-abate sectors. The commercial infrastructure being built around CCUS, encompassing CO2 capture equipment, transport pipelines, geological storage sites, and utilisation pathways for captured carbon, represents a multi-decade infrastructure investment cycle that is attracting capital from energy majors, industrial companies, infrastructure funds, and government decarbonisation programmes simultaneously.

Industrial CCUS Applications and the Hard-to-Abate Sector Priority

Steel, cement, chemicals, and refining are the industrial sectors where CCUS deployment is most commercially advanced, as these sectors face the combination of high process emissions intensity, limited near-term alternative decarbonisation pathways, and carbon pricing exposure that makes capture and storage investment economically viable at current and projected carbon prices. Blue hydrogen production, which uses steam methane reforming with carbon capture to produce low-carbon hydrogen from natural gas, is currently the most commercially active CCUS deployment context because the hydrogen product has established market value that partially funds the carbon capture investment. Air Products, Shell, and Equinor are among the developers advancing large-scale blue hydrogen with CCUS projects in the US, UK, and Norway that are designed to serve industrial hydrogen demand from refineries, chemical plants, and emerging clean energy applications.

Cement production presents one of the most technically distinctive CCUS applications because approximately 60 percent of cement's CO2 emissions are process emissions from limestone calcination chemistry rather than fuel combustion emissions, making them impossible to eliminate through fuel switching alone. CCUS is therefore a necessary component of deep decarbonisation for the cement sector, and pilot capture installations at cement plants including Heidelberg Materials' Brevik CCS project in Norway and Holcim's Lägerdorf project in Germany are demonstrating the technical feasibility of post-combustion capture at cement kiln scale. The commercial viability of cement plant CCUS depends critically on carbon pricing levels and government capital support, as the marginal cost of carbon capture at cement plants is higher than at power generation or natural gas processing applications where CCUS has been deployed commercially for longer.

Direct Air Capture: Technology Maturation and Cost Reduction

Direct air capture, which removes CO2 directly from ambient air rather than from concentrated industrial emission streams, has advanced from academic concept to commercial operation over the past five years with the opening of Climeworks' Orca and Mammoth plants in Iceland and 1PointFive's Stratos plant in Texas representing genuine commercial DAC deployments rather than pilots. The fundamental challenge of DAC is the low concentration of CO2 in ambient air, approximately 420 parts per million, which requires processing enormous volumes of air to capture economically meaningful quantities of CO2 and results in energy requirements and cost per tonne that are substantially higher than point-source industrial capture. Current DAC costs of $400 to $1000 per tonne of CO2 captured compare unfavourably with point-source industrial capture costs of $50 to $150 per tonne, but the DAC cost reduction trajectory as technology matures and production scales is a central assumption in the investment cases that government DAC procurement programmes and corporate carbon removal purchase agreements are built on.

Government support for DAC in the US, through the Department of Energy's Regional DAC Hubs programme and the 45Q enhanced tax credit that provides $180 per tonne of CO2 sequestered through DAC, is providing the revenue certainty that early commercial DAC projects require to attract project financing. The 45Q credit effectively bridges the gap between current DAC costs and the revenue available from voluntary carbon markets for DAC removal credits, enabling DAC projects to proceed at current costs while the technology matures toward cost parity with the carbon prices that long-term DAC deployment requires. Corporate advance purchase agreements for DAC carbon removal, from companies including Microsoft, Google, Stripe, and Shopify through the Frontier programme and bilateral agreements, are providing additional demand-side certainty that complements government support in making early DAC commercial projects financeable.

CO2 Transport and Storage Infrastructure

CO2 transport pipeline networks and geological storage sites are the shared infrastructure layer that determines whether industrial CCUS can achieve the cost economics required for widespread adoption. Individual industrial facilities capturing CO2 face prohibitive costs if each project must develop its own dedicated transport pipeline and storage site, making shared infrastructure development the key to unlocking CCUS at scale in industrial clusters. The Northern Lights project in Norway, the Acorn project in Scotland, and the HyNet and East Coast Cluster projects in England are examples of shared CO2 transport and storage infrastructure developments that are designed to serve multiple industrial emitters through common pipeline and storage systems, spreading infrastructure costs across a larger volume of captured CO2 and improving project economics for all participating facilities.

Geological CO2 storage site characterisation and permitting is a long-lead activity that must be advanced years before commercial injection begins, creating a development timeline constraint that is driving early investment in storage site assessment and regulatory engagement by energy companies and infrastructure developers who anticipate growing demand for verified storage capacity. The North Sea geological formations represent some of the best-characterised and most accessible CO2 storage geology in proximity to major European industrial emission sources, and the Norwegian, UK, and Danish regulatory frameworks for offshore CO2 storage are among the most developed globally, making the North Sea a natural hub for European industrial CCUS infrastructure development over the coming decade.

CO2 Utilisation Pathways and the Carbon Economy

Carbon utilisation, converting captured CO2 into valuable products rather than permanently sequestering it, represents a complementary pathway to geological storage that can improve CCUS project economics by generating product revenue alongside carbon credit value. E-fuels produced from captured CO2 and green hydrogen through the reverse water-gas shift and Fischer-Tropsch synthesis processes are the highest-volume utilisation pathway, targeting aviation fuel and shipping fuel decarbonisation applications where electrification is not feasible. The EU's ReFuelEU Aviation regulation mandating sustainable aviation fuel blending at European airports is creating regulated demand for e-fuels that is driving investment in CO2-to-e-fuel production capacity, with projects from Norsk e-Fuel, HIF Global, and Infinium targeting commercial e-fuel production at scale.

Mineralisation of CO2 into construction materials including carbonated concrete, supplementary cementitious materials, and calcium carbonate aggregates provides utilisation pathways with large potential scale given the volume of construction materials consumed globally. CarbonCure Technologies' CO2 injection into concrete mixing has achieved commercial deployment at hundreds of concrete plants globally, demonstrating that one utilisation pathway has already crossed from development into mainstream commercial adoption. The commercial value of mineralised CO2 utilisation is enhanced by the embodied carbon accounting benefits that construction projects committed to Scope 3 emissions reduction can claim for using CO2-cured or CO2-incorporated construction materials, creating a marketing and certification value layer above the direct product economics.
