For decades, carbon capture, utilisation and storage was described as a promising but perpetually horizon technology — always important in net zero scenarios yet always a decade away from commercial scale. That characterisation is rapidly becoming outdated. Today, CCUS is moving from pilot projects and demonstration facilities into full-scale industrial deployment, driven by tightening carbon regulations, improving economics and the recognition that hard-to-abate industrial sectors cannot decarbonise through fuel switching alone. For the oil and gas industry in particular, CCUS represents both a critical decarbonisation tool and, for some operators, a viable new business line.
What CCUS is and How It Works
Carbon capture, utilisation and storage encompasses a family of technologies designed to prevent carbon dioxide from entering the atmosphere. In a typical capture application, CO2 is separated from flue gas or process streams at industrial facilities using chemical solvents, physical sorbents or membrane systems. The captured CO2 is then compressed, transported by pipeline or ship, and either stored permanently in deep geological formations — typically depleted hydrocarbon reservoirs or deep saline aquifers — or utilised in industrial processes such as enhanced oil recovery, cement production, synthetic fuel manufacture or mineralisation. The distinction between storage and utilisation is important: storage achieves permanent CO2 removal, while utilisation may defer or reduce but not always eliminate eventual atmospheric release.
Point-source capture from high-concentration streams — such as natural gas processing, hydrogen production or ammonia manufacture — is currently the most cost-competitive CCUS application. Post-combustion capture from power stations and industrial boilers is technically proven but more expensive due to the lower CO2 concentration in dilute flue gases. Direct air capture, which extracts CO2 directly from ambient air, offers flexibility in siting but currently carries very high costs — typically in excess of $300 per tonne of CO2 — making it largely reliant on public subsidy or premium carbon credit prices. However, costs are declining as the technology matures and scale increases.
Current Deployment and Scale
Global CCUS capacity has grown meaningfully in recent years, though it remains far below the scale required to meet net zero scenarios. The International Energy Agency estimates that reaching net zero emissions by 2050 requires capturing and storing approximately 1.7 billion tonnes of CO2 per year by mid-century — compared to roughly 50 million tonnes per year currently captured worldwide. Major operational projects include the Sleipner CO2 storage site in Norway, the Quest facility in Canada, the Boundary Dam project in Saskatchewan and the Abu Dhabi CCUS project in the UAE. Planned mega-projects in the UK's East Coast Cluster, the Northern Lights shipping and storage infrastructure in Norway and multiple US Gulf Coast industrial hubs signal a significant acceleration in capital deployment.
Government support has been a critical enabler of this expansion. The US Inflation Reduction Act significantly enhanced the 45Q tax credit for carbon capture and storage, making US CCUS projects materially more attractive to private capital. The UK has committed funding to two CCUS industrial clusters as anchor investments in its net zero strategy. The European Union's Innovation Fund supports CCUS alongside other clean technologies. These policy signals have shifted the investment calculus for project developers and lenders, unlocking capital that had previously been unwilling to take unhedged exposure to nascent carbon abatement markets.
As investment accelerates, organisations must also prioritise workforce readiness to manage increasingly complex CCUS systems. Building expertise in operational safety, environmental compliance and risk mitigation is essential, and many professionals are turning to advanced Health, Safety & Environment Training Courses for carbon capture operations and industrial sustainability to strengthen their capabilities in this evolving landscape.
CCUS in Oil and Gas Operations
For the oil and gas sector, CCUS is relevant at multiple points across the value chain. Upstream operators can capture CO2 from gas processing facilities and inject it into geological storage or use it for enhanced oil recovery. LNG liquefaction plants, which generate significant process emissions, are increasingly evaluating integrated CCS solutions to reduce their carbon footprint and maintain access to environmentally conscious buyers. Midstream operators can repurpose existing pipeline infrastructure for CO2 transport, potentially unlocking a new revenue stream from third-party CO2 shippers. Refineries and petrochemical facilities represent high-volume point-source emission sites where post-combustion or process capture can yield significant tonne-per-year abatement volumes.
Some major international oil companies have positioned CCUS as a core element of their energy transition strategy, establishing dedicated business units to develop, operate and commercialise storage capacity. This reflects a recognition that the geological expertise, subsurface characterisation skills and reservoir management competencies accumulated over decades of hydrocarbon production are directly transferable to CO2 storage operations. For upstream professionals, this creates a compelling opportunity to apply existing skills in a decarbonised context — a factor increasingly relevant to workforce retention and talent attraction in a sector facing reputational headwinds.
Challenges and the Path to Scale
Despite growing momentum, CCUS faces significant headwinds. The economics of many projects remain challenging outside regions with strong government support, particularly where CO2 pricing mechanisms are absent or weak. Public acceptance — particularly around geological storage and CO2 pipeline routing — has delayed projects in multiple jurisdictions. Monitoring, reporting and verification requirements for storage sites add cost and complexity. The long-term liability for stored CO2 — who is responsible if CO2 leaks from a storage formation after a project operator has ceased operations — remains an unresolved legal and regulatory question in many countries.
Scale-up also requires a step-change in CO2 transport and storage infrastructure. The development of shared, open-access pipeline networks and storage hubs — on the model of the North Sea's Northern Lights project — is essential to reducing costs through economies of scale and avoiding the duplication of infrastructure. Industry collaboration, underpinned by clear regulatory frameworks and equitable cost-sharing mechanisms, will determine the pace at which CCUS transitions from a collection of individual projects into a mature, functioning industrial system capable of delivering meaningful climate impact.
Alongside infrastructure and policy development, strengthening human capital remains a critical enabler of scale. Organisations that invest in specialised Health, Safety & Environment Training Courses for CCUS risk management and environmental protection will be better equipped to ensure safe operations, regulatory compliance and long-term project success.
Conclusion
CCUS has moved decisively from aspiration to action. While the gap between current deployment and the scale required for net zero remains substantial, the trajectory is encouraging. For oil and gas professionals, understanding CCUS technology, economics and project development is increasingly a core competency — whether in engineering, commercial, regulatory or strategic roles. The sector's future competitive positioning will in part be defined by the depth and quality of expertise it brings to bear on this critical challenge.
