UK’s carbon removal pilots highlight progress and urgent policy needs to unlock commercialisation

The UK government’s Phase Two reports from the Direct Air Capture and Greenhouse Gas Removal Innovation Programme confirm that a broad portfolio of pilot and demonstration projects has moved several carbon removal approaches beyond the laboratory, but that cost, energy intensity and questions over scalability remain stubborn barriers to commercial deployment. According to Energy News, more than a dozen pilots led by industry, startups and research consortia have produced “early but instructive” results that map technical progress while exposing persistent economic and operational constraints.

Direct air capture (DAC) continues to be a dominant focus. Projects such as Cambridge Carbon Capture’s Direct Air CO2 Capture and Mineralisation trial and the Smart-DAC sorbent work have demonstrated alternative capture chemistries and modular approaches intended to lock CO2 into stable mineral forms or reduce energy use. Equinor’s ENCORE Phase Two explored liquid-based capture chemistry operating at lower temperatures. The programme’s developers reported technical advances, but the broader literature underscores the scale of the challenge: direct air capture remains energy intensive and costly, with independent sources noting system costs that, in current deployments, are significantly higher than established abatement routes. Industry data and academic summaries show DAC cost ranges and uncertainties that still make DAC hard to reconcile with near-term industrial budgets.

Bioenergy-linked approaches delivered mixed outcomes. Evero’s Ince facility within the HyNet cluster and the CCH2 project tested co-location of biomass gasification, hydrogen production and capture processes, illustrating how greenhouse gas removal might be embedded in regional industrial clusters. These demonstrations point to potential synergies , for example, shared heat and feedstock logistics , but also expose integration risks, rising capital costs and operational complexity that keep unit costs high compared with conventional energy or abatement investments.

The programme deliberately included unconventional pathways. SeaCURE examined enhanced ocean alkalinity as a route to increase CO2 uptake in seawater, and the Reverse Coal project looked at engineered burial of carbon-rich char. The GreenShed initiative broadened the remit to methane reduction and capture in livestock systems, signalling a pragmatic recognition that the UK’s removal portfolio must be diverse to address residual emissions from sectors such as aviation and agriculture. The Climate Change Committee has emphasised the necessity of removals for offsetting residual emissions, a position reflected in the programme’s funding priorities.

Public policy context raises a note of caution. The UK established the CCUS Cost Challenge Taskforce in 2018 to advise on lowering deployment costs and accelerating delivery; the taskforce’s recommendations informed the CCUS Deployment Pathway published the same year. Yet more recent analysis by Carbon Tracker, reported by S&P Global, warns that deployment cost assumptions underpinning parts of the UK CCUS strategy are “outdated and unrealistic,” that costs have more than doubled in some estimates since 2020, and that the practical size of demand for capture may be significantly smaller than earlier projections. Those findings amplify the Phase Two pilots’ central message: technological promise does not yet equate to bankable economics.

Industry groups are urging swifter policy clarity. The Carbon Capture and Storage Association’s updated delivery plan, cited by Carbon Capture Journal, argues the sector is at a “critical juncture” and that clear government decisions by 2026 will be needed to unlock private capital, protect industrial jobs and keep projects in the UK. Meanwhile, reporting by OPIS illustrates how logistical and institutional bottlenecks , for example, the need for CO2 transport pipelines and shortages of specialist civil service capacity , are already delaying cluster development despite continued political support for targets to capture 20–30 million tonnes by 2030.

Government funding has seeded the pilots: an initial £54 million committed in 2021 to stimulate innovation and attract private investment. According to the Phase Two reports summarised by Energy News, that funding has helped surface real-world data on energy consumption, plant uptime, capture efficiency and integration costs , all essential inputs for the next round of project design and commercial negotiation. Yet both public and independent assessments, including cost sensitivity work from the Climate Change Committee’s Seventh Carbon Budget, make clear that sizeable additional capital, long-term revenue models and lower operating costs are prerequisites for scaled deployment.

For businesses involved in industrial decarbonisation the implications are pragmatic. The pilot portfolio shows which technical directions merit further investment , modular DAC units, lower-temperature liquid chemistries, co-located biomass capture and combined hydrogen-carbon removal hubs , but it also signals that near-term commercialisation will require policy instruments that reduce investor risk: long-duration contracts, predictable CO2 transport and storage infrastructure, and realistic appraisal of carbon pricing and demand. As Carbon Tracker and other analysts caution, misaligned incentives risk locking capital into expensive, fossil-linked infrastructure when cheaper alternatives may be available.

The Phase Two findings therefore reinforce a two-track conclusion: continued R&D and demonstration are essential to reduce technical uncertainty and drive down costs, but parallel, concrete policy and delivery actions are required to translate pilot successes into investible projects. Industry bodies, independent analysts and government taskforces converge on the need for clearer market design and faster infrastructure decisions if the UK is to develop a competitive domestic greenhouse gas removal industry rather than a patchwork of high-cost pilots.

For decision-makers in industrial decarbonisation, the Phase Two reports offer disciplined, operationally grounded intelligence: they identify technically promising avenues and quantify the economic gaps that must be closed. Closing those gaps will determine whether the UK’s removal industry becomes a platform for green jobs and inward investment, as envisaged in policy statements, or a cautionary tale of early-stage innovation outpacing the market mechanisms needed to scale it.
