Carbon capture utilisation (CCU) is generally more cost-effective than carbon capture and storage (CCS) for industrial operators because it generates revenue from the captured COâ‚‚ rather than treating it as a waste stream requiring permanent disposal. Where CCS demands ongoing expenditure with no return, CCU converts COâ‚‚ into sellable feedstocks such as carbon monoxide and syngas, creating a business case that offsets or exceeds the cost of the technology itself. The sections below examine each dimension of this cost comparison in detail, from infrastructure burdens and revenue potential to regulatory exposure and long-term financial risk.

What are the main cost drivers behind CCS infrastructure?

The main cost drivers behind carbon capture and storage infrastructure are geological site assessment and permitting, COâ‚‚ compression and transport pipelines, long-term monitoring obligations, and permanent liability for stored carbon. These components combine to make CCS a capital-intensive commitment with no commercial return: every euro spent is a sunk cost against a regulatory obligation, not an investment in productive output.

Geological storage requires extensive site characterisation before a single tonne of COâ‚‚ is injected underground. Operators must demonstrate that the formation is stable, impermeable, and capable of holding COâ‚‚ indefinitely. This process involves seismic surveys, test drilling, and regulatory approval cycles that can span years. Once approved, the site requires a dedicated pipeline network to transport compressed COâ‚‚ from the industrial source to the injection point, infrastructure that typically serves no other commercial purpose.

Compression is a significant ongoing energy cost. COâ‚‚ must be pressurised to supercritical conditions for pipeline transport and injection, which demands continuous power input. Unlike CCU processes that can be optimised around renewable energy availability, CCS compression must run continuously to maintain pipeline pressure, making it difficult to benefit from low-cost intermittent electricity.

Post-injection monitoring adds another layer of cost that extends decades beyond the operational phase. Regulations in most jurisdictions require operators to verify containment integrity long after injection has ceased, creating financial liabilities that persist on balance sheets indefinitely. For industrial decision-makers evaluating total cost of ownership, this tail liability is a material consideration that rarely features prominently in headline cost comparisons.

How does CCU generate revenue where CCS cannot?

Carbon capture utilisation generates revenue by converting captured COâ‚‚ into marketable industrial feedstocks, primarily carbon monoxide and syngas, that replace fossil-derived inputs in chemical, steel, and fuel production. Instead of paying to dispose of COâ‚‚, operators sell or consume the conversion output, turning a compliance cost into a productive asset within the existing value chain.

The revenue logic is straightforward. Carbon monoxide is a critical building block for chemicals including acetic acid and polycarbonates, and for iron ore reduction in steelmaking. Syngas serves as a precursor for synthetic fuels and a wide range of chemical processes. Both products currently derive predominantly from fossil feedstocks, meaning CCU-produced alternatives compete in established, liquid markets with clear pricing benchmarks.

For operators who consume CO or syngas internally, CCU replaces a procurement cost rather than generating an invoice, the financial benefit is equivalent but appears on the cost side of the ledger. For those who produce more than they consume, the surplus can be sold externally. Either way, the economics are structurally different from CCS: the technology pays for itself through output value rather than through avoided penalties alone.

D-CRBN’s plasma conversion technology illustrates this model in practice. By using renewable electricity to split COâ‚‚ into carbon monoxide at an energy consumption of around 1,100 kWh per tonne of COâ‚‚, the process produces feedstock at a cost that competes directly with fossil-based CO production, meaning the revenue case holds even without a carbon price premium. This is a meaningful distinction: the business case does not depend on sustainability premiums that markets are increasingly unwilling to pay.

Which industries benefit most from CCU over CCS?

The industries that benefit most from CCU over CCS are those that both generate large volumes of COâ‚‚-rich off-gases and consume carbon-based feedstocks internally: steel producers, chemical and petrochemical companies, synthetic fuel producers, and biogas operators. For these sectors, CCU closes a loop that already exists within their operations, making integration commercially and logistically straightforward.

Steel and metals production

Steel producers operating blast furnaces emit COâ‚‚-rich process gases continuously and simultaneously consume carbon monoxide as a reducing agent for iron ore. CCU allows captured blast furnace off-gases to be converted back into CO, which re-enters the reduction process, replacing coke-derived CO and reducing both fossil dependency and ETS liability. The first industrial trial of D-CRBN’s electrified CO production took place at a major European steel plant, where the technology demonstrated safe operation and record-low electricity consumption at an active major-hazard industrial site.

Chemical and petrochemical production

Chemical producers require CO and syngas as base inputs for a wide range of downstream products. CCU allows these companies to source feedstock from their own captured emissions rather than purchasing fossil-derived CO from external suppliers. The supply chain benefit is twofold: lower procurement exposure to fossil feedstock price volatility and a reduced Scope 3 emissions profile, which is increasingly relevant under tightening supply chain due diligence regulations.

Biogas and wastewater operators

Biogas producers and wastewater treatment operators generate methane-rich streams that can be combined with COâ‚‚ in a plasma reactor to produce green syngas without requiring external hydrogen. This route is particularly attractive because the carbon in both feedstreams is biogenic, enabling a genuinely carbon-negative output on a life-cycle basis. D-CRBN’s electrified syngas production covers exactly this pathway, with a pilot launched in 2026 converting wastewater biogas into green methanol through a full value-chain integration.

How do ETS carbon pricing and regulations affect the CCU vs CCS decision?

EU Emissions Trading System pricing strengthens the financial case for CCU over CCS by making COâ‚‚ emissions directly costly, increasing the value of avoided emissions, and simultaneously rewarding the production of low-carbon feedstocks that displace fossil inputs. As ETS carbon prices rise, the avoided-cost benefit of CCU compounds: operators avoid paying for the COâ‚‚ they convert, and their customers face lower Scope 3 liabilities when they purchase CCU-derived feedstocks instead of fossil-based alternatives.

CCS also benefits from ETS in theory: stored COâ‚‚ avoids the carbon price. However, CCS offers no product revenue, so the financial return is capped at the carbon price multiplied by the tonnes stored. CCU, by contrast, generates both the avoided-cost benefit and the product revenue, making its total return structurally superior at any given carbon price level.

Regulatory direction also matters. The EU’s carbon border adjustment mechanism and evolving supply chain sustainability requirements are increasing pressure on industrial buyers to demonstrate low-carbon feedstock sourcing. CCU-derived CO and syngas carry a substantially lower carbon footprint than fossil-derived equivalents: life-cycle assessments indicate that using renewable electricity and biogenic COâ‚‚ can achieve a carbon-negative output compared to the roughly 2.1 tonnes of COâ‚‚-equivalent emitted per tonne of CO produced through conventional fossil routes. This positions CCU output as a premium-free, compliance-compatible alternative that aligns with where regulation is heading.

What are the long-term cost risks of carbon capture and storage?

The long-term cost risks of carbon capture and storage include geological leakage liability, regulatory reclassification of stored COâ‚‚, stranded asset exposure if storage sites are decommissioned, and the absence of any mechanism to recover sunk costs through future revenue. These risks are not hypothetical: they reflect the structural reality that CCS creates permanent obligations without creating permanent value.

Geological containment is not guaranteed over century-scale timeframes. If stored COâ‚‚ migrates or leaks, the operator may face re-emission penalties under whatever carbon pricing regime is in force at the time of leakage, potentially far higher than today’s ETS price. This creates an open-ended financial liability that is difficult to model and impossible to hedge through conventional insurance products.

Regulatory risk compounds the geological risk. Carbon storage regulations are still maturing in most jurisdictions, and the long-term liability transfer frameworks, which determine when and whether the state assumes responsibility for stored COâ‚‚, vary significantly across markets. Operators who invest in CCS today may find that liability transfer conditions change before they qualify, leaving them holding permanent obligations on assets that have ceased to generate any operational value.

By contrast, CCU assets depreciate like conventional industrial equipment. The reactor, the integration infrastructure, and the operational know-how all retain value or can be redeployed. There is no tail liability, no geological monitoring obligation, and no exposure to future regulatory reclassification of the stored material. For CFOs and sustainability directors evaluating long-term balance sheet risk, this distinction is increasingly decisive.

Is CCU cost-effective enough to compete with fossil feedstocks today?

Yes, CCU is cost-effective enough to compete with fossil feedstocks today, provided the technology is sufficiently energy-efficient. Energy cost is the primary variable that determines whether CCU-derived CO or syngas can match fossil-based production on price, and the most advanced plasma-based systems have now reached efficiency levels that make price parity achievable without relying on carbon price support or sustainability premiums.

The critical threshold is energy consumption per tonne of output. Conventional CO production routes carry both fuel costs and significant carbon liabilities. A CCU process powered by renewable electricity eliminates the carbon liability and replaces the fuel cost with an electricity cost, but only competes on total cost if the electricity consumption per unit of output is low enough. At around 1,100 kWh per tonne of COâ‚‚ processed, D-CRBN’s plasma platform operates at roughly five times the energy efficiency of competing conversion routes, which is what makes the economics viable at current industrial electricity prices.

The plug-and-play deployment model also reduces the capital barrier to entry. D-CRBN’s modular reactor systems arrive containerised, integrate directly into existing infrastructure, and require no write-offs of existing plant assets. This lowers the upfront investment threshold compared to greenfield CCS projects and allows operators to scale incrementally, starting with a smaller unit and expanding as output volumes and economics are validated on site.

For industrial operators currently purchasing fossil-derived CO or syngas from external suppliers, the comparison is direct: CCU-derived feedstock from on-site plasma conversion versus market-priced fossil CO. As fossil feedstock prices remain exposed to geopolitical volatility and import dependency, the stability of an on-site, electricity-powered production system carries additional value beyond the unit cost comparison. Operators who want to explore what this looks like for their specific site can design a tailored electrified feedstock solution with D-CRBN’s engineering team.

In short, CCU is not a future promise contingent on favourable policy. For energy-intensive industries generating COâ‚‚-rich off-gases, it is a commercially viable alternative to both fossil feedstock procurement and carbon storage, one that improves with every incremental rise in ETS prices and every reduction in renewable electricity costs. To understand how COâ‚‚ recycling fits your operations, the conversation is worth starting now.
