How does CCU technology reduce dependence on fossil feedstock imports?

CCU technology reduces dependence on fossil feedstock imports by converting industrial CO₂ emissions into carbon monoxide and syngas on-site, using renewable electricity instead of coal, oil, or natural gas as the carbon source. This approach allows heavy industries to produce the same chemical building blocks they currently import from fossil supply chains, but from their own waste gas streams. The sections below unpack which sectors benefit most, how the conversion works, and what it means for supply chain resilience and regulatory compliance.

What industrial sectors rely most heavily on fossil feedstock imports?

The sectors most dependent on fossil feedstock imports are steel, chemicals, petrochemicals, and synthetic fuel production. These industries use coal, natural gas, and oil not only as energy sources but as raw materials — carbon is a physical ingredient in their processes, not just a fuel. Disrupting that supply chain, whether through geopolitical events or price volatility, directly affects production continuity and competitiveness.

In steelmaking, coal-derived coke serves as both a reducing agent and a carbon source in blast furnace operations. Steel producers cannot simply switch fuel types without rethinking core chemistry. In the chemicals and petrochemicals sector, carbon monoxide and syngas derived from steam methane reforming are foundational inputs for products ranging from acetic acid to polycarbonates and methanol. These molecules are currently sourced almost entirely from fossil-based processes.

Synthetic fuel producers face a similar constraint. Producing e-fuels and sustainable aviation fuel (SAF) requires carbon-containing feedstocks, and without a low-carbon alternative to fossil-derived syngas, the decarbonization of aviation and maritime transport stalls. Across all these verticals, fossil feedstock dependency is structural — it is embedded in process design, supplier contracts, and capital assets built over decades.

The common thread is that these industries generate large volumes of CO₂-rich off-gases as a by-product of their operations. That CO₂ is currently treated as waste. Carbon capture and utilization changes that calculus entirely by treating those emissions as a recoverable carbon source.

How does CCU technology convert CO₂ into usable industrial feedstock?

Carbon capture and utilization technology converts CO₂ into usable feedstock by breaking the bond between carbon and oxygen atoms using energy — typically electricity — and recombining the resulting carbon with other inputs to produce carbon monoxide or syngas. The captured carbon re-enters the industrial value chain as a functional raw material rather than being stored or released into the atmosphere.

The specific mechanism depends on the conversion route. In plasma-based CCU systems, a CO₂-rich gas stream enters a reactor where high-energy plasma breaks the CO₂ molecule apart. The carbon atom is then combined with solid carbon feed material to yield carbon monoxide. In a second route, CO₂ is combined directly with biomethane inside the same reactor, producing syngas — a mixture of carbon monoxide and hydrogen — without requiring any external hydrogen input.

D-CRBN’s Plasma ARC™ platform demonstrates what this looks like at industrial scale. The reactor operates at ambient pressure, requires no rare-earth materials, and is built primarily from steel — which keeps capital costs significantly lower than competing conversion technologies. Pilot results at a European steel plant recorded an energy consumption of 1,100 kWh per tonne of CO₂ processed, which is roughly five times more efficient than conventional CO₂ conversion routes such as the reverse water-gas shift reaction.

Critically, the system can handle diluted CO₂ streams containing up to 50% nitrogen, meaning it does not require highly purified input gas. This makes it compatible with a wide range of industrial capture setups without adding costly upstream purification steps. The reactor also switches on and off rapidly, enabling it to run on intermittent renewable electricity and align operation with periods of low energy cost or surplus grid supply.

Which fossil feedstocks can CCU technology replace?

CCU technology can replace fossil-derived carbon monoxide, syngas, and coal-based reducing agents — the three most widely used fossil feedstocks in chemicals, steelmaking, and fuel production. By sourcing carbon from captured CO₂ rather than from natural gas or coal, industrial operators can produce functionally equivalent molecules without fossil inputs.

Carbon monoxide as a fossil feedstock replacement

Carbon monoxide is currently produced at industrial scale through steam methane reforming, a process that consumes natural gas and emits significant quantities of CO₂. CCU technology replaces this route by converting captured CO₂ directly into high-purity carbon monoxide using renewable electricity. The resulting electrified CO feedstock is chemically identical to its fossil-derived equivalent and slots directly into existing downstream processes — acetic acid synthesis, polycarbonate production, and direct reduction ironmaking among them.

Syngas as a fossil feedstock replacement

Syngas — a mixture of CO and hydrogen — is the foundation of methanol production, Fischer-Tropsch fuel synthesis, and a range of petrochemical processes. Conventionally, it is produced from natural gas or coal gasification. CCU-based syngas production from CO₂ and biomethane eliminates the need for fossil carbon inputs entirely. When both the CO₂ and the methane are of biogenic origin, the resulting green syngas carries a significantly lower lifecycle carbon footprint than any fossil-derived equivalent — and requires no external hydrogen supply, which further reduces cost and complexity.

In steelmaking specifically, carbon monoxide produced from recycled CO₂ can replace coal-derived coke as a reducing agent in blast furnaces. This is one of the most direct substitutions available to steel producers seeking to cut both fossil feedstock consumption and associated carbon costs.

How does on-site CCU deployment reduce supply chain exposure?

On-site CCU deployment reduces supply chain exposure by enabling industrial operators to produce carbon feedstocks directly from their own CO₂ emissions, eliminating dependence on external fossil suppliers. Instead of purchasing carbon monoxide or syngas from centralized production facilities tied to gas or coal markets, a plant generates what it needs from waste streams already present on-site.

The supply chain risk reduction operates across several dimensions. First, it removes price volatility exposure. Fossil feedstock costs fluctuate with oil and gas markets, which are sensitive to geopolitical events, production decisions by exporting nations, and currency movements. On-site CCU production costs are anchored to electricity prices — and when the system runs on renewable energy, those costs can be further stabilized or optimized by running during low-tariff periods.

Second, it eliminates logistical dependency. Imported feedstocks require transport infrastructure, long-term supply contracts, and exposure to border policy changes. A modular CCU unit installed at the point of emission produces feedstock where it is consumed, with no intermediate supply chain to disrupt.

Third, the modular and scalable nature of plasma-based CCU systems means operators can electrify feedstock production in phases, without decommissioning existing assets. D-CRBN’s systems are designed as plug-and-play additions to existing infrastructure — delivered in modular units, integrated without major plant reconstruction, and scalable from below 100,000 tonnes per year of CO up to large industrial throughput. This phased approach lowers the financial risk of transition while progressively reducing fossil feedstock exposure.

For industries that have experienced supply disruptions in recent years — whether from energy market shocks or import dependency on politically unstable regions — the case for on-site circular carbon production has moved from a sustainability preference to a strategic business decision.

What role does EU carbon regulation play in accelerating CCU adoption?

EU carbon regulation accelerates CCU adoption by making fossil feedstock use increasingly costly through the Emissions Trading System (ETS), which requires industrial operators to purchase allowances for every tonne of CO₂ they emit. As the carbon price rises and free allowances are phased out, converting CO₂ into feedstock rather than emitting it becomes a direct financial advantage — not just an environmental commitment.

For industries covered by the EU ETS — steel, chemicals, refining, and cement among them — each tonne of CO₂ that is captured and utilized rather than released reduces the number of allowances a facility must purchase. This creates a measurable cost saving that improves the economics of CCU investment. The higher the carbon price, the stronger the financial incentive to deploy carbon capture and utilization technology.

The Carbon Border Adjustment Mechanism (CBAM), which is progressively entering into force, adds a further dimension. It applies a carbon cost to imports of carbon-intensive goods from outside the EU, levelling the playing field between European producers operating under the ETS and non-EU competitors who face no equivalent carbon pricing. For European manufacturers, reducing their carbon intensity through CCU directly improves their competitive position relative to both domestic and international rivals.

Beyond pricing mechanisms, EU policy also provides direct support for CCU deployment. D-CRBN’s selection by the European Innovation Council’s EIC Accelerator Programme — chosen from over 1,000 proposals — reflects the EU’s active investment in carbon utilization as a pathway to industrial net-zero. Regulatory frameworks increasingly distinguish between carbon capture and storage (CCS), which sequesters CO₂ underground, and carbon capture and utilization, which converts it into products. CCU is gaining recognition as the more economically productive route for hard-to-abate industries.

For decision-makers evaluating decarbonization investments in 2026, the regulatory trajectory is clear: carbon costs will continue to rise, free allowances will continue to shrink, and the financial case for CO₂ recycling technology will strengthen accordingly. Industrial operators that deploy CCU now lock in both the compliance benefit and the supply chain advantage before market conditions tighten further.
