Using COâ‚‚ as a feedstock is more valuable than carbon sequestration because it converts a waste gas into a revenue-generating industrial input rather than burying it indefinitely underground. Instead of paying to store carbon, industrial operators can recycle COâ‚‚ into carbon monoxide or syngas and sell or use those outputs as drop-in replacements for fossil-derived feedstocks. The sections below unpack the economics, the chemistry, the regulatory picture, and which industries stand to gain the most.

What are the main drawbacks of carbon sequestration?

Carbon sequestration, specifically carbon capture and storage (CCS), permanently removes COâ‚‚ from industrial processes by compressing it and injecting it deep underground. While it reduces atmospheric emissions, it treats COâ‚‚ purely as a liability, a problem to be buried rather than a resource to be used. The core drawbacks are structural and economic, not incidental.

• Permanent cost with no return: CCS requires continuous energy input for compression, transportation, and injection. Operators pay to dispose of COâ‚‚ and receive nothing back. Over time, this becomes a significant and unavoidable operational cost.
• Infrastructure dependency: Geological storage requires proximity to suitable formations or access to COâ‚‚ pipelines. Most industrial sites are not located near viable storage sites, making CCS logistically complex and capital-intensive.
• Long-term liability: Stored COâ‚‚ must be monitored for leakage over decades. Regulatory frameworks for long-term geological liability are still evolving, leaving operators exposed to future compliance risk.
• No feedstock independence: CCS does nothing to reduce dependence on fossil-derived raw materials. A steel plant or chemical producer that captures and stores its COâ‚‚ still needs to purchase fossil feedstocks separately, the circular loop remains broken.
• Energy penalty: Capture, compression, and injection consume substantial energy, reducing the net efficiency of the industrial process without generating any productive output.

For industries under pressure to both decarbonize and remain cost-competitive, CCS addresses only the emissions side of the equation while adding cost and complexity. Carbon capture and utilization (CCU) approaches offer a fundamentally different logic: the captured carbon becomes an asset.

How does CO2 utilization turn a liability into a revenue stream?

COâ‚‚ utilization converts captured carbon dioxide directly into marketable industrial feedstocks, primarily carbon monoxide (CO) and syngas, which replace fossil-derived inputs in existing production processes. Rather than spending money to dispose of COâ‚‚, industrial operators can use it as a raw material, generating outputs that have real market value and reducing the need to purchase fossil feedstocks.

The economic logic is straightforward. Carbon monoxide is a critical building block for chemicals including acetic acid and polycarbonates. Syngas is the precursor to synthetic fuels, methanol, and a wide range of chemical intermediates. Both are currently produced from fossil sources at significant cost and with significant emissions. When COâ‚‚-derived CO or syngas can be produced at a competitive price point, the industrial operator gains on two fronts: lower feedstock procurement costs and a reduced COâ‚‚ footprint that translates directly into lower exposure to EU Emissions Trading System (ETS) costs.

There is also a supply chain dimension. Fossil feedstock prices fluctuate with geopolitical events and commodity markets. COâ‚‚, by contrast, is generated on-site as a byproduct of existing operations, it is a captive, stable, and effectively free raw material. Converting that internal waste stream into usable feedstock gives operators price predictability and supply resilience that fossil sourcing cannot match.

Technologies like D-CRBN’s Plasma ARCâ„¢ platform make this conversion commercially viable by achieving the energy efficiency required to compete with fossil-derived alternatives. The system uses renewable electricity to break COâ‚‚ into CO without producing byproducts, and the modular design means it can be deployed as an add-on to existing infrastructure, no plant redesign, no write-offs.

What products can be made from recycled CO2?

Recycled COâ‚‚ can be converted into carbon monoxide (CO) and syngas, two foundational industrial feedstocks that serve as entry points into a wide range of downstream products. These include synthetic fuels, methanol, acetic acid, polycarbonates, polymers, and iron ore reducing agents used in steelmaking.

Carbon monoxide as a chemical building block

Carbon monoxide is a core intermediate in base chemistry. It is used in the production of acetic acid, polycarbonates, and a range of other chemicals that are currently sourced from fossil-based CO. When produced from COâ‚‚ via electrified CO production, it functions as a direct drop-in replacement, requiring no modification to downstream processes. In steelmaking, CO can also serve as an iron ore reducing agent in blast furnaces, partially replacing coke and reducing the carbon intensity of the process.

Syngas as a precursor to fuels and chemicals

Syngas, a mixture of CO and hydrogen, is the starting point for synthetic fuels (e-fuels), methanol, and ammonia. Produced from COâ‚‚ and methane through plasma conversion, it enables the manufacture of these products without fossil inputs or the need for separately produced green hydrogen. Electrified syngas production from COâ‚‚ and methane is already being demonstrated in a wastewater-to-methanol value chain, where biogas from sludge digestion is converted into green syngas and subsequently into green methanol for chemical production.

The breadth of downstream applications means that COâ‚‚ recycling does not require the construction of entirely new value chains. The outputs slot into existing industrial infrastructure, which is precisely what makes the transition commercially attractive for operators who cannot afford to redesign their production assets from scratch.

Which industries benefit most from CO2 feedstock conversion?

The industries that benefit most from COâ‚‚ feedstock conversion are those that simultaneously generate large volumes of COâ‚‚-rich off-gases and consume significant quantities of carbon-based feedstocks. Steel production, chemicals and petrochemicals, synthetic fuel manufacturing, and biogas operators are the primary beneficiaries.

• Steel producers: Blast furnaces emit COâ‚‚-rich process gases continuously. Converting that COâ‚‚ back into carbon monoxide creates an on-site reducing agent that can replace coke in the ironmaking process, reducing both emissions and fossil input costs. The first industrial trial of plasma-based COâ‚‚ conversion took place at a major European steel plant, validating the approach at real-world scale.
• Chemical and petrochemical companies: These operators are large consumers of carbon monoxide and syngas as feedstocks for acetic acid, polycarbonates, methanol, and other intermediates. Replacing fossil-derived CO with COâ‚‚-recycled CO reduces their ETS exposure and improves supply security.
• Synthetic fuel and e-fuel producers: Syngas is the gateway molecule for e-fuels. Producers seeking to manufacture sustainable aviation fuel or synthetic diesel without relying on fossil inputs or separately produced hydrogen can use COâ‚‚ and methane as feedstocks through plasma conversion.
• Biogas and wastewater operators: Sites that produce biogas from organic waste streams can convert that biogas directly into green syngas, creating a circular value chain from waste to chemical feedstock. This unlocks revenue from a byproduct that would otherwise be flared or used only for low-value heat generation.

Across all these sectors, the common thread is that COâ‚‚ feedstock conversion works best where carbon is already being captured or where off-gas volumes are large enough to justify on-site deployment. The modular, plug-and-play nature of systems like D-CRBN’s means that even distributed industrial sites can access this capability without major infrastructure investment.

How does CO2 feedstock utilization compare to CCS on cost and energy?

COâ‚‚ feedstock utilization is more cost-effective than CCS for most industrial operators because it generates a marketable output that offsets the cost of conversion, whereas CCS generates no return on the energy and capital invested. The net economics favor utilization wherever the converted feedstock can compete on price with its fossil equivalent.

On the energy side, the critical factor is conversion efficiency. Conventional COâ‚‚ conversion routes such as the reverse water-gas shift reaction are energy-intensive, which historically made COâ‚‚-derived feedstocks uncompetitive. Plasma-based conversion changes this equation. D-CRBN’s process requires approximately 1,100 kWh per tonne of COâ‚‚ processed, a figure that is roughly five times more energy-efficient than competing conversion technologies. At that efficiency level, and when powered by renewable electricity, the cost of producing CO or syngas from COâ‚‚ can be competitive with fossil-derived alternatives, particularly when ETS carbon costs are factored in.

CCS, by contrast, imposes an energy penalty without generating any productive output. The compression and injection of COâ‚‚ consumes energy, increases operational costs, and provides no feedstock value. For an industrial operator running tight margins, CCS is a cost center. COâ‚‚ utilization, done efficiently, can be a profit center.

There is also a capital expenditure dimension. D-CRBN’s plasma systems carry a CAPEX that is approximately 50% lower than second-generation reverse water-gas shift technology, with the primary material being steel. Combined with modular deployment, meaning operators can start small and scale incrementally, the financial risk profile of CCU is substantially lower than building dedicated CCS infrastructure.

Lifecycle assessment data reinforces the environmental case. Conventional fossil-based CO production generates roughly 2.1 tonnes of COâ‚‚-equivalent per tonne of CO produced. Using renewable electricity and biogenic COâ‚‚ as feedstock, plasma-based conversion can achieve a carbon-negative outcome, delivering genuine emissions reduction rather than simply relocating the problem underground.

Does CO2 feedstock utilization qualify under EU carbon regulations?

Yes, COâ‚‚ feedstock utilization qualifies under EU carbon regulations, and in several respects it is better positioned than CCS. Under the EU Emissions Trading System, industrial operators pay for each tonne of COâ‚‚ they emit. Converting COâ‚‚ into a feedstock rather than venting it reduces the volume of emissions that attract a cost, directly improving the operator’s ETS position.

The EU’s regulatory framework increasingly recognizes Carbon Capture and Utilization as a legitimate decarbonization pathway. The European Commission’s industrial strategy and the Net-Zero Industry Act explicitly support CCU technologies as part of the clean technology manufacturing ecosystem. D-CRBN itself received a €2.5 million grant from the European Innovation Council’s EIC Accelerator Program, selected from over 1,000 proposals, which reflects the EU’s institutional recognition of COâ‚‚ recycling as a priority technology.

For operators producing e-fuels or synthetic chemicals from recycled COâ‚‚, there are additional regulatory benefits. The EU’s Renewable Energy Directive (RED III) and the ReFuelEU Aviation regulation create demand for sustainable fuels with verified low-carbon feedstock chains. Syngas and CO derived from captured industrial COâ‚‚ and renewable electricity can qualify as inputs into these certified supply chains, opening access to premium markets and compliance credits.

The key regulatory advantage of utilization over storage is permanence of benefit. CCS removes COâ‚‚ temporarily, the storage must be maintained and monitored indefinitely. Utilization locks carbon into products, and when those products replace fossil-derived alternatives, the net emissions reduction is real and verifiable across the supply chain. For sustainability directors and procurement officers navigating scope 1, 2, and 3 reporting obligations, this traceability is a meaningful advantage.

Industrial operators ready to explore how electrified COâ‚‚ conversion fits their operations can discuss feedstock electrification directly with D-CRBN, or review the full range of deployment options with the team to identify the right scale and integration pathway for their site.
