Before You Commit Capital: The Questions That Must Be Answered

Carbon capture and utilisation requires clarity on three foundational questions before capital deployment. First, does the CO₂ utilisation pathway provide genuine, permanent carbon benefit, or does it merely delay emission? CO₂ converted to synthetic fuels is released back to the atmosphere when the fuel is combusted — providing a circular carbon loop that reduces fossil feedstock demand but does not permanently sequester carbon. CO₂ mineralised into concrete aggregates or building materials provides permanent sequestration. The carbon accounting methodology used to value CCU credits determines whether and how much the utilisation pathway qualifies for carbon pricing support, which directly determines project economics. Second, what is the energy input required for CO₂ conversion, and what is the carbon intensity of that energy? CO₂ electroreduction to ethanol, methanol, or CO requires electrical energy at 400–700 kWh per tonne of product — powered by fossil electricity, the net carbon benefit is negative or marginal. Powered by renewable electricity at costs below USD 30/MWh, the economics approach viability but require electrolysis efficiency improvements not yet demonstrated at commercial scale. Third, what is the competitive price of the fossil-derived equivalent product, and what policy premium makes the CCU product viable at its current production cost?

The Drivers That Create Entry Windows

SAF (Sustainable Aviation Fuel) blending mandates are the most commercially significant driver for CCU — EU's ReFuelEU Aviation regulation mandates 2% SAF content in 2025, rising to 70% by 2050, with synthetic SAF (e-fuels) from CO₂ and green hydrogen meeting specific quota requirements. The synthetic SAF premium — USD 5–8 per litre versus USD 0.70 for fossil jet fuel — provides the revenue basis for CCU-to-e-fuel projects that no other application matches. LanzaTech's gas fermentation technology, converting CO₂ and industrial waste gases into ethanol and jet fuel components, has the most commercially advanced CCU pathway with a licensed plant operating at ArcelorMittal's Belgian steelworks and a partnership with Virgin Atlantic for SAF supply. The EU Emissions Trading System's carbon price (EUR 50–80/tonne CO₂) provides a policy basis for valuing CO₂ utilisation in industrial applications where the CCU product displaces fossil feedstock, improving project economics in proportion to ETS price.

The Barriers That Determine Who Can Compete

Product cost competitiveness is the primary barrier — all CCU pathways produce products at significant premium to fossil equivalents. E-methanol costs USD 800–1,200 per tonne versus USD 400/tonne for fossil methanol; e-kerosene costs USD 5–8 per litre versus USD 0.70 for Jet A-1. These premiums require either regulatory mandates, voluntary carbon pricing, or voluntary corporate sustainability commitments to bridge — none of which provides the volume certainty needed for multi-hundred-million-dollar CCU capital investments without government revenue support. Electrolysis efficiency for CO₂ conversion remains below commercial viability at most sites — CO₂ electroreduction produces mixed product streams requiring separation, and faradaic efficiency (the fraction of electrical input converted to desired product) of 60%–80% leaves substantial room for improvement before commercial energy economics are achieved. CO₂ feedstock availability and quality varies dramatically between point sources (steel, cement, waste-to-energy plants) and DAC, with point-source CO₂ being cheaper but geographically constrained and contaminated with impurities that increase conversion process complexity.

Market at a Glance

Where to Enter, Where to Watch, Where to Wait

CO₂-to-concrete mineralisation is the segment to enter now — CarbonCure Technologies' CO₂ injection into concrete mixing has demonstrated commercial viability at positive economics, with CO₂ improving concrete strength while being permanently mineralised, providing a carbon credit plus product quality improvement that makes the business case independent of carbon pricing above approximately USD 20/tonne. SAF from CCU is the high-reward segment to watch, with the EU ReFuelEU mandate creating a policy-guaranteed premium market but project scale and energy cost reduction requirements creating a 2028–2032 commercial window rather than an immediate one. Chemical feedstock CCU — replacing fossil-derived methanol, ethylene, and hydrogen in chemical manufacturing — is the segment to wait on, as the cost gap versus fossil feedstocks without aggressive carbon pricing is too large to close on current electrochemical efficiency trajectories within the forecast period.

Who Is Winning, Who Is Vulnerable, and Why

LanzaTech is winning — its gas fermentation platform, which operates at lower temperature and energy input than electrochemical CCU approaches, has demonstrated commercial operation at steelworks and is attracting airline and logistics company offtake commitments for its SAF products. CarbonCure is winning in the concrete segment with a commercially self-sustaining business model that doesn't require carbon pricing support. Twelve and Air Company — electrochemical CCU startups producing e-fuels and e-chemicals — are vulnerable, as their capital-intensive electrochemical processes require renewable electricity at prices and efficiencies not yet demonstrated at commercial scale, and their projected production costs depend on learning curve improvements that require capital deployment ahead of commercially verified performance. The venture funding cycle that supported these companies in 2020–2023 has tightened, and the path to commercial scale requires either policy revenue support or private capital at terms that reflect the technology development risk still embedded in electrochemical CCU processes.

Common Misconceptions About This Market

The most common misconception is that CCU and carbon capture and storage (CCS) are competing approaches — CCU converts CO₂ into products, CCS permanently sequesters it. They are complementary: CCU captures economic value from CO₂ utilisation while providing partial decarbonisation, and CCS provides permanent sequestration for residual CO₂ that CCU cannot economically convert. The second misconception is that CCU provides the same carbon benefit as CCS regardless of product lifetime — synthetic fuels release their CO₂ back to atmosphere on combustion timescales of days to years, while mineral carbonation in concrete provides permanent sequestration. The carbon accounting methodology applied to CCU products should reflect this temporal difference, and buyers paying carbon credit premiums for CCU-derived products should understand whether they are purchasing temporary storage or permanent removal.
