Methanol from CO₂ + H₂ is the most scalable and commercially mature CO₂-to-chemicals pathway.
CO₂ can be converted into a wide range of valuable chemicals through catalytic hydrogenation, electrochemical reduction, or biological fermentation. The most commercially mature and largest-scale pathway is methanol synthesis: CO₂ + 3H₂ → CH₃OH + H₂O. Methanol is a platform chemical with direct use as a fuel, fuel additive, and marine fuel, and as a feedstock for formaldehyde, acetic acid, dimethyl ether, and olefins. At industrial scale, methanol synthesis from CO₂ is well-established — Carbon Recycling International's George Olah plant in Iceland has been producing CO₂-derived methanol at commercial scale since 2012, using geothermal CO₂ and renewable electricity.
India's Methanol Economy Mission, launched by NITI Aayog and championed by former NITI Aayog CEO Amitabh Kant, targets 15% methanol blending in petrol (reducing oil import dependence) and the conversion of India's growing maritime sector to methanol as a marine fuel. The total methanol demand implied by these targets — approximately 12–18 MT/year by 2030 — vastly exceeds India's current methanol production capacity of approximately 2 MT/year. CO₂-derived methanol from captured industrial CO₂ and green or blue hydrogen is a natural supply source for this demand, with the additional advantage of generating carbon credits alongside the fuel value.
Beyond methanol, several other CO₂-to-chemical pathways are approaching commercial viability. Formic acid (CO₂ + H₂ → HCOOH) has applications in the leather, textile, and food industries and as a hydrogen carrier. Dimethyl carbonate (CO₂ + methanol → DMC) is a green solvent and electrolyte additive with growing demand from the lithium-ion battery sector. Polycarbonate and polyurethane production using CO₂ as a co-monomer (replacing fossil-derived phosgene or polyol segments) is being commercialised by Covestro and other companies.

Each pathway has different hydrogen requirements, capital costs, market scale, and permanence of CO₂ fixation.
The most commercially mature and largest-scale CO₂ utilisation chemistry. Iceland, China, and Germany reference plants. Drop-in fuel for petrol blending, marine fuel, and chemical feedstock. NCM's primary CO₂-to-chemicals focus for India. TRL 9.
Electrochemical or catalytic CO₂ reduction. Applications in textile, food, leather. Growing demand as a hydrogen carrier for fuel cell vehicles. TRL 7. Niche market but high value per tonne. Several Indian textile clusters are potential offtake markets.
Green solvent and electrolyte additive. Growing demand from India's expanding lithium-ion battery manufacturing sector (PLI scheme for advanced chemistry cells). CO₂ input in DMC synthesis partially offsets fossil carbon use. TRL 8.
Covestro's "cardyon" technology uses CO₂ as a 20% co-monomer in polyurethane production — replacing fossil-derived polyols. Reliance and other Indian polymer producers are potential licensees. Permanent CO₂ fixation in polymer chain. TRL 8–9.
CO₂ fed to photobioreactors drives algal biomass growth — producing omega-3 oils, animal feed, pigments, or biofuel feedstocks. Particularly relevant in water-rich coastal locations in Tamil Nadu, Goa, and Kerala. Not a large-scale CO₂ utilisation pathway but high value per tonne.
NITI Aayog's Methanol Economy report (2018) and the subsequent policy framework outline a vision for India to become both a large producer and consumer of methanol — reducing oil import dependence by USD 20–25 billion annually through petrol blending and marine fuel substitution. The report identified coal gasification with CCS as the primary production pathway for Indian methanol, given India's abundant coal reserves. CO₂-hydrogenation methanol (using captured CO₂ and green hydrogen) was identified as a complementary longer-term pathway as green hydrogen costs fall.
The coal gasification + CCS pathway for methanol production is directly within NCM's pre-combustion capture advisory scope. Producing methanol from coal gasification with CO₂ capture simultaneously produces methanol as a product, captures the CO₂ from the gasification process, and generates blue hydrogen as an intermediate — making it a triple-benefit project: methanol economy contribution, CCUS deployment, and blue hydrogen production. NCM is developing the project framework for India's first coal gasification + CCS + methanol production facility, targeted at one of the coal-rich states with methanol blending mandates: Andhra Pradesh, Assam, or Jharkhand.
The green methanol pathway — CO₂ + green hydrogen from solar-powered electrolysis — is approaching commercial viability in India's renewable energy-rich states. At solar electricity costs below USD 0.02/kWh (already achieved in Rajasthan) and green hydrogen below USD 2.5/kg (projected by 2028–2030 in India), the cost of green methanol approaches USD 350–450/tonne — competitive with or below conventional methanol market prices when carbon credit revenue is included. NCM is developing the commercial structure for India's first green methanol production and export facility in the Mundra-Kandla corridor.
NCM's CO₂-to-chemicals advisory begins with a market demand analysis — quantifying the size, price, and offtake accessibility of each target chemical market for the client's specific location, CO₂ volume, and hydrogen supply profile. We do not recommend CO₂ utilisation chemistry in the abstract: we identify specific buyers, model specific price trajectories, and structure specific offtake arrangements before recommending any chemical utilisation investment.
Technology selection is the second component — evaluating the competing catalytic, electrochemical, and biological conversion technologies for each target chemical, with specific attention to India-available technology licensors, India-compatible equipment suppliers, and India-calibrated performance assumptions. For methanol synthesis, NCM evaluates Johnson Matthey, Haldor Topsoe (now Topsoe), and Lurgi process technologies against each other for the client's specific CO₂ stream composition and hydrogen supply conditions.
Commercial structuring for CO₂-to-chemicals projects in India requires navigating three revenue streams simultaneously: the chemical product offtake revenue, the carbon credit revenue (India Carbon Market or voluntary carbon market), and the CBAM compliance value where applicable. NCM designs the revenue stack for each project to maximise bankability — presenting lenders with a multi-revenue structure that reduces dependence on any single revenue stream and improves debt service coverage ratios.
