From CO₂ to Jet Fuel: How AirPlant One Works
AirPlant One is built around Twelve’s electrochemical CO₂ conversion technology, which uses renewable electricity to break carbon dioxide into the carbon monoxide building blocks for synthesis gas, which is then processed into a hydrocarbon jet fuel certified as a drop-in replacement for conventional Jet-A. The Moses Lake location is deliberate: the Columbia River basin offers some of the lowest-cost renewable electricity in the United States, making the energy-intensive Power-to-Liquid pathway more commercially viable. The resulting eSAF carries a drastically lower lifecycle carbon intensity than fossil kerosene, with no changes required to existing aircraft, engines, or fuelling infrastructure.
Why Timing and Regulation Make This Project Critical
AirPlant One’s launch arrives as regulatory demand for SAF accelerates on both sides of the Atlantic. Switzerland formally adopted ReFuelEU Aviation on 1 January 2026, meaning fuel suppliers at Zurich and Geneva airports must already meet a 2% SAF blend requirement — a figure that scales to 70% by 2050. The broader ReFuelEU framework that applies across EU member states creates a binding, growing market that eSAF producers like Twelve are positioning to serve. Commercial-scale eSAF production in North America also matters for transatlantic routes, where carriers face compounding SAF obligations as they operate under both US and European regulatory environments.
Airlines are simultaneously deploying AI-driven flight-planning tools that optimise routing and throttle profiles to cut fuel burn, compressing the volume of SAF required per revenue tonne-kilometre and improving the economics of blending premium-priced eSAF into the fuel pool. That convergence of operational efficiency and low-carbon supply is where decarbonisation commitments become financially sustainable.
Industrial Scale and the Road Ahead for eSAF
The global SAF market was valued at $2.37 billion in 2026 and is forecast to reach $10.27 billion by 2032, reflecting the scale of capital and production capacity still needed to meet mandated blending ratios across global aviation. AirPlant One represents one data point in that build-out, but it is a structurally important one: proving that a fully synthetic, electricity-and-CO₂-derived jet fuel can be produced at commercial scale de-risks the technology for project financiers, airline offtake signatories, and the OEM community designing next-generation narrowbodies and widebodies around SAF compatibility.
For engine manufacturers and airframe OEMs, a reliable domestic eSAF supply chain changes the calculus on future aircraft programmes. Drop-in compatibility means no hardware redesign is required today, but a stable, growing eSAF volume gives OEMs confidence to certify higher blend ratios and, eventually, 100% synthetic fuels — a target that several engine programmes are already pursuing in parallel.
