Twelve has opened AirPlant One in Moses Lake, Washington, which the company describes as America’s first commercial-scale plant producing its trademarked E-Jet fuel via the power-to-liquid (PtL) pathway. The plant uses Twelve’s electrochemical process to convert captured CO2, water and renewable electricity into e-Jet SAF and e-naphtha. Alaska Airlines is the physical-fuel offtaker, with the first volumes scheduled for regular domestic flights out of the Pacific Northwest. Microsoft holds a SAF offtake on a book-and-claim basis through its Climate Innovation Fund and is a strategic investor in Twelve. Twelve has raised approximately $645 million across its funding rounds to date, with Alaska Star Ventures among the investors.
The superlative worth reading carefully is what kind of first this is. The US already has commercial-scale SAF production via the HEFA route (Calumet’s Montana Renewables, Diamond Green Diesel, World Energy Paramount) and via alcohol-to-jet (LanzaJet Freedom Pines). Infinium has been operating Project Pathfinder in Corpus Christi as a commercial e-fuels facility producing eSAF, eDiesel and eNaphtha since 2023, so a flat “first commercial-scale PtL plant in the US” superlative does not survive contact with the existing landscape. The honest framing is that AirPlant One is the first US PtL plant purpose-built and certified specifically for airline jet-fuel offtake at commercial scale, anchored by a physical airline customer and a corporate book-and-claim partner. That distinction matters because the e-SAF lane has lagged the FID timeline implied by the ReFuelEU Aviation e-SAF sub-mandate, which steps in at 1.2 percent of EU jet fuel from 2030 (averaged across 2030 and 2031) and rises to 2 percent in 2032.
We broke ground on AirPlant One with a simple thesis: that the fuels powering the global economy could be made from renewable electricity and air.
That framing, from Twelve Co-Founder and CEO Nicholas Flanders, identifies the longer-arc bet. The structure of AirPlant One is what makes the proof point bankable. Twelve has not specified the CO2 source in its launch release; downstream trade-press coverage has pointed to point-source capture from an ethanol producer with later supply from regional pulp and paper facilities, and the Columbia River hydropower complex providing electricity. The CO2-source disclosure is the detail worth watching, because the 45Z Clean Fuel Production Credit value and any EU book-and-claim recognition will hinge on what the carbon-intensity calculation treats the input as. The article output is split between e-Jet for Alaska and e-naphtha that Twelve has supplied to Mercedes-Benz, PANGAIA and Procter & Gamble through proof-of-concept partnerships. That second revenue stream is part of how the plant covers fixed cost while the SAF market is still thin.
The corporate offtake structure tracks the SAFc book-and-claim family that has scaled across 2024 and 2026. Microsoft holds the environmental attributes via a SAF offtake agreement on a book-and-claim basis, while Alaska takes physical delivery for its own flights. It is the same family of attribute-decoupling that American Airlines and Google formalized at registry scale through the SAFc Registry earlier this month, applied here in a single-asset primary-offtake configuration rather than as a registry-mediated certificate purchase. Ryan Spies, Managing Director of Sustainability at Alaska Airlines, and Melanie Nakagawa, Corporate Vice President and Chief Sustainability Officer at Microsoft, framed the agreement around long-term commitment as the enabling condition for commercial PtL production.
Two things the announcement does not address are worth holding onto. Twelve has not disclosed AirPlant One’s nameplate capacity in its release; trade press has reported an initial run rate in the tens of thousands of gallons per year, which would put the plant in early-commercial-ramp territory rather than at the scale of a mature HEFA facility. And the project is not directly addressed by the 45Z Clean Fuel Production Credit unless Twelve has secured the relevant CI certification under the 45ZCF-GREET model that the Department of Energy updated this week. The forward read is whether the Moses Lake structure (a single-asset PtL plant plus a paired physical and book-and-claim offtake) can move the next US PtL projects through FID at speed. The US PtL lane has gone from a thin pre-commercial slate to a Twelve-anchored commercial plant in this announcement. The question is now the slope.
