Self-proclaimed "carbon transformation" company Twelve has begun building in the US state of Washington a sustainable aviation fuel plant designed to use renewable energy and water to convert CO2 into its branded "E-Jet" fuel. Berkeley, California-based Twelve expects production of E-Jet fuel will begin in mid-2024 at a capacity of five barrels per day (40,000 gallons per year). It adds that as a power-to-liquid SAF with up to 90% lower lifecycle greenhouse gas (GHG) emissions compared with petroleum-based jet fuel, E-Jet fuel meets the ASTM International specifications and works with existing aircraft and airport infrastructure. "[E-Jet fuel] faces no real constraints on feedstock, thus offering the best viable long-term solution for addressing GHG and other emissions from the aviation sector," the company says. Attending the 11 July ground-breaking event in Moses Lake, Washington were that state's governor Jay Inslee; Twelve co-founder and chief science officer Etosha Cave; Alaska Airlines VP of strategic sourcing and supply chain Ann Ardizzone; and Brandon Middaugh, senior director of Microsoft's Climate Innovation Fund. "We’re proud to welcome Twelve to Washington state," Inslee says. "By producing E-Jet fuel at scale, Twelve will boost our soaring aviation industry and our thriving clean energy economy." In July 2022, Twelve disclosed that Alaska Airlines and Microsoft had signed on as partners in SAF programme. Those two companies, as well as e-commerce firm Shopify, will be the first entities to receive products from the Moses Lake plant under existing agreements, Twelve says.
