Microsoft and Alaska Airlines have joined forces with industrial technology company Twelve to bring a commercial-scale synthetic e-fuel plant online, focused on producing cleaner energy for aviation.
AirPlant One is the first facility of its kind at this scale in the US, generating low-carbon jet fuel using captured carbon dioxide, water and renewable electricity. The process highlights the growing role of electrification and carbon utilisation in reshaping fuel supply.
The output is a drop-in synthetic aviation fuel, compatible with existing aircraft and infrastructure, while offering lifecycle CO₂ emissions reductions of up to 90% compared to conventional jet fuel.
Back in 2022, Microsoft and Alaska Airlines committed to purchasing future production from the site, a move that helped Twelve unlock financing, reduce risk and move ahead with construction.
In parallel with the offtake agreement, Alaska Star Ventures, the investment division of Alaska Airlines, took part in Twelve’s US$645m funding round. Microsoft also supported the initiative via its Climate Innovation Fund.
