Turning air into sustainable aviation fuel The report includes a host of examples of global climate technology projects that have been catalysed by Microsoft’ s CIF.
Twelve Twelve uses electrochemical technology to convert captured CO 2 and water into synthetic fuels and chemicals, including SAF. Its flagship product, E-Jet, is a dropin Power-to-Liquid( PtL) SAF made using renewable electricity, water and CO 2.
CIF’ s investment in Twelve supported the scale-up of its Moses Lake, Washington facility and led to SAF offtake for Microsoft. The offtake included bookand-claim accounting, enabling Microsoft to report lower emissions from SAF use without physical delivery.
Microsoft partnered with Alaska Airlines to pioneer the book-and-claim model for SAF procurement.
The report says:“ This approach is especially valuable for global business travel, where direct SAF access is limited as most business travel happens through commercial airlines, instead of company-owned aircraft.
“ Microsoft’ s early participation in the first SAF book-and-claim pilot helped establish a scalable framework that accelerates corporate demand and market growth.”
Following CIF’ s investment, Twelve went on to raise US $ 645m in follow-on funding. sustainabilitymag. com 141
