Rolls-Royce (Booth 2043) has signed a memorandum of understanding to test Alder Fuels’ Greencrude sustainable aviation fuel (SAF). Greencrude utilizes sustainable biomass, including regenerative grasses, forest residues, and agricultural waste products, and can be converted into a drop-in fuel using existing bio and petroleum refinery infrastructure. It yields a greenhouse gas reduction of more than 80 percent compared with straight jet-A fuel. 

“Through our partnership with Alder Fuels, we are taking the next steps on our journey to net zero [emissions] and are committed supporters of the UN [United Nations] race to zero goal of 10 percent SAF use across aviation by 2030,” said Frank Moesta, Rolls-Royce senior v-p strategy and future programs, business aviation. The testing will generate data used by ASTM International for the development of a 100 percent SAF specification. Rolls-Royce has previously committed that all of its Trent and business aviation engines will be 100 percent SAF compatible by 2023. They are already certified to operate on a 50 percent SAF blend. 

Alder is backed by Honeywell UOP, United Ventures, AvFuel, Boeing, Directional Aviation, the U.S. Defense Logistics Agency, the Department of Energy, and the National Renewable Energy Laboratory.
