United, Honeywell invest in new clean tech venture from Alder Fuels

United and Honeywell have announced a joint multimillion-dollar investment in Alder Fuels – a cleantech company that is pioneering technologies for producing sustainable aviation fuel (SAF) at scale by converting abundant biomass, such as forest and crop waste, into sustainable low-carbon, drop-in replacement crude oil that can be used to produce aviation fuel. When used together across the fuel lifecycle, the Alder technologies, coupled with Honeywell’s Ecofining process, could have the ability to produce a carbon-negative fuel at spec with today’s jet fuel. The goal of the technologies is to produce fuel that is a 100% drop-in replacement for petroleum
