Lignin breakthrough unlocks cost-competitive, carbon-neutral jet fuel
A simple, cheap pretreatment promises to radically cut the price of sustainable aviation fuel (SAF) made from waste wood biomass – potentially making it cost-competitive with fossil-based jet fuel, while cutting down emissions by up to 80%.SAF isn't a perfect green solution to aviation – indeed, no perfect solution exists at this point. Running SAF instead of jet fuel still produces carbon dioxide – but it's a higher-purity fuel, producing up to 3% more energy while burning cleaner, with heavily reduced sulfur and…
