The HEFA Feedstock Crunch Is Coming for SAF
Is alcohol-to-jet the easy answer?
Aviation is critical infrastructure for global connectivity and economic growth—but it is also one of the hardest sectors to decarbonize. Sustainable aviation fuel (SAF) has emerged as the leading solution. Driven by expanding regulation, particularly in the EU, SAF demand is rising fast, placing growing pressure on feedstock supply and accelerating the need for alternative conversion pathways.
