Without a cap, the ICCT warns that HEFA SAF made from UCO will make up virtually all of the EU’s SAF blending mandate apart from the power-to-liquids (PTL) submandate: “HEFA fuel is the only commercially mature jet fuel pathway and can only be produced with waste oils under ReFuelEU Aviation; it is likely that the entirety of an SAF mandate, outside of a submandate for another kind of SAF, power-to-liquids, would be met with waste oils like UCO,” the ICCT claims.
