RE: SAF 100 per cent by next year! The required was only 50 per cent15 Jun 2022 09:39
In short supply
United Airlines has also operated a domestic narrowbody passenger flight for which one of the two engines was powered solely by SAF. Meanwhile, even if a certification for 100% SAF operations was approved by regulators tomorrow, there is hardly enough of the stuff to go around.
Today, SAF accounts for approximately 1% of jet fuel uplifted globally. Despite a significant increase in investments over the past year, it will be a long time before it will make any substantial dent in aviation's overall emissions. And it's going to need the support of policymakers to get there, either through mandates, incentives, or a combination of both, to get there..........
Taken from the above link ...what timescale do you envisage this happening on a commercial basis....? gla.
