Sustainable Aviation Fuel and Energy Security: Beyond HEFA Pathways

Sustainable aviation fuel (SAF) is becoming a critical tool for both decarbonization and energy security. While HEFA fuels from waste oils currently lead the market, feedstock limitations mean the industry must pivot toward alcohol-to-jet and gasification pathways to scale effectively. Long term security depends on e-SAF, which uses captured CO2 and green hydrogen. Although production costs remain high, these synthetic fuels offer the most flexibility by removing reliance on agricultural land and volatile global oil markets.

The mention of EU regulatory roadmaps to cover the green premium is the most important part here. Without those subsidies or mandates, e-SAF stays a theoretical exercise because the cost gap with kerosene is too wide for airlines to absorb.

Exactly. And for e-SAF to actually scale, we need a massive increase in electrolyzer capacity. I wonder how much additional grid load these plants will actually require before they become viable.

Interesting breakdown of the HEFA tipping point. It is a bit worrying that Europe still imports a huge chunk of its used cooking oil. That just replaces one import dependency with another.

The gasification of municipal waste mentioned for the UK plant is the more practical play. Using trash as feedstock is a better bet for local supply than hoping for enough recycled frying oil.
