Navigating the UK's Sustainable Aviation Fuel Transition
Key Ideas
  • The UK introduced a Sustainable Aviation Fuel (SAF) mandate starting at 2% in 2025, aiming to reach 22% by 2040 for significant carbon savings.
  • SAF production in the UK increased by 188% from 2022 to 2023, but challenges remain in meeting the escalating demand for SAF by 2030 and beyond.
  • The government enforces the SAF mandate through a traceable certificate scheme for fuel suppliers, with incentives for innovation and feedstock diversification.
  • Different SAF production pathways, such as HEFA, corn-based biofuels, and alcohol-to-jet processes, offer varying pros and cons in terms of cost and sustainability.
The UK's Department for Transport initiated a Sustainable Aviation Fuel (SAF) mandate on 1 January, requiring a minimum of 2% SAF in jet fuel by law, with targets set to increase to 22% by 2040. Despite a significant 188% increase in SAF production from 2022 to 2023, challenges loom in meeting the escalating demands, with the UK currently covering only a fraction of the needed supply. The mandate is enforced through a certificate scheme, allowing fuel suppliers to trade certificates to meet obligations efficiently. The government incentivizes innovation and feedstock diversification to meet the SAF requirements sustainably. The article delves into various SAF production pathways like HEFA, corn-based biofuels, and alcohol-to-jet processes, highlighting their pros and cons. While SAF presents a promising solution for decarbonizing aviation, the UK faces hurdles in scaling up production to meet the ambitious targets, underlining the importance of continued innovation and sustainable practices in the aviation fuel sector.
