As the global aviation industry continues to expand, its environmental impact remains a critical concern. Currently, the sector accounts for around 2% of global energy-related CO2 emissions and 4% of the EU’s total emissions. Addressing this, Sustainable Aviation Fuel (SAF) is increasingly being recognized as a key component in reducing the sector’s carbon footprint and advancing toward a more sustainable future.
What Exactly is SAF?
Sustainable Aviation Fuel, or SAF, is an innovative alternative to conventional jet fuel. Unlike fossil fuels, SAF is produced from renewable sources such as used cooking oil, agricultural residues, and even municipal waste. Importantly, SAF has the potential to reduce lifecycle greenhouse gas emissions by over 50%, making it a viable solution for lowering the aviation industry’s carbon footprint.
The SAF production process includes feedstock collection, conversion into renewable hydrocarbons, blending with traditional jet fuel, and seamless integration into existing airport infrastructure. With its ability to reduce emissions and its compatibility with current systems, SAF is poised to play a transformative role in decarbonizing aviation.
Current Pathways to SAF
SAF production has progressed significantly, with nine certified pathways making SAF increasingly accessible and viable. These include:
- HEFA (Hydroprocessed Esters and Fatty Acids): The most widely used process, HEFA converts oils and fats into renewable jet fuel and has powered over 95% of SAF flights to date.
- ATJ (Alcohol-to-Jet): This technology uses alcohols like ethanol, transforming them into SAF through a multi-step conversion process.
- Fischer-Tropsch (FT): By converting biomass into hydrocarbons, FT-SAF offers high efficiency with minimal waste, but faces scalability challenges.
- Power-to-Liquid (PtL): PtL uses renewable electricity and captured CO2 to synthesize liquid hydrocarbons, offering a highly sustainable production route.
Each pathway brings its unique strengths, along with challenges, such as cost and feedstock availability. However, governments and industry stakeholders are driving innovation and scaling up production to overcome these hurdles.
The Road Ahead: Regulatory and Financial Support for SAF
To ensure the success of SAF, global governments are offering various incentives, including direct grants, tax credits, and low-interest loans. Carbon pricing mechanisms, such as emissions trading schemes like CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation), further encourage SAF adoption by making high-carbon fuels less economically attractive.
Despite the high initial production costs—currently two to three times that of traditional jet fuel—investment in SAF technology is expected to reduce expenses through economies of scale. Moreover, the aviation sector must increase SAF production exponentially to meet net-zero targets by 2050.
