As the aviation industry faces increasing pressure to reduce carbon emissions, sustainable aviation fuel (SAF) has emerged as a promising solution for a greener future in the skies. In a world where a single long-haul flight can produce as much carbon dioxide (CO₂) as an individual in some countries might generate in an entire year, the need for eco-friendly alternatives is clear. This blog explores the state of SAF in 2024, its potential, and how industry players like VURDHAAN contribute to a more sustainable aviation sector.
The Rise of Sustainable Aviation Fuel (SAF)
SAF represents a significant shift from conventional petroleum-based jet fuels to renewable alternatives. Derived from non-petroleum sources such as used cooking oil, animal waste, and forestry residues, SAF can reduce net CO₂ emissions by up to 80% over its lifecycle. This reduction is achieved by capturing and utilizing existing carbon, essentially closing the carbon loop instead of adding new carbon to the atmosphere.
In a substantial breakthrough, Virgin Atlantic’s transatlantic flight from London Heathrow to JFK International Airport recently showcased the power of 100% SAF, with a blend comprising 88% Hydroprocessed Esters and Fatty Acids (HEFA) and 12% Synthetic Aromatic Kerosene (SAK). This milestone reflects the growing interest in and capability of SAF to significantly cut emissions in aviation.
Challenges in Scaling Up SAF
Despite its potential, SAF currently comprises less than 1% of the aviation fuel market due to high production costs and limited infrastructure. SAF from waste oils, for instance, is around 50% more expensive than traditional jet fuel, while synthetic SAF can be up to three times the cost. The lower energy density of SAF compared to conventional jet fuel also presents a logistical challenge for long-haul flights, as larger volumes of SAF may be needed to travel the same distance.
However, governments and industries are rallying behind SAF production. The U.S. has committed to producing 3 billion gallons of SAF by 2030, aiming to reduce aviation emissions by 20%, while the UK mandates that 10% of jet fuel must come from sustainable sources by the same year. As policy support intensifies, experts predict SAF will reach scalability in the coming decade, potentially enabling widespread adoption by 2030.
The Future of SAF: A Global Market Ready to Expand
Since 2008, when SAF was first trialed on commercial flights, its application has grown exponentially. More than 450,000 flights have utilized SAF in various blends, with over 50 airlines worldwide joining the effort to reduce their carbon footprints. Precedence Research forecasts that the SAF market, valued at $616.91 million in 2023, could exceed $14 billion by 2032. Such rapid growth reflects both the rising demand for SAF and the aviation sector’s commitment to sustainable alternatives.
The International Air Transport Association (IATA) anticipates that SAF will deliver 65% of the reductions needed for aviation to reach net-zero emissions by 2050. With this ambitious target in mind, industry stakeholders are actively investing in research, technology, and policy frameworks that will enable SAF’s expansion in the coming years.
