The aviation industry is at a critical juncture in its sustainability journey, and the latest insights from industry analyst Thomas Mielke at the Sustainable Vegetable Oils Conference (SVOC) underscore both challenges and opportunities in the production of Sustainable Aviation Fuel (SAF). As the demand for SAF grows, driven by the need to reduce carbon emissions in air transportation, concerns around feedstock availability have come into sharp focus.
The Role of Feedstocks in SAF Production
SAF is a game-changing alternative to traditional fossil-based jet fuels, made from a variety of renewable, non-petroleum feedstocks such as used cooking oil, municipal waste, and agricultural residues. These sustainable fuels can be blended with conventional jet fuel, reducing greenhouse gas emissions by up to 80% depending on the blend. However, one of the key challenges for widespread adoption of SAF is securing a reliable and sustainable supply of feedstocks.
Mielke highlighted that the global supply of certain feedstocks, including used cooking oil, tallow, and other non-food materials, has not kept pace with the increasing demand. This shortage is likely to increase reliance on plant oils like palm oil, soybean oil, sunflower oil, and rapeseed oil, all of which are also essential for food production.
A Shifting Landscape for Vegetable Oils
The global vegetable oil market is undergoing a transformation. Mielke noted a shift towards soybean, sunflower, and rapeseed oils as alternatives to palm oil, which has faced significant sustainability and certification challenges in recent years. The decline in palm oil production since 2019, due to a combination of factors like insufficient replanting and rising production costs, has only intensified the pressure on alternative oil crops.
This shift is likely to drive up prices for vegetable oils, which will, in turn, affect the biofuel industry, including the production of SAF. As Mielke pointed out, the energy sector already consumes 20% of the world’s oils and fats, and SAF will further strain the supply chain, making it crucial for producers and consumers to adapt to tightening supplies and rising costs.
What This Means for the Future of SAF and Biofuels
The increased demand for SAF will inevitably impact the biodiesel and Hydrotreated Vegetable Oil (HVO) markets. With electric vehicles gaining traction in the transportation sector, the demand for biodiesel may decrease, but the need for SAF in aviation will continue to grow. In fact, biodiesel production has nearly doubled over the past decade and is estimated to reach 62.7 million tons this year, according to Mielke.
However, with the potential tightening of vegetable oil supplies, industry players will need to innovate and explore new feedstock options to meet the increasing demand for SAF. Sustainable feedstocks like municipal waste, waste gases, and agricultural residues will play a crucial role in ensuring the long-term viability of SAF and biofuels.
