6 Things You Didn’t Know About Sustainable Aviation Fuel: A Beginner’s Guide
You may have heard about Sustainable Aviation Fuel, but still don’t fully comprehend what it is or how it works. This blog will highlight the top 6 things you didn’t know about Sustainable Aviation Fuel (or as we like to call it: SAF).
SAF is a sustainable alternative for Jet A1 fuel
SAF stands for Sustainable Aviation Fuel. SAF is a liquid and clean substitute for fossil kerosene produced from sustainable resources. These can include waste oils from biological origin, agricultural residues or CO2 captured from the air It significantly reduces CO2 emissions from air transportation and has already fueled over 330,000 commercial (source).
SAF is a drop-in fuel, meaning it is a completely interchangeable substitute for fossil kerosene. After blending the neat SAF with fossil kerosene, the blended SAF requires no special or expensive changes in infrastructure or equipment.
There are multiple ways to make SAF
There are many different to produce sustainable aviation fuel. These conversion technologies can transform a wide range of biomass and waste feedstocks (including CO2) into fossil kerosene. Currently, there are different technology platforms certified to produce SAF for use in commercial aviation. You can find out more about them here.
SAF can achieve up to 85% reduction in carbon emissions compared to fossil kerosene
The SAF market currently accounts for less than 0.1% of jet fuel consumption
The SAF market is still small compared to fossil kerosene production – it is currently less than 0.1% of global jet fuel consumption. This is because of the current lack of dedicated SAF production plants. However, the demand for SAF is rapidly growing. Innovation and the scaling up of production plants are key to increasing the availability of these fuels.
The “green premium” is one of SAF’s biggest challenges
The prominent challenge SAF faces is the “green premium” – the price difference between fossil kerosene and SAF. Because of this premium, airlines are limited in the volume of SAF they can buy. But there is a solution to this: organizations forming partnerships beyond the aviation industry to increase SAF uptake, bring this premium down, and push the energy transition in this industry.
It is especially important for corporates to take a stand and lead this transition, since many of them have significant aviation-related footprints – think of business travel and air freight. There are enough sustainable feedstocks available to fuel all flights – the next step is to make this economically, environmentally, and socially viable.
