Sustainable Aviation Fuel (SAF) is a clean substitute for fossil jet fuels. Rather than being refined from petroleum, SAF is produced from sustainable feedstocks such as waste oils from a biological origin, agri residues, or non-fossil CO2.
SAF is a so-called drop-in fuel, which means that it can be blended with fossil jet fuel and that the blended fuel requires no special infrastructure or equipment changes. Once it is blended, our fuel is fully certified (ASTM D1655/ DEFSTAN 91-91) and has the same characteristics and meets the same specifications as fossil jet fuel.
Since the first commercial flight operated by KLM in 2011, more than 150,000 flights were powered by SAF. To date, SkyNRG has supplied SAF that’s produced from Used Cooking Oil with the so-called HEFA-technology. But we are not limited to a single feedstock or technology. As long as the SAF meets both the technical specifications as well as our sustainability criteria, we are willing to consider any feedstock-technology combination.
We all love to fly! But there’s a downside. The environmental impact of air travel is significant, and it is growing rapidly. It is essential for economies and businesses globally and enables us to visit family & friends and discover foreign countries & cultures. But the impact of aviation on our carbon footprint is significant and growing rapidly.
Aviation currently accounts for approximately 2-3% of manmade global carbon emissions. Without timely action, aviation could consume up to 22% of the global carbon budget by 2050. To maintain growth and at the same time address its environmental impact, the aviation industry has committed to carbon-neutral growth per 2020 and reducing net aviation carbon emissions to 50% below 2005 levels by 2050.
Technology, operations, and infrastructure improvements are effective ways to reduce emissions. More than 99% of airline emissions and approximately 50% of airport emissions are related to the combustion of jet fuel. Although increased energy efficiency and reduction in energy demand are effective ways to reduce fuel consumption and related greenhouse gas emissions, these improvements do not offer a sole solution to aviation-related emissions.
Since aircraft are not able to switch to alternative energy sources (like hydrogen or electricity) in the foreseeable future, aircraft will remain to rely on liquid fuels. Therefore, sustainable aviation fuel made from renewable feedstock is one of the most important short term options to significantly reduce the industry’s carbon footprint and at the same time also reduce the dependency on the petroleum industry.
1. CO2 reduction
We aim for at least 80% CO2 emissions reduction compared to conventional jet fuel. The key difference lies in the source of carbon. Fossil fuels release additional carbon that was previously stored in reservoirs. SAF recycles CO2 emissions that were emitted previously and subsequently absorbed from the atmosphere during biomass production.
2. Improved local air quality
In addition to the reduction of total life cycle CO2 emissions, SAF can also reduce direct emissions: particulate matter (PM) with up to 90% and sulphur (SOX) with 100%, compared to conventional jet fuel. Reducing these emissions both impact local air quality, in particular in areas with a high density of flight movements, such as airports.
3. Improved fuel efficiency
Studies have shown that sustainable aviation fuel has a higher energy density than conventional jet fuel. On top of that, SAF yields an improved fuel efficiency (1.5% – 3%), resulting in higher payload conditions or extended range.
Benefits of a regional SAF supply chain. Additional benefits include a region’s increased energy security, reduced volatility of jet fuel supply and price, and economic development through investments and job creation.
