How Sustainable Aviation Fuel Can Reduce the Environmental Impact of Flying

Flying is one of the most convenient and popular ways to travel, but it also comes with a high environmental cost. According to the International Civil Aviation Organization, aviation accounts for about 2% of global carbon dioxide emissions, and this figure is expected to rise as air travel demand increases.

But what if there was a way to make flying more eco-friendly, without compromising on performance, safety or affordability? That’s where sustainable aviation fuel (SAF) comes in. SAF is a type of fuel that is made from renewable sources, such as waste oils, biomass or synthetic gases, and can reduce the carbon footprint of flying by up to 80%.

In this blog post, I’ll explain what SAF is, how it works, and why it’s a game-changer for the aviation industry and the environment.

What is SAF?

SAF is a term that refers to any type of jet fuel that is produced from renewable or low-carbon sources, rather than from fossil fuels. SAF can be blended with conventional jet fuel or used as a drop-in replacement, meaning that it can be used in existing aircraft engines and infrastructure without any modifications.

SAF can be made from various feedstocks, such as:

• Waste oils: These are oils that are derived from used cooking oil, animal fat or industrial waste. They can be processed into SAF through a process called hydroprocessing, which removes oxygen and other impurities from the oil and converts it into hydrocarbons.
• Biomass: These are organic materials that are derived from plants or animals, such as wood, crops or algae. They can be processed into SAF through a process called gasification or pyrolysis, which converts the biomass into a gas or liquid that can be further refined into hydrocarbons.
• Synthetic gases: These are gases that are derived from renewable electricity, such as hydrogen or carbon dioxide. They can be processed into SAF through a process called Fischer-Tropsch synthesis, which combines the gases into long-chain hydrocarbons.

How does SAF work?

SAF works in the same way as conventional jet fuel, by providing energy to the aircraft engine through combustion. However, SAF has some advantages over conventional jet fuel, such as:

• Lower carbon emissions: SAF can reduce the carbon emissions of flying by up to 80%, depending on the feedstock and production method. This is because SAF uses carbon that is already in the atmosphere or in the biosphere, rather than adding new carbon from fossil fuels. SAF also has lower sulfur and particulate emissions, which can improve air quality and reduce contrails.
• Higher energy density: SAF can have a higher energy density than conventional jet fuel, meaning that it can provide more energy per unit of volume or mass. This can improve the fuel efficiency and range of the aircraft, as well as reduce the weight and volume of fuel needed.
• Better performance: SAF can have better performance characteristics than conventional jet fuel, such as higher flash point, lower freezing point and lower viscosity. This can enhance the safety and reliability of the aircraft engine, as well as reduce maintenance costs.

Why is SAF important?

SAF is important for several reasons, such as:

• Reducing greenhouse gas emissions: SAF can help the aviation industry meet its climate goals and contribute to the global efforts to limit global warming. The aviation industry has committed to reducing its net carbon emissions by 50% by 2050 compared to 2005 levels, and SAF is a key technology to achieve this target.
• Supporting sustainable development: SAF can support sustainable development by creating new jobs and industries in the renewable energy sector, as well as reducing dependence on fossil fuels and enhancing energy security. SAF can also support social and environmental benefits by using waste materials or promoting biodiversity.
• Increasing consumer demand: SAF can increase consumer demand for air travel by offering a more environmentally friendly option for travelers who are concerned about their carbon footprint. SAF can also increase customer loyalty and brand reputation for airlines who adopt SAF.

Conclusion

SAF is a type of fuel that is made from renewable sources and can reduce the environmental impact of flying. It works in the same way as conventional jet fuel, but has lower carbon emissions, higher energy density and better performance. It is important for reducing greenhouse gas emissions, supporting sustainable development and increasing consumer demand.
