With its 2% share of the world’s greenhouse gas emissions, the aviation sector is one of the most polluting in the world. Sustainable aviation fuel (SAF), a viable substitute for jet fuel derived from fossil fuels, can aid in lowering these emissions.
SAF is produced using renewable resources such spent cooking oil, agricultural byproducts, and forestry debris. It can be used as a pure fuel or combined with jet fuel derived from fossil fuels. Compared to jet fuel made from fossil fuels, SAF can cut greenhouse gas emissions by up to 80%.
SAF costs more than fossil fuel-based jet fuel at the moment, but as the market for SAF expands, costs are anticipated to decline. SAF cost of $2.50 per gallon in 2022 compared to fossil fuel-based jet fuel’s cost of about $1.50 per gallon. The International Air Transport Association (IATA) predicts that by 2030, the cost of SAF may be comparable to that of jet fuel derived from fossil fuels.
There are numerous businesses that are creating and manufacturing SAF. Air France-KLM, British Airways, Boeing, Delta Air Lines, Shell, Total Energies, and others are a few of the top businesses. These businesses are putting money into SAF production facilities and trying to lower the cost of SAF.
The creation and application of SAF are supported by a number of government programmes. Research and development for SAF is being funded in the US by the Department of Energy. By 2030, the European Union likewise plans to use 5% SAF.
The aviation industry is committed to decarbonizing air travel. SAF is a key part of this effort. As the price of SAF comes down and more production facilities are built, SAF is expected to play an increasingly important role in reducing the environmental impact of air travel.
Here are some additional details about sustainable aviation fuel:
- The most common feedstocks for SAF are used cooking oil, agricultural waste, and forestry residues.
- SAF can be produced using a variety of technologies, including Fischer-Tropsch synthesis, pyrolysis, and hydrotreating.
- The production of SAF can create jobs and boost economic growth in rural areas.
- SAF is a drop-in fuel, which means it can be used in existing aircraft without any modifications.
- The demand for SAF is expected to grow rapidly in the coming years.
Some of the challenges to the widespread adoption of SAF include:
- The high cost of production
- The limited availability of sustainable feedstocks
- The need for government policies to support the development and use of SAF
Despite these challenges, sustainable aviation fuel is a promising technology with the potential to significantly reduce the environmental impact of air travel. As the cost of production comes down and more production facilities are built, SAF is expected to play an increasingly important role in decarbonizing the aviation industry.
