Electric aircraft and sustainable aviation fuel (SAF) are two key technologies helping the aviation industry to reduce its carbon footprint. Therefore, long-term zero-emission flying is possible with electric aircraft, particularly for short distances. However, SAF, a biofuel combination that can cut emissions by up to 80%, is the most practical option for short-term emission reduction.

Sustainable aviation fuel (SAF) was first tested on a commercial aircraft in 2008, and in 2011, it received approval to be used in aircraft operations. Since then, significant progress has been made. The sources state that:

By 2024, over 100 producers in 31 countries had identified and were implementing 40 SAF initiatives.

About 50 airlines, which represent 40% of all air travel worldwide, have committed to a 5%–30% reduction in jet fuel consumption by 2030.

What is Sustainable Aviation Fuel (SAF)?

Sustainable aviation fuel (SAF) is cleaner and more environmentally friendly option for aviation industry. It is made from renewable sources like waste oils, agricultural leftovers, and even carbon captured from the air. Thus, one of the main advantages of SAF is that it can be used in modern aircraft engines without any modifications.

Currently, commercial flights are allowed to use a mix of up to 50% SAF with conventional jet fuel. However, the aviation industry is working towards making 100% SAF flights a reality in the near future.

Key Feedstocks & Production Pathways for SAF

Sustainable Aviation Fuel is produced using several innovative technologies and a variety of renewable feedstocks. Common sources include cooking oil, municipal solid waste and non-food crops. These materials are processed through methods such as:

  • Hydroprocessed Esters and Fatty Acids (HEFA)
  • Fischer-Tropsch synthesis
  • Alcohol-to-Jet (ATJ)
  • FT-SPK with Aromatics 

As the need for SAF rises, these production techniques are becoming more and more popular worldwide. To maximize SAF production, it is very important to understand both the feedstock options and the available technology pathways.

Each feedstock and production method must be approved by ASTM (American Society for Testing and Materials) before being used commercial. This promise that the fuel meets strict standards for safety and performance in commercial aircraft.

Environmental Benefits of SAF

The environmental benefits of using SAF are as follows:

Contributes to Cleaner Air:

The biogenic feedstocks used to make SAF natural to absorb carbon dioxide as they grow, which helping reduce overall carbon emissions. Additionally, SAF contains few sulfur and aromatic compounds, which allowing aircraft engines to burn cleaner and release significantly less harmful pollutants than traditional jet fuels.

Creates New Economic Opportunities:

There will be more supply of SAF as demand increases, which will lead to significant economic benefits, especially in rural areas where feedstocks are produced.

Enhances energy security:

Sustainable Aviation Fuel (SAF) can be made from different renewable sources, which helps reduce the aviation industries depend on fossil fuels. Using these alternatives improves long-term energy security and offers a more stable and reliable fuel supply, even when oil markets are changing.

The Rise of Electric Aircraft

In addition to SAF, electric planes are becoming an important factor in helping environment friendly flying. These planes have far lower operating expenses and zero in-flight emissions because they are fully battery or hybrid powered. Although the majority of the current models are made for short-haul travel, this range can be increased over years by fast developments in aviation technology.

Leading Electric Plane Startups

All electric or hybrid aircraft are being developed by companies such as Joby Aviation, Lilium, and Vertical Aerospace. A number of firms are creating innovative technologies for a sustainable future of air travel to electric aircraft for regional and even long-haul routes and eVTOLs for urban air mobility.

Flight Range & Charging Infrastructure

Electric aircraft currently have limited flight ranges, typically suitable for short-haul routes under 300 miles. The Advances in battery technology such as improvement in energy density and efficiency are gradual increasing these ranges and making longer regional flights more possible in the near future.

  • A key factor of electric aviation is developing a reliable and widespread charging infrastructure.
  • Airports need to install fast and compatible charging stations designed specifically for electric aircraft, which can also serve ground support vehicles.
  • This infrastructure must be integrated careful with existing airport power systems to ensure efficient operations and quick turnaround times for flights. 

Therefore, by improving battery performance and building strong charging networks are the key factors to make electric aviation industry more clean and practical option for short to long distance flights.
