Neste’s SAF biofuel tested in Boeing Emirates flight in 2023
The United Kingdom has taken a significant step in advancing sustainable aviation by approving an increase in the co-processing blend limit for Sustainable Aviation Fuel (SAF) from 5% to 30%. This decision, endorsed by the UK Ministry of Defence and incorporated into Defence Standard 91-091, aims to accelerate the production and adoption of SAF within the aviation sector.
Safety is paramount in aviation fuel standards. The updated Defence Standard 91-091 ensures that SAF produced through co-processing meets stringent aviation fuel specifications. This standard aligns with global benchmarks, such as ASTM D1655, guaranteeing that the fuel is compatible with existing aircraft engines and infrastructure. Industry stakeholders, including BP and the International Air Transport Association (IATA), have collaborated to achieve this milestone, emphasizing the fuel’s safety and performance.
Britain’s Leadership in Sustainable Aviation
Virgin Galactic astronauts. Will space travel be sustainable? Sustainable Space Fuels?
It’s not just Virgin Atlantic or the hope for sustainable space travel: By increasing the co-processing blend limit, the UK positions itself as a leader in sustainable aviation. This move allows for the integration of renewable feedstocks, such as waste oils and fats, into existing refinery processes, facilitating a faster and more cost-effective path to SAF production. The approach reduces the need for constructing new facilities, thereby accelerating the availability of cleaner aviation fuels.
While the adoption of SAF represents a significant advancement in reducing aviation’s carbon footprint, it’s important to recognize that SAF is not a complete solution. The production and use of SAF can reduce greenhouse gas emissions by up to 80% compared to conventional jet fuel, depending on the feedstock and production methods.
However, challenges remain, including feedstock availability, production scalability, and economic factors. Therefore, while SAF contributes to more sustainable air travel, achieving guilt-free flying will require a combination of technological advancements, policy support, and broader systemic changes in the aviation industry.
Looking for a green and principled investments in SAF?
Several companies are actively involved in the research, development, and production of sustainable aviation fuels. Some prominent examples include:
- Neste: A Finnish company known for its renewable diesel and sustainable aviation fuel production. Neste is one of the largest producers of SAF globally and has partnerships with various airlines and airports.
- Gevo is a NASDAQ-traded US-based company that focuses on developing bio-based alternatives to petroleum-based products. They are actively working on producing SAF from renewable feedstocks such as corn, wood waste, and other sustainable sources.
- Velocys is a British company specializing in sustainable aviation fuels and renewable diesel. They use gasification and Fischer-Tropsch technology to convert waste biomass into fuels suitable for aviation.
- World Energy: This company, formerly known as AltAir Fuels, is based in the United States and produces renewable diesel and SAF from various feedstocks, including waste fats, oils, and greases.
- Shell: While primarily known as an oil and gas company, Shell has been investing in renewable energy and alternative fuels, including sustainable aviation fuels. They are involved in various projects and partnerships aimed at developing SAF technologies.
- SkyNRG: A Dutch company dedicated to developing and supplying sustainable aviation fuels. They collaborate with airlines, airports, and other stakeholders to promote the adoption of SAF in the aviation industry.
- The NASDAQ-traded XCF. XCF Global aims to be a leading producer of SAFs with an initial annual production capacity of 38 million gallons following the acquisition of New Rise Renewables, which owns a flagship plant and adjacent site in Reno, Nevada.XCF will be the only pure-play public SAF producer in the US market, with competition mainly coming from legacy crude oil providers.
