Readers ask: Which Aviation Biofuels Are Certified?

Which airlines are using biofuels?

United and Delta down for millions of gallons In 2019, United began trialing biofuel with its “Flight for the Planet” from Chicago to Los Angeles, using 70% regular jet fuel and 30% biofuel. The same year, the carrier committed $40 million in investments into the acceleration of biofuel production.

Can biofuel be used in aircraft?

An aviation biofuel or bio-jet-fuel or bio- aviation fuel (BAF) is a biofuel used to power aircraft and is said to be a sustainable aviation fuel (SAF). The first test flight using blended biofuel was in 2008, and in 2011 blended fuels with 50% biofuels were allowed in commercial flights.

What is SAF aviation fuel?

SAF stands for sustainable aviation fuel. It’s produced from sustainable feedstocks and is very similar in its chemistry to traditional fossil jet fuel. Using SAF results in a reduction in carbon emissions compared to the traditional jet fuel it replaces over the lifecycle of the fuel.

Are aviation biofuels ready for take off?

The aviation industry has committed to reducing carbon emissions by 50% from their 2005 level by 2050. This is reflected in the IEA’s Sustainable Development Scenario (SDS), which anticipates biofuels reaching around 10% of aviation fuel demand by 2030, and close to 20% by 2040.

What are disadvantages of biofuels?

Drawbacks of bioethanol include: The amount of arable land needed to grow the crops in order to produce a large amount of fuel is immense. There is large debate about the shift of crop use from food production to fuel production and the fear that it will impact the prices of food around the world.

What can replace jet fuel?

New Alternative Jet Fuel Approved

  • Synthesized Iso-parafins (SIP) which convert sugars into jet fuel.
  • Hydro-processed Esters and Fatty Acids Synthetic Paraffinic Kerosene (HEFA-SPK), which use fats, oils and greases.
  • Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK) and Fischer-Tropsch Synthetic Kerosene with Aromatics (FT-SKA).

Is biofuel more expensive than jet fuel?

That’s because biofuels are currently very costly — “approximately two to three times as expensive as conventional jet fuel,” a spokesperson for the Dutch airline KLM said. Currently, many airlines, including KLM, use biofuel made from used cooking oil.

How much does aviation biofuel cost?

Biofuel price is taken as 2–7 times the price of conventional air transport fuel. Therefore, the price of air transport biofuel would be 156–547 $/b in 2020, 176–617 $/b in 2025 and 199–696 $/b in 2030.

How much is a gallon of jet fuel?

170.8 Cents (US dollars) per Gallon.

Is aviation fuel bad for the environment?

Burning jet fuel releases greenhouse gases such as carbon dioxide into Earth’s atmosphere and oceans. Greenhouse gases block heat from escaping from the atmosphere, causing temperatures to rise just like in a greenhouse.

How is SAF fuel made?

Sustainable Aviation Fuel ( SAF ) is a clean substitute for fossil jet fuels. Rather than being refined from petroleum, SAF is produced from sustainable resources such as waste oils from a biological origin, agri residues, or non-fossil CO2.

What is jet fuel made of?

Jet fuels are primarily derived from crude oil, the common name for liquid petroleum. These jet fuels can be referred to as petroleum-derived jet fuels. Jet fuels can also originate from an organic material found in shale, called kerogen or petroleum solids: that can be converted by heat to shale oil.

How much sustainable aviation fuel is used each year?

Over the same period, the FAA projects that jet fuel consumption will increase from 24.08 billion gallons to 30.64 billion gallons per year.

Is jet fuel fossil fuel?

Aircraft today are powered by liquid aviation fuel, made mostly from fossil fuel sources. CO2 absorbed by plants during the growth of biomass is roughly equivalent to the amount of carbon dioxide produced when the fuel is burned in a combustion engine and returned to the atmosphere.

What alternative fuel was used in the aviation sector in August 2018?

Biojet fuel is low cost and helps in significantly reducing carbon emissions. “It has the potential to reduce our dependence on traditional aviation fuel by up to 50 per cent on every flight and bring down fares,” Ajay Singh said.
