Is there an alternative to aviation fuel?
Is there an alternative to aviation fuel?
HEFA-SPK fuel is considered as leading alternative replacements for conventional jet fuel by the CAA because of its sustainability. HEFA-SPK was approved by Altair Engineering for use in 2011. HEFA-SPK is produced by the deoxygenation and hydroprocessing of the feedstock fatty acids of algae, jatropha, and camelina.
What kind of fuel do commercial airlines use?
Aviation kerosene is the fuel of choice for aircraft across the globe.
What are the different types of aircraft fuels used in the aviation industry?
A basic distinction is made between four different aviation fuels:
- Jet fuel (Jet A-1, kerosene)
- Kerosene-gasoline mixture (Jet B)
- Aviation gasoline (avgas)
- Biokerosene.
Is SAF safe?
SAF can be made from renewable sources such as used cooking oil, municipal waste and woody biomass. It is a safe, proven fuel, which has the potential to reduce lifecycle emissions by up to 80%, compared with conventional aviation fuel.
What is green aviation fuel?
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 octane is aviation fuel?
The most common avgas is 100 octane, which is a measure of the fuel’s ability to resist premature detonation or “knock.” Avgas is also available at other octanes such as 87 and 130, but they are rare today.
Is avgas a kerosene?
Avgas (aviation gasoline, also known as aviation spirit in the UK) is an aviation fuel used in aircraft with spark-ignited internal combustion engines. Kerosene is also used by most diesel piston engines developed for aviation use, such as those by SMA Engines, Austro Engine, and Thielert.
What is the difference between Avgas and Mogas?
In a nutshell, Mogas which is otherwise known as motor gasoline, is used by ground vehicles, while Avgas is specifically developed for aircraft use. A common oxygenate, ethanol, can cause damage to fuel system hardware and has a low energy content which can reduce aircraft range.
What is the difference between Avgas and jet fuel?
AVGAS, or aviation gasoline, is used for piston-engine aircraft. These types of aircraft fly through the rotation of the propellers which generate the thrust. While Jet Fuel is used for aircraft with turbine-engine jets. These fly with the thrust of expelled air.
What is SAF IATA?
Sustainable aviation fuel (SAF) is the main term used by the aviation industry to describe a non- conventional (fossil derived) aviation fuel. ‘Biofuels’ typically refers to fuels produced from biological resources (plant or animal material).
What is the octane of aviation fuel?
Which fuels are renewable?
Renewable Fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide or biomass, and biodiesel) and Hydrogen fuel (when produced with renewable processes).
What are the types of alternative fuels?
Some well-known alternative fuels include biodiesel, bioalcohol ( methanol , ethanol, butanol ), refuse-derived fuel, chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil, propane and other biomass sources.
What is the shelf life of avgas?
The short answer is that, under most conditions, the shelf life of avgas is about one year. If you are a commercial operator, this is the end of the discussion. For a private pilot, however, there are several points to consider. First, there is a large margin of safety in the one-year storage life of avgas.
Are biofuels a viable alternative?
Judging from the findings, biofuels just aren’t a viable option. A B20-fueled car releases 12% more CO2 per driven km than a gasoline car, and uses up 683 times more water (for agriculture and fuel production). E85-fueled vehicles would only release around half as much CO2 as a gasoline-powered car, but would also use up 655 times more water.
Is biofuel approved for use in commercial aviation?
The safety and performance of jet fuel used in passenger flights is certified by ASTM International. Biofuels were approved for commercial use after a multi-year technical review from aircraft makers, engine manufacturers and oil companies. Since then, some airlines have experimented with using biofuels on commercial flights.
