Transport fuels are energy sources that power various means of transport, generally to power internal combustion engines. The transportation sector consists of road (including passenger cars, trucks and buses), rail, water, and air transport used for moving people and goods from one place to another[1]. The transportation sector accounts for around 20% of the global energyconsumption and is the biggest consumer of oil in the world ​[2].

Transport fuels are the result of refining processes that convert extracted energy resources into useable products. Liquid fuels vary based on the chemical characteristics of the primary fuel source. The absence or presence of certain carbon, nitrogen, hydrogen, and oxygen molecules determines the structure of the fuel source that liquid fuels are refinedfrom.  Sources of liquid fuels include petroleum, natural gas, biofuels, alcohols, hydrogen, ammonia, or even coal. The refining and distillation process of the various liquid fuels depends on the mixture of the fuel source being used.

80% of today’s transportation fuels are derived from petroleum.

Which includes:

Gasoline/Petrol

Diesel,

LPG (Liquefied Petroleum Gas)

Jet fuel

Marine fuel

Alternatives to fossil fuel based transport liquid fuels include:

Biofuels, which is biomassconverted into liquid fuels. The two most common types of biofuels in use today are ethanol and biodiesel. Ethanol is a type of alcohol, made by fermenting any biomass high in carbohydrates (e.g. sugars) through a process similar to beer brewing. Biodiesel is produced by combining alcohol (usually methanol) with vegetable oil, animal fat, or recycled cooking grease. It can also be used as an additive (normally 20%) to reduce vehicle emissions.
