Fuels

Fuels are substances that serve as an energy source for vehicles and machinery. They enable combustion in engines, providing the power to drive them. The most common fuels are petrol and diesel, which are derived from fossil sources such as crude oil. However, these conventional fuels have a negative impact on the environment, as they contribute to air pollution and the greenhouse effect.
Here is some information about fuels and their environmentally friendly alternatives:

Petrol and diesel:

Petrol:

It is mainly used in spark-ignition engines and contains hydrocarbons. Combustion produces carbon dioxide (CO₂) and nitrogen oxides (NOₓ).

Diesel:

This fuel is used in diesel engines. It also produces CO₂ and NOₓ, as well as fine particulate matter.

Environmental impacts:

Greenhouse effect:

The combustion of petrol and diesel contributes to global warming by releasing CO₂.

Air pollution:

Nitrogen oxides and fine particulate matter impair air quality and human health.

Climate-friendly alternatives:

Electric mobility:

Electric cars use electricity as an energy source and produce no direct emissions. However, their environmental performance depends on how the electricity is generated.

Hydrogen:

Fuel cell vehicles use hydrogen as fuel. Its reaction with oxygen produces only water.

Biofuels:

These are produced from renewable raw materials such as vegetable oil, algae or waste. They are climate-neutral because they absorb the CO₂ that is released during their combustion.
Natural gas (CNG):
Natural gas is a cleaner alternative to petrol and diesel.
BioCNG and BioLNG,
which are derived from biomethane, are particularly environmentally friendly
The choice of fuel affects environmental performance. Climate-friendly alternatives are crucial to reducing CO₂ emissions in the transport sector and promoting sustainable mobility.
