The main pollution from carbon-based fuel is carbon dioxide, also called CO2, which is the product of burning a hydrocarbon fuel like coal, oil or gas, with oxygen taken from the air. Uniting carbon with oxygen produces CO2, and releases energy as heat which is used to drive a heat-engine (a gasoline or diesel engine or a gas turbine, or a steam turbine for which the fuel is used to produce steam from water as an intermediary).
Among the carbon fuels, gas is said to be less polluting because the atom is lighter and thus less CO2 is produced for a given amount of energy output.
Hydrogen is less polluting as a fuel because its product, after burning with oxygen, is only water vapour, which is a greenhouse gas but excess water vapour falls as rain. However hydrogen is mainly produced from water in which the hydrogen and oxygen are separated by adding energy by electrolysis. Thus hydrogen is only a means of storing energy because the same energy is then released by the burning process.
What else can I help you with?
Which fossil fuel is the least polluting?
Natural gas releases less carbon dioxide pollution when burnt than either coal or oil.
What type of fuel is most polluting?
diesel
Which cooking fuel is less polluting?
A form of cooking that has the less causes of pollution would be ... sun cooking ... that's when you put your food on a pan and let the sun beat down on it and cook it ...
The least polluting fuel for vehicles?
bio-diesel
Does jet fuel cause pollution?
Jet fuel is capable of polluting, just as gasoline is.
What is the least expensive mode of transportation?
The least expensive mode of transportation is by water. It is fuel efficient, less polluting and the safest. It is also the least expensive to move cargo.
Are orangutans dying out from pollution?
Yes people are polluting their water with oil or fuel
What are CNG compressors and where do they use?
The term CNG stands for Compressed Natural Gas. This is compressed by special compressors for use in automobiles, household and other less-polluting substitute fuel applications in industry.
Why methane butane liquid alcohol are less polluting?
Because they are pure
Why is it called renewable energy and how does it differ from fossil fuel energy sources?
Renewable energy means that this type of energy will never get exhausted. There will be enough for all generations. It differs from fossil fuel energy resources becaus it is less polluting and easily available in a large quantity
How can hydrogen be used as fuel for cars?
it can be used by not polluting the air and it is a safe gas for cars and the environment
