The nuclear fuel raw substances come from earth as like fossil fuels. The primary material of the fuel is uranium and the amount of power that comes from small uranium is what  makes nuclear power advantageous. The power from one kilogram of uranium is more or less equivalent to 100,000 kilograms of oil; consequently, as a function of power utilization, not much uranium needs to be removed from the ground, thereby the environmental impact of uranium mines is relatively less when weighed against mining and drilling for fossil fuels.

Nuclear power plants do not produce any environment problems by emitting carbon dioxide or sulphur, which are supposed to be major contributors to greenhouse effect likewise. Nuclear power plants stops 5.1 million heaps of sulfur dioxide, 2.4 million heaps of nitrogen oxide, and 164 million metric heaps of carbon from entering into the earth's environment each year, according to the Nuclear Energy Institute, U.S.

In 1958, The Ford Nucleon, a nuclear-powered concept car was developed by Ford Motor Company. The design did not comprise an internal-combustion engine, infact, the vehicle was to be motorized by a small nuclear reactor in the back of the vehicle. The vehicle also featured a power capsule balanced between twin booms at the rear. The copy of the car can be viewed at the Henry Ford Museum in Dearbor, Michigan

The most critical ecological concern faced by the nuclear industry is the matter of its waste clearance.

HCNG or H2CNG is a fusion of compressed natural gas and 4-9 percent hydrogen by energy. In short natural gas is blended with hydrogen to make HCNG. It is utilized as a fuel gas for home appliances and internal combustion engines. Flammability and leak risks are alike in this mixture as those of compressed natural gas and therefore no unusual precautionary measures are necessary so as to avert hydrogen embrittlement of the materials which makes contact with with the mixture.

Vehicles powered with HCNG fuel are stepping towards the upcoming hydrogen-based transportation. They lessen nitrogen oxides emissions and proffer instant emissions benefits and petroleum reinstatement. Simultaneously overlay the technique for conversion to fuel cell vehicles by constructing stipulation for hydrogen structure.

There are current researches made to conclude the advantages of hydrogen as a vehicle fuel. Earlier knowledge displays that utilization of hydrogen in an internal combustion engine either as a whole or combined with CNG is likely to offer payback in emissions-preservation and exhale more benefits than the vehicles powered by compressed natural gas.

Other studies have revealed that the use of a blend of hydrogen and compressed natural gas (HCNG) in a conformist spark instilled gaseous engine enlarges the lean limit, advances thermal competence and lessens emissions whereas direct insertion of gaseous fuels has been shown to widen the load range of engines.
