Because of the depletion of fossil fuels and because of the growing adverse impact on the environment caused by the utilization of fossil fuels, researchers are investigating fuels which are renewable and which are environmentally compatible. In order to compare the fuel candidates, criteria have been developed, which make it possible to rank them in order of merit. Among all the fuels considered, hydrogen stands out as the best. The paper compares hydrogen with other conventional and unconventional fuels, and comes to the conclusion that in every count hydrogen has the best characteristics with many unique and desirable properties.
