Alcohol fuels are gaining increased attention. A move to alcohol fuels would reduce vehicular emissions of hydrocarbon and greenhouse gases and could lessen the dependence on the fossil energy sources. Yet, it also threatens the quality of life.

A number of factors account for the rapid emergence of hydrogen as a high priority fuel, gaining new prominence.
