ABSTRACT
Hydrogen is considered one of the most promising fuels for generalized use in the future, mainly because it is an energy-efcient, low-polluting, and renewable fuel. Hydrogen is versatile and clean, and with environmental benets in mind, the production of hydrogen from renewable energy sources such as biomass, wind, solar, and nuclear sources is under consideration [2-3]. Yet, discussion of potential problems that widespread use of hydrogen might bring, as with whale oil and petroleum before it, is lacking. The identication and control of potential adverse consequences is an ethical requirement whenever any new technology is introduced, and certainly in the case of hydrogen, with such world-in—uencing potential [1].
