Q1) Ordinary hydrogen is sometimes called a perfect fuel, because of its almost unlimited supply on Earth, and when it burns, harmless water is the product of the combustion. So why don't we abandon fission energy and fusion energy, not to mention fossil-fuel energy, and just use hydrogen?
A)The oil companies have lobbied the federal government to continue fossil fuel usage because it would mean huge profit losses for all the major oil conglomerates.
B)The conversion of current energy consuming vehicles and other machinery to hydrogen, although simple, is going to be very costly to the consumer and difficult to legislate.
C)The political, economic, and corporate pressures being exerted to oppose abandoning the other energy sources are the only obstacles to moving to the use of hydrogen as the nation's primary energy source.
D)Hydrogen represents a viable solution for stored energy but not as a general energy source since obtaining the hydrogen from water requires more energy than is produced when you burn it.
