Hydrogen Is Energy Carrier, Not Source

In “Hydrogen-Based Energy Merits Research” (Physics Today, Physics Today 0031-9228 56 10 2003 35  https://doi.org/10.1063/1.1628997 October 2003, page 35 ), reporter Jim Dawson has fallen into the same trap so many writers of hydrogen articles do. Hydrogen is not an energy source. It is a carrier of energy. For hydrogen to replace fossil fuels, extremely large-scale programs of solar power, wind power, fission, or fusion must be developed to produce it. This major factor is not mentioned in the article; in fact, it seems also to have been omitted in the Department of Energy report. Perhaps the Physics Today article should have brought that out.
