Hydrogen utilization and alternatives

Abstract

The historical uses of hydrogen are described along with potential new uses which could develop as a result of the diminishing supply of conventional fossil fuels such as natural gas. A perspective view of hydrogen, both as a chemical feedstock and as a fuel, is necessary to understand its relationship to the overall national energy projections. These projections, which show energy usage in terms of use sectors, forms of energy, and sources of energy, do not specifically identify hydrogen as a component of the energy system. By superimposing the traditional roles upon the new opportunities for hydrogen on the energy projections, the role of hydrogen and future projections is developed within the context of the national energy projections. Use, supply, and other factors affecting application are interrelated and are discussed.
