Weaning the Navy from Foreign Oil
By Donald Wilkins
Liquid hydrocarbon fuel is a convenient carrier of high-density energy and, despite research on hydrogen (H2) fuel, electric batteries, and other touted replacements, will likely remain the preferred fuel for transportation for the time being. Aviation and ship propulsion, where the low-energy densities of the proposed alternatives are completely unsatisfactory, will have an insatiable thirst for liquid hydrocarbons into the foreseeable future. At the same time, fuel costs are crimping already tight budgets, and costs are expected to continue to rise as demand increases and supplies tighten.
