Abstract

As conflict, the environment, and politics cause changes around the world, the United States Air Force is pursuing a diversification of drop-in and alternative fuel sources. Hydrogen fuel cells for vehicles are gaining popularity worldwide. Yet, how to best produce hydrogen gas still remains a question. This thesis will provide an overview of various hydrogen production methods and their respective environmental impacts, costs, efficiencies, and viability; and will perform sensitivity analysis to determine an optimal solution. The optimal production method is Thermolysis followed by Steam Reformation of Landfill or Natural Gas, Coal Gasification, and PEM Electrolysis. Based on varying requirements the recommended options for U.S. Air Force consideration are Thermolysis if nuclear power is available, Steam Reformation of Landfill Gas, and PEM Electrolysis. Steam Reformation of Natural Gas is only recommended for use in non-contested environments. PEM Electrolysis is extremely promising due to its portability and required inputs of only water and electricity.
