A thorough evaluation of each potential alternative fuel against the ideal fuel criteria listed, leads to the choice of NH3 (anhydrous ammonia) as the leading alternative fuel candidate. NH3 has been called “the other hydrogen” and exhibits all of the advantages of hydrogen.
The knock and rough limit crossover occurs at ~13.5:1 for E85 and ~12:1 for gasoline. E85/NH3 has higher knock limit and allows for a higher maximum compression ratio and thermal efficiency. Gasoline/NH3 has a lower roughness limit and allows for a slightly more fuel mixture flexibility.
LNG has around 40 % lower volumetric energy density than diesel, roughly the same as LPG. When accounting for the storage system, LNG has roughly 1/3 the volumetric energy density as diesel. Liquid hydrogen, ammonia and methanol have even lower volumetric energy density – around 40-50 % of LNG.

Ammonia is a carbon-free fuel, so it has potential to reduce carbon dioxide emission from power plants when used as a fuel. However, combustion characteristics of ammonia are notably different from hydrocarbon fuels, especially regarding NOx emission [1].
NH3 is safer than propane and as safe as gasoline when used as a transportation fuel. The Iowa Energy Center funded a comparative quantitative risk assessment (CQRA) study completed March 2009, by Quest Consultants Inc., Norman, Oklahoma. “Comparative Quantitative Risk Analysis of Motor Gasoline, LPG, and
