»Hydrogen Engine Center Building Ammonia-Fueled System

Ammonia
ξ also known as anhydrous ammonia
ξ the agricultural industry has relied on as a fertilizer for many years
ξ contains no carbon
ξ stores like propane
ξ is the second most prevalent chemical in the world
ξ contains more hydrogen per cubic foot than liquid H2
ξ considered the “other hydrogen”
ξ an infrastructure for ammonia is already in place, as transporting and storing the fuel is much like that of propane
ξ usage and safety regulations for ammonia are already in place
ξ the process of obtaining a permit to use ammonia is usually relatively simple
ξ ammonia pipelines can be found in many areas of the United States, including Iowa, and distribution of the fuel is already established

HEC
ξ has established an Oxx Power engine line-up capable of running on a multitude of fuels, including hydrogen
ξ sees the decision to design ammonia-fueled engines the next logical step
ξ work on ammonia-fueled combustion engines goes back at least to 1967 with some demonstrations of spark- and compression-ignited ammonia-fueled engines by the US Army

Advanced internal combustion engines by Sandia National Laboratories
ξ the combustion of ammonia exhibits ideal Otto cycle performance in our free piston combustion experiment
ξ produces conversion efficiencies comparable to hydrogen
ξ ammonia is comparable to gasoline as a fuel for combustion engines
ξ three gallons of ammonia is equivalent to one gallon of gasoline in energy content
ξ 2.35 pounds of ammonia is equivalent to one pound of gasoline in energy content
