   One measure of alternative fuels in the U.S. is the "gasoline-equivalent gallon" (GEG). In 2002, the U.S. used as motor fuel, ethanol equal to 137,000 terajoules (3.8 × 10 10 kWh), the energy equivalent of 1.13 billion US gallons (4.3 gigalitres) of gasoline. This was less than 1% of the total fuel used that year. [5]

   The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.

5. Hydrogen internal combustion engine vehicle - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_internal...

   Emissions from burning hydrogen can be negligible but emissions from producing hydrogen are currently higher than direct combustion of the source. [37] Hydrogen has a wide flammability range (3–70% H 2 in air) in comparison with other fuels. [35] As a result, it can be combusted in an internal combustion engine over a wide range of fuel-air ...
