>>LNG is in its infancy here, and is used mainly in buses and trucks, but with about the worlds largest reserves of LNG, I expect that will grow rapidly.<<
Here we go again. LNG or LPG? As stated before, to get natural gas to the liquid state requires a temperature of -265ºF. If a liquid at that temperature were put in a bus or truck, the pressure would rise as the temperature went up, and probably blow the gas tank. Physics states PV=nRT.

From Wikipedia
Liquefied natural gas or LNG is natural gas (predominantly methane, CH4) that has been converted to liquid form for ease of storage or transport. Liquefied natural gas takes up about 1/600th the volume of natural gas in the gaseous state. It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability, freezing and asphyxia.
The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure (maximum transport pressure set at around 25 kPa/3.6 psi) by cooling it to approximately −162 °C (−260 °F).
