Nearly all warehouse forklifts run on LPG or CNG and when I lived in South Korea - lots of small commercial trucks use LPG as well.

Another relatively unknown fact about CNG is its high octane rating. Compare CNG's octane rating of 130 to what is posted on the pumps at your local gasoline station. IF the infrastructure was in place, at least in urban areas, vehicles powered solely by CNG could be used for work commutes and grocery getting. The limit of their usage would be their range. Home refueling stations are also a factor. With an octane rating of 130, purpose-built engines could be made smaller and thus lighter than a gasoline engine producing the same power. The weight loss would offset some of the weight of the CNG tank(s) Then again there would be no gasoline tank. A dual-fueled engine (gasoline and CNG) could also be made smaller by using CNG to supplement the gasoline's octane as required. Most of the time the engine would run on gasoline (cruising and idling) but use CNG as an octane supplement or booster when more power, as in accelerating, was required. Again the engine could be made smaller and lighter to produce the same power, but not to the same extent as a pure CNG fueled engine. In the future hybrid designs could incorporate gasoline, CNG, and electricity. Programming the computer system to simultaneously control all three plus the ignition and valve timing and perhaps the compression ratio would be a nightmare, but it will get sorted out eventually. Id P.S. I once rode in a '76 Thunderbird that was dual fueled... gasoline and CNG. One or the other... but not both simultaneously.
