At least 40 years ago my old utility had a compressed natural gas program for city buses. Must have eventually been successful as cng for city busses is pretty widespread now. Look for the raised roof on busses to hide tanks and cng label on back. We had mined limestone caverns for propane storage to create synthetic natural gas for winter peaking. Used compress air and vaporized propane blended to a 1000btu content and injected directly into gas main. Also had a crazy program to make liquified natural gas LNG and actually had a few cars with LNG tanks in the trunk. Dangerous cause the stuff had to be stored at liquified temps and constantly boiled off. Couldn't park inside or smoke. LNG is how nat. gas is now transported world wide in tankers. As a young gas engineer I worked on both programs. Pretty exciting stuff back in the day
