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.
