The following table gives a general outline of the main features of these.

1) LPG
2) CNG
3) LNG

1) widely distributed4
2) bulk shipments,motor vehicles
3) bulk shipments

3) fuel

Notes
(a). LNG tanks are designed to operate at a slight positive pressure.
(b). CNG is sometimes stored at cool temperatures, typically down to around -30°C.
(c). Methane is lighter than air at temperatures above about -100°C.4. LPG is widely used in domestic and industrial applications. LPG is transported by road tanker, and by rail, ship and pipeline. Domestic examples include bottles used on a BBQ or caravan.
