LNG (liquiefied natural gas) is natural gas cooled to -161º so that it condenses and is converted into a liquid. This reduces its volume 600-fold compared to its gaseous state, creating storage capacity to provide excellent range.
Recommended for use with heavy vehicles.
CNG (compressed natural gas) is a colourless and highly flammable gas. It is lighter than air. CNG for commercial use contains a slight sulphur smell so that it can be detected.
Recommended for use with cars and small vans.
