CNG (Compressed Natural Gas)

CNG is compressed methane with a small amount of ethane which is delivered in pressurised vessels at a delivery pressure up to 25 MPa (250 bar), a similar pressure to that used in air diving scuba tanks. CNG is used already in many city buses. CNG is relatively easy to package, requiring only a compressor and dispensing system. It is expensive to transport due to the cost and weight of the pressure vessels and the relatively low energy density of the compressed gas. CNG is best suited to shorter delivery runs where pressure vessels can be refilled at least daily.


Orbit provides a complete CNG solution. By offering customers depressurised gas at their  site, Orbit looks after all of the issues associated with the gas purchase, compression, transportation, storage and pressure letdown.

Micro LNG (Liquefied Natural Gas)

LNG is liquefied methane delivered as a cryogenic liquid. Methane liquefies at -162 degrees C. LNG has a similar energy content per tonne to diesel. However it requires a volume approximately twice that of diesel for an equivalent amount of energy.

Orbit is working with partners to offer modularised small scale LNG plants which can be installed at strategic locations primarily to fuel mining and trucking fleets. Where there is a gas pipeline to the minesite the cost of LNG  will be significantly lower than diesel.

Orbit's long term goal is to establish a large scale LNG distribution network allowing Australia to replace up to $6 billion of its current $16 billion diesel demand with LNG. To be successful, Orbit will aggregate demand, develop key distribution nodes and source LNG. Orbit's LNG will come from existing large scale plants or its own mini LNG plants.
