Moz,
Thanks very interesting read …… one of my points is explained better in the BELOW section.
i.e … compressed natural gas is compressed into a high-pressure cylinder, usually to around 250 bar
……1 bar = 100KPA ... Which therefore 250bar would = 25000KPA
In order to achieve this by having a filling facility in a domestic environment - which is currently supplied between 1.3 – 3kpa. The gas act here in Australia, would need to change and the owner of the vehicle would also need to install a pumping station at home (very expensive to do so).
OR... be reliant on Natural gas service stations with compressed pumping facilities – only a one or two here in Brisbane - one which was being tested for the taxi market (which didn’t really have a good outcome) and the others being used at the City Council bus depot’s… which have managed to transition into this practice as it does become more viable for large fleets to cover the capital set up costs needed.
No doubt though, as time goes by this technology will become more viable with further improvements here in OZ, but I still think it’s a long way off yet….mind you, it will come quicker if the demand is there, like anything I guess !!
Vehicle Fuel Storage(Extracted from that site link you sent)
Fuel is most commonly stored on board vehicles in high pressure cylinders as compressed natural gas (CNG). As the name suggests, compressed natural gas is compressed into a high-pressure cylinder, usually to around 250 bar (or lower in some areas).
Emerging methods of storage include Liquefied Natural Gas (LNG), which is already in commercial operation and Adsorbed Natural Gas (ANG), which is still in the developmental stage.

CNG Cylinders
Compressed natural gas (CNG) cylinders are available in a number of different types, weights and sizes to suit different applications. As a general rule, as cylinder weight decreases, cylinder costs increase. In some cases, cylinders are available for lease from vehicle converters or gas suppliers. Details of cylinder suppliers can be found in our Business Directory (see left).
Additional information can also be found in our Guidelines for the Handling of CNG Cylinders document.
