LPG is exported to Japan, South Korea, China etc for about one cent a litre. The producers could sell the gas here for a higher price as an automotive fuel.
Errrr, I think you're confused with LNG. However, why aren't we using LNG in our vehicles?
Yeah you are right, it's LNG that is exported on a huge scale, not LPG. However the same idea applies. Australia now imports both expensive petrol and expensive cars. Meanwhile we export cheap LNG and very few cars. It would have interesting if the Government had encouraged Australian car manufacturers to develop vehicles to run on LNG. We might have a viable and prosperous car and LNG automotive infrastructure industries if we had gone down this path. Local cars would have had a competitive advantage as they could run on cheap fuel. it's possible foreign companies may not have wanted to retrofit their cars to run on LNG plus retrofits are usually less reliable than OEM.
Meanwhile the ways things are going, there may not be a local car manufacturing industry here in the foreseeable future.
Hey, finally something I know a little bit about!
LNG does not compress at anywhere near the same ratio that LPG does. So it means that you need high pressure tanks, lots more volume, or both. I think they only way they can transport it overseas cost effectively is in specially designed tankers that lower temperature (a lot) in order to get sufficient volume.
AGL ran some trials, which must have been at least 10 years ago. I think they found that the range was very small, and unless there were enough filling stations around, it would never be viable. They even flirted with compressor/refilling stations that could be used in your home.
I think AGL even ran their own vans on it as part of the trial.
I think in reality, if you had a range requirement of 100kms a day, it would be worthwhile. I suspect that you should still be able to do it, as long as you have your own equipment.
Of course, without an easy way to get excise from it, because you could refill at home, I am not sure the government would be too keen on rolling this out. I guess you could somehow have sealed meters in the compressor and then pay a tax on that volume though.
