| Natural gas doesn't compress as well or stay a liquid as easily as liquefied petroleum gas or LPG. The problem is to make storage of natural gas reasonable it has to be kept as a liquid because as a liquid you can store 600 times the volume in a canister vs keeping it as a vapor. To keep natural gas a liquid it has to be kept cool - really cool if I remember it's -256F, so you need an insulated tank and the liquid needs to be vented so it can boil and keep cool. Unless you are at a liquification plant where the vent gas can be recooled the vent gas is released to the atmosphere and you generally lose about 0.5% of the volume per day. LP gas is just an easier gas to deal with, that's why we have it everywhere. | |
