Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.
So we’ve got “gas” in the US (short for “gasoline”), which is a liquid. There’s liquified petroleum gas (LPG), which is also a liquid. And there’s synthetic natural gas.
EDIT: Bonus: my understanding is that in Germany, an unqualified “gas” tends to refer to natural gas, which Germany is presently importing in liquid form (liquified natural gas, or LNG).
Petrol is a liquid. When liquid petrol evaporates is becomes a gas. When gaseous petrol is compressed in a container as pictured it becomes a liquid until it is released and allowed to expand again, hence liquefied (compressed) petroleum gas.

What’s wrong with LPG?

Capacity 20993… whats? I can only assume mL and it’s a forced perspective thing
Looking at the sign on the tank I am guessing this is USA and that would be gallons so it would be roughly 79,467 liters or 79,467,150 milliliters.
It does look like 20K gallons by the size of it. That is about half as big as the large semi tankers that deliver gasoline.
Yeah units are kinda important for this sort of stuff.
