Even a BIG compressor would be 'small'.  There's not enough cu ft available
to run mobile engines, so they compress the NG to LNG (Liquified Natural
Gas).  IIRC that takes about 4,500 PSI, and needs discharge cooling around
-170 degrees to start the condensation to a liquid.

The process is very similar to LOX, Liquid Hydrogen, and Liquid Nitrogen.

Easy to understand why LPG has such a lead...


     Good luck...  M.
