Actually, LNG requires cooling, not pressure. It is below the critical temperature of methane. It can not be compressed into liquid anywhere near ambient temperatures.
PV=znRT. Decrease temperature and you decrease pressure, at least so I have heard.
I’ll admit. I know very little about the LNG business.
