Above its critical point, (-82.59°C) it won't condense into a liquid. It will continue compressing into a supercritical fluid, which will take a very high pressure to equal the density of liquid methane. The gas is about 0.7g/L at STP, the liquid is 422g/L at 1 atm at its boiling point. You'd need 600 atmospheres or 8862 PSI. A typical cylinder is around 2500-3000 psi. Liquid methane is distributed refrigerated.
