Methane has a much lower boiling point (-182 C) than propane (-42 C), so liquefying methane (and keeping it liquid) is substantially harder.
Can you not simply roughly double the pressure you store it at? Or is LPG already stored at borderline risky pressures.
Vapor pressure is exponentially related to temperature; you really need to keep it cold.
If you really want to produce a liquid transportation fuel from methane, the usual approach is F-T synthesis:
