Natural gas is increasingly being shipped on the oceans:

When used as a portable fuel it is usually just compressed.

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:

Generally, it hasn't been very economical to do so, although I wonder what the numbers are now that we've got so much natural gas production in the US.
