Yes, it's just rearranging molecules.

Finding the right catalysts to convert a gas to a solid (or liquid) and back, with low energy loss, is a more elegant, cost effective, and safer solution.

I would think a liquid would be preferable for transport, but the low cost conversion break throughs seem to be gas to solid. Qatar is providing most of the funding for the best publicized project, in addition to their immeadiate range LNG projects.

Here's a couple of references of one of the many projects working on gas to solid for transport. In this case as a hydrate.

Not only it could increase sources of production, it is cheaper to carry solids than liquids. And it's also cheaper to produce because of reduced cooling costs.

The company's demonstration plant produces as much as 600 kilograms of hydrates per day, moving the methane through all the necessary phases: hydrate formation, storage, pelletizing, and "controlled dissociation," or separation of the gas and water. Whereas a liquid natural gas facility requires temperatures of -162 ºC, Mitsui's plant operates at -10 ºC, which means huge savings in cooling costs.

This gas-to-solid process is also safer because of reduced risks of ignition.
