If you convert methane to methanol, it can be mixed with gasoline and run in flexible fuel vehicles so there is easy integration into the fuel mix. You don't need a truly "special" car with special fuel needs. Also, methanol is safer to transport than LNG. So you get a flexibility and safety advantage.

Currently, methanol is produced from fossil resources, but eventually it would be produced using nuclear and other non-fossil energy sources.
