A lower temperature catalyst for methane is a big breakthrough. However, storage of methane is a problem because it requires high pressures to get adequate amounts on board a vehicle. A better solution would be a (relatively) low temperature catalyst for propane, because propane readily liquifies at moderate pressures, solving the storage issues with methane and hydrogen.

Of course, the percentage of energy derived from carbon is higher in propane than methane, but it is much less than that in gasoline. There is also much less propane than methane in gas and oil wells.
