The problem here is that although the chemistry is sound, the economics are more questionable. Even with this breakthrough, the end methane looks orders of magnitude more expensive than the wholesale price of existing methane. Still, economies of scale are a real thing, and there are lots of use cases for this where it doesn't have to compete with the wholesale price of methane, for example in very remote locations far away from gas pipes or as grid storage options for solar power.
