The general idea is you can make methane that's equivalent to the methane that comes out of the ground, but in a carbon neutral way. So it's a benefit if you can give it someone who was going to burn methane anyways, like to run their natural gas furnace.
That's not as satisfying as just plain sequestering the carbon somehow. I mean, it would almost certainly be better to just run an extension cord to a neighbors house and let them run an electric space heater or heat pump off of the excess electricity.
Maybe methane could be used as an ingredient to make something else that's possible to store or bury long term, like some kind of plastic or liquid? (Most of what I know about the processing of hydrocarbons is probably wildly inaccurate because I learned it from Factorio.)
