Methane consuming bacteria could be the future of fuel 2019 May 09 Phys.org
Methanotrophs use a copper based catalyst to oxidize methane. This opens the possibility of producing liquid transportation fuels from methane without great expense.

Problem with using living things for making fuel is they have a lot of upkeep. They are concerned with living, not making fuel for us.
So efficiency and output is generally just low.
Inanimate is the way to go. A catalyst bed just does one thing. It has no upkeep.

It is the discovery of the catalyst that is of interest.

If you're starting from methane you're either using biogas or natural gas. There's a fair energy hit going from CH4 to MeOH; you go from 891 kJ/mol down to 726 kJ/mol, a loss of about 20%. The only real plus to doing this is if you have methane that you can't ship and need to turn it to a liquid, or need it for e.g. pipeline antifreeze. I sort of recall seeing a scheme using enzymes which converted CO2 to MeOH essentially by reversing the normal metabolic process, feeding it with NADP+ or something of the sort. I'm not sure how you'd make the NADP+.

Gold solution to catalysis grand challenge Cardiff University 06 Jan 2022 Phys.org phys.org/news/2022-01-gold-solution-catalysis-grand.htmlReputedly, zeolite with gold nanoparticles can convert methane to methanol simply and inexpensively. Acetic acid, an important industrial chemical, can also be produced.
