I think methane generation for storage purposes has a place in going towards zero CO2. methane is relatively easy to store - currently Germany has reserve of 90 days of methane - and it can be very easily used in gas power plants. If they are combined electric and heating power plants, their efficiently is really good. In total, the energy losses are higher than with batteries and pumped water storage, but the relative cheap long-term storage of the methane will make this attractive.
