Mark, are you sure it's "Less efficient to use H2 for stationary electricity due to far more conversion losses"? Modern power-to-gas is 63% efficient round-trip. Thats nothing like pumped hydro's 85%, but it can be centralized because there are already multiple unused pipelines..

Efficiencies of H2 system for producing electricity: electrolyzer (0.74); compressor (0.90); leakage (0.99); fuel cell (0.5-0.7); latent heat loss in water vapor (0.846) = 0.28 to 0.39 versus battery of 0.8 to 0.9 (with most of the lass during charging).

Also, I'd like to see a comparison of capex for batteries versus power-to-methane. And the externalities of converting natural gas plants to carbon-neutral storage?

Methanol isn't the same as methenated flue CO2, which is just methane. @bobwyman knows more about methanol than I do. The George Olah CO2 recycling plant in Iceland makes 2-5 million liters of methanol transportation fuel per year from the Svartsengi Power Station's exhaust.
