Electrolysis can actually be done at above 70% efficiency. 80% efficiency methods are available. You unfortunately lose some additional energy when compressing the Hydrogen for storage, or when you turn it into Methane for storage.

- dredmorbius 5y agoThanks. Carbon capture is also possible at low energy cost, from seawater, as described in a set of research articles published by the USNRL through the 2010s. The Google X Project "Foghorn" failed to develop this in an economically feasible manner, but my view is that that's more a measure of the mis-pricing of fossil fuels than of the method itself. The resulting liquid hydrocabons are largely perfect analogues of petrol, kerosene (jet fuel) or deisel, and require no compression or refrigeration.
