Thanks.

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.
