1. A method for a carbon neutral cycle of a natural gas production, the method comprising:generating electricity with a molten salt reactor configured to generate zero carbon dioxide (CO2) emissions;powering a desalination unit with the electricity from the molten salt reactor,producing desalinated water (H2O) with the desalination unit;producing hydrogen (H2) and oxygen (O2) from the desalinated water (H2O) with an electrolysis unit;introducing the hydrogen produced by the electrolysis unit to a catalytic hydrogenation unit;reacting captured CO2 and the hydrogen generated from the desalination unit by catalytic hydrogenation in a catalytic hydrogenation unit, wherein the reaction produces a hydrocarbon fuel;introducing the hydrocarbon fuel into an oxy-combustion unit;producing CO2 in the oxy-combustion unit by reacting the hydrocarbon fuel with the oxygen from the electrolysis unit;capturing CO2 from the oxy-combustion unit; andintroducing the captured CO2 to the catalytic hydrogenation unit. 2. The method of claim 1, wherein the hydrocarbon fuel comprises methane. 3. The method of claim 1, wherein the hydrocarbon fuel comprises methanol. 4. The method of claim 1, wherein the desalination unit produces a high salinity product, the method further comprising using the high salinity product in an enhanced oil recovery process. 5. The method of claim 1, further comprising capturing CO2 sequestered from a natural gas production unit and/or capturing CO2 from a raw or partially processed natural gas stream and combining it with the captured CO2. 6. The method of claim 1, further comprising outputting at least a portion of the hydrogen produced by the electrolysis unit to a refinery and/or a hydrogen capture system for recovering the hydrogen as a product. 7. The method of claim 1, further comprising outputting at least a portion of the hydrocarbon fuel produced by the catalytic hydrogenation unit as a product. 8. The method of claim 1, further comprising feeding a portion of the hydrocarbon fuel to a downstream conversion process.
