Before reading the following, I would have said, "You can't get there form here." Note that this process is endothermic, and requires the input of a great deal of energy, and the source of that energy is not described.
From Wikipedia:
"The Sabatier reaction or Sabatier process involves the reaction of hydrogen with carbon dioxide at elevated temperatures and pressures in the presence of a nickel catalyst to produce methane and water. Optionally ruthenium on alumina makes a more efficient catalyst. It is described by the following reaction:
CO2 + 4H2 â CH4 + 2H2O"

Usually hydrogen gas is produced industrially by hydrating methane according to equation:
CH4 + H2O > CO2 + H2
This 'might' be ideal in producing hydrogen as fuel.However, the reverse reaction is able to produce methane according to equation:
H2 + CO2 > CH4 + H2O
