It would be far much efficient to supply the renewable power directly to the grid than create an intermediate fuel. However, this may be a way to store energy to make up for times when the availability of renewables is low in relation to demand from the grid. Even using this process to create liquid fuel for vehicles is very inefficient in comparison to using the power to charge a battery in an electric vehicle. But, liquid fuels are much more convenient for energy storage due to their much greater energy density than batteries.
