In this particular case, they are planning to take energy from carrier's nuclear power plant.
More generally, either hydrogen or fuel synthesis requires energy to come from somewhere; In this regard it is no different than re-building airplanes to use hydrogen, as the original article suggests.
The point is that we might have better chances synthesising fuels usable in existing planes, versus re-building majority of aviation to use hydrogen.
