That's synthetic fuel. Although it costs energy to produce, it is nevertheless good for filling in a gap in renewable-energy development. Renewable and alternative sources are mostly adapted for producing electricity, and that has limitations. It is mostly good for stationary customers, and the most successful electric vehicles have been electric trains. However, they cheat by getting electricity from extra rails or overhead cables. Electric trolleybuses are similar, getting electricity from pairs of overhead cables. Battery-powered vehicles have been very limited for a long time, until recent years with lithium-ion batteries for electric cars. But even those are limited -- they are not very suitable for seagoing or aerial vehicles. Synfuels will be good for powering ships and airplanes, because it is hard to compete with liquid hydrocarbon fuels for energy density and convenience.
