I can see ethanol getting used for planes and trucks, as its energy density per weight (contemplating the full system; fuel, tank, lines, engine) is not far off the current systems.
Neither batteries nor hydrogen comes near.
Planes have the advantage of only using airports and generally fixed routes so the fueling infrastructure could be set up relatively easy, but planes have very limited considering the extra space and weight the system would have.
Trucks are less limited on weight and space but need to go anywhere.
Batteries would be out of the question, except for short range (city) delivery trucks if they can get charged where they get loaded in - especially if 'emission free' zones are going to be a thing.
