Your chart is not entirely accurate. First of all you only consider compression and liquefaction for hydrogen storage methods and you don't mention metal hydride storage which is the most efficient form of hydrogen storage. Secondly, you assume that a lot of energy will be wasted in transporting the hydrogen, but what if I use an electrolyzer powered by a solar panel on my roof to produce the hydrogen for my vehicle, then there would be no energy wasted in transporting the hydrogen.
