>"Hydrogen + fuel cell systems to achieve the same energy density require very costly extremely high pressure tanks and fueling systems, and that is before you get into the argument of whether hydrogen is a terrible use of energy." The main problem here is you are comparing it to a fuel source which took million of years to form naturally. Think of the energy expenditure behind that!
