Despite being the most abundant element in the Universe, hydrogen does not exist on its own so needs to be extracted from water via electrolysis or separated from carbon fossil fuels. Both of these processes require a significant amount of energy to achieve. This energy can be more than that gained from the hydrogen itself as well as being expensive. In addition, this extraction typically requires the use of fossil fuels, which undermines the green credentials of hydrogen."

Those who claim that hydrogen is the future of fuels for: "trains, planes and automobiles" do not know physics and chemistry.
But battery power will be, right. How you going to run a bulldozer, combine, ship, transcontinental aircraft, etc ? If you say they can overcome the engineering obstacles, then they can just as likely overcome the hydrogen engineering obstacles. You could use the new safer nuclear options to get hydrogen. Batteries require destroying the environment for heavy minerals for their construction and environmental problems for their disposal.
