Hydrogen, like other "zero emission" vehicles have emissions, shifted to fixed power plants, in the case of Hydrogen, electric powered or more commonly natural gas reform plants create hydrogen with an about 60 percent efficiency, combined with the 60% efficiency of the current fuel cell technology gives about 36% power utilization efficiency, about the same as hybrid cars. Seems that a hybrid natural gas powered ICE car would give simpler results with smaller simpler tanks and no platinum fuel cell. Better yet if naturanl gas fuel cells currently used in fixed co-generation plants can be miniaturized for in car use, you would have a fuel cell car tat doesn't require the intermediate energy conversion step, yielding a net power effeciency loser to 60%.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
