Hydrogen vs. Battery Electric Cars

Not sure about the data, would be nice to hear from a bev or Independant source for the comparison numbers.     
   Here in Canada the oil industry is investing in hydrogen to find a revenue source for their fossilized investments. I’m not counting on that as being remotely carbon free.  It’ll be brown or green washed hydrogen.
   Also, hydrogen train? Electric trains were a thing over a hundred years ago, the fastest in the world and the hardest pulling are overhead electric today. Rail companies could make the switch, but prefer to burn oil than invest in infrastructure.
