  1. True for consumer vehicles. But for long haul trasport and aviation, battery energy density is still not good enough. Hydrogen is only thing to replace fossil fuel in those applications.

  4.  @elinys2843  I'm not saying hydrogen is the answer. I'm just saying that current battery technology is not good enough. Hydrogen is one possible alternative. There could be others but we'll see. We must not be dogmatic and constraint choices only to electric. Be more open minded

  5. Not for consumer vehicles, but for long haul traports, marine and aviation, battery energy density is too low. Hydrogen is the only clean alternative to fossil fuel at this moment.
