  3. When comparing emissions, you have to also look at Oxides of Nitrogen produced by all internal combustion engines using air as an oxidiser, due to the high temperatures and pressures of the combustion process. These are very damaging to human health.

  5. ​ @baldok14 Hydrogen is starting at a 2.5 to 1 disadvantage compared to batteries or other similarly efficient forms of energy storage. Hydrogen is rubbish in terms of efficiency in comparison.

  10. ​ @wilsonvinas5906 even less efficiently than using a fuel cell!
