Reference

The key specification for EVs so far has been 'range'. But how are the numbers measured, will range specific match reality, and can the number even be compared?

It turns out there are even 3 different standards for measuring range, and they give very different answers!

Further, why have we moved from 'economy' to 'range'? Is there still even economy with EVs?

There is much talk of a 'hydrogen economy', but what is the substance behind it all? There are many myths but hydrogen can be :

  • 'green' hydrogen, not a source of energy, but a less efficient storage stepping stone on the path to battery power.
    • or
  • blue/grey hydrogen, the fossil fuel industries' hope for greenwashing emissions.

This exploration provides looks at the reality, and the myths about hydrogen, and provides background for other pages such as: Electric or Hydrogen Cars and Hydrogen Scams.
