Hydrogen vs. Battery Electric Cars

In the end, hydrogen has reached its optimum. It cannot develop further because it is all about the chemistry of hydrogen. However, batteries can potentially be manufactured in new ways with different materials allowing faster charging, or more cycles. There is much more to come (probably). However, hydrogen is very promising for some aspects of energy storage, and almost certainly for some forms of bulk transport, most probably cargo ships and possibly planes. Ultimately though, economics will decide most of these questions.
