What factors led to shift away from pursuing hydrogen-powered cars in favor of electric vehicles?
In: Other
It’s mostly about batteries becoming cheaper and electricity being more available / not needing to retrofit as much compared with hydrogen .
A hydrogen car is actually mostly an EV already, at least in the sense that it uses an electric motor to move the car. The main difference is where the power comes from – in an EV it’s a battery and in a hydrogen car it’s a fuel cell.
Hydrogen itself is still being looked at in cases where batteries don’t make sense. As an example, ships would be a more attractive use of hydrogen because batteries are still very expensive per unit energy and can be very dangerous if they catch fire. There’s also a very limited number of ports that the average shipping vessel ever docks at, so retrofitting wouldn’t be much of a problem either.
