Heavy trucks will eventually run on hydrogen. Hydrogen refuels like gas or diesel in a short amount of time. And the energy density of hydrogen per unit weight is many times that of lithium batteries.

The problem of the connector freezing up has yet to be solved. Back to back refueling is not the same as petrol.
Hydrogen at 10,000+ psi is a very difficult (expensive) material to handle. Current cost is about $15 / gallon equivalent. Good luck with that.
