Semi's, and other large fleet vehicles will go Hydrogen because it makes the most sense. Quick refueling and turn around.
The vast majority of people will be using an electric vehicle.
Hydrogen is currently a really expensive fuel source, and if everyone else is using battery based vehicles, you'll never get the infrastructure in place to refuel with hydrogen, except maybe for things like ships.
There should be some additional focus on industrial emissions as those are larger than all electrical grid and transportation (all modes/systems) combined. Super-hot intense heat is required by certain industries like forging steel or making cement. One solution is thermal batteries, which in part or in some cases has been called “hot rocks in a box”.
As for new forms of energy, nuclear fusion (unlike nuclear
fission). They’ve been working on this in the National Ignition Facility at the Lawrence Livermore National Laboratory, California.
The two most obvious fuels are sunlight & wind. They are also a renewable energy.
