Batteries already hit the wall with trucks; otherwise the industry would be all over them. It's highly more likely that hydrogen infrastructure could be built out faster than battery technology could improve for batteries to be effective for trucking. Hydrogen's biggest benefit is you can quickly tank your vehicle up on energy - as fast as with liquid fuel. Also hydrogen fuel cells haven even less maintenance than battery powered EVs, and while fuel cells do require some maintenance they don't require wholesale replacement like battery packs do. Batteries degrade even faster when under heavy use - and freight puts big demands on a drivetrain. And for those proposing battery swapping - where you going to get the batteries from? We can barely keep up with EV car demand and EVs are far from ubiquitous. These are serious issues: batteries just don't scale - on multiple fronts.
