On one hand, battery busses require lithium and rare earth metals which needs to be mined from a relatively short supply, as well as lots of fancy chemical processing which I’d wager produces plenty of byproducts, and batteries have a limited lifespan before needing to be replaced. On the other hand, trolley busses (the kind that gets power from overhead wires) require extensive infrastructure in the form of wires and poles, which require tons of metal (though much more abundant steel and aluminium) to produce and energy to install and maintain, and the wires also wear out from friction and also need to be replaced from time to time. Anyone know any papers comparing the sustainability of these two technologies? I’m also interested in how the wire-to-wheel energy efficiencies compare between them.
So you have all the expense/weight of needing a huge battery on the lorry. And you have all the expense/maintenance putting infrastructure along the highway.
It sounds like the worst of both worlds. I can’t think of any major advantage to this approach, that would make it worthwhile.
Not easier to just put charging stations on the highway?

I don’t have data. But I am sure it makes more sense to stop for lunch and plug your lorry into a proper 3 phase charger every few hours. The charging rate you’ll get from an overhead line, and the resistive ineffiencies, and the friction wear. It won’t make sense.
Hybrid is the right way, for all but the smallest vehicles.
