Or maybe for inland barges have some medium sized batteries, recharged at each lock, where you already have infrastructure, possibly with pantograph. There are already a bunch of these type of projects for buses with quick charge at multiple bus stops across their routes.
No need to install thousand of miles of pantographe cables above every canal. If the locks are too far, you can install the overhead lines every 10s of miles, on long straight with clear rules of passing.
