It seems like the hybrid systems are becoming quite popular, apparently they don't need too large batteries nor very fast charging systems, but they save quite a bit of the cost for wires. I'd never heard about using only catenary on the uphill sections, but it's pretty ingenious. Also Prague having a large tram network probably means that they just use the same electrical system of the trams for the trolleys.
btw according to trolleymotion there's 299 operating trolleybus systems in the world, Prague would be the 300th.
