Increasingly, with climate change a growing concern and governmental targets to decarbonise transport, cities are opting for electric buses rather than diesel. These buses carry batteries on board that need to be re-charged periodically, for which a number of different charging options exist.
Battery electric buses can be charged at plug-in stations or by using special wireless charging pads.
Another type of electric bus is the capacitor vehicle – a traction vehicle using supercapacitors to store electricity. These can be re-charged at bus stops under electric umbrellas.
Another area of charging infrastructure for buses includes the overhead wires that is used by trolleybuses.
One emerging technology for buses is the use of hydrogen fuel cells. This technology requires hydrogen refilling stations for buses.
