Such a thing doesn't yet exist.

Please explain further. In my book a trolleybus IS zero polluting.

Your book is - at best - skimpy.

Where does the electricity come from?

As a former CEGB / NGC employer I can answer that question in exceptional
detail. In can see where you are coming from by suggesting that the
production of electricity is sometimes less than enviromental friendly but
equally can be derived from renewable sources such as wind power or hydro
sources. The power might even have been provided from another country but
however it was produced, and where ever it originated from, the product does
not come with any kind of labelling for your average user to be able to
determine its source.

The right combination of circumstances can therefore have a trolleybus
operating on a fuel that can be considered to be entirely zero polluting and
to suggest that can't happen is bunkum. In any event I would certainly prefer
a trolleybus service running past my front, especially at night, rather than
the cleanest of diesel buses.
