The van was refuelled at the comhairle's H2seed Facility
A hydrogen-powered Royal Mail van has been tested on the Western Isles using fuel from a facility run by the islands council.
The vehicle ran regular delivery routes on Lewis between June and August.
It used fuel from Comhairle nan Eilean Siar's hydrogen production, storage and fuelling station called the H2seed Facility.
The project will be discussed at a conference on hydrogen power in Edinburgh later this week.
