Sorry about the long Subject line. It seems necessary, nowadays, to say up-front that a topic is trying to inform, not brow-beat.

&ssDocName=NCC043722&ssSourceNodeId=&ssTargetNodeId=3018 is an item on a study, conducted by Norfolk County Council (ie, in the UK), into relative advantages of a range of alternative fuels and fuelling systems for vehicles. Some results are not as some advocates would wish; others are.Points to note: (1) they conclude that often one must suit a fuel system to local circumstances; (2) these folk have no special axe to grind -- they want to find the _good_ arrangements.
FWIW Norfolk is the fourth largest English county, with scattered population centres, and the council do a LOT of driving in sundry kinds of vehicles. (Scotland's counties tend to be larger and a bit hillier than England's.)
