Comparing Alternative Fuels For Cars

Norwegian scientists have drawn up a league table of alternative fuels for cars. Their analysis is based on a well-to-wheel approach that takes into account manufacturing, energy use, greenhouse gas emissions, and local and regional pollutants.

Bottom of the table, unsurprisingly, are petrol vehicles, but coming in a close second last are hybrid vehicles that can run on compressed natural gas or petrol. Top of their league are fuel cell powered vehicles using hydrogen gas obtained from natural gas methane.
