Comparing Alternative Fuels For Cars

Science Daily — 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.

Karl Høyer of Oslo University College and Erling Holden of Western Norway Research Institute, Norway, and reported in Inderscience's International Journal of Alternative Propulsion their analysis of fuel chains including petrol, natural gas, and alternative fuel sources such as methanol and ethanol, hydrogen and biofuels.

"Alternative fuels are not in themselves a road towards sustainable mobility," the researchers say. However, their analysis places petrol and hybrid vehicles firmly at the bottom of the league table when all energy factors from source to consumer use are taken into account. "Any alternative fuel we considered is better than the cars that are used mostly today," they add.
