Four mobile powertrain developments compared with the gasoline internal combustion engine for well-to-wheel efficiencies, CO2 emissions, and investment costs. Although the ICE has lowest investment cost, it is not competitive in well-to-wheel efficiency, and worse than the alternatives for CO2 emissions. The hybrid diesel has the highest well-to-wheel efficiency (30%), but well-to-wheel CO2 emissions are similar to the fuel cell using compressed hydrogen produced on a centralized petrochemical basis. The latter case has the advantage over the hybrid diesel in that CO2 emissions are concentrated and easier to control. Only on-board reforming of methanol offers the possibility of using a renewable energy source (biomass). This is an abstract of an article originally published in J. of Power Sources 102(1/2) 205-209 (1 December 2001).
