No single technology will triumph in the pursuit of a "greener" auto industry. Instead, the future will include a mix of cars powered by electricity, hydrogen fuel cells and biofuels, according to the world's biggest car makers. Gathered together at a hydrogen and fuel cells conference in Vancouver this week, car company executives said it is wrong to characterize their search for the low- or no-pollution vehicles of tomorrow as a battleground of technologies. "This is nonsense. This is not about picking some winner," said Andreas Truckenbrodt, chief executive of Automotive Fuel Cell Cooperation (AFCC), a company set up by Daimler AG and Ford Motor Co to research fuel cells for vehicles. "All these technologies have their value," he said, painting a picture of an auto industry in which combustion engines will share the road with plug-in electric vehicles and cars running on hydrogen. |
