The flexible electric car platform is innovative, but the fuel-cell version is freighted with hydrogen's flaws.
....swapping out the generator for a fuel cell may be a step backward. That is in part because producing the hydrogen needed to power the fuel-cell version could increase rather than decrease energy demand, and it may not make sense economically.
"The possibility that this vehicle would be built successfully as a commercial vehicle seems to me rather unlikely," says Joseph Romm, who managed energy-efficiency programs at the Department of Energy during the Clinton administration. "If you're going to the trouble of building a plug-in and therefore have an electric drive train and a battery capable of storing a charge, then you could have a cheap gasoline engine along with you, or an expensive fuel cell." Consumers will likely opt for the cheaper version, Romm notes.
