Fuel cell powered automobiles are a more complex discussion than this article presents. For example, hydrogen is not carbon emission free if it is generated from fossil fuels (which contain carbon). Only if it is generated by renewable energy is it genuinely carbon free; however, electric cars \"fueled\" by renewable (e.g., wind) energy could offer a nearer-term solution, and probably at lower expense, for at least some automotive niches.

That said, I am glad Honda is committed to doing something *now*, while taking a \"long view\" about making fuel cells a viable powerplant for the future.
