Hydrogen fuel cells
Daimler invests in hydrogen-powered cars and Royal-Dutch shell announces it will build 1,000 hydrogen fuel stations in Germany by 2015. But, how much do they reduce the carbon-footprint? The article notes:
"The central problem is to produce hydrogen in a way that doesn't cancel out the environmental gains. Most hydrogen available today is refined from natural gas. Deployed in a fuel-cell car, such hydrogen cuts CO2 emissions 30% more than a diesel engine-significant, but hardly revolutionary."
