Hydrogen vs. Battery Electric Cars

Lots of comments to scroll though.  I think the biggest question most people have between all technologies (HEV, BEV, ICE) is cradle-to-grave impact.  Take into consideration mining for the minerals and disposal of battery fuel cells.  I'd love to understand the full energy usage comparison between HEV and BEV, then take a look at lifespan and disposal between the technologies.  Also, people must consider their energy source when using BEV.  If you live in an area where coal-fired power plants are still in use, your CO2 contribution is likely just as high as an ICE vehicle.
