Here's a scheme that would ameliorate the problem even if lead-acid batteries had to be used. Cars powered by liquid hydrogen have the potential of matching the performance of gasoline powered vehicles. The hydrogen tanks will need three times the internal volume of gasoline tanks and still greater external size because of the insulation required. Schemes for using hydrogen in other forms than liquid are unlikely to have the required range. See the page on hydrogen for more details.
Some people seem to believe that using hydrogen gets more energy.
It only provides a way of using nuclear or solar energy. Rather than putting all the effort into reducing carbon emissions, it may be more cost-effective to put some effort into removing more CO 2 from the atmosphere. What will surely work is to cut down forests, not burn the wood and replant the forests with fast growing trees. When these trees reach a size at which their growth slows, they would be cut again. Back in the carboniferous era, trees fell into swamps which evidently provided a reducing environment.
