Hydrogen vs. Battery Electric Cars

Whoa, Dianna. You glossed over hydrogen production and distribution. Hydrogen is most cost-effectively derived from natural gas. We should only do electrolysis of hydrogen when there is an excess of wind or solar electricity, and that is not common. 

The electrical grid is mostly driven by natural gas and coal still. So when you do efficiency calculations for BEVs, you need to factor in the efficiency of the generating plants which range between about 40-60%. That takes BEVs from 70-90 down to 28-54%.
