Like it or not, batteries figure in mightily with the future of electric or FC vehicles.
Tesla is expecting to sell 500,000 cars per year by 2020. They are planning to build a $5 billion lithium battery facility in the southwest that will be partially powered by solar and wind and to be completed by 2017. It is expected to produce the next generation of lithium batteries that should boost battery power density by ~10% and lower the price of a Tesla to ~$45,000 (~30% reduction).
There are about 350,000 electric/hybrid vehicles on the road today and another 350,000 will be added in 2014 alone. The big boost in electric vehicles is due in no small measure to the electrical charging infrastructure already in place. FC vehicles are expected to have a 1-4%, about a tenth of electrical/hybrid market penetration by 2020, but a great deal depends of the cost and fueling infrastructure going forward.
FC proponents should laud the rapid increase in EV growth as it directly affects the ability for FC vehicle growth.
