Not really sure to be honest.
I know VW (the worlds largest carmaker) and BMW have agreement with Bosch, being German companies I suppose that is to be expected. As car battery weight/performance is improving at a rate of 7% each year, it is reasonable to suspect this list will grow. At that rate, electric vehicles will be about the same weight as a petrol powered car (full tank) weighs in the next few years.
VW alone are investing billions of Euros into electric vehicle and hybrids with all new plants in China being built exclusively for this market. They are projecting sales of well over a million vehicles once the plants are completed.
Electric vehicle sales still only represent a couple of percent of the total car market, but this sector is growing at a rate of 40% per annum.
Will hydrogen powered cars change the dynamics? Who knows? What is a clear trend, the automotive sector, like other market sectors are moving rapidly towards renewables, a trend that is unlikely to change. I disagree with those who claim as this thread title says that renewables are not viable.
