Greg Archer, managing director of the LCVP, said falling battery costs would help electric cars compete in the next 15-20 years. "After 2020 the range of new technology will be more commercially available. It's obvious that there needs to be a reduction in the price of batteries and fuel cells to achieve market share and become competitive. It remains to be seen if [cost] reductions will be achieved, but these [the projections in the report] are not conservative estimates, they are the best estimates based on probability."
