Lithium battery prices could fall from $550 per kWh in 2014 to $200 per kWh by 2020. That whopping 65% is one of the results of an energy storage study published by the Australian Renewable Energy Agency.
This would be a game changer in the RV environment, by making such a battery bank overall much more affordable, with big technological improvements over lead-acid batteries. Such a quick adoption would equal the current implementation of solar energy, which has been the second-largest source of new electricity generating capacity in the US.
Battery prices will be under big pressure starting 2016 when Elon Musk’s monster factories will go on-line and start producing 500,000 Lithium batteries a year in Nevada. May be just in time for my van conversion!
