Storing power generated by solar photovoltaics is one of the challenges facing our transition to alternative energy. Fuel cells, batteries, molten salt are all viable alternatives being considered for this purpose. Caltech researchers are exploring the use of nano-rods to catalyze the fuel cell chemistry - splitting water. ...
... "But there’s a bigger problem. Even if we had all the cheap photovoltaics we could ever need, we can’t store electricity in large quantities - you either use it or lose it. " ...Via Cal Tech: Quest for Catalysts, By Harry Gray
