Just last week, a report by Swiss bank UBS showed how the linked development of energy storage, solar power and electric vehicles is changing the economics of power generation. UBS predicts that by 2020, a return on investment for an unsubsidized purchase of an electric vehicle, coupled with a rooftop solar installation and battery storage, will drop to just six years in much of Europe. Smart distribution networks would precisely manage the usage and allocation of electricity, allowing for an electric car to be charged at night, for the sun to power a house during daylight hours and for improved batteries to store power for other residential uses. While such news might not be met with cheers in the offices of national grid operators, it shows just how the quest for "The Holy Grail of Energy Storage" is doomed to fail.
