“why solar power has so many limitations. Solar is great when the sun is shining, but storing solar power require the deployment of a large array of heavy, expensive and toxic electrical storage devices known as “deep cycle batteries.” To put it in street terms, deep cycle battery technology sucks. The batteries suck, the chemicals suck, the weight sucks and the cost sucks. There is absolutely nothing to like about batteries unless you enjoy hulking around with heavy, useless objects.
So the “holy grail” of solar power has always been finding a way to store solar energy that’s portable, dense and relatively lightweight. Until now, that discovery has been elusive.
But now a team of scientists in Boulder, Colorado say they have come up with “a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel.””-The Watcher
