As I read over his article I was struck by the following thought, he mentioned "electricity cannot be stored" as one of the reasons why the current power grid is so interconnected, with the risks so dramitically illustrated earlier this month. My thought and question is, "is this still the case? Or, with fuel cells and/or other technologies might electricity be stored?"
Probably there is no way of storing electricity without some loss other than perhaps superconducting coils (where the electricity can go around and around in circles without loss), but are there means of harnessing energy currently as electricity and converting it to stored energy of another form? One that could ideally be quickly and easily converted back to electricity when there was demand?
It would seem to me that there must be, but perhaps it is a question of scale - i.e. it would take a lot of very large "rechargable batteries" to store the output of a small power plant, let alone a large one.
