A few large-scale ideas here: 
and for the truly small-scale: 

Technology's running off in more directions than there are dimensions 
(slight hyperbole there). To pretend that anything is proven to be 
"impossible" shows ignorance and arrogance (or perhaps a vested interest).

On that, there's the Weißbach paper 
(to which I don't have access) referenced in a post on Barry Brook's 
pro-nuclear blog
<http://bravenewclimate.com/2014/08/22/catch-22-of-energy-storage/> and
To which my only comment is that the figures are comically rubbery: 

Most of the "debate" about renewables and storage seems to centre around 
the nuclear power lobby.

To get this a bit more on topic for Link, I reckon much of the solution 
lies in demand management, "smart grids" and other efficiencies.
