“All very well, but is there currently a viable storage product available in the near future? If so, who is co-developing the product and what's it called?”

Fair point but consider a decade or more ago, when there seemed to be minimal research and development on batteries.  Today, on a ‘needs must’ basis, an enormous and varied effort is underway to produce reliable batteries of all sizes.  My guess is that they will be readily available within a few years.
