In search of the battery holy grail

There is a multitude of options for storing energy that may help overcome the variability of wind and solar. But none is a clear winner by itself and they all require improvement.

As discussed in the Climate Spectator article ‘Wind and solar are not enough’, it is incredibly important we achieve greater progress in technologies that would help complement the short-term variability of wind and solar. Both solar PV and wind technologies can play a valuable role in displacing generation from fossil fuels (the overall quantum of electricity produced by fossil fuels) but they aren’t so good at displacing the capacity from fossil fuels (the potential to produce electricity on demand at any time).
