This post looks at fifteen kinds of utility or grid scale energy storage solutions that are either in wide use or have significant potential to supply the energy storage capacity that will help make the grid both more efficient and more robust. These range from pumped hydro, which is by far the most prevalent form of energy storage at this scale to compressed air, thermal storage, advanced batteries, fuel cells and purely electric storage systems.
This post answers the recently much hyped focus on wind’s variability problem, quantifying it in clear cost terms that put it in perspective. The post helps clarify the differences between energy, capacity and the ancillary services surrounding ensuring capacity and goes on to answer some of the other related problems that have been alleged for wind energy as its penetration level increases.
