Global stationary battery deployment climbed to 286 GWh in 2023, yet the mix is far from uniform, with electrochemical systems taking a growing share while pumped storage still dominates electricity storage by energy capacity. At the same time, the US market surged from $3.0 billion in 2019 to a projected $10.1 billion in 2023, and interconnection pipelines are now shaping what storage durations get built. This post pulls those threads together so you can see how policy, technology limits, and grid needs translate into very different outcomes across regions.
