Global battery storage capacity is projected to expand sixfold between 2025 and 2030 at a 42% CAGR, driven by utility procurement, grid constraints, and power demand from AI data centres. The U.S. and China account for 74.6% of installed capacity, with project designs standardising around four-hour duration systems and co-located solar-plus-storage hybrids.

This Wire brief sits within Fusion42's coverage of Energy Storage and Clean Energy. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

◆ The Wire takeaway

Four-hour battery systems are now the grid standard, not a niche product—and data centres are buying them not for backup but to dodge interconnection caps and peak charges. If you make inverters, balance-of-system components, or grid-tie software, the addressable market just expanded six times over, with a clear duration spec that kills older two-hour architectures.
