The Energy Storage Report 2026 is packed with insights, analysis and fresh reporting on the headline topics in BESS today.

Global long-duration energy storage (LDES) deployment figures soared in 2025, but newer technologies risk being outcompeted by the incumbent, lithium-ion (Li-ion).

ESN Premium takes advantage of an opportunity to compare Europe and US energy storage markets with Wood Mackenzie energy storage analysts.

The first monthly global grid-scale BESS deployment figures for 2026 are in from Rho Motion, showing a year-on-year fall and China continuing to account for the majority of activity.

European Union countries deployed record-breaking battery storage capacity for the 12th consecutive year in 2025.

The global energy storage market is poised for continued expansion in 2026, even as supply chain constraints, regulatory evolution, and emerging applications reshape the landscape, according to Wood Mackenzie. 

The UK market saw strong interest and activity in 2025 but now appears to be shifting from a development market to one focused on execution, writes Solar Media analyst Charlotte Gisbourne.

The UK grid-scale battery storage market grew 45% in 2025, with 4GWh coming online during the year, bringing total operational capacity to 12.9GWh.

Ford Motor Company’s entry into the “fiercely competitive” energy storage market is a “big strategic pivot,” but one that makes sense, ESN Premium has heard.

Cell manufacturing overcapacity and intense competition contributed to an 8% decline in the average cost of lithium-ion battery packs, according to BloombergNEF.
