Battery and energy storage targets falling well short of COP29 pledge

Global targets for battery and energy storage by 2030 have nearly tripled since COP29 but remain far below the pledge made, according to new data.

Ember said that the commitment at the last climate summit had called for 1,500 GW of storage by 2030, but the increase in global storage targets since is due almost entirely to new targets set by the EU and China.

Dr Kayte Altieri, analyst at Ember said most other major markets still haven’t set a 2030 storage target at all.

“And that’s a missed opportunity, because storage targets give investors the certainty to build,” she said.

Storage additions hit a record 118 GW in 2025, including 108 GW of battery storage. If that pace were sustained through 2030 with no acceleration, energy storage would reach 1,020 GW, more than the sum of current national targets. Additions have been growing at almost 80% a year since 2020, which is much faster than the modest growth needed to hit the full 1,500 GW storage pledge.
