Why should people take ESS Inc and its pivot to sodium-ion BESS seriously, having failed to deliver on its iron flow battery promises since going public in 2021? We catch up with new CEO Drew Buckley about how he hopes to turn the ship around.

Energy storage deployments in China saw significant year-over-year growth in 2025 as the market size effectively doubled.

LG Energy Solution (LG ES) posted a profitable second quarter this year, with investments in battery storage in the US and EV cell production in Europe paying off.

In this deep-dive, we go through and analyse all of the technical features and claims of CATL’s new sodium-ion grid-scale BESS product, including its ‘millisecond-level self-healing’.

CATL’s energy storage division represented 19.23% of the Chinese battery manufacturer’s total revenue in the first half of 2026.

System integrator Alfen and battery company CATL have struck a 5GWh partnership for sodium-ion BESS deployments in Europe.

Some 9.1GW/33.5GWh of large-scale BESS came online globally last month, with Saudi Arabia accounting for over one-third of the figure.

We caught up with the CCO of Netherlands-headquartered startup Moonwatt at last month’s Smarter E Europe trade show in Munich for a video interview.

System integrator HyperStrong will deploy sodium-ion BESS first in its home market of China, before bringing a product to the international markets, its president of technology said.

Sodium-ion BESS startup Moonwatt expects the battery chemistry to reach price cost parity with lithium iron phosphate (LFP) in the next two or three years, according to its CCO, Valentin Rota.
