Several Chinese companies active in the energy storage space have recently released their financial reports for H1 2025, with the majority posting strong growth. Their energy storage business segments have been a key driver of that growth.

Chinese solar PV inverter and energy storage provider Sungrow has announced two major developments: plans for a Hong Kong IPO and the release of its half-year 2025 interim report.

Global energy storage technology and energy software services provider Fluence and ACE Engineering have opened a new automated battery storage manufacturing facility in Vietnam’s Bac Giang Province.

Iron flow battery company ESS Tech Inc (ESS Inc) has warned of substantial doubts about its ability to survive another year.

Fluence expects to hit the lower end of its previously issued revenue guidance for the 2025 financial year due to delays in ramping up at US production sites.

CATL, the world’s biggest lithium-ion OEM, saw flat ESS revenues in the first half of the year, but the extent to which this can be blamed on the increased US-China tariffs, if at all, is far from clear.

US zinc battery and energy storage system maker Eos Energy Enterprises has reported year-on-year revenue growth of 243% from the first half of 2024.

Tesla energy storage division saw its highest quarterly gross profits as the company’s automotive business continued to see dampened demand.

LG Energy Solution (LG ES) will nearly double the production capacity of battery cells for energy storage systems (ESS) at its Michigan, US, factory by the end of 2026.

Flow battery energy storage manufacturer ESS Inc. could achieve profitability “in the next few years,” if its new product is a success, the company’s CFO has said.
