China’s Huawei will supply batteries to British power producer Aggreko for what both companies describe as Brazil’s largest energy storage system to date, supporting renewable microgrids across the state of Amazonas.

TotalEnergies has agreed to sell a 50 percent stake in a portfolio of 11 battery storage projects to Allianz Global Investors, advancing nearly 800 MW of new capacity scheduled to enter operation by 2028.

Utility scale energy storage additions in the United States reached 58 gigawatt hours in 2025, a 30 percent year over year increase that pushed total installed capacity to 137 gigawatt hours, according to the latest data from Solar Energy Industries Association.

A single metric is increasingly shaping investment calculus for battery energy storage systems across European power markets: the Top-Bottom spread,…

During a recent visit to China alongside German Chancellor Friedrich Merz, BMW Group CEO Oliver Zipse signed a memorandum of understanding with CATL, formalizing a partnership aimed at lowering the embedded carbon footprint of BMW’s electric vehicles by reworking battery sourcing and production processes.

Australia’s energy storage buildout is increasingly defined by a geographic and technological split. In New South Wales, the state government has elevated two pumped hydro proposals totaling 1.8 gigawatts to priority planning status, even as battery energy storage systems continue to dominate deployment elsewhere in the country.

The U.S. energy storage sector installed 57.6 GWh of new capacity in 2025, marking the largest single-year deployment in history.

Europe’s installed battery capacity surpassed 17 gigawatts in 2025 after adding more than 7 gigawatts in just two years, yet deployment remains uneven across the continent.

Japan added roughly 3 GW of battery energy storage capacity across utility scale and distributed assets by the end of 2024, according to industry estimates, but participation has remained concentrated among power companies, developers, and trading houses.

Researchers at Case Western Reserve University have developed an electrolyte architecture that enables protons to conduct charge via a “hopping” mechanism, offering an alternative to volatile, flammable liquids that dominate conventional battery designs such as lithium‑ion.
