High-temp sodium-zinc batteries reveal causes of rapid capacity loss
Helmholtz-Zentrum Dresden-Rossendorf (HZDR) researchers have used operando X-ray imaging to reveal why sodium-zinc molten-salt batteries, operating at around 600 C and promising for stationary energy storage due to low-cost, abundant materials, experience persistent capacity loss.
Hoymiles releases all-in-one residential inverter and modular battery
The Chinese company said its modular system supports up to 64 kWh of storage, multiple PV inputs, and 0 ms backup switching for uninterrupted operation.
Made in Europe: Sungrow builds first European factory in Poland
Sungrow says it plans to invest €230 million ($274 million) in its first European factory in Wałbrzych, Poland, to produce inverters and battery energy storage systems (BESS).
Global BESS capacity tops 250 GW, overtaking pumped hydro for first time
Rystad Energy says it expects global battery energy storage system (BESS) additions to exceed 130 GW/350 GWh in 2026, led by China, the United States, the United Kingdom, Australia, and Germany.
EU installs 27.1 GWh of battery storage in 2025 as utility scale leads
The European Union added 27.1 GWh of battery energy storage capacity in 2025, with utility-scale systems accounting for the majority of new installations as residential storage declined amid lower electricity prices and reduced support schemes, according to a new report from SolarPower Europe.
How to combine C&I solar with compressed air energy storage
Researchers have studied the potential of combining photovoltaic systems with compressed air energy storage (CAES) to power a commercial building in South Africa. They found that a co-optimized system could lower total capital costs by 15–20% compared to traditional sequential sizing approaches.
EGbatt releases 15 kWh storage solution for residential use
The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of over 9,500 cycles at a high 95% depth of discharge.
Battery storage in Spain could become unviable beyond 32 GWh
Scientists from the University of Seville have developed real-time optimization models showing that electricity storage in Spain may be approaching its economic limit, with cumulative capacities above 32 GWh depressing prices and undermining project profitability.
Germany adds 6.57 GWh of battery storage in 2025, total hits 24 GWh
Germany added an estimated 6.57 GWh of stationary battery storage capacity in 2025, an increase of about 8% year on year, lifting total installed capacity to roughly 24 GWh. Growth was driven by industrial and large-scale systems, even as home storage installations declined alongside weaker rooftop solar demand.
Australia makes gains in electric vehicle uptake
Australia recorded a sharp rise in electric vehicle sales in 2025, with new-car sales data showing nearly 157,000 EVs were purchased nationwide, up 38% from the previous year.
