Operational issues hit returns in one in five battery storage projects, report finds

A recent report from battery intelligence firm Accure reveals that while most battery energy storage systems (BESS) operate reliably, nearly 19% of projects experience reduced returns due to technical issues and unplanned downtime. From ESS News BESS are fast becoming central to the global energy transition, but the sector still faces significant operational and financial […]

Startup unveils zinc-polyiodide redox flow battery with energy density of 320 Wh/L

BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory. From ESS News US-based startup BESSt has launched a new redox flow battery technology that reportedly achieves 20 […]

NREL researchers address safety implications of next-generation battery technologies

Report says new evaluation methods, including AI, will help make future batteries safer. If lithium-ion batteries were once viewed as an expensive energy storage solution with tenuous supply chains, mass production has made them both affordable and readily available for a wide variety of applications. Consumer electronics, electric vehicles and, importantly, battery-based energy storage systems […]

New wave of funding powers U.S. battery tech and projects

XL Batteries has secured backing to commercialize flow battery systems which use an organic electrolyte, rather than vanadium, and two utility-scale developers have landed extensive credit lines. The announcement of $7.5 million of funding for a Massachusetts company to scale its organic flow battery technology capped a 24-hour period this week which saw almost $900 […]

Telemetry could impact ERCOT’s rollout of real-time co-optimization with batteries

Projects that fail to upgrade their data infrastructure risk underperformance, delays, and lost trust with the network operator. From ESS News ERCOT is set to roll out its real-time co-optimization with batteries program (RTC+B), which could open up new value streams for batteries. But the rollout hinges on something deceptively simple: telemetry. “The real risk […]
