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.
U.S. grid-scale storage leaps 63%, residential storage 132%
The utility-scale energy storage sector added 4.9 GW in Q2, representing 63% year-on-year growth, while residential storage increased by 608 MW, said a report from American Clean Power Association and Wood Mackenzie.
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.
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.
Deploy grid-forming batteries now to avoid costly infrastructure later, says ESIG
Large-scale batteries with grid-forming software can sustain grid reliability as renewables replace synchronous fossil generators, says an ESIG report. The report focuses on test procedures to validate grid-forming capabilities.
Flatiron Energy secures $540 million for largest battery project in Massachusetts
The company is expected to bring a 200 MW / 800 MWh battery to commercial operations by late 2026.
Making sense of CAISO’s bid cost recovery mechanism and what it means for batteries
As California batteries increasingly depend on bid cost recovery to smooth out market deviations, the make-whole mechanism is being reshaped to balance flexibility and fairness.
Sungrow unveils modular inverter, battery energy storage systems
The company introduced a 4.8 MW modular inverter, a utility-scale battery energy storage system and a commercial and industrial scale battery energy storage system at the RE+ trade show in Las Vegas, Nevada.
Minnesota ushers in first standalone energy storage project
After Spearmint Energy applied for two separate but similar 150 MW energy storage projects, one will break new ground while the other faces ongoing hurdles from local opposition.
Grid-scale energy storage could cut energy bills in Central U.S. by $7 billion
The Southwest Power Pool is expected to have the largest increase in peak demand among grid regions in the United States. Energy storage can help serve this demand cost effectively, said Aurora Energy Research.
