Iron-based redox flow battery for grid-scale storage
Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.
Inverter undersizing not universally effective to reduce soiling losses
An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter under sizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.

California cuts interconnection costs for distributed solar developers that agree to export limits
By agreeing to limit exports to the grid at peak generation hours, distributed energy resources like rooftop solar and energy storage can now avoid delays and costly infrastructure upgrades.
Sodium-ion batteries – a viable alternative to lithium?
