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.
Maxeon claims 24.9% efficiency for IBC solar panel
Maxeon said it has achieved a 24.9% efficiency rating for a full-scale Maxeon 7 solar panel using its IBC technology. The US National Renewable Energy Laboratory (NREL) confirmed the result.
Weekend Read: Gray skies over Californian solar
There may be a global solar boom but a drastic revision of California’s net metering program has ruptured the industry overnight and is affecting everyone from installers to financiers to makers of power electronics.
The Hydrogen Stream: Germany mulls Namibian hydrogen investment
The German government has confirmed the suitability of Hyphen’s hydrogen project in Namibia for potential investment, while Topsoe has completed a 2,000-hour demonstration of 12 solid oxide electrolyzer cell (SOEC) stacks.
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 undersizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.
U.S. Boiler unveils hydronic heat pump for residential applications
The US-based manufacturer said its new heat pump system has 5-ton capacity and a coefficient of performance of up to 3.95. It uses difluoromethane (R32) as the refrigerant and relies on DC inverter enhanced vapor injection (EVI) technology.
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.
US energy storage sector booming, says Wood Mackenzie
Lower costs, better supply chains and steady demand are driving an energy storage boom in the United States, according to a new report from Wood Mackenzie.
