5B uses modular, relocatable solar tech for 89.7 MW hybrid microgrid

Modular solar array manufacturer 5B has started building the solar component of an 89.7 MW hybrid microgrid that will help Bellevue Gold’s gold mine in Australia with up to 100% renewables.

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.

Hydrogen batteries vs. lithium-ion batteries

Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.
