New stack design for cheaper redox flow batteries

German scientists have proposed a new design for stacks used in redox flow batteries. Through a powder-to-roll process, a device that weighs 80% less than a conventional stack was fabricated.

LG Energy recalling battery systems in Australia due to fire risks

The Australian Competition and Consumer Commission has confirmed a recall notice for some of LG Energy Solution’s battery energy storage systems due to potential fire-related risks.

Russian design for vanadium redox flow batteries

Researchers claim to have developed a cheaper, faster method of assembling the field flow plate layers of the membrane electrode assembly used in vanadium redox flow batteries, which they claim outperforms traditional components.

Turkey introduces new provisions for energy storage

Rules published in the official journal provide certainty on how storage systems will have to be connected to the grid and who will take care of the process on behalf of governmental institutions. The regulations are expected to benefit rooftop PV and up-to-1 MW ‘unlicensed’ projects

Batteries under solar modules just like microinverters and optimizers

Texan start-up Yotta Energy has a potential solution for residential solar-plus-storage. Will the micro-storage company become the next SolarEdge or Enphase or suffer the fate of JLM Energy? And whatever happened to SolPad?
