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.

India’s NTPC has allocated 1,584 MW of renewables-plus-storage projects at $0.056/kWh. The winning developers will set up renewable energy projects backed by energy storage systems to provide firm, dispatchable renewable energy, developed on a build-own-operate basis.

The need for long-duration energy storage in a net-zero world is undeniable but with conventional battery prices tumbling, can anything dislodge the mainstream grip of lithium ion? S&P Global’s Susan Taylor provides an update on non-lithium storage technologies.

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand. Marija Maisch reports.

UK-based Konexa has finalized a deal that will see Climate Fund Managers and Microsoft’s Climate Innovation Fund invest $18 million to establish Nigeria’s inaugural private renewable trading platform and provide renewable energy to Nigeria Breweries.

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.

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.

Gas and electricity company APA Group has launched Australia’s largest remote-grid solar farm, announcing the official opening of the 88 MW Dugald River Solar Farm in outback Queensland.

A Mercedes-Benz factory in Germany is set to host an 11 MWh organic flow battery to store solar energy generated by its rooftop PV installation. Germany’s CMBlu has provided its Organic SolidFlow technology for the project.

Engie has deployed a 139 MW/638 MWh battery in northern Chile. The storage project is connected to the 181.2 MW Coya solar plant in the Antofagasta region.
