Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours.

SolarDuck, Green Arrow Capital, and New Developments have agreed to develop an offshore hybrid project featuring 120 MWp of PV and 420 MW of wind in Calabria, Italy.

Swiss solar panel maker Meyer Burger will seek shareholder approval for a rights issue of as much as CHF 250 million ($284 million) to finance the completion of its US manufacturing facilities in Colorado and Arizona.

The Serbian Ministry of Mining and Energy has signed a memorandum of understanding (MoU) with Chinese companies Shanghai Fengling Renewables and Serbia Zijin Copper. It envisages the construction of 1.5 GW wind and 500 MW of solar projects alongside a green hydrogen production facility with 30,000 tons of annual output.

French sodium-ion battery maker Tiamat has raised €30 million ($32.6 million) in equity and debt financing. It will use the funds to launch the construction of a 5 GWh production plant in the Hauts-de-France region.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.

US-based Acculon Energy has announced series production of its sodium-ion battery modules and packs for mobility and stationary energy storage applications. Scaled production of 2 GWh is scheduled to start in mid-2024.

KPIT, an India-based automotive software and engineering solutions supplier, has unveiled its proprietary sodium-ion battery technology, and is now on the lookout for manufacturing partners. Ravi Pandit, chairman of KPIT, tells pv magazine, that that the company has developed multiple variants with energy density ranging from 100 Wh/kg to 170 Wh/kg, and potentially reaching 220 Wh/kg.

Enerpoly, a Swedish startup that produces zinc-ion battery storage systems with durations of two to 10 hours, plans to scale production up to 100 MWh per year by 2026.

Fourth Power, backed by Bill Gates’ venture firm, has developed high-density thermal energy storage based on thermophotovoltaic cells. The tech, which is reportedly 10 times cheaper than lithium-ion batteries, is based on the U.S. company’s patented liquid metal heat transfer system.
