vanadium redox flow batteries

SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

Canada-based Elcora said the transaction will enhance its mining operations and energy storage business.

Australian miner IGO is building upon its renewable energy options at its Nova nickel operation after signing an agreement with Perth-based energy storage company VSUN Energy to test a hybrid standalone power system backed by a vanadium redox flow battery.

Singapore-based VFlowTech has secured funds to scale up manufacturing of its vanadium redox flow batteries. The company currently offers three modular products that can be scaled to multi-megawatt-hour systems.

Australian Vanadium Ltd. has appointed a Western Australian engineering company to begin the first stage of what it says will be the country’s first vanadium electrolyte manufacturing plant.

The storage project is linked to a 1 GW wind and solar project portfolio, 500 MW of solar distributed generation, and the construction of a gigafactory for vanadium redox flow batteries in China.

Conceived by Swiss researchers, the battery shows good stability over 50 cycles, with an average energy efficiency of 68% and a water-splitting voltage efficiency of 64.1%. According to its creators, the device produces pure hydrogen that only needs to be dried and compressed for optimal storage.

Western Australian company Australian Vanadium Limited has been awarded $3.69 million in federal government funding to fast-track manufacturing of large-scale vanadium redox flow battery systems that can be used to support rooftop solar PV or in off-grid settings such as mining, agriculture and remote communities.

The battery will be provided by Canadian vanadium mining company Largo Resources. It will come online in the third quarter of next year.
