Canada’s Electrochem Technologies & Materials has started commercial production of all-vanadium equimolar electrolyte solutions directly from vanadium pentoxide purchased on the market by using a novel process.
Production of the electrolyte for vanadium redox flow batteries “is now performed on demand” at Electrochem’s facilities in Quebec, using the company’s proprietary VRFBEX unit.
The process uses VEPT (VanadiumCorp-Electrochem processing technology)— which has been jointly developed with Vancouver-based mining and technology firm VanadiumCorp Resource.
Singaporean conglomerate the Keppel Corporation is buying into the lithium-ion batteries business with a US$50 million minority stake in Shanghai-based energy group Envision.
Keppel, whose businesses include infrastructure, offshore and marine and asset management, said its investment will “deepen our insights into the fast-growing electric vehicle market”.
Each microgrid will comprise 5-7kW of rooftop solar generation and 7-10kWh of lithium-ion battery storage.
