New York to Install Battery Storage for Bus and Subway System Operator

American Vanadium Corp., owner of the only known U.S. deposit of vanadium, agreed to install an energy storage system designed to cut power costs for the firm that operates New York’s buses and subways. The $1.2 million project will showcase three vanadium-flow batteries which are capable of storing 130 kilowatt-hours each. Unlike standard lead-acid batteries or lithium-ion batteries, vanadium-flow batteries can be charged and discharged indefinitely and can last as long as 20 years.
