Italian entrepreneurs who migrated to Stony Brook University's energy incubator to form an innovative-battery startup are planning to take on the Powerwall of Elon Musk's Tesla Inc.
Their Stony Brook company, StorEn Technologies, is adapting vanadium-flow batteries _ typically the size of shipping containers and found in utility or industrial settings _ for light commercial or household use.
StorEn's battery units, about the size of a large, cylindrical vending machine, could be used as a backup in case of a power outage.
