Canada Battery Maker Says Flow Storage Costs to Tumble by Half. CellCube Energy Storage Systems Inc., a Canada-listed maker of batteries that can last for as long as two decades, said the cost of its technology may halve within four years, potentially boosting its uptake over lithium-ion units. Costs of its vanadium redox flow battery units, which can discharge power for four hours, will decline to $150 per kilowatt hour from $300, President Stefan Schauss said in a phone interview from Toronto this month. Batteries with eight hours of duration will slump to $100 from $200, he said.
