WASHINGTON, Dec 22 (Reuters) - Form Energy Inc, a startup hoping to make long-duration storage batteries from materials including iron to store power from renewable energy, will partner with West Virginia to build a manufacturing plant in the state, the company and politicians said on Thursday.
West Virginia Governor Jim Justice and Form Energy, backed by supporters including Bill Gates' Breakthrough Energy Ventures, said the plant will be built with a total investment of up to $760 million.
Form Energy aims to build batteries using iron, air and water.
Form says the batteries can store power for days, much longer than ones based on lithium-ion, and using less expensive materials.
"The path forward is innovation, not elimination, and with this announcement West Virginia and Form Energy are doing just that," Manchin said in a statement.
