U.S. Sen. Shelley Moore Capito says she is amazed by the changes seen in north Weirton in the last few years Capito, R-W.Va., was in the city Monday to visit Form Factory 1, receiving a tour and update on development of the facility constructed to manufacture iron-air batteries on property once used in the making of steel. It was part of a series of stops in the Northern Panhandle. “What a great investment,” she said of the facility, which has been under construction for the last year. “It’s such an uplifting feeling.” As part of the tour, Capito was able to learn about the engineering, testing and assembly of the batteries developed by Form Energy, which are designed to provide 100 hours of power storage, as well as its quality control procedures.
