Form Energy finally lifted the veil of secrecy over its technology that purports to store clean electricity for days on end.
The startup revealed Thursday that it is building iron-air batteries, a technology that has been studied for decades but never commercialized for grid storage. The announcement coincided with a profile in the
Wall Street Journal and a $200 million Series D raise led by global steel and mining giant ArcelorMittal.
“We felt that we had made enough progress that it was relevant to talk about,” Form CEO Mateo Jaramillo told Canary Media Thursday.
The company had filed for the patents it needed to secure its intellectual property, he added. And when news broke that a steel company, which sources massive amounts of iron, was taking a stake in Form, some people probably could have connected the dots.
