Summary

Mateo Jaramillo, CEO of Form Energy, presents the company’s mission to develop low-cost, multi-day energy storage using iron-air battery technology. He begins by describing his background at Tesla and the founding of Form Energy, emphasizing the importance of solving the problem of long-duration storage without preconceived solutions. The company has raised $1.2 billion in equity and $600 million in grants, and operates in Boston, California, and West Virginia. The core technology is an iron-air battery that reversibly rusts iron, a chemistry studied by Westinghouse 50 years ago. The system is designed for 100-hour duration, targeting $20 per kilowatt-hour, which would make it competitive with natural gas. Jaramillo discusses the manufacturing process, including the acquisition of air cathode technology from NantEnergy and nickel-iron battery knowledge from another company. He highlights the deployment at a site in Minnesota and the establishment of a factory in Weirton, West Virginia, on the site of a former steel mill. The lecture concludes with the vision of providing firm capacity resources that are available more than 90% of the time, essential for grid reliability in the face of increasing demand and renewable integration.
