DOE Flow Battery Systems Manufacturing

Please see the full solicitation for complete information about the funding opportunity. Below is a summary assembled by the Research & Innovation Office (RIO). This program requires cost-share as noted in the Award Information section below; applicants should follow the RIO process described here.

Program Summary

DOE’s Office of Energy Efficiency and Renewable Energy (EERE) Advanced Manufacturing Office (AMO) aims to improve domestic flow battery systems’ manufacturing and validate as well as deepen the understanding of potential opportunities for increasing manufacturability for the energy storage community in general. Specifically, this FOA will advance the manufacturability of mid-sized flow battery systems to strengthen the domestic supply chain for flow battery technologies, focusing on specific technical barriers in specific components combined with an aim towards system integration. Desired projects will be expected to address gaps and challenges in energy storage manufacturing to:

  • Enable cost-effective and scale-up of flow battery manufacturing;
  • Test and validate manufacturing processes by producing a prototype flow battery system with industrially scalable processes; and
  • Strengthen the domestic flow battery manufacturing ecosystem that connects the battery manufacturing stakeholders, ranging from materials and equipment suppliers to component/system manufacturers.
