The Department of Defense, specifically the Navy, is seeking proposals for the development of a High-Density Energy Storage System (HESS) under the Direct to Phase II SBIR program. The objective is to create a HESS capable of interfacing with an existing medium voltage motor drive system, with specific requirements including energy storage capacities of at least 1.1 megajoules (MJ) and a system capacitance exceeding 1.5°F, among other technical specifications. This technology is critical for enhancing energy efficiency and performance in military applications, particularly in the context of advanced materials and renewable energy generation. Proposals are due by May 21, 2025, and interested parties can find more information at the provided source link: https://www.sbir.gov/topics/11950.
