Safe Lithium-Ion Battery Development

The Department of Energy, through the Naval Nuclear Laboratory (NNL) operated by Fluor Marine Propulsion LLC, is seeking proposals for the development of a lithium-ion battery prototype designed as a backup energy storage system. The battery must provide 2.4 MW*hrs of usable energy and demonstrate a robust safety posture capable of maintaining operations during and after a "credible casualty" scenario. Key contract objectives include developing a battery system that meets specific energy and power demands while fitting within specified dimensional constraints and maintaining an acceptably low risk profile. The evaluation will focus on the battery's technical capabilities, safety features, and overall system reliability. Vendors must submit their detailed proposals by April 7, 2025, with an information session scheduled for February 27, 2025, between 1100-1200 EST, and funding decisions anticipated by October 2025.

The solicitation is not set aside for any specific business category and is open to qualified vendors in the research and development sector. The prototype development is for a single unit, with no guaranteed additional purchases, targeting a battery system that can operate within a 210-355 VDC voltage range and provide over 1000 charge cycles throughout its service life. The place of performance is within the United States, with the battery system required to meet NAVSEA safety standards and fit within a 21' long x 10' wide x 6.5' tall space. The project will be executed in three phases: conceptual design, detailed design, and manufacture/test, with deliverables including battery modules, battery management system, interface equipment, design reports, and test procedures. While no specific award value is mentioned, the solicitation represents a prototype development contract focused on advanced energy storage technology for critical infrastructure applications.
