Superconducting Magnetic Energy Storage (SMES) Power Interfaces
SBIR Opportunity Analysis
The Department of the Navy is seeking SBIR proposals for Superconducting Magnetic Energy Storage systems that can support intermittent pulsed power loads on future all-electric naval ships and provide a steadier load to shipboard generation. The work centers on developing an SMES architecture, controls, and related conversion schemes that can rapidly absorb and deliver energy for pulsed power duty cycles, with modeling, small-scale proof-of-concept testing in Phase I and a relevant-scale prototype in Phase II. Key technical targets include storing 4-10 MJ at 2-4 MW, charging and discharging above 1 MW, responding in sub-seconds, operating at greater than 80% duty cycle, and withstanding voltages above 1000 V, with Phase II testing also expected to show operation in elevated temperatures up to 122°F. The solicitation is open under number 26.BZ and topic DON26BZ01-NV016, with proposals due June 3, 2026 at 4:00 PM ET.
