US Navy funds Eta Space to develop advanced cryogenic cooling systems

Eta Space awarded Phase I STTR contract in partnership with Florida State University

ROCKLEDGE, FL, UNITED STATES, July 10, 2025 /EINPresswire.com/ -- Eta Space has been awarded a Phase I STTR contract to research rapid cryogenic cooling of superconducting systems for defense applications. The six-month contract with Florida State University’s Center for Advanced Power Systems (CAPS) began July 7.

Eta Space will research and develop hardware and processes to rapidly cool large, High-Temperature Superconducting (HTS) magnets down to cryogenic temperatures within 24 hours, as opposed to several days. The development would help the U.S. Navy achieve its goal of reducing the cooling time for HTS magnet systems to operational temperatures, providing robust operational capabilities for minesweeping missions. Future potential applications of HTS technologies include motors, generators, cables and more.

“Advancing research in high-temperature superconductors has the potential to open doors for future work with the Navy and benefit a wide range of applications,” said Daniel Hollibaugh, principal investigator for the contract. “This collaboration with FSU through the Center for Advanced Power Systems offers strong synergy between our expertise in cryogenics and their work with magnets and advanced power systems,” Hollibaugh said.

The Phase I contract will consist of thermal design and analysis with an optional period of prototype testing. Upon successful Phase I execution, the Eta Space and FSU team from the FAMU-FSU College of Engineering led by Professor Juan Ordóñez, along with Peter Cheetham, Ph.D. and Chul Kim, Ph.D., will demonstrate the capability at a relevant scale in a laboratory environment. The demonstration will be conducted at Eta Space’s in-house facility. This contract offers a paramount achievement for Eta Space as the company ventures into its upcoming division, Eta Defense.
