About the company
Barrow Green LLC, a small-business for-profit limited liability company based in Bethesda, Maryland, delivers advanced cooling-systems research and clean-technology development to federal agencies as a prime contractor under SBIR Phase I and Phase II awards. The company competes exclusively under total small-business set-asides and has no presence on government-wide vehicles or indefinite-delivery vehicles.
Barrow Green's customer base is concentrated across two agencies. The Department of the Army accounts for two awards totaling $2.1 million in combined potential value, and the National Aeronautics and Space Administration Shared Services Center accounts for two awards worth $225 thousand combined potential value; these represent 100% of tracked awards. Army work includes a $1.9 million Phase II SBIR definitive contract awarded May 31, 2024, for monthly status reporting and contract-migration support from the PD2 system to the ACWS platform, with ultimate completion December 1, 2025, and a $249 thousand Phase I SBIR contract awarded September 28, 2022, for clean-technology research. NASA's Shared Services Center awarded a $224,945 Phase I SBIR definitive contract on September 30, 2026, for ultralight non-venting spacesuit thermal control, with performance through March 30, 2027. All work is performed in Westlake, Maryland, and carries firm fixed-price pricing.
The company's recent activity shows an intermittent award rhythm — one award in 2022, two in 2024, and one in 2026 — rather than sustained growth. One award (the NASA contract at $225 thousand) reaches ultimate completion within the next twenty-four months and faces recompete risk in that window. In its subcontractor role, Barrow Green performs as a sub-recipient on a University of Illinois federal grant for continuous bending-mode elastocaloric composite refrigeration systems, reflecting the company's deeper technical focus on elastocaloric and advanced-cooling-system research. SBIR work to date centers on applied research in advanced cooling, thermal management, and clean-technology innovation for defense and space applications, with demonstrated prior collaboration with the University of Illinois on elastocaloric composite systems.
