NASA has awarded contracts to Air Products and Chemicals and Linde to supply up to approximately 15-MM pounds of liquid H₂ for use at facilities across the agency.

The indefinite delivery requirements contracts include multiple firm-fixed price delivery orders with maximum values of approximately $57.3 MM for Air Products and Chemicals and approximately $29.1 MM for Linde. Each contract begins Dec. 1 and consists of a two-yr base period followed by an option period that, if exercised, would extend the contract to Nov. 30, 2025.

Under these contracts, Air Products and Chemicals will supply up to about 13.1-MM pounds of liquid H₂ to NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Stennis Space Center in Bay St. Louis, Mississippi, while Linde will deliver up to approximately 1.89-MM pounds of the commodity to the agency’s Glenn Research Center in Cleveland and Armstrong Test Facility in Sandusky, Ohio, as well as NASA’s Kennedy Space Center (including Cape Canaveral Space Force Station) in Florida.

NASA uses liquid H₂, combined with liquid oxygen, as fuel in cryogenic rocket engines, and the commodity’s unique properties support the development of aeronautics.
