The National Aeronautics and Space Administration's (NASA) Glenn Research Center in Cleveland has launched an initiative to advance hydrogen technology for aeronautic applications. Through the Transformative Aeronautics Concepts Program (TACP), NASA is seeking industry input on the development of a dedicated cryogenic hydrogen testing facility. This facility aims to address system-level challenges in sustainable aviation by fostering innovative solutions. The RFI solicits responses from industry, academia, and government agencies to understand the requirements for a potential test facility. NASA is particularly interested in feedback on testing procedures, material limitations, infrastructure needs, and workforce training. The agency aims to establish standards for safe operations and cost-effective testing to support the resurgence of hydrogen as an energy carrier. Interested parties are required to submit their responses electronically in PDF format by 28 February 2025. The collaboration seeks to bridge gaps in research and technology development by creating a facility that can support ground and flight operations.
