HYSKY Monthly’s latest episode featured an insightful presentation from Southwest Research Institute (SwRI), a powerhouse in applied research and technology development. The discussion, led by Dennis Long and Dr. Richard Fu, provided a deep dive into SwRI’s hydrogen research initiatives, with a focus on hydrogen fuel cells, infrastructure, and testing methodologies.
Introduction to SwRI and Its Hydrogen Research
SwRI, a nonprofit research organization founded in 1947, has a broad technological reach spanning automotive, aerospace, energy, and defense. With over 3,200 employees and nearly a billion dollars in annual revenue, SwRI is a major player in advancing hydrogen technologies. Their research focuses on hydrogen storage, fuel cell optimization, combustion, and safety testing—critical areas for the future of hydrogen aviation.
Advancements in Hydrogen Aviation Fuel Cells
Dr. Fu outlined SwRI’s fuel cell research timeline, highlighting their extensive work in testing and validation. Key projects include:
Toyota Mirai Fuel Cell Benchmarking – SwRI analyzed the vehicle’s hydrogen fuel cell system, identifying areas for efficiency improvement through better control strategies.
Thermal and Environmental Testing – Hydrogen fuel cells are subjected to extreme temperatures, humidity cycles, and altitude simulations to evaluate performance in harsh conditions.
Durability and Lifecycle Analysis – Fuel cell stacks undergo extensive testing, ensuring reliability for heavy-duty applications, including aviation.
High-Temperature Proton Exchange Membrane (HT-PEM) Development – In collaboration with the University of Connecticut, SwRI is pioneering next-generation membranes that offer higher efficiency and better thermal management than traditional Nafion-based PEMs.
Hydrogen Infrastructure and Refueling Challenges
One of the biggest obstacles in hydrogen adoption is refueling infrastructure. SwRI is tackling this through its H2HD Refuel Consortium, which brings together industry leaders to optimize refueling station designs. Their research aims to:
Improve hydrogen compressor and cryogenic pump efficiency.
Establish standardized refueling protocols for heavy-duty applications.
Address boil-off management to reduce hydrogen loss in storage and transportation.
Enhance refueling station reliability, leveraging lessons learned from light-duty vehicle infrastructure challenges.
Hydrogen Safety Testing and Standards
Safety remains a top priority in hydrogen aviation and mobility. SwRI’s Fire Technology Department conducts rigorous safety evaluations, including:
Bonfire and Gunfire Testing – Assessing the structural integrity of hydrogen fuel tanks under extreme conditions.
Drop and Impact Testing – Simulating real-world accidents to understand failure points.
Explosion and Dispersion Analysis – Modeling hydrogen leaks and combustion scenarios to develop safer handling protocols.
Aviation’s Role in Hydrogen Innovation
A key discussion point was how SwRI’s research aligns with aviation needs. While much of their work has been focused on automotive and heavy-duty vehicle applications, the crossover into aviation is clear. Aviation presents unique challenges due to strict regulatory requirements and the need for lightweight, high-efficiency hydrogen storage and power systems. SwRI welcomes collaboration with aviation stakeholders to further refine hydrogen technologies for flight applications.
Bridging the Gap Between Hydrogen and Aviation
HYSKY Society’s mission is to bridge the gap between hydrogen and aviation, making SwRI’s research invaluable to the community. As hydrogen-powered aircraft development accelerates, partnerships with research institutions like SwRI will be crucial in overcoming infrastructure, efficiency, and safety hurdles.
Next Steps and Industry Collaboration
SwRI encourages industry professionals to engage in their consortiums and leverage their extensive testing facilities. HYSKY Society, in turn, will continue to connect innovators across the hydrogen aviation ecosystem through upcoming events like the Hydrogen Hub Summit on March 19, 2025.
HYSKY’s Mission
HYSKY Society is a 501(c)(3) nonprofit committed to decarbonizing aviation and aerospace with hydrogen. We welcome innovators from eVTOLs/advanced air mobility, fixed-wing aircraft, and spacecraft. Our mission is simple: if it defies gravity and uses hydrogen as fuel, it’s part of our vision for sustainable flight.
