Southwest Research Institute (SwRI) has initiated an innovative joint industry project (JIP) designed to accelerate the development of hydrogen refueling technologies and infrastructure for heavy-duty vehicles.
This initiative, named H2HD REFUEL (Hydrogen Heavy Duty Refueling Equipment and Facilities Utilization Evaluation Laboratory), focuses on promoting hydrogen fuel use in heavy-duty transportation. The project aligns with efforts to achieve decarbonization and zero-emissions by enhancing hydrogen refueling station (HRS) technologies. Over the span of four years, SwRI researchers will conduct experiments, system modeling, and theoretical studies to improve current HRS equipment and procedures, while also exploring potential new solutions.
Dr. Thomas E. Briggs, Jr., from SwRI’s Powertrain Engineering Division, noted the scarcity of suitable hydrogen refueling stations in the U.S., with only a few meeting the needs of heavy-duty hydrogen vehicles. He emphasized the significant technology gap that exists, citing challenges light-duty hydrogen stations face, such as supply chain issues, mechanical failures, and infrastructure limitations. The H2HD REFUEL project aims to bridge these gaps by fostering collaboration among hydrogen vehicle manufacturers, original equipment manufacturers (OEMs), and refueling station operators. This will facilitate the development of reliable and compatible HRS technologies.
The program will delve into various HRS-related issues, seeking solutions to current technical challenges. Among these are identifying optimal onboard hydrogen storage methods—whether liquid, H70 gas, or cryo-compression—and evaluating the performance of different refueling station components. The JIP will also study hydrogen loss in cryogenic systems due to boil-off and inefficiency. Angel Wileman, the project manager from SwRI’s Mechanical Engineering Division, highlighted the importance of industry collaboration for developing robust hydrogen refueling technologies and infrastructure.
H2HD REFUEL aims to ensure efficient and safe support for the increasing demand for heavy-duty hydrogen vehicles. The JIP exemplifies SwRI’s leadership in hydrogen energy research. Participants will have access to SwRI-led advanced research and hydrogen storage models, alongside opportunities for networking and knowledge exchange through workshops and bi-annual meetings. Members will also gain insights into the economic and performance aspects of various hydrogen storage systems.
