The Southwest Research Institute (SwRI) has launched the H2HD Refuel joint industry project (JIP) to enhance fueling technologies and infrastructure for hydrogen-powered heavy-duty vehicles. Over the next four years, SwRI researchers will conduct hands-on experiments and theoretical studies to strengthen existing hydrogen refueling station (HRS) equipment and explore alternative onboard hydrogen storage methods. Dr. Thomas E. Briggs, Jr., an institute engineer at SwRI, emphasized the need to bridge the technology gap in heavy-duty refueling stations due to technical challenges faced by existing light-duty stations. The H2HD Refuel project aims to connect hydrogen vehicle manufacturers, original equipment manufacturers, and refueling station operators to develop dependable and innovative HRS technologies. Areas of investigation include onboard hydrogen storage methods such as liquid, H70 gas, or cryo-compression, as well as the performance of refueling station flow components. Additionally, the project will focus on studying hydrogen losses from cryogenic systems to enhance system efficiency. Angel Wileman, the JIP project manager at SwRI, highlighted the importance of industry collaboration in developing compatible and reliable hydrogen refueling technologies. Members of the project will have access to SwRI-led research, hydrogen storage system models, and opportunities for networking and knowledge sharing through workshops and meetings. By fostering collaboration and addressing technical challenges, the H2HD Refuel project aims to support the efficient and safe growth of heavy-duty hydrogen vehicles, contributing to SwRI's leadership in hydrogen energy research.
