Southwest Research Institute (SwRI) has initiated the H2HD REFUEL Joint Industry Project (JIP) in San Antonio to drive advancements in hydrogen fueling for heavy-duty vehicles. The project's primary goal is to strengthen the acceptance and utilization of hydrogen fuel by heavy-duty vehicles to facilitate the mobility industry's decarbonization and zero-emissions objectives. Over the next four years, SwRI researchers will conduct a comprehensive analysis involving hands-on experiments, system modeling, and theoretical studies to improve existing hydrogen refueling station (HRS) technologies and explore potential alternatives. The JIP will bring together hydrogen vehicle manufacturers, original equipment manufacturers (OEMs), and refueling station operators to develop innovative and compatible HRS technologies. Key areas of focus include investigating the best onboard hydrogen storage method, optimizing refueling station flow components, and mitigating hydrogen losses from cryogenic systems. By fostering collaboration among industry stakeholders, the project aims to bridge the technology gap hindering the expansion of heavy-duty hydrogen refueling stations. Participants in the H2HD REFUEL JIP will have access to SwRI-led research, interactive workshops, and valuable insights into different hydrogen storage systems. Through this initiative, SwRI continues to lead in hydrogen energy research, supporting the growth of hydrogen-powered mobility in the United States.
