The Southwest Research Institute has announced a joint industrial project (JIP) to support the development of infrastructure and fueling technologies for hydrogen-powered heavy-duty vehicles.
Southwest Research Institute is home to several hydrogen-energy-related initiatives, including the H2-ICE consortium, which completed the construction of a hydrogen internal combustion engine-powered heavy-duty vehicle (pictured left), and an on-site liquid hydrogen storage tank capable of holding up to 17,000 gallons of liquid hydrogen. These capabilities will aid the H2HD Refuel JIP’s efforts. Image Credit: Southwest Research Institute
SwRI’s H2HD REFUEL (Hydrogen Heavy Duty Refueling Equipment and Facilities Utilization Evaluation Laboratory) JIP is designed to support the adoption of hydrogen fuel in heavy-duty vehicles. By advancing hydrogen refueling station (HRS) technologies, SwRI aims to assist the mobility industry in meeting its decarbonization and zero-emissions targets.
Over the next four years, SwRI researchers will conduct hands-on experiments, system modeling, and theoretical studies to improve existing HRS equipment and methods while exploring potential replacements.
There are less than sixty hydrogen refueling stations in the U.S., but only one or two currently exist that can meet the specific needs of heavy-duty hydrogen-powered vehicles. Many light-duty hydrogen stations face significant technical challenges, including supply chain issues, mechanical failures, and lack of infrastructure. Considering the multimillion-dollar investment per station, these issues reflect a significant technology gap that industry and government must bridge before building additional heavy-duty refueling stations.

The H2HD REFUEL JIP brings together hydrogen vehicle manufacturers, original equipment manufacturers (OEMs), and refueling station operators to develop reliable and compatible HRS solutions.
The initiative will address various technical challenges, including determining the optimal onboard hydrogen storage method—liquid, H70 gas, or cryo-compression—and evaluating the performance of refueling station flow components. It will also examine hydrogen losses in cryogenic systems due to boil-off and other inefficiencies.
Connecting industry stakeholders is vital to developing compatible and reliable hydrogen refueling technologies and associated infrastructure. H2HD REFUEL’s comprehensive approach will ensure that the industry can meet the growing demand for heavy-duty hydrogen vehicles efficiently and safely. This JIP is another example of how SwRI is leading the way when it comes to hydrogen energy research.

H2HD REFUEL members will have access to SwRI-led cutting-edge research and hydrogen storage system models. Members can also engage in interactive workshops and bi-annual meetings to network and share expertise, as well as get vital economic and performance insights into various hydrogen storage systems.
