NSF IRES: Exploring Innovations in Hydrogen Technologies at the Hydrogen Ship Technology Center in Republic of Korea

This project provides U.S. students with a ten-week international research experience at the Hydrogen Ship Technology Center (HSTC) at Pusan National University in South Korea, one of the few global hubs with infrastructure and expertise for liquid hydrogen transportation. Students work alongside Korean researchers and are co-mentored by faculty from UConn and PNU, gaining technical skills and international collaboration experience. Research spans fuel cell performance, cryogenic storage, material degradation under hydrogen exposure, and recovery of cold energy from boil-off gas, combining full-scale experiments, material testing, and modeling to advance technologies for zero-emission vehicles in shipping, aviation, and heavy-duty logistics.

Dr. Ji Ho Jeon Receives NSF IRES Award for Collaborative Research with Pusan National University

Dr. Ji Ho Jeon has been awarded $435,527 in funding from the NSF International Research Experiences for Students (IRES) program to send eight U.S. students each year for three years to conduct collaborative research at the Hydrogen Ship Technology Center at Pusan National University in South Korea. The project, led by Dr. Jeon as Principal Investigator, focuses on key challenges related to LH₂-based transportation, including fuel cell performance, cryogenic hydrogen storage, and material degradation under extreme conditions. Students will actively participate in hands-on research involving experimentation, material testing, thermal-fluid modeling, and finite element simulations.
