About the NHI
The NHI program evolved from the High Temperature Heat Exchanger (HTHX) program. The HTHX was a research team led by the University of Nevada, Las Vegas (UNLV) Research Foundation to develope advanced high temperature heat exchangers (HTHX) for hydrogen production and electrical energy conversion from advanced nuclear reactor concepts. Collaborators included researchers from UNLV, General Atomics (GA), Sandia National Laboratories (SNL), the University of California, Berkeley (UCB), the Massachusetts Institute of Technology (MIT), and Oak Ridge National Laboratory (ORNL).
HTHX was intended to establish a public-private partnership to develop and evaluate innovative high temperature heat exchangers for hydrogen production. The partnership focused initially on engineering evaluation of heat exchangers for two hydrogen production technologies (thermally assisted electrolysis and the sulfur-iodine thermochemical cycle) that couple with a nuclear reactor power source to split the water molecule into its constituent parts. However, advanced high temperature heat exchangers are important to nearly all hydrogen production concepts and the range of processes that the U.S. Department of Energy (DOE) considered were re-evaluated.
