Exploiting Hydrogen-Induced Phase Transformations for High-Temperature Applications

Tae Wook Heo | 22-ERD-002

Executive Summary

We will establish an integrated modeling and experimental approach to investigate key thermodynamic and kinetic mechanisms of hydrogen-induced phase transformations in materials for high-temperature applications, including thermal energy storage and steelmaking. By improving our ability to understand, predict, and control high-temperature, hydrogen-induced phase transformations, this project will support efforts to develop materials for environmentally friendly energy applications and foster our nation's energy security.
