Biography

Dr. H. Evan Bush is an R&D, S&E Mechanical Engineer and Senior Member of the Technical Staff in the Concentrating Solar Technologies group. Evan’s research focuses on solar thermochemical cycles, materials, and reactors for thermal energy storage, H2 generation, and the production of chemical commodities such as ammonia. His research also includes the characterization and control of high-temperature particles for sensible energy transport and storage. Evan has worked on projects relating to CSP systems/technoeconomic modeling; solar reactor engineering and computational modeling; PV solar glint and glare prediction; CSP mirror characterization; and digital imaging and ray tracing to characterize high temperature, high flux systems.
