Mr. Kutsch has managed green energy research projects for Xcel Energy, in conjunction with NREL. He has led Plant and Equipment Optimization and integration programs for a consortium of ADM, Marathon Oil, North Development’s advanced-design Ethanol facility. The facility successfully integrated discrete systems and new standard operating procedures and new approaches to create the first closed loop, circular, ethanol energy system, greatly increasing operating efficiencies while eliminating nearly all waste streams.

While performing RD&D functions for Terrestrial Energy, Mr. Kutsch led programs on Molten Salt Nuclear Process Heat, techno-economic analysis of nuclear hydrogen, nuclear liquid fuels, and nuclear heat derived ammonia with Idaho National Laboratory. Mr. Kutsch was lead P.I. for the commercialization study of a sulfur acid hydrogen project with INL, Sandia Labs and Southern Company. He has helped manage nuclear fuel salts characterization studies at Argonne National Laboratory and the University of Wisconsin Madison.

He was a founder of Terrestrial Energy and developed the Integral Molten Salt Reactor (IMSR) and all supporting facilities designs. This work resulted in 4 patents for Terrestrial Energy, spanning novel pumps, to the first novel salt storage process in over 40 years.

He assisted in performance modeling of the IMSR and all nuclear island and balance-of-plant systems, including process heat specific applications, as well as defining requirements and properties that all Generation-IV MSR systems must have.

This Generation-IV definition work was carried on by Thorium Energy Alliance (TEA) as a public service benefiting the field of innovative molten salt reactor technology. TEA has been the main supporter of, and has successfully managed the American Nuclear Society ANS 20.2 Definition Writing Program to define Molten Salt Reactors and their Design and Safety Requirements. The ANS 20.2 draft has been finalized and is in the process of final balloting before being presented to AMSE to be codified into an international standard.

Mr. Kutsch has worked on critical materials supply chains, advanced nuclear issues and various industrial projects with stakeholders for over 20 years. He believes that industries can work cooperatively to achieve huge gains in efficiency and provide the world with sustainable abundance and prosperity.

He has also completed the development of six chemobiological natural products to TRL-6, demonstrating strong translational research capabilities. Boyd’s technical expertise spans Magic-Angle Spinning MRI, several X-ray diffractometry methods, and advanced extraction, preparative, and solid-state techniques, making him highly skilled in working with inorganic, transition-metal, and transuranic materials.

Beyond academia, Dr. Wai founded LCW Supercritical Technologies (2014) to commercialize supercritical-fluid–based “green” separations for environmental remediation and recycling valuable materials such as rare earths and precious metals from electronic waste. Bibliometric profiles attribute hundreds of publications and sustained impact in supercritical fluids, metal ion chemistry, and extraction science; prior affiliations noted in public profiles include Fudan University and Chung Yuan Christian University.

Dr. Pan previously served as a Senior R&D Chemist at LCW Supercritical Technologies, leading projects focused on sustainable metal recovery and advanced materials development. He is co-inventor on multiple international patents and author of 28 peer-reviewed publications, reflecting a strong record of scientific innovation.

Earlier, he was a Professor at Texas A&M University at Galveston, where his work advanced understanding of mercury cycling, estuarine chemistry, and seawater geochemical processes. His interdisciplinary research spans mineralogy, oceanography, analytical chemistry, and waste management, contributing key insights into contaminant behavior and transport in aquatic environments.

Mr. Anthony has advised major uranium companies and international organizations and is a recognized expert who has presented for the International Atomic Energy Agency. He previously founded Anthony Engineering Services and held multiple leadership roles at URI. He holds Bachelor’s and Master’s degrees in Engineering Mechanics from Penn State.
