Nathan Schroeder

R&D Mechanical Engineer


Nathan Schroeder is an R&D Mechanical Engineer working at the National Solar Thermal Test Facility (NSTTF). Nathan is involved in Gen 3 particle- based acquisition and controls systems. He has conducted over 200 hours of falling particle receiver test operation as part of the Generation 3 down selection process. Nathan is also involved in thermal energy storage and other concentrating solar technology research, including decarbonization of cement production.

In graduate school, Nathan focused on energy and thermal sciences with an emphasis on renewable energy and energy storage. He started his graduate research by modeling microgrid dispatch strategies for the Emera microgrid demonstration on Kirkland Air Force Base. An opportunity at the seminal facility for concentrating solar power research, the NSTTF, brought him to Sandia in 2019. Since then, Nathan has progressed from a graduate intern to member of the technical staff, and finally to senior member of the technical staff.

His non-work interests include skiing, gardening, pond building, bee keeping, and hiking.
