The Concentrating Solar-Thermal Power (CSP) team supports the development of novel CSP technologies that help to lower costs, increase efficiency, and provide more reliable performance relative to current CSP technologies. This team supports research and development that advances Generation 3 CSP technologies, which utilize high-temperature components and integrated assembly designs with thermal energy storage that can reach operating temperatures greater than 700 degrees Celsius. The team also works to advance new applications for the technology, from solar desalination to thermal industrial processes.

Matthew Bauer

Dr. Matthew Bauer is a technology development manager for the Solar Energy Technologies Office (SETO) Concentrating Solar-Thermal Power (CSP) team. Since 2015 he has worked with the CSP research and development (R&D) community to identify promising CSP-relevant technologies and solve technical risks impeding such technologies from commercial adoption. While primarily focused on CSP for electricity generation, Matthew also develops frameworks for technology advances in related applications including pumped thermal energy storage, solar thermal process heat, and solar thermochemical processes. Recently, he has headed SETO’s 2019  FIRM Thermal Energy Storage initiative, SETO’s 2018 Advanced Components R&D initiative, as well as the CSP program’s reoccurring seedling research initiative, Small Innovative Projects in Solar (SIPS), and parallel National Laboratory Research.

Analysis of viable system concepts where new technologies can be deployed has been an area of focus for Matthew, including: higher temperature molten salt systems, first of a kind integrated particle CSP systems, and integrating CSP with sCO2 power cycles.  Matthew’s research background is focused on microscale thermal transport phenomena- theory,  measurements, and simulations. Prior to joining SETO, Matthew completed his Ph.D. in Mechanical Engineering at the University of Virginia.
