Scott Hsu

Fusion Partner at Lowercarbon Capital

Scott recently accepted the role of Fusion Partner at Lowercarbon Capital, where he focuses on supporting Lowercarbon’s portfolio fusion companies, helps source and deploy new fusion investments, and works to build partnerships and forge an enabling environment for the entire fusion-commercialization ecosystem.

Prior to joining Lowercarbon, Scott worked at the U.S. Department of Energy (DOE). From 2022–2025, he was Senior Advisor and Lead Fusion Coordinator in the DOE Office of the Under Secretary for Science and Innovation, where he led a crosscutting DOE team in developing a DOE-wide strategy to accelerate fusion commercialization. During this time, Scott was also the key DOE point-of-contact working with the White House Office of Science and Technology Policy (OSTP) in advancing U.S. Government interagency fusion policy, as well as the chief architect of the DOE Milestone-Based Fusion Development Program. From 2018–2022, Scott was a Program Director at ARPA-E, where he launched and managed over $100 million of fusion R&D programs and projects. Prior to DOE, Scott was a research scientist at Los Alamos National Laboratory (2002–2019), where he led experimental research spanning magnetic, magneto-inertial, and inertial confinement fusion. Scott is author or co-author of 85+ peer-reviewed publications, a Fellow of the American Physical Society (APS), and a co-recipient of the 2002 APS Award for Excellence in Plasma Physics Research. Scott has testified as an expert witness in three Congressional hearings on fusion energy (2016, 2022, 2023).

Scott earned a Ph.D. in Astrophysical Sciences (Program in Plasma Physics) from Princeton University and a B.S summa cum laude in Electrical Engineering from UCLA.
