Liang Min – Smart Grid, Renewable Energy Integration and Power Storage

Liang Min is the Grid Operations Leader in LLNL’s National Security Engineering Division. He joined LLNL in November 2011 and specializes in research on developing computation methods for the solution of power system operations and applying probabilistic methods to power system planning. In addition, he is dedicated to developing new techniques and methodologies that enable reliable and efficient grid operations by integrating renewable generation and demand options into planning for a carbon-constrained world.

Prior to LLNL, Liang worked at the Electric Power Research Institute (EPRI) as a Senior Project Manager in the renewable integration, grid operations and planning program. He also led the grid operations research area and managed a team of project managers and contractors charged with delivery of more than 20 projects a year. Liang worked as sub-recipient and EPRI lead of the Entergy’s DOE smart grid project, using synchrophasors to assess voltage stability. For the New York State Energy Research and Development Authority, he managed smart grid research projects related to synchrophasors and sensor technologies applications to grid operation.

Liang received a B.S. and M.S. degree in electrical engineering from China’s Tianjin University and a Ph.D. from Texas A&M University. He has published numerous papers in journals and conference proceedings and has served as a panelist and invited speaker in various industry forums. He holds two U.S. patents in the area of measurement based voltage stability assessment.

Nalu Kaahaaina – Combustion of Liquid Fuels


Nalu manages the Laboratory’s low-carbon energy portfolio and is responsible for energy-related program development and strategic planning. The low-carbon portfolio emphasizes energy technologies—including combustion and engine research—and techno-economic analysis in support of both government and industrial sponsors. Prior to joining LLNL, Nalu was the Deputy Director of the Advanced Energy Systems Laboratory at Stanford University, where he led research on experimental homogeneous charge-compression ignition (HCCI) engines. These HCCI experiments involved such cutting-edge innovations as in-cylinder injection and camless valve actuation using a multitude of fuels on several engine architectures. Nalu also concurrently served as a lecturer in Stanford’s Mechanical Engineering Department, teaching undergraduate courses in internal combustion engines and thermal systems.

Nalu also worked as a consultant for the technology and innovation practice of Arthur D. Little (later acquired by TIAX, LLC), where he specialized in transportation technology, principally in the automotive sector. Nalu has also consulted for early-stage venture capital firms and startup companies in clean technologies, focusing on identifying the technical performance needed to unlock improvements in energy systems as a means for evaluating the direction and consequence of proposed innovations. In graduate school, Nalu designed an engine laboratory from the ground up, featuring 10,000 square feet of facilities for liquid and gaseous combustors; reciprocating engines; and pulse-detonation experiments. The preliminary design was completed in six months and the facility was constructed in three years. He is a member of ASME (founded as the American Society of Mechanical Engineers) and the Society of Automobile Engineers.

S. Julio Friedmann – Carbon Capture, Utilization and Sequestration


Julio is one of the most widely known and authoritative experts in the United States on carbon capture and sequestration (CCS) and underground coal gasification. In his current appointment as Chief Energy Technologist for Lawrence Livermore National Laboratory, he leads initiatives and research in carbon capture and storage and fossil fuel recovery and utilization. This includes research, development and technology assessment in shale gas; hydrofracturing; conventional and unconventional oil recovery; carbon dioxide-enhanced oil recovery; and underground coal gasification. In this role, he has testified before the U.S. House and Senate and several state legislatures; published in Foreign Affairs and the New York Times; and worked with many private companies and government agencies. He has worked closely with the U.S. Deparment of Energy and Environmental Protection Agency, as well as the U.S. Energy Association. He is a principle co-author of the MIT report The Future of Coal Energy, the National Petroleum Council report Facing Hard Truths and the World Resources Institute report Carbon Capture and Sequestration CCS Guidelines.

Julio has led technical work for large CCS projects in the United States (such as In Salah and Weyburn) and in China. He is currently the co-director for the U.S.–China Clean Energy Research Center on Clean Coal and CCS and serves on the technical advisory boards for CCS projects by American Electric Power, Summit Power, EmberClear, and GreatPoint Energy. Julio has B.S and M.S. degrees from the Massachusetts Institute of Technology and a Ph.D. from the University of Southern California. After graduation, he worked as a senior research scientist at Exxon and later ExxonMobil, then as a research scientist at the University of Maryland, collaborating with the university’s Joint Global Change Research Institute and the Colorado Energy Research Institute at the Colorado School of Mines.

Tom Arsenlis – Nuclear Energy and Materials


Tom concurrently leads the High-Performance Computational Materials Science Group and the Advanced Strategic Computing Constitutive Properties Program Element at Lawrence Livermore National Laboratory. He has two B.S. degrees from Cornell University—in mechanical and aerospace engineering and materials science and engineering—and a Ph.D. in mechanical engineering from the Massachusetts Institute of Technology. His awards include a National Defense Science and Engineering Graduate Fellowship from the Department of Defense.

Tom’s research has been at the forefront of using advanced computational capabilities to understand the behavior of nuclear materials. For instance, he has gained new insight into dislocation dynamics and how nuclear materials deform and fail by combining advances in supercomputing with materials experimentation and characterization. His many publications encompass a wide range of nuclear material aspects, such as ultra-deep-burnup, the x-ray diffraction of crystalline materials under high pressure, modeling material strength for high-energy-density physics, investigating dislocation patterning (including the visualization of simulations) and understanding dislocation interactions with radiation-induced defects. Tom also holds a patent relating to nuclear fuel.

Noah Goldstein – Building Energy Efficiency


Noah Goldstein is a spatial scientist in LLNL’s Engineering Directorate, as well as the Laboratory’s Scientific Lead for Site Sustainability. He has a B.A. in biology from the University of California (UC) at Santa Cruz and an M.A. and Ph.D. in geography from UC Santa Barbara. He is an Accredited Professional under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program.

Noah completed his graduate and postgraduate research at LLNL, where he currently focuses on energy systems informatics, validating energy efficiency, understanding the energy–water nexus, modeling spatial energy demand and quantifying sustainability measures in the built environment. Noah also worked in the sustainable building field, focusing on building energy simulation and green building rating systems. His involvement in building efficiency ventures includes creating a green building portfolio assessment program for real estate portfolio owners and managers to quantitatively improve the sustainable performance and operations of their buildings and creating a software tool for assessing green building companies.

Noah has more than 15 years of experience in environmental sustainability applied and theoretical research and has published peer-reviewed articles on energy informatics; zero-net-energy buildings; and simulations of human and natural systems. He has been instrumental in assisting a national laboratory extend its contract term through achievements in sustainability and developing projects with multiple new government and corporate sponsors in renewable energy, smart grid, wildfire analysis and low-carbon energy solutions. He also developed internal research projects that leverage R&D expertise to benefit on-site sustainability performance. Recently, he was the lead on building energy efficiency for the National Summit on Advancing Clean Energy Technologies and’s Incubator Program.
