Hi! I’m Claire Halloran (they/them), an energy system modeler specialized in sector-coupling applications and electricity demand changes. I model the electricity system to provide decision-makers insight into how policies and technologies could shape its future. I am currently a researcher on the capacity expansion team in the Grid Planning and Analysis Center at the National Laboratory of the Rockies (formerly the National Renewable Energy Lab (NREL)), where I work on a project portfolio focused on electricity demand changes, including data center demand growth and geothermal heating and cooling.As a doctoral candidate in energy systems engineering at the University of Oxford Energy and Power Group funded by the Rhodes Scholarship, I incorporated spatially granular heating data into electricity system planning models to assess the impact that residential heat pump deployment will have on the electricity system. As a part-time research assistant in the Climate Compatible Growth program, I developed an open-source geospatial planning tool to optimize green hydrogen production and transport. I’m also a bit of a map nerd and enjoy communicating with policymakers and general audiences about my research. Before starting my PhD, I earned my Bachelor’s in Materials Science and Engineering at MIT.
