Josh McTigue is a research engineer in the Thermal Sciences Group at NREL. Currently, his research concentrates on an electricity storage system known as Pumped Thermal Electricity Storage (PTES) or a Carnot Battery. He is also interested in developing techno-economic models of hybrid energy systems which integrate geothermal power, concentrating solar power and thermal energy storage. For his graduate work, Josh researched PTES and packed-bed thermal storage with an emphasis on exergy analysis and system design and optimization. His expertise lies in heat transfer, thermodynamics, and optimization techniques.
Josh received his PhD and M.Eng in Mechanical Engineering from the University of Cambridge, UK.
