Decision-support for Low-carbon Integrated Energy Systems

The existing infrastructures for the electric power and transportation sectors, which collectively accounted for ~69% of energy-related CO2 emissions for the U.S. in 2019, evolved nearly independently over the past century and entail significant under-utilization of capital-intensive assets (e.g. personal automobiles, distribution networks, peaking power plants). With recent advances in digitization and modular technologies for energy generation, conversion and storage, there is an opportunity to design and operate energy infrastructure to serve multiple end uses in an integrated manner. An integrated vision must not only consider cost savings and emissions impacts from sharing infrastructure but also overall resiliency to demand or supply disruptions caused by climate change or other risks.In our research, we develop and apply mathematical models to study planning and operation of integrated energy systems and resulting technology, market and policy implications. We draw upon insights developed from the literature on power system planning and operations and extend it to study broader energy system, which includes dynamic interactions between the electric grid and other end-use sectors as well as roles for other energy vectors like hydrogen.
