Pengfei Cheng, David M. Thierry, Howard Hendrix, Katherine D. Dombrowski, Darshan J. Sachde, Matthew J. Realff, Joseph K. Scott IN: Applied Energy 341, 121076, https://doi.org/10.1016/j.apenergy.2023.121076
Recently, the authors proposed a retrofit design for an existing NGCC (Natural gas combined cycle plant) to allow power generation with negative emissions by utilizing both post-combustion carbon capture (PCC) and direct air capture (DAC). The DAC unit captures directly from the atmosphere using low-grade heat from the NGCC via a novel heat integration scheme. In this work, the autors model the proposed retrofit systematically and co-optimize the design and operation of the system for an entire year under different electricity price signals and prices.
