Mohan et al. (2024): Direct air capture integration with low-carbon heat: Process engineering and power system analysis
Aniruddh Mohan, Fangwei Cheng, Hongxi Luo, Chris Greig, Eric Larson, Jesse D. Jenkins IN: Energy Conversion and Management, 322, 119136, https://doi.org/10.1016/j.enconman.2024.119136
Here, the authors undertake a unique interdisciplinary study combining process engineering with a detailed macro-energy system optimization model to evaluate the system-level impacts of such plant designs in the Texas electricity system. They contrast this with using grid power to operate a heat pump to regenerate the sorbent. The analysis identifies net carbon removal costs accounting for power system impacts and resulting indirect CO2 emissions from DAC energy consumption.
