Summary: In this study, the solubility of carbon dioxide in aqueous diethanolamine solution was modeled using PC-SAFT and SAFT-HR equations of state. These equations were able to accurately reproduce the solubility data from over 350 experimental points, covering a wide range of variables including amine molar concentration, temperature, carbon dioxide partial pressure, and carbon dioxide loading. PC-SAFT and SAFT-HR equations were also used to model ternary systems consisting of water, carbon dioxide, and diethanolamine using the bubble pressure algorithm. The results showed that PC-SAFT was more reliable with an overall average relative deviation of 4.374% compared to 45.452% for SAFT-HR, indicating its robustness in predicting the solubility of carbon dioxide in aqueous alkanolamine solutions.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
