| contents | In the global pursuit of sustainable energy solutions, mitigating carbon dioxide (CO2) emissions stands as a pivotal challenge. With escalating atmospheric CO2 levels, the imperative of direct air capture (DAC) systems becomes evident. Simultaneously, green hydrogen (GH) emerges as a pivotal medium for renewable energy. Nevertheless, the substantial expenses associated with these technologies impede widespread adoption, primarily due to significant installation costs and underutilized operational advantages when deployed independently. Integration through sector coupling enhances system efficiency and sustainability, while shared power sources and energy storage devices offer additional economic benefits. In this study, we assess the economic viability of polymer electrolyte membrane electrolyzers versus alkaline electrolyzers within the context of sector coupling. Our findings indicate that combining GH production with solid DAC systems yields significant economic advantages, with approximately a 10% improvement for PEM electrolyzers and a 20% enhancement for alkaline electrolyzers. These results highlight a substantial opportunity to improve the efficiency and economic viability of renewable energy and green hydrogen initiatives, thereby facilitating the broader adoption of cleaner technologies. |
