Integrating solid direct air capture systems with green hydrogen production: Economic synergy of sector coupling

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 operationa...
