Description
The emission of carbon dioxide (CO2) resulting from the combustion of fossil fuels has played a significant role in global warming, leading to increased risks of hazards and disasters compounded by climate change. To address these challenges, it is crucial to develop a new energy economic paradigm that can achieve carbon neutrality and mitigate the impacts of climate change. In this study, we propose an innovative concept known as the "green-alcohol" (green-ol) economy, which leverages green-ol—a key chemical in CO2 recycling—as a versatile fuel for both land transportation (e.g., ethanol) and air transportation (e.g., butanol), as well as a liquid organic hydrogen carrier (LOHC, e.g., methanol) for green hydrogen production. The cornerstone of the green-ol process lies in the electrochemical conversion of CO2 through direct electrolysis, utilizing clean net-zero electricity. Additionally, we provide a comprehensive review of two critical technologies: green-ol production from CO2 and the dehydrogenation of green-ol. We discuss the challenges and limitations associated with these technologies, aiming to establish a feasible pathway toward realizing a sustainable green-ol economy.
