Fossil fuel utilization as an energy resource is the main cause of CO2 emission; therefore, a new energy economic concept is required to achieve carbon neutrality to mitigate climate change impacts. Here, we propose a green-alcohol (green-ol) economy wherein green-ol, a major chemical used in CO2 recycling, can serve as fuel for land (e.g. ethanol) and air transport (e.g. butanol), and as a liquid organic hydrogen carrier (LOHC, e.g. methanol) for green hydrogen. The essential and triggering step in the green-ol process is an e-chemical process wherein CO2 is directly electrolyzed by clean net-zero electricity. Moreover, two important technologies, green-ol production from CO2 and dehydrogenation of green-ol, are reviewed and their challenges and limitations are discussed with the aim of building an achievable green-ol economy.
