英文摘要	As scientists and engineers studying CO2 conversion technologies, it is important to understand the CO2-derived methods of production for critical basic chemicals, and renewable alcohol production is one of the few CO2 utilization technologies deployed at industrial scale. Alcohols are building blocks for materials that we encounter every day; and among alcohols, methanol is a critical chemical intermediate for the production of polymers, plastics, fibers, and resins and holds promise as a potential renewable liquid fuel. At present, most methanol is produced using natural-gas-derived syngas. Its alternative production using CO2, water, and renewable electricity presents an opportunity to advance entire industries toward carbon neutrality. By analyzing its current stage of development, this perspective presents research and development goals to further utilize CO2 conversion to methanol technologies. Working together toward these goals, we can advance humanity toward the implementation of carbon-neutral alcohols and low-carbon fuel. © 2020 Elsevier Inc.Technologies that produce renewable alcohols from CO2 have the potential to significantly reduce global greenhouse gas emissions but are not widely adopted. In this perspective, we compare CO2 electrolysis and CO2 hydrogenation for industrial production of methanol from CO2 and their potential for global deployment. We provide an overview of current commercial deployments and evaluate technoeconomic analyses in literature to guide future research and development. Analysis of markets for methanol-derived products further provides practical avenues for implementation, driven by economics. © 2020 Elsevier Inc.Production of renewable alcohols from air, water, and sunlight present an avenue to utilize captured carbon dioxide for the production of basic chemicals and store renewable energy in the chemical bonds of liquid fuels. Of the technologies that utilize CO2 directly, CO2 electrolysis, as well as CO2 hydrogenation coupled with H2O electrolysis, have the benefit of requiring only CO2, H2O, and renewable electricity as inputs with O2 as a sole byproduct. Among alcohols, renewable methanol has seen the most development and analysis in the chemical industry because it is currently a syngas-derived product that could be adapted for direct CO2 utilization. In this perspective, we compare renewably powered CO2 electrolysis and CO2 hydrogenation with the incumbent methanol production method from syngas from a cost and CO2 life cycle perspective by analyzing recent literature to identify the research goals that enable further scale-up. Survey of the industry shows that CO2 hydrogenation is among the closest CO2 utilization technologies to large-scale deployment. We further discuss these CO2 hydrogenation systems and the catalysts that drive them, with recommendations to drive further development and scale-up. © 2020 Elsevier Inc.
