Hydrogenation of CO2 is a promising way for CO2 utilization due to the possibility of producing a wide range of chemicals including CO, CH4, value-added hydrocarbons and oxygenates. Plasma technology, especially plasma-catalysis, has great potential for the valorisation of CO2 and has attracted much attention in recent years. The technological development in renewable energy and clean hydrogen production facilitates the research in plasma-assisted hydrogenation of CO2 as a green approach for chemical production and energy storage. As a result, there is growing interest in this field and a rapid increase in related research can be expected in the near future. Therefore, it is worthwhile to discuss the development of this technology along with current research gaps. This chapter presents a comprehensive review of research progress in plasma and plasma-catalytic CO2 hydrogenation with a focus on DBD plasma reactors and different catalysts. The status and potential challenges of CO2 methanation as well as the production of methanol and CO are covered. Both the plasma-induced gas phase and surface reaction pathways have been discussed to provide insights of the reaction mechanism. Finally, recommendations of potential directions for future research are given.
