The production of sustainable carbon-based products requires sustainable carbon feedstocks, such as CO2 from biogenic sources or the atmosphere. Due to the thermodynamic stability of CO2, its activation for chemical conversion is complex and potentially costly. In the reverse water–gas shift reaction (RWGS), CO is reduced to CO using hydrogen, whereby synthesis gas can be provided for downstream synthesis. This article examines the fundamentals of RWGS, reactor concepts, and integration into synthesis processes. The provision of thermal energy for adequate CO conversion and minimal methanation side reactions is of crucial importance. While fired RWGS reactors are used industrially, electrically heated reactors are still in the pilot stage.enCO activation 2 | Reverse Water–Gas Shift (RWGS) | Synthesis | Synthesis gasSocial Sciences::333: Economics of Land and Energy::333.7: Natural Resources, Energy and EnvironmentBook part10.1007/978-3-031-62411-7_19Other
