“…Driven by renewable energy, the direct electrification of catalytic processes through the Joule effect not only eliminates CO 2 emissions from fuel combustion but also provides the required heat for highly endothermic processes, as discussed previously for methane steam reforming (Section ), cracking processes (Section ), and CO 2 activation reactions (Section ). Furthermore, it enables fast and selective heating of the catalytic bed, making it particularly advantageous for applications where rapid heating is required. − On the other hand, the direct electrification of catalytic processes suffers from the intermittent nature of the renewable electricity supply, such as from sun and wind. This calls for high operational flexibility of the electrified reactors to sustain fast dynamics of the input energy supply.…”

The supply of the heat required for chemical processes via renewable electricity, i.e., process electrification, provides an alternative strategy for replacing conventional fossil fuel combustion. This approach enables fast, selective, and uniform heating, offers great potential for utilizing the excess renewable electric energy, and brings about an important chance for mitigating CO 2 emissions. In this work, we provide an overview of the state-of-the-art electricity-to-heat driven catalytic processes. The principle and fundamentals of Joule heating are provided and briefly compared to induction and microwave heating in view of electrifying catalytic processes. By this comparison, we assess that Joule heating can be regarded as the most promising method for process electrification, and its applications to methane reforming, cracking reactions, CO 2 valorization, and transient process operation are then reviewed. Advantages and disadvantages are critically addressed in terms of efficiency, potential for scale-up and possibility of retrofitting. The current challenges in the development of advanced electrified processes as well as the opportunities of next generation electrification techniques are discussed.
