“…Replacing the combustion heat in conventional fuel fired reformers with electrification is regarded as a very promising solution, also when considering the economically competitive prices of the renewable electricity compared with fossil fuels. − Process simulation results from different studies show that the novel electrified methane steam reforming process is of great interest from energy, environmental and economic point of view. ,,− The specific power consumption per hydrogen production estimated for electrified methane steam reforming (approximately 1 kWh/Nm 3 H2 considering only electric input) is remarkably lower than that in water electrolyzers (3.8–4.5 kWh/Nm 3 H2 ). , It should be noted that approximately 4% of the world’s hydrogen is derived from water electrolysis, whereas conventional methane steam reforming contributes to over 70% of the global hydrogen production . In this regard, the recent developments in direct Joule heating of methane reforming reactions are reviewed, as shown in Table .…”

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.
