“…Joule-heated CO 2 utilization processes based on renewable electricity may represent the technological solution to reduce the carbon footprint of chemical products in the near future, as suggested by process, environmental and economic calculations. 78,95 In this context, Wismann and co-workers reported for the first time the electrified RWGS process, 45 based on the same direct Joule heating of Ni-catalyst washcoated tube reactor configuration discussed in Figure 4. By employing an industrially relevant condition: H 2 /CO 2 feed ratio of 2.25 at 10 bar, a syngas with H 2 /CO ratio of 2 was obtained at 1050 °C, which was suitable for downstream Fischer−Tropsch synthesis.…”

“…However, as the only technology approaching commercialization, the solid oxide electrolyzer requires an specific energy demand as high as 6–8 kWh/Nm 3 CO2 . , On the other hand, CO 2 conversion processes into synthesis gas, such as dry reforming of methane or reverse water–gas shift (RWGS), may play a strategic role for the future sustainable production of chemicals and energy carriers. ,, On the other hand, fuel combustion to supply the heat of the associated endothermic reactions would result in unwanted CO 2 emissions, thus frustrating the overall objective.

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.

Biomass assumes an increasingly vital role in the realm of renewable energy and sustainable development due to its abundant availability, renewability, and minimal environmental impact. Within this context, 5‐hydroxymethylfurfural (HMF), derived from sugar dehydration, stands out as a critical bio‐derived product. It serves as a pivotal multifunctional platform compound, integral in synthesizing various vital chemicals, including furan‐based polymers, fine chemicals, and biofuels. The high reactivity of HMF, attributed to its highly active aldehyde, hydroxyl, and furan ring, underscores the challenge of selectively regulating its conversion to obtain the desired products. This review highlights the research progress on efficient catalytic systems for HMF synthesis, oxidation, reduction, and etherification. Additionally, it outlines the techno‐economic analysis (TEA) and prospective research directions for the production of furan‐based chemicals. Despite significant progress in catalysis research, and certain process routes demonstrating substantial economics, with key indicators surpassing petroleum‐based products, a gap persists between fundamental research and large‐scale industrialization. This is due to the lack of comprehensive engineering research on bio‐based chemicals, making the commercialization process a distant goal. These findings provide valuable insights for further development of this field.This article is protected by copyright. All rights reserved
