The chemical industry must become carbon neutral by 2050, meaning that process-, energy-, and product-related CO 2 emissions from fossil sources are completely suppressed. This goal can only be reached by using renewable energy, secondary raw materials, or CO 2 as a carbon source. The latter can be done indirectly through the bioeconomy or directly by utilizing CO 2 from air or biogenic sources (integrated biorefinery). Until 2030, CO 2 waste from fossilbased processes can be utilized to curb fossil CO 2 emissions and reach the turning point of global fossil CO 2 emissions. A technology mix consisting of recycling technologies, white biotechnology, and carbon capture and utilization (CCU) technologies is needed to achieve the goal of carbon neutrality. In this context, CHEMampere contributes to the goal of carbon neutrality with electricity-based CCU technologies producing green chemicals from CO 2 , N 2 , O 2 , and H 2 O in a decentralized manner. This is an alternative to the e-Refinery concept, which needs huge capacities of water electrolysis for a centralized

“…The electrocatalytic conversion of CH 4 to a C 2 hydrocarbon in H + conductors was well studied by Stoukides’ group, and the results were presented in a series of publications. ,− In ref , the group used three different electrolyte cell reactor configurations: a single-chamber Ag/SCYb/Ag, a single-chamber Ag/YSZ/Ag, and a double-chamber Ag/SCYb/Ag (Figure ). The two-chamber cell was used to measure the electrolyte H + conductivity and to serve as a membrane to separate hydrogen from C 2 products, and the cell in one chamber was tested as a simpler design.…”

Direct conversion of methane to C2 compounds by oxidative and nonoxidative coupling reactions has been intensively studied in the past four decades; however, because these reactions have intrinsic severe thermodynamic constraints, they have not become viable industrially. Recently, with the increasing availability of inexpensive “green electrons” coming from renewable sources, electrochemical technologies are gaining momentum for reactions that have been challenging for more conventional catalysis. Using solid-state membranes to control the reacting species and separate products in a single step is a crucial advantage. Devices using ionic or mixed ionic–electronic conductors can be explored for methane coupling reactions with great potential to increase selectivity. Although these technologies are still in the early scaling stages, they offer a sustainable path for the utilization of methane and benefit from the advances in both solid oxide fuel cells and electrolyzers. This review identifies promising developments for solid-state methane conversion reactors by assessing multifunctional layers with microstructural control; combining solid electrolytes (proton and oxygen ion conductors) with active and selective electrodes/catalysts; applying more efficient reactor designs; understanding the reaction/degradation mechanisms; defining standards for performance evaluation; and carrying techno-economic analysis.
