Electrolyser stack The electrolyser was modelled according to the description in Section S2.1. It was first scaled-up to 2 m2, which is the area of the electrode in an advanced large-scale alkaline electrolyser, as described in Koj et al. (2015). The process for scaling the inventory requirements is described in Section S1.2.1 and

Sep 13, 2023 · The aim of this study is to understand the effects of the GDE structure on flooding behavior and CO2 reduction performance. We approach the problem by preparing GDEs from commercial substrates with a range of structural parameters …

CO 2 electrolysers can use (renewable) electricity to reduce the waste gas stream to useful products such as CO, CH 4 and C 2 H 4 at the cathode and water oxidation to produce O 2 at the anode also occurs.

Jan 11, 2024 · Carbon dioxide (CO 2) fixation into value-added solid carbon such as carbon nanofibres (CNF) for longer-term storage represents a promising avenue for achieving net-negative carbon emissions.

May 12, 2022 · In this Review, we analyse the literature on four emerging high single pass CO 2 conversion approaches: CO 2 regeneration from carbonate, CO 2 R in acidic media, cascade CO 2 R-COR and CO 2 R...

Nov 13, 2024 · Electrochemical CO 2 reduction has emerged as a promising CO 2 utilization technology, with Gas Diffusion Electrodes becoming the predominant architecture to maximize performance. Such electrodes...

Dec 15, 2022 · Combining wet papermaking, thermal carbonization, and double activation, the new strategy enables the in-situ transformation of fibrillated pulp fibers into cellulose-derived activated carbon fused with carbon fibers (CFs).

Sep 27, 2024 · Our idea is to wrap the electrolyser in a high-pressure vessel of carbon fibre-reinforced polymer, which is typically used for high pressure hydrogen storage tanks in the automotive industry.

Gas-fed CO 2 electrolysers are a leading remedy to the solubility problem, where the CO 2 is introduced to the cell in gas phase. Such an approach can be implemented using gas diffusion electrodes (GDEs). GDEs are porous electrodes with a …

Aug 9, 2024 · Carbon capture and utilization technologies offer an additional decarbonizing path that recycles atmospheric and industrial CO 2 into widely used carbon-based chemicals, which are today obtained from fossil fuels (Figure 1a).
