Considering the severe environmental issues brought by excessive carbon emissions, the utilization of CO2 as a feedstock for chemicals synthesis is gaining a lot of interest. CO2 hydrogenation into valuable chemicals using renewable energy is a promising strategy to alleviate the environmental pressures and reduce our strong dependence on fossil fuels simultaneously. Aromatics, as important chemicals in our daily life, can be synthesized by a tandem strategy that first converts CO2 into CO or methanol on Fe‐based active sites or reducible metal oxides, respectively, and then sequentially conducts CC coupling, dehydrogenation, and cyclization processes on acidic zeolites with unique topology structure for aromatics synthesis. This critical review focuses on the recent advancements in CO2 hydrogenation into high value‐added aromatics (CTA), in particular the key factors, such as the catalytic component, the acidity distribution of the zeolite, and the proximity effect between different active sites that regulate the aromatics selectivity. The reaction network and mechanism during the tandem process will be discussed to guide the rational design of highly efficient bifunctional/multifunctional catalysts for direct synthesis of aromatics by CO2 hydrogenation. Furthermore, the development directions and obstacles of CO2 utilization by hydrogenation technology will be predicted to pave the way for the practical application of greenhouse gas CO2 for valuable aromatics synthesis.

“…Electrical energy is converted into hydrogen through electrolyzed hydrogen production equipment, and hydrogen is delivered to the hydrogen application terminal or it can be integrated into the grid via fuel cells to complete the conversion from renewable energy to hydrogen energy. According to the source of electrical energy, renewable hydrogen technology can be divided into two types: grid-connected and off-grid hydrogen production (Nguyen et al., 2019). Grid-connected hydrogen production is a method of generating electricity by connecting the generator set to the power grid and taking power from the power grid, such as taking power from the grid side of the wind-solar coupling system to produce hydrogen by electrolyzing water, which is mainly used for the dissipation of large-scale wind-solar coupling systems.…”

“…for the EU's Fuel Cell and Hydrogen Joint Undertaking (FCHJU) ( Bertuccioli et al, 2014 ). However, most recent studies have mainly focused on analyzing single electricity supply configuration (grid powered or either solar or wind) ( Ayodele and Munda, 2019 ; Jiang et al, 2019 ; Nguyen et al, 2019 ) or single electrolyzer technology (alkaline electrolyzer [AE] or proton-exchange membrane electrolyzer [PEM]) ( Lee et al, 2017 ; de Fátima Palhares et al, 2018 ), by either analyzing the economics of proposed hypothetical electrolyzer designs ( Vincent et al., 2017 ; Vincent and Bessarabov, 2018 ; Taner et al., 2019 ) or optimizing the electrolyzer for a specific application with assumed capacity factors ( Abdin and Mérida, 2019 ; Kong et al, 2020 ; Micena et al, 2020 ).

Designing optimal integrated electricity supply configurations for renewable hydrogen generation in Australia

Summary The high variability and intermittency of wind and solar farms raise questions of how to operate electrolyzers reliably, economically, and sustainably using predominantly or exclusively variable renewables. To address these questions, we develop a comprehensive cost framework that extends to include factors such as performance degradation, efficiency, financing rates, and indirect costs to assess the economics of 10 MW scale alkaline and proton-exchange membrane electrolyzers to generate hydrogen. Our scenario analysis explores a range of operational configurations, considering (i) current and projected wholesale electricity market data from the Australian National Electricity Market, (ii) existing solar/wind farm generation curves, and (iii) electrolyzer capital costs/performance to determine costs of H 2 production in the near (2020–2040) and long term (2030–2050). Furthermore, we analyze dedicated off-grid integrated electrolyzer plants as an alternate operating scenario, suggesting oversizing renewable nameplate capacity with respect to the electrolyzer to enhance operational capacity factors and achieving more economical electrolyzer operation.
