Renewable methanol production from green hydrogen and captured CO2: A techno-economic assessment

A molecular view of single-atom catalysis toward carbon dioxide conversion

“…As one of the simplest liquid energy storage compounds and versatile C 1 building blocks, methanol has been appealing in both chemical and energy sectors over the past few decades, whose production from CO 2 hydrogenation has been considered to be a solution for excessive CO 2 emission and contribute to 'carbon neutrality'. 57,[113][114][115][116] The initial studies on the methanol synthesis from CO 2 were originated from the conversion of syngas consisting of CO, CO 2 and H 2 , which is mainly acquired through coal gasication, natural gas reforming and biomass transformation. The commercial production of methanol from CO 2 is generally realized with the utilization of copper-based catalysts, particularly those based on copper, zinc oxide and alumina (Cu/ZnO/Al 2 O 3 ).…”

Modified Cu–Zn–Al mixed oxide dual function materials enable reactive carbon capture to methanol

“…20 Reducing the cost and energy requirements of CO 2 to MeOH are needed to decarbonize and defossilize MeOH for the fuel and chemical industries. 21 To this end, RCC to MeOH has been reported to have the potential to reduce capital costs and energy requirements by about 50% when compared to separate CO 2 capture and conversion. 10 The key results of that case study are highly dependent on the development of materials and processes that have CO 2 capture capacities and MeOH yields that are comparable and competitive to a separate capture and conversion system.…”

Valorization of refinery flue gas through tri‐reforming and direct hydrogenation routes

“…This post-combustion carbon capture technology has been adopted as it is the traditional method and widely deployed in various sections of the refineries. [7,8] In order to valorize the captured CO 2 , two methodologies have been proposed, and their efficacies have been assessed towards meeting the objective of CO 2 valorization.…”

“…This can ensure a lower carbon footprint, leading to an environment-friendly process. Direct hydrogenation is a promising technology for transforming CO 2 into valuable chemicals [7,8] as it is a one-step process that can operate at moderate temperatures and pressures, resulting in a lower energy demand than traditional carbon capture and utilization methods. [16,17] A detailed feasibility study and parametric analysis on CO 2 hydrogenation via various catalysts has been presented by García-Hurtado et al, [18] Pietro et al, [19] Marcos et al, [20] and Frei et al [21] In this analysis, the hydrogen stream required in the hydrogenation process has been produced via an electrolysis unit powered by renewable energy, such as wind electricity.…”
