This paper evaluates the technological trends in the carbon sequestration process. For this purpose, these systems have been classified into two subsystems: conventional technologies subsystem and emerging technologies subsystem. Each is explored for its suitability for meeting a set of six attributes. A bibliometric analysis process was developed using the Scopus database and VOSviewer Software to present the potential of each subsystem evaluated, through an evaluation matrix. The analysis of the subsystems and attributes was performed through the formal concept analysis methodology (8FCA). To facilitate the processing of the information, the open access software concept Explorer was used. The analysis shows that conventional technologies, despite their cost, will be maintained and advance in their implementation process. The bibliometric analysis integrated with the applied FCA methodology has proven to be useful for the evaluation of technological typologies and serves as an alternative to develop theoretical studies that group and link different options as a model to evaluate a deterministic set of attributes.

“…Some researchers have combined conventional MSR processes with solar thermal technologies, by which it is possible to address both challenges of high energy penalty in the conventional MSR process and of the spatial and temporal availability of solar energy [12,43]. The AE-MSR method operates at a temperature of 200 • C, which matches the temperature of a low-concentration (~80x) solar parabolic trough collector [44]. Compared with tower or dish type solar collectors, parabolic trough solar collectors are considered the most commercial and economical approach for concentrated solar energy conversion and utilization [45].…”

Methanol is a prospective hydrogen storage medium that holds the potential to address the challenges of hydrogen storage and transportation. However, hydrogen production via methanol steam reforming faces several key obstacles, including high reaction temperature (e.g., 250–300 °C) and low methanol conversion (at <200 °C), while the purification procedure of hydrogen is commonly required to obtain high-purity H2. A novel method of H2 absorption-enhanced steam reforming of methanol is proposed to overcome the challenges mentioned above. The method involves the absorption and separation of H2 using an absorbent to facilitate the forward shift of the reaction equilibrium and enhance reaction performance. A thermodynamic analysis using the equilibrium constant method presents that the separation of H2 can improve the methanol conversion rate and the total H2 yield. The feasibility of the method is validated through experiments in a fixed-bed reactor (4 mm diameter, 194 mm length) under the conditions of 200 °C and 1 bar. In the experiments, 1 g of bulk catalyst (CuO/ZnO/Al2O3) and 150 g of bulk hydrogen absorbent (Aluminum-doped lanthanum penta-nickel alloy, LaNi4.3Al0.7 alloy) are sequentially loaded into the reactor. As a proof of concept, a CO2 concentration of 84.10% is obtained in the reaction step of the first cycle, and a gas stream with an H2 concentration of 81.66% is obtained in the corresponding regeneration step. A plug flow reactor model considering the kinetics is developed to analyze the effects of the number of cycles and H2 separation ratio on the enhancement performance. The method indicates a high potential for commercialization given its low reaction temperature, high-purity H2, and membrane-free design.
