“…In general, the absorption ability of the solvent for CO 2 mainly depends on its own properties, which are related to the specific functional groups and can also be explained by the similarity and intermiscibility theory. According to Deanda et al, 30 the dissolution of the gas in the physical solvent needs to break the interaction between the solvent molecules, forming a cavity between the solvent molecules to accommodate the gas molecules, and then the gas molecules enter the cavity and reinteract with the solvent. Therefore, the amount of the abovementioned cavity determines the absorption ability of the solvent for the formation of CO 2 .…”

Ketone solvents have been considered as potential absorbents for the coal-based syngas purification process. However, their vapor–liquid equilibrium (VLE) data with CO2 at low temperatures are insufficient. Therefore, in this study, acetone, butanone, 2-pentanone, and 3-pentanone were used as the absorbents, and their VLE data with CO2 were measured via a static method at 253.15 K. Subsequently, the Soave–Redlich–Kwong (SRK) and Peng–Robinson (PR) equations of state combined with the van der Waals (vdW) mixing rule and the Mathias–Klotz–Prausnitz (MKP) mixing rule were used to correlate the obtained experimental data, respectively. The correlation effects of different models were compared through the absolute average relative deviations between the experimental and calculated values of the molar fraction of CO2 in the vapor phase and system pressure. The results show that the average absolute relative deviations between the experimental and the calculated values for all models were less than 3.2%, which indicates the calculated values have a good correlation with the experimental values. Among them, the MKP mixing rule has better correlation effects of the CO2 + ketone systems than the vdW mixing rule. In addition, acetone has the best absorption capacity for CO2, followed by butanone, 2-pentanone, and 3-pentanone at the same experimental temperature and pressure. Overall, this study provides important basic thermodynamic data to design and develop cleaner and more sustainable syngas purification processes.

“…Therefore, it is essential to understand the diffusion kinetics of hydrogen within cement materials because it is one of the key factors influencing the leakage tendency of hydrogen. 68 Several studies have investigated the diffusivity of hydrogen in gases, brines, and different rock formations at various experimental conditions. 69 For instance, it was observed that the diffusivity of hydrogen in gases decreases with the pressure increase; 5,70,71 however, hydrogen diffusivity in water increases with an increasing temperature and pressure.…”

Underground hydrogen storage (UHS) is a promising solution to meet the increase in energy supply and demand while supporting the energy transition to net-zero carbon. The successful implementation of UHS requires careful assessment of several scientific aspects, among them evaluating the cement stability and wellbore integrity to ensure safe storage and production of hydrogen. Few studies have evaluated the geochemical reactivity of cement to hydrogen; however, more studies are needed to explore the role of hydrogen adsorption and diffusivity behavior with cement and address the associated wellbore integrity issues. This minireview presents the state-of-the-art advancement in evaluating the impact of hydrogen on cement wellbore stability from various aspects, including hydrogen/ cement interactions, hydrogen adsorption and diffusivity, current methodologies, experimental setups, and the role of cement additives and cushion gases. This minireview provides a general comparison between UHS and other gas storage applications and mainly aims to bridge the knowledge gap by providing insights for practical implementations, challenges, and future directions relevant to wellbore integrity. Although most of the reviewed studies reported a low impact of hydrogen injection on cement stability, the successful implementation of UHS requires further assessment as various technical and non-technical factors and mechanisms are involved. Systematic scientific studies should be performed in the future, which will assist in overcoming the existing challenges and reducing the uncertainty associated with wellbore integrity during UHS.

This article explores the efficiency of photovoltaic (PV) panels, which is crucial in the search for sustainable energy solutions. The study presents a comprehensive analysis of the maximum solar potential achievable through photovoltaic technologies amidst the increasing global energy demands. The research examines solar radiation measurement techniques, the incidence angle of solar rays, and the intricacies of PV panel efficiency. It highlights the potential for improving the performance of solar-based energy systems. Four main sections are covered, beginning with an introduction to the importance of energy storage in sustainable energy production, especially in the context of the European Union’s energy goals and the Green Deal. The following sections discuss the precision needed in the geographical positioning of measurement systems, the impact of light physics, and variable weather conditions on energy capture. The last section presents a novel clock algorithm regulation system designed to enhance the efficiency of the measurement system.
