“…Carbon capture, utilization, and storage (CCUS) is an essential technique for achieving the goals set forth in the Paris Agreement, particularly the target of limiting global warming to 1.5 °C (Zheng et al, 2022a;Shen et al, 2022;Zhao et al, 2022;Zhu et al, 2022). It plays a crucial role in mitigating greenhouse gas emissions and reducing the concentration of carbon dioxide (CO 2 ) in the atmosphere (Lab, 2022;Hou et al, 2024a).…”

CO2, used as an environmentally friendly fracturing fluid, has encountered a bottleneck in development in recent years. Despite great efforts in research work, limited progress has been made in field applications. In this study, an extensive literature review of research work and field cases was performed to summarize the technical issues and challenges of CO2 fracturing. The key issues of CO2 fracturing were analyzed to reveal the gap between fundamental research and field operations. The effects of CO2 properties on fracture creation and proppant transport were synthetically analyzed to extract new common research orientations, with the aim of improving the efficiency of CO2 injection. The hydraulic parameters of CO2 fracturing were compared with those of water-based fracturing fluids, which revealed a theory-practice gap. By studying the developing trends and successful experiences of conventional fluids, new strategies for CO2 fracturing were proposed. We identified that the major theory-practice gap in CO2 fracturing exists in pump rate and operation scale. Consequently, the friction reducer, effects of flow loss (due to leak-off) and distribution (within fracture networks), and shear viscosity of thickened CO2 are key factors in improving both fracture propagation and proppant transport. By increasing the scale of injected CO2, the CO2 fracturing technique can be enhanced, making it an essential option for carbon capture, utilization, and storage (CCUS) to reduce carbon emissions and mitigate climate change.

“…However, fuels of the future are an emerging area in the transportation sector, with a wide range of fuels being developed for subsequent use by various industries, e.g., the shipping industry is using bio and synthetic liquefied natural gas (LNG), ammonia, methanol, hydrogen, and biofuels [44,[61][62][63]. Future fuels are being evaluated on the basis of their environmental friendliness, and the lifecycle approach considers the entire chain, namely, from the well to final application ("from well to wake") [64][65][66]. Sustainable fuels, such as hydrotreated vegetable oil, and synthetic fuels, such as ammonia or methanol, are also being developed, with a production capacity of 46 million tons by 2025 and a total planned investment of USD 40 to USD 50 billion.…”

Fossil fuels play a powerful role in the global economy and are therefore referred to as strategic raw materials. However, their massive use around the world is associated with concerns about the sufficiency of energy sources for future generations. Currently, fossil fuel resources are heavily depleted, with limited supplies. According to forecasts, the demand for energy will constantly increase, so it is necessary to find a solution that reconciles the ever-increasing demand for energy with the need to protect the environment. The main solution to this problem is to acquire energy from renewable resources, especially in the direction of obtaining alternative substitutes for transportation fuels. One of the main alternative fuels that can replace existing fossil fuels is hydrogen. An efficient way to obtain this compound is through the use of modern photocatalysts. Hence, the purpose of this paper is to review the recent literature on the effective use of catalysts in photocatalytic processes (e.g., glycerol conversion) that enable the synthesis of hydrogen.
