“…Although there are different CCS schemes, reducing the cost of carbon dioxide capture is the most important issue for the CCS process to gain acceptance from the energy industry point of view. There are many methods for CO 2 separation such as absorption, − adsorption, − cryogenic separation, − and membrane technology. − The captured CO 2 is used in various industrial and commercial processes, ,− e.g., urea, liquid fuel, and chemical production. The main focus for CO 2 capturing is on point source streams from energy and emission intensive industries because these sources produce high CO 2 emissions as byproduct.…”

Great efforts are being made to reduce anthropogenic carbon dioxide (CO 2 ) emissions to the atmosphere to mitigate climate change. Different CO 2 capturing techniques are available; however, they have many drawbacks. Through this study, a new method to physically separate CO 2 from its mixture with nitrogen (N 2 ) and hydrogen (H 2 ) gases at supercritical conditions is investigated. This new separation method was tested experimentally at 38 °C and 200 bar. Through a twostage separation, a high-purity CO 2 stream of 99% concentration and pure H 2 and N 2 streams of 96.6 and 91% concentration were obtained, respectively. By using the Aspen Hysys software, the economics of the integration of this new method in an ammonia and urea production plant was compared with that of a traditional plant having CO 2 absorption units in place. The captured CO 2 is utilized in the urea production plant, and the separated pure N 2 /H 2 stream is utilized in the ammonia production plant. A reduction in the capital and operating costs was achieved, with a total savings of $3.32 × 10 8 , which corresponds to 44.6% of the total cost compared to conventional amine-based capture. Our new supercritical phase separation method is economically feasible and could be useful in many energy-related industries.

Since the industrial revolution, global anthropogenic CO2 emissions have surged dramatically to unsustainable levels, resulting in severe issues, such as global warming, extreme weather events, and species extinction. In response to this critical situation, extensive efforts have been undertaken across academia, industry, and policymaking sectors to deploy carbon capture, utilization, and storage (CCUS) technologies. Here, we present the annual summary of global CCUS for the year 2023. We begin by discussing the trends of anthropogenic CO2 emissions and atmospheric CO2 concentrations, and then offer an up‐to‐date summary of progress in academia, industry, and policy, respectively. In academia, we analyze the number and categories of publications and highlight some key breakthroughs. In the industry sector, we meticulously collect and present information on operational commercial carbon‐capture and storage facilities. Furthermore, we elucidate significant policy announcements and reforms across diverse regions. This concise and comprehensive annual report aims to inspire ongoing efforts and collaboration among academia, industry, and policymakers toward advancing carbon neutrality.
