Climate issues, especially linked to the greenhouse effect and global warming, are receiving increasing attention. The most direct cause is the overproduction of anthropogenic carbon dioxide. Carbon capture and storage (CCS) is one of the main strategies for mitigating and controlling CO 2 emissions from large emission sources, as well as achieving large-scale CO 2 emission reductions. [1] In October 2018, the Intergovernmental Panel on Climate Change (IPCC) released the 1.5 C Special Report in Incheon, which found that global CO 2 emissions would need to fall by %45% from 2010 levels by 2030, and that the world should aim to be carbon neutral by %2050 by removing CO 2 from the air to stabilize remaining emissions. [2] In June 2019, China released The Third Information Bulletin and The Second Biennial Update, which highlighted CO 2 as the main greenhouse gas emitted by China. However, compared with 2005, China's energy-related CO 2 emissions per unit of GDP decreased by 40.7% in 2016. Nevertheless, the rapid and widespread reduction in carbon emissions is required from all sectors to limit the global temperature rise to 1.5 C or even 2 C. [3] The desire for a shared future for mankind has prompted China to establish increasingly severe emission-control scenarios that call for accelerated development of practical carbon capture technology. [4] However, a lack of generalized methods and reasonable benchmarking analysis of the energy efficiency of typical carbon capture technologies may lead to low reliability, poor generalization, and even contrasting research conclusions regarding their energy efficiency and energy consumption. Thus, an adequate benchmarking analysis framework is urgently required for carbon capture technology. CCS is widely regarded as a new solution to the common challenges currently faced by human society. [5] However, in recent years, CCS research has been inhibited by the "old" problem of excess specific-heat consumption. Thus, it is difficult to promote technological development with sustainable cost control. Moreover, according to the first law of thermodynamics, current carbon capture technology typically requires heat consumption of 3-4 GJ to capture 1 ton of CO 2. [6] Furthermore, its theoretical exergy efficiency is generally below 20% and it exhibits low technology maturity, despite substantial potential for energy conservation and consumption reduction. [7] For post-combustion CO 2 capture, the feasibility of several technologies (such as absorption, adsorption, membrane, and cryogenic methods) has previously been demonstrated. [8] Adsorption is considered to be a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
