“…CO 2 separation is usually done using a high-temperature solid sorbent such as calcium oxide (CaO) which can be regenerated by temperature swing or pressure swing to produce pure CO 2 stream [73]. With the sorbent capture cost going as low as USD 9-11 per tonne of CO 2 captured, a pure hydrogen stream of up to 99% can be attained [74,75]. This technology is already being demonstrated at the pilot stage.…”

Our ever-increasing interest in economic growth is leading the way to the decline of natural resources, the detriment of air quality, and is fostering climate change. One potential solution to reduce carbon dioxide emissions from industrial emitters is the exploitation of carbon capture and storage (CCS). Among the various CO2 separation technologies, cryogenic carbon capture (CCC) could emerge by offering high CO2 recovery rates and purity levels. This review covers the different CCC methods that are being developed, their benefits, and the current challenges deterring their commercialisation. It also offers an appraisal for selected feasible small- and large-scale CCC applications, including blue hydrogen production and direct air capture. This work considers their technological readiness for CCC deployment and acknowledges competing technologies and ends by providing some insights into future directions related to the R&D for CCC systems.

“…5(a), employing CaO as sorbent in the reformer, the amounts of H 2 decreased from 78 vol% at 500 C to 56 vol% at 800 C. A sharp decrease aer 650 C was noticed on account of optimal range of sorption temperature (500 to 650 C) for CaO. 10,17 CO 2 was captured by CaO from 500 to 650 C via carbonation reaction (E10) forming CaCO 3 . Beyond 650 C, decarbonation began forming CO 2 and sorbent.…”

“…In addition to its low operating temperature, magnesium oxide is abundant, low cost and has a high theoretical maximum CO2 uptake of 110 wt% [51]. Recent work published on various aspects of MgO used in CCUS include a comprehensive summary of performance enhancements and optimization of MgO sorbents [51], a review of the kinetics of carbon dioxide capture of solid sorbents including MgO [49] and a critical analysis of the mechanisms of CO2 interaction with the MgO surface [31]. In this review, we provide an updated review of papers that have brought new insight into the fundamental understanding of CO2 capture by…”

Carbon dioxide capture and mitigation forms a key part of the technological response to combat climate change and reduce CO2 emissions. Solid materials capable of reversibly absorbing CO2 have been the focus of intense research for the past two decades, promising stability and low energy costs to implement and operate compared to the more widely used liquid amines. In this Review, we explore the fundamental aspects underpinning solid CO2 sorbents based on alkali and alkaline earth metal oxides operating at mid- to high temperature: how their structure, chemical composition and morphology impact their performance and long-term use. Various optimization strategies are outlined to improve upon the most promising materials, and we combine recent advances across disparate scientific disciplines including materials discovery, synthesis, and in situ characterization to present a coherent understanding of the mechanisms of CO2 absorption both at surfaces and within solid materials.
