“… This process, termed calcium (or carbonate) looping (CaL), formed the basis for research on CO 2 capture by metal oxides at medium to high temperatures (>200 °C) to the present day. The higher operating temperatures of metal oxides compared to liquid amines gives the promise of a lower energy penalty incurred if implemented into power plants or other high-temperature processes, driving interest in their further development. , There has been a great deal of research aimed at understanding various aspects of the CO 2 absorption reaction at elevated temperature, including the materials that are of potential interest, and various modifications and optimizations that can be performed to achieve benchmarks set by governments and industry.…”

Carbon dioxide capture and mitigation form 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, with 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 medium 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.

“…Alkaline earth metal oxide-based sorbents that reversibly ab-and desorb CO 2 have attracted attention in the framework of CCS due to favourable cost estimates for CO 2 capture compared to amine scrubbing. [1][2][3] Magnesium oxide-based sorbents that capture CO 2 reversibly through the reaction MgO + CO 2 4 MgCO 3 at intermediate temperatures (300-500 C) have shown great potential for CCS owing to its high theoretical gravimetric uptake (1.09 gCO 2 gMgO À1 ) and low energy requirement for sorbent regeneration (2.68 kJ g À1 CO 2 ) when compared to other metal oxide sorbents (e.g. 4.04 kJ g À1 CO 2 for CaO).…”

“…This process, termed calcium (or carbonate) looping (CaL), formed the basis for research on CO2 capture by metal oxides at mid-to high temperatures (> 200 °C) to the present day. The higher operating temperatures of metal oxides compared to liquid amines gives the promise of a lower energy penalty incurred if implemented into power plants, driving interest in their further development [29], [30]. There has been a great deal of research aimed at understanding various aspects of the CO2 absorption reaction at elevated temperature, including the materials that are of potential interest, and various modifications and optimizations that can be performed to achieve benchmarks set by governments and industry.…”

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.
