Enhancement Strategies of Calcium Looping Technology and CaO‐Based Sorbents for Carbon Capture

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 28, 2025

Abstract As global warming intensifies and energy resources deplete, carbon capture sustainable conversion technologies gain increasing importance. Among these, calcium looping (CaL) technology has demonstrated promising cost‐effectiveness ease of integration with other systems. However, severe sintering CaO‐based sorbents occurs during cyclic carbonation calcination, resulting in a significant decrease CO 2 capacity stability. This paper reviews enhancement strategies aggregate for synthetic over the past 10 years, compiling tabular dataset 1042 reported materials, to compare effects synthesis methods operation conditions on decay rate capacity. Sol‐gel, combustion, template are recommended producing high porosity sorbents. The precursors organic acids used synthesis, addition dopants, also play important roles affecting sorbent performance. examines relationship between material conditions, performance determine feasibility applying machine learning materials development. discusses several possible artificial intelligence potential designing innovative suitable long‐term industrial applications, XGBoost model providing predictive capacity, particularly when working relatively small, tabular, datasets.

Progress in Recyclable Chemicals for Sustainable Ex-situ CO2 Mineralisation

Green Energy and Resources, Journal Year: 2024, Volume and Issue: 2(3), P. 100087 - 100087

Published: Aug. 23, 2024

The 21st century grapples with rising atmospheric CO2 and anthropogenic solid waste. Ex-situ mineralisation, converting into stable carbonates via reacting waste, shows great promise. However, concerns over the extensive consumption of chemicals urge sustainable recyclable alternatives. This paper critically reviews for mineralisation various industrial wastes, systematically examines their efficacy reaction mechanisms. study offers a comprehensive comparison these outlines clear future research directions. main findings are briefed below: first, we emphasize pivotal role trapping recycling NH3 gas achieving effective efficient using ammonium salts. Second, scaling up amines-based could be feasible by replacing conventional strippers units. transition is contingent upon resolving technical challenges such as amines' low leaching capacity limited applicability to feedstocks that contain water-soluble Ca/Mg-bearing species. Third, leveraging unique zwitterionic structures, amino acids may cater diverse needs achieve satisfactory efficiency good recyclability at temperatures. Fourth, novel HCl regeneration technology known 'oxy-pyrohydrolysis,' can simultaneous in single step. both acids-based oxy-pyrohydrolysis nascent technologies requiring further ascertain advance development. Fifth, despite employing chemicals, operational costs remain significant when high temperatures used. Thus, energy optimization strategies should explored, exploring low-energy integrating waste harvesting review aims delineate potential avenues cost-effective facilitated thereby alleviating post-processing environmental associated chemical residues.
