Summary: Direct air carbon capture and storage (DACCS) is a method of capturing CO2 directly from the air and storing it for a long time. Despite being in the early stages of technical development, DACCS faces challenges such as high cost and energy requirements. This paper provides an overview and classification of DACCS systems, harmonizes the technical and economic performance of direct air capture technologies, lists technical and infrastructure-based obstacles to scaling DACCS systems, and provides a roadmap and priority initiatives for research, development, demonstration, and deployment of DACCS.

Summary: Directly capturing CO2 from the air at ambient conditions is challenging due to the competition of water adsorption and low CO2 pressure. In this study, we developed amine-functionalized quasi-metal-organic frameworks (X-UIO-EDA) with high CO2 capture capacity, and discovered that water-assistance enhances CO2 capture under 400 ppm CO2 and humidity. The results showed that 2-UIO-EDA had a 10-fold higher CO2 capture capacity under humid air conditions compared to dry air conditions, and quasi-UIO-66 had more amine modification sites for higher CO2 capture.

Summary: Two CO2 chemical absorption systems using AMP and MEA aqueous solutions were compared in terms of absorption performance and electrical properties. The study found that the absorption capacity in the AMP system increases linearly with C-ini, while the absorption rate in the MEA system is affected by concentration and primary reaction changes. The differences in performance can be attributed to the molecular structures and sizes of the two systems.

Summary: A new model for the adsorption kinetics of CO2 on amine functionalized metal-organic frameworks is proposed, providing a microscopic interpretation of the adsorption behavior. The model accounts for both singly adsorbed CO2 and adsorption into chains, accurately describing complex kinetic phenomena observed in low partial pressure CO2 breakthrough curves.

Summary: This study investigates the absorption of diluted CO2 in carbonated NaOH solutions as a replacement for the conventional ammonia-soda process. By refitting the parameters, the average error was reduced and the mass transfer coefficient was evaluated for process design. The effects of NaOH and Na2CO3 concentrations and temperature on the mass transfer coefficient were studied.

Summary: We developed a thermochemical model to evaluate the CO2 regeneration energies in aqueous solutions of MEA, DEA, AMP, and IPAE. The regeneration heat includes reaction heat, sensible heat, and vaporization heat. We calculated the reaction heat using our model and determined the concentrations of all chemical species in the CO2 absorption and release states. The contribution of protonation reaction is significant in sterically hindered amines AMP and IPAE, while both protonation and carbamate hydrolysis play important roles in MEA and DEA. Sensible heat dominates the regeneration heat compared to reaction and vaporization heats.

Summary: The study evaluates the use of TEPA-modified hierarchical silica particles for CO2 capture under DAC conditions. The results show that the TEPA-impregnated HS exhibits high CO2 uptake, shorter adsorption time, and excellent amine efficiency. It also demonstrates good performance under humid conditions and thermal stability during multiple adsorption-desorption cycles. The pelletized form of HS-TEPA-70 shows promise for CO2 capture using temperature swing adsorption.

Summary: Carbon dioxide (CO2) capture and storage (CCS) is crucial for enabling the use of fossil fuels while addressing environmental concerns. Among the CO2 capture technologies, postcombustion CO2 capture using solid adsorbents has gained attention due to its noncorrosive nature and low energy demand. However, the design of efficient and stable amine-containing adsorbents for postcombustion CO2 capture is a complex challenge. This article focuses on the development of energy-efficient adsorbents for CO2 capture via temperature swing adsorption (TSA). The key challenges include improving CO2 adsorption capacity, suppressing coadsorption of water, and enhancing the stability of the adsorbents. By combining macroporous silica hosts, alkyl-epoxide-functionalized poly(ethylenimine) (PEI), and phosphate-based oxidative stabilizers, the authors have synthesized adsorbents that exhibit low energy demands and high thermochemical stability. The discussions provide important insights for the practical design of adsorbents for CO2 capture.

Summary: The study found a significant positive correlation between CRP enrollment and downstream water quality, but correlation does not imply causation. More research is needed to expand spatial and/or temporal scales and consider additional water quality variables to enhance understanding of the coupled natural-and-human system.

Summary: This study investigates the degradation kinetics of polyamide thin films when exposed to PAA and HOCl solutions, revealing a two-stage behavior with PAA involving physical sorption and oxidation processes, while HOCl leads to rapid decay. PAA demonstrates higher compatibility with polyamide compared to chlorine, supporting its potential as a halogen-free membrane cleaning/disinfecting agent.

Summary: This study evaluates the performance of a novel AOP ultraviolet/peracetic acid (UV/PAA) and conventional UV/hydrogen peroxide (UV/H2O2) through targeted PPCP analysis, Daphnia survivability and life history, and high-resolution mass spectrometry-based targeted lipidomics analysis. Both AOP treatments significantly decreased the concentrations of pharmaceuticals and personal care products (PPCPs) in wastewater. However, the UV/PAA AOP treatment showed a less significant decrease in toxicity compared to other treatments, resulting in slower growth, changes in lipid composition, and lower population increase in Daphnia.

Summary: The study demonstrates that Peracetic acid (PAA) induces less changes in the performance and material characteristics of NF90 membranes compared to traditional disinfectant free chlorine (NaOCl), making it a viable candidate for wastewater reuse. PAA exposure leads to minimal impact on membrane water flux and rejection of salt and organic compounds, even at low levels, and has unexpected protective effects against radicals formed by Fe(ii) and H2O2 in commercial PAA formulations.
