Summary: Over the past 30 years, the increase in energy demand due to technological advancements following the industrial revolution has led to a rise in CO2 and greenhouse gas concentrations globally. Reducing emissions of these gases has become a critical challenge for industries, and Carbon Dioxide Capture and Utilization (CCU) technology is seen as a potential solution. This article explores the possibility of using the new Chilled Ammonia Process (CAP) technology as an alternative method for CO2 recovery from ammonia plant flue gases, highlighting its advantages of capturing pollutants and converting them into valuable chemical fertilizers, while significantly reducing costs and energy consumption.

Summary: This study investigates the potential of ammonia production from local coal and biomass resources with CO2 capture for negative emissions. Two innovative configurations are compared with a benchmark, and the results show lower and higher costs for the E-gas and MHI concepts, respectively. Benchmarking against alternative ammonia supply pathways indicates that the energy security offered by the E-gas configuration may be economically attractive to importers with rising CO2 taxes.

Summary: Climate change and global warming, caused by anthropogenic CO2 emissions, is recognized as the largest threat to global ecosystems. Utilizing biomass ash from combustion as a source for activated carbon production not only valorizes waste into value-added products, but also provides an abundant and cost-effective material for post-combustion carbon capture. This research focuses on the preparation and characterization of biomass ash-derived activated carbon with optimized yield and CO2 uptake, achieving nearly double the adsorption capacity compared to virgin biomass ash-derived carbon.

Summary: Expanding populations and growing economies lead to higher energy demands, which require a diverse energy mix and deployment of carbon capture and removal technologies to reduce carbon emissions. However, the lack of materials-related information and the inconsistency in measurement parameters and data presentation pose challenges to the scale-up of these technologies, especially in the case of solid adsorption-based carbon capture. This review examines the characterization of solid sorbents for carbon capture, focusing on performance parameters and experimental conditions, and emphasizes the importance of experimental data.

Summary: The applicability of 3D-printed activated carbons for CO2 capture in post-combustion streams and the influence of activation conditions on CO2 uptake and CO2/N2 selectivity were studied. The results showed that higher burnoff during activation increased the adsorption capacity of CO2 and N2, while lower burnoff led to higher selectivity of CO2 over N2. The study also proposed modeling approaches for describing single and multicomponent adsorption equilibrium, and demonstrated the working capacity and stability of the carbon.

Summary: Assessing the role of carbon capture in energy systems dominated by non-dispatchable renewable energy sources requires a reliable and accurate model. Therefore, a mixed-integer linear model of post-combustion carbon capture was developed based on rigorous thermodynamic modeling in Aspen Plus. The model accurately determines the size and operation of the capture process and provides cost and energy requirements based on CO2 concentration and flow rate of treated flue gas. Validation against actual plant data showed excellent accuracy, and applying the model to a case study demonstrated its potential for optimizing renewables deployment and carbon capture design in gas turbine systems.

Summary: The chemical industry, responsible for 5% of global CO2 emissions, plays a crucial role in achieving net-zero targets. However, decarbonizing this industry faces challenges due to carbon-rich raw materials, high-temperature heat requirements, and complex value chains. Multiple technology routes for producing net-zero chemicals exist but their viability depends on local energy and resource availability. This review compares net-zero routes by quantifying their energy, land, and water requirements and discusses the technical and environmental feasibility of a net-zero chemical industry, suggesting a need for integrated solutions that combine net-zero routes with circular approaches and demand-side measures, potentially impacting global chemicals trade.
