An important technology now being assessed to support decarbonization goals is CO2 capture, utilization, and storage (CCUS). CO2 capture technologies can reduce emissions from industrial processes and power generation by up to 90%. In this study, we review the main components of business models and emphasize the key area to be emphasized when developing a CCUS business model. A business model for CCUS application should be distinguished at the value proposition stage for the three archetypes (resource recovery, green growth, low carbon grid). The results of the study indicate that there is a possible overlap between the value propositions of CCUS projects. A successful business model needs to highlight the value proposition in terms of value creation and delivery in CCU solutions in specific industries. This would ensure consistent comparison across the global studies. Copyright 2025, carbon capture, utilization, and Storage conference (CCUS).

carbon capture and utilization is an emerging technology used to mitigate CO2 emissions. Incorporating captured CO2 as a raw material in the chemical industry provides a sustainable CO2 reduction approach rather than mere disposal. Existing literature showcases successful experiments demonstrating CO2's feasibility as a raw material. However, not all carbon capture and utilization products have the capacity to efficiently utilize substantial amounts of CO2 or be economically viable. Therefore, this study concentrates on investigating carbon capture and utilization processes, warranting further exploration and comparison with conventional process based on techno-economic feasibility, sustainability, and market potential by proposing novel methodology. Sustainable feasibility index was developed to rank promising carbon capture and utilization processes based on technoeconomic, environmental, and market size considerations. Eleven high-potential products were investigated. Acetic acid, formic acid, and calcium formate were identified as the top-ranking products for the base cases. Results from carbon to hydrogen mass ratio indicated decreasing the global warming index of CO2 have a larger effect compared to decreasing the global warming index of H2 on overall carbon footprint of the products. Future projections with respect to raw material sources show the changes in CO2 sources when compared to changes in the hydrogen and electricity sources, have the most significant effects on the levelized cost of the product and global warming index. Additionally, this work seeks to ease the decision-making for stakeholders regarding the selection of feasible and sustainable carbon capture and utilization processes with a detailed comparative investigation.

Ammonia production represents a fundamental aspect of the global chemical industry. It is a significant contributor to carbon dioxide (CO2) emissions, and it is necessary that innovative methods be developed to reduce its climate impact. This study assesses the environmental impact of blue ammonia production incorporating carbon capture and utilization (CCU) through a novel Life Cycle Assessment (LCA) approach, based on the latest guidelines from the Together for Sustainability (TfS) initiative. This analysis is centred on three systems: grey ammonia (System A), blue ammonia with in-process carbon capture (System B), and blue ammonia utilizing system expansion via direct air capture (DAC) (System C). The results demonstrate that the production of grey ammonia in Germany generates 3.12 kgCO2eq per kg of ammonia, predominantly due to emissions from steam methane reforming (SMR). The incorporation of in-process CO2 capture in blue ammonia (System B) results in a climate impact of 1.79 kgCO2eq for the functional unit of 1 kg ammonia plus 1.85 kg of succesfully captured CO2. The implementation of system expansion via DAC (System C), as recommended by the TfS guidelines, results in a further reduction of ammonia emissions to 2.64 kgCO2eq, in comparison to System A. This approach also yields a net negative impact of -0.85 kgCO2eq for the captured CO2 co-product, enabling the realization of the shared incentivization objective articulated in the suggested guideline. The regional scenarios convincingly demonstrate that the proposed approach achieves varying levels of success, often leading to more polarized incentivization. The future scenario will significantly enhance the benefits of CCU and the utilization of CO2 as a co-product. However, this will be at the expense of incentivizing the production of blue ammonia. This work advances the methodologies for LCA of multi-functional CCU systems, demonstrating the potential for shared incentives in the transition to a new ammon

Integrating carbon capture and utilization (CCU) technologies into wastewater treatment plants (WWTPs) is essential for mitigating greenhouse gas (GHG) emissions and enhancing environmental sustainability, but further advancements in process monitoring and control are critical to optimizing treatment performance. This study investigates the application of artificial intelligence (AI) modeling to enhance process monitoring and control in a novel integrated CCU biotechnology with a moving bed biofilm reactor (MBBR) sequenced with an algal photobioreactor (aPBR). This system reduces GHG and odour emissions simultaneously. Several machine learning (ML) models, including artificial neural networks (ANNs), support vector machines (SVM), random forest (RF), and least-squares boosting (LSBoost), were tested. The LSBoost was the most suitable for modeling the MBBR + aPBR system, exhibiting the highest accuracy in predicting CO2 (R2 = 0.97) and H2S (R2 = 0.95) emissions from the MBBR. LSBoost also achieved the highest accuracy for predicting CO2 (R2 = 0.85) and H2S (R2 = 0.97) outlet concentrations from the aPBR. These findings underscore the importance of aligning AI algorithms to the characteristics of the treatment technology. The proposed AI models outperformed conventional statistical methods, demonstrating their ability to capture the complex, nonlinear dynamics typical of processes in environmental technologies. This study highlights the potential of AI-driven monitoring and control systems to significantly improve the efficiency of CCU biotechnologies in WWTPs for climate change mitigation and sustainable wastewater management. © 2025

Nesquehonite (MgCO33H2O) is of interest as a carbon sink for mineral carbonation as its formation is kinetically favored at ambient temperatures and pressures and offers the highest CO2 : MgO ratio compared to most other hydrated magnesium carbonates (HMCs). However, the phase tends to convert to more stable HMCs depending on the environment and time leading to long-term instability. Here, we report a successful attempt to stabilize nesquehonite using a phosphate-based pH 7 buffer, while controlling the equilibrium of aqueous carbonate species did not stabilize the phase. Phosphate interacts with nesquehonite to form a Mg-phosphate phase on nesquehonite's surface. We suggest that a protective layer is formed, which prevents further transformation of nesquehonite.

To achieve Austria’s climate targets, a solid data foundation and reliable facts are essential for political and economic decision-makers to implement strategic initiatives. The CaCTUS project addresses existing knowledge gaps regarding the realistic potential of CO2 capture, utilization, and storage (CCUS) in Austria and examines its technical and economic implications for the established climate goals. As part of the project, existing and future carbon sources as well as potential sinks for 2040 and 2050 were identified and quantified in collaboration with stakeholders from industry and government ministries. Based on this, source-to-sink pathways were evaluated from techno-economic and legal perspectives to identify cost-efficient and competitive solutions for Austria’s ‘hard-to-abate’ emissions. Finally, recommendations for the implementation of CCUS technologies, legal frameworks, and potential impacts were summarized in policy briefs for decision-makers. © The Author(s) 2025.

As human societies are dealing with climate change consequences, researchers are investigating different methods to capture and sequester greenhouse gases as much as possible. Mineral carbonation in waste mine tailings is known to be a potentially easy CO2 sequestration method for permanent and high storage capacity. In this paper, accelerated carbonation of two zinc ore tailings from the same mine has been investigated. After measuring the maximum carbon dioxide capture and storage capacity, the tailings are used to produce geopolymers through alkali activation. The influence of CO2 pretreatment on the mechanical and chemical properties of the produced geopolymer blocks is analyzed. Results show that about 27.16% and 35.07% CO2 storage is viable by dry carbonation in saturated and weathered tailing samples, respectively. © ASCE.

Algae plays a key role in carbon capture and utilization (CCU) as it can capture and use the atmospheric CO2 for conversion of value-added products. Concentrated CO2 is common in flue gas and provides opportunities for algae cultivation. The drawbacks are mass transfer limitation, poor CO2 dissolution, and challenges to reach optimal levels for algal growth at given flue gas levels. Bicarbonate is flexible to be used as carbon source and owns the potential to enhance the efficiency of biological carbon fixation by algae. The requirements of algae strains are more stringent. To improve the industrial scale-up of CCU, system optimization is of great importance. More novel algal strains that can grow rapidly under harsh environment and provide valuable bio-products should be developed for large-scale production. Algae-driven CCU is promising for achieving carbon-neutrality.

The conversion of carbon dioxide (COQ) into dimethyl ether (DME) represents a promising alternative in the field of carbon capture and utilization (CCU) processes. In this paper, a novel multi-stage Condensation-Enhanced carbon utilization (multi-CECU) process was modeled and simulated with the objective of contributing to the ongoing efforts in process intensification. The efficacy of six distinct arrangements, including the single-stage configuration, was examined to assess the advantages of a multi-stage synthesis process in terms of DME production, COQ conversion, energetic self-sufficiency and exergy efficiency. More in detail, a thermodynamic and kinetic analysis was first conducted on both Aspen Plus and Matlab to determine the optimal operating conditions and design the reactor. Subsequently, a preliminary assessment was performed to identify the more adequate separation temperature to enhance the production of DME throughout the removal of condensable coproducts after the six configurations were implemented on Aspen Plus. Once assumed the temperature based on a trade-off between productivity and energy expenditures, the five multi-CECU arrangements were benchmarked with the single-stage configuration based on relevant technical performances, energetic self-sufficiency, and exergy efficiency by quantifying the overall and relative improvement associated with the introduction of each individual reaction stage. As a result, the 4-stages configuration revealed the greatest improvement potential, with a CO2 plant conversion of 97.23%, a chemical conversion efficiency to DME of 64.37% and an exergy efficiency of 79.02%. The implementation of heat recovery strategies reduced external heat requirements by nearly 60% and cooling requirements by 40%, highlighting the multi-CECU process as a viable solution for sustainable and reliable energy management.
