Biogas purification is possible using the hydrate technique of mixed gas separation technology. The formation–decomposition dynamics of mixed gas hydrates and the advancement of research on the mixed gas separation technology of their hydrate technique are thoroughly reviewed in this study, especially the selective hydrate formation of CH₄containing gas mixtures and their gas separation properties.

Various factors’ regulatory mechanisms and ways of enhancing their effects on the formation of gas mixture hydrate and its gas separation process are described. Finally, the mechanism of the influence of hydrate selective formation on the separation characteristics of gas mixtures is analyzed in depth. Additionally, the challenges and future directions for the large-scale application of hydrate-based mixed gas separation technology were explored. It is noted that the key to achieving an effective purification and separation process of gas mixtures is the directional regulation of the selective hydrate formation process and the synergistic coupling of various reinforcing techniques.

The main findings of previous studies are the creation of zones during carbonation in cement and the mixed minerals of cement and steel during the corrosion process, which could potentially accelerate the corrosion of steel. It is recommended that more experiments be conducted assessing casing, cement and formation as a system in understanding the chemical reaction with CO₂ for long-term storage to predict the reaction rates of cement and steel with CO₂.

The two solutions were compared considering fuel consumption, system footprint, simplicity of implementation, the ratio between liquefied CO₂ and removed CO₂, and thermal integration, which are crucial parameters for integrating a CCS system on board ships. Simulation results showed that the eSMR system offers significant advantages in terms of footprint, design simplicity and thermal integration. However, the tSMR system exhibits greater efficiency in liquefied CO₂ storage and fuel consumption reduction for engines running on HFO with a specific fuel oil consumption (SFOC) of approximately 180 g/kWh. Additionally, it has a smaller footprint at low CO₂ removal rates. Consequently, the optimal solution depends on several factors, including the type of vessel (short- or long-range routes), engine characteristics and specific fuel consumption, the type of fuel used and the CO₂ reduction target.

{"title":"Sustainable Carbon Capture and Storage (CCS) Investments in Oil and Gas: Real Options Analysis Under Energy Transition and Government Incentives","authors":"Dzikri Firmansyah Hakam,&nbsp;Risa Saraswani","doi":"10.1002/ghg.2389","DOIUrl":"https://doi.org/10.1002/ghg.2389","url":null,"abstract":"<div>\u0000 \u0000 <p>Achieving Indonesia's net zero emission (NZE) target by 2060 requires a comprehensive strategy encompassing renewable energy expansion, energy efficiency improvements, electrification of transportation, and the adoption of low-carbon technologies. Beyond these measures, carbon capture and storage (CCS) plays a critical role in addressing emissions from hard-to-abate sectors, such as oil and gas. However, CCS implementation in Indonesia is still in its early stages and faces significant challenges due to uncertainties in policies and carbon pricing. This article evaluates the financial feasibility of CCS project in oil and gas sector in Indonesia. In addition to employing the discounted cash flow (DCF) method, the study utilizes real options valuation (ROV) to better account four uncertainties in resource prices. A binomial tree approach is adopted within the ROV framework. Four scenarios are developed to simulate varying resource prices and incentive schemes: base scenario, zero-assistance scenario, incentive-dependent scenario, and optimal scenario. Using the DCF method, all scenarios yield positive net present values (NPVs). However, when evaluated through the real options approach, only the incentive-dependent and optimal scenarios are deemed viable for immediate investment. Government incentives are shown to significantly reduce the financial burden and mitigate risks, enhancing the viability of CCS projects. Specifically, investment credit plays a pivotal role in lowering the critical carbon price. Without investment credit, the critical carbon price is $80/tCO₂e under low oil price conditions and $60/tCO₂e under high oil price conditions. With sufficient investment credit, the required carbon price drops to as low as $2/tCO₂e. The findings provide practical insights for investors by identifying optimal conditions for CCS project investment under market volatility. For policymakers, the results highlight the need to design stronger fiscal incentives and maintain a predictable carbon price floor to accelerate CCS deployment. Strengthening coordination between the government and oil and gas industry is crucial to ensure project bankability and long-term emission reduction outcomes. In conclusion, a combination of enhanced government incentives and a robust carbon price floor is essential to drive CCS implementation effectively and ensure its contribution to achieving Indonesia's NZE target. 2025 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 2","pages":"196-211"},"PeriodicalIF":2.8,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148082557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sheng","doi":"10.1111/ghg.70001","DOIUrl":"https://doi.org/10.1111/ghg.70001","url":null,"abstract":"<div>\u0000 \u0000 <p>To consume fossil energy and to mitigate global warming, carbon dioxide (CO₂) released from burning fossil energy needs to be captured and stored, because it is believed that released carbon will lead to global temperature rise. Most of the CO₂ captured is stored in geological formations like saline aquifers and oil or gas reservoirs. This article addresses the challenges in these areas. When an aquifer has a closed boundary, the storage capacity which is the compressibility-limited incremental storage is about 1% of the pore volume or at most a few percent because of pressure buildup. Because of this limit, many authors argue that actual aquifer boundaries are semi-closed or open so that the aquifer size is very large or infinite. Such a large aquifer faces the challenges of reservoir characterization, and monitoring, reporting, and verification (MRV), because the large aquifer needs to be characterized, tested, and monitored, and the semi-closed boundaries also need to be tested for CO₂ leakage. To relieve the pressure buildup, production wells are used to simulate the process of CO₂ displacing water. Then another challenge emerges from the displacement process: separation of CO₂ and water, treatment of a large volume of produced water, and reinjection of CO₂. Water disposal can be even more problematic than CO₂ emission. Although oil and gas reservoirs are well characterized, their storage capacity is limited. The wells used in oil and gas reservoirs are Class II which does not satisfy the specifications of Class VI used for permanent CO₂ storage. CO₂ may leak through cement and interfaces of cement with reservoirs and casings, and so forth. The leakage was widely observed in existing abandoned wells and the leak rates varied significantly depending on the well conditions. Although CO₂ helps to produce oil and can be stored in a CO₂-enhanced oil recovery (EOR) process, CO₂ emitted from capturing CO₂ and burning the extra oil is not lower than the amount stored. Because of these challenges and economic hurdles, the executed CO₂ storage projects are far fewer than what was planned and needed to achieve the net-zero target, being about 6%–30%. This article suggests that more fundamental research is needed to study the techno-economic feasibility to safely store CO₂ in geological formations and to estimate the economic burden from CO₂ storage.</p>\u0000 </div>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"16 2","pages":"226-237"},"PeriodicalIF":2.8,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148062281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
