Reduction potential of the energy penalty for CO capture in CCS

《能源前沿（英文）》 2023年第17卷第3期页码 390-399 doi: 10.1007/s11708-023-0864-x

摘要： CO₂ capture and storage (CCS) has been acknowledged as an essential part of a portfolio of technologies that are required to achieve cost-effective long-term CO₂ mitigation. However, the development progress of CCS technologies is far behind the targets set by roadmaps, and engineering practices do not lead to commercial deployment. One of the crucial reasons for this delay lies in the unaffordable penalty caused by CO₂ capture, even though the technology has been commonly recognized as achievable. From the aspects of separation and capture technology innovation, the potential and promising direction for solving this problem were analyzed, and correspondingly, the possible path for deployment of CCS in China was discussed. Under the carbon neutral target recently proposed by the Chinese government, the role of CCS and the key milestones for deployment were indicated.

A systemic review of hydrogen supply chain in energy transition

《能源前沿（英文）》 2023年第17卷第1期页码 102-122 doi: 10.1007/s11708-023-0861-0

摘要： Targeting the net-zero emission (NZE) by 2050, the hydrogen industry is drastically developing in recent years. However, the technologies of hydrogen upstream production, midstream transportation and storage, and downstream utilization are facing obstacles. In this paper, the development of hydrogen industry from the production, transportation and storage, and sustainable economic development perspectives were reviewed. The current challenges and future outlooks were summarized consequently. In the upstream, blue hydrogen is dominating the current hydrogen supply, and an implementation of carbon capture and sequestration (CCS) can raise its cost by 30%. To achieve an economic feasibility, green hydrogen needs to reduce its cost by 75% to approximately 2 /kg at the large scale. The research progress in the midterm sector is still in a preliminary stage, where experimental and theoretical investigations need to be conducted in addressing the impact of embrittlement, contamination, and flammability so that they could provide a solid support for material selection and large-scale feasibility studies. In the downstream utilization, blue hydrogen will be used in producing value-added chemicals in the short-term. Over the long-term, green hydrogen will dominate the market owing to its high energy intensity and zero carbon intensity which provides a promising option for energy storage. Technologies in the hydrogen industry require a comprehensive understanding of their economic and environmental benefits over the whole life cycle in supporting operators and policymakers.

An adaptive policy-based framework for China’s Carbon Capture and Storage development

Xiaoliang YANG, Wolfgang HEIDUG, Douglas COOKE

《工程管理前沿（英文）》 2019年第6卷第1期页码 78-86 doi: 10.1007/s42524-019-0003-x

摘要：

China’s political leadership has taken an increasingly public and proactive stance on climate change since 2014. This stance includes making a commitment that Chinese carbon dioxide (CO₂) emissions will peak around 2030 and enacting measures through the 13th Five-Year Plan to support energy efficiency, clean energy technology, and carbon management. Chinese policymakers consider carbon capture and storage (CCS) a critical bridging technology to help accelerate the decarbonization of its economy. This paper reviews and analyzes Chinese CCS support policies from the perspective of an adaptive policymaking framework, recognizing uncertainty as an inherent element of the policymaking process and drawing general lessons for responding to changing circumstances. Notably, the political support for CCS in China remains fragmented with uncoordinated government leadership, undecided industry players, and even with opposing voices from some leading scientists. There is scope for expanding the framework to provide more granularity, in particular relating to the development of a CCS infrastructure and the development of storage-focused CO2-EOR. Overall, given the role CCS can play to decarbonize China’s power and other industrial sectors, a commitment to CCS from top policymakers and major stakeholders is needed.

基于实时CT扫描技术的CO₂和N₂交替注入条件下煤吸附膨胀和解吸收缩规律研究 Article

张广磊, P.G. Ranjith, Herbert E. Huppert

《工程（英文）》 2022年第18卷第11期页码 88-95 doi: 10.1016/j.eng.2022.03.010

摘要：

深部煤层是分布最广泛的适宜二氧化碳（CO₂）地质封存的地层之一，且通常位于大型CO₂排放源附近。将CO₂注入到煤层中具有巨大的CO₂封存潜力，同时可以提高煤层气的采收率（CO₂-ECBM）。近年来，多个国家在煤层中已经开展了CO₂-ECBM 的先导试验，并取得了良好的可行性验证效果。然而，目前CO₂-ECBM先导实验仍存在技术问题需要解决，即CO₂的注入会引起煤层渗透率降低进而影响长期注入能力。本文采用原位同步辐射X射线显微CT扫描技术，首次在原位条件下直接证明了注入氮气（N₂）可以置换解吸CO₂并减小因CO₂吸附引起的煤基质膨胀，进而重新打开因为CO₂吸附而闭合的裂隙促使渗透率回升。研究结果表明，煤层中注入经过简单处理的烟道气（主要成分为N₂和CO₂），是技术上可行的CO₂-ECBM 替代方案。首先，发电厂产生的烟道气可以在去除颗粒物后直接注入，从而避免了较高的CO₂分离成本。其次，N₂的存在可以使煤层保持较高的渗透率，实现长期CO₂注入封存和煤层气增产。总之，深部煤层中注入烟道气一方面可以实现CO₂大量封存，另一方面可以强化煤层气开采，为煤矿实现净零排放提供了一条有效途径。

Carbon capture for decarbonisation of energy-intensive industries: a comparative review of techno-economic feasibility of solid looping cycles

《化学科学与工程前沿（英文）》 2022年第16卷第9期页码 1291-1317 doi: 10.1007/s11705-022-2151-5

摘要： Carbon capture and storage will play a crucial role in industrial decarbonisation. However, the current literature presents a large variability in the techno-economic feasibility of CO₂ capture technologies. Consequently, reliable pathways for carbon capture deployment in energy-intensive industries are still missing. This work provides a comprehensive review of the state-of-the-art CO₂ capture technologies for decarbonisation of the iron and steel, cement, petroleum refining, and pulp and paper industries. Amine scrubbing was shown to be the least feasible option, resulting in the average avoided CO₂ cost of between 62.7

for the iron and steel industry. Its average equivalent energy requirement varied between 2.7 (iron and steel) and 5.1

(cement). Its average equivalent energy requirement varied between 2.0 (iron and steel) and 3.7

《化学科学与工程前沿（英文）》 2020年第14卷第3期页码 436-452 doi: 10.1007/s11705-019-1870-8

摘要： This paper compares the techno-economic performances of three technologies for CO capture from a lignite-based IGCC power plant located in the Czech Republic: (1) Physical absorption with a Rectisol-based process; (2) Polymeric CO -selective membrane-based capture; (3) Low-temperature capture. The evaluations show that the IGCC plant with CO capture leads to costs of electricity between 91 and 120 €·MWh , depending on the capture technology employed, compared to 65 €·MWh for the power plant without capture. This results in CO avoidance costs ranging from 42 to 84 €· , mainly linked to the losses in net power output. From both energy and cost points of view, the low-temperature and Rectisol based CO capture processes are the most efficient capture technologies. Furthermore, partial CO capture appears as a good mean to ensure early implementation due to the limited increase in CO avoidance cost when considering partial capture. To go beyond the two specific CO -selective membranes considered, a cost/membrane property map for CO -selective membranes was developed. This map emphasise the need to develop high performance membrane to compete with solvent technology. Finally, the cost of the whole CCS chain was estimated at 54 €· once pipeline transport and storage are taken into consideration.

碳捕集和封存技术研究开发及未来清洁能源行业部署—— 澳大利亚在过去20年中的经验教训

Cook Peter J.

《工程（英文）》 2017年第3卷第4期页码 477-484 doi: 10.1016/J.ENG.2017.04.014

摘要：

碳捕集和封存（CCS）技术作为一种碳减排手段，虽未得到全方位认可，但其重要性已得到人们的广泛认可。但是，若要将全球温度上升幅度控制在低于2℃，则此技术的推广应用速度并不能满足相关的需求。虽然大规模推广CCS 技术所面临的困难尚无法全部克服，但通过不断的研究、交流和规划，目前CCS 技术已得到了极大丰富。

二氧化碳捕集与封存——历史与未来之路 Review

马劲风, 李琳, 王浩璠, 杜艺, 马俊杰, 张小莉, 王震亮

《工程（英文）》 2022年第14卷第7期页码 33-43 doi: 10.1016/j.eng.2021.11.024

摘要：

二氧化碳捕集与封存（CCS）的大规模部署在全球实现净零排放的道路中显得越发紧迫，但CCS的全球部署显著落后于预期。回顾和学习先进国家CCS的成功实例与历史，有助于包括中国在内的国家采取科学的方法来推动与部署CCS项目。在CCS关键技术研发与示范中，本文认为先进国家CCS科技基础研究设施的建立是其CCS技术源头创新、成本降低、风险降低、商业化推广及人才培养的源泉。除了激励政策外，CCS的良性发展，需要从科技基础研究设施过渡到规模化商业化设施，不然难以跨越从小规模示范到百万吨级CCS中心（hub）与千万吨级CCS hub实施的技术障碍。CO₂地质封存是CCS项目的最终目标与解决捕集CO₂归宿的驱动力。

《工程（英文）》 2017年第3卷第4期页码 485-493 doi: 10.1016/J.ENG.2017.04.004

摘要：

气体膜分离法是从气流中分离二氧化碳（CO₂）的最有前途的技术之一。例如，采用该技术对燃烧过程中的烟气进行处理，以达到CO₂ 捕集和封存的目的。聚环氧乙烷嵌段共聚物能够很好地应用于膜分离技术，如Pebax® 或PolyActive™。本文采用PolyActive™ 作为复合薄膜的选择层。在环境温度下，当CO₂/N₂ 选择性超过55 时，这种薄膜的CO₂渗透率高达4 m³(STP)·m⁻²·h⁻¹·bar⁻¹（注：1bar=10⁵ Pa）。这种薄膜可以按照中试规模进行生产放大，而且可以设计成不同的平面膜组件。采用单一气体渗透数据作为唯一的实验输入而开发出的仿真工具可以准确预测这种膜组件的性能。在不同的中试研究中，我们利用烟气和沼气作为原料气流，反复检测这些膜和膜组件的性能。PolyActive™ 在检测中显示出了稳定的分离性能，表明PolyActive™ 非常适用于作为膜材料进行工业规模气体处理。
