人为温室气体排放是全球变暖的主要原因，而二氧化碳作为主要温室气体之一，对气候变化负有不可推卸的责任。目前，包括碳捕集与封存（CCS）技术在内的各种节能减排技术以及其他清洁低碳能源开发技术呈现出快速发展的趋势，以缓解日益严重的气候变化危机。在传统的二氧化碳地质封存的基础上，提出了一种新的二氧化碳地质利用与封存的地球工程方法，即二氧化碳地质封存与深盐水回收（CO2-EWR）相结合，以解决中国煤化工行业碳排放不断增加与国家能源和水安全之间的困境。与传统的CCS技术相比，CO2- ewr具有两大优势：(1)通过合理设计抽水井，控制储层压力释放和出水量，实现大规模地质封存CO2的安全稳定；(2)深层盐水经处理后可收集处理，用于生活饮用、工业和/或农业利用，缓解水资源短缺和生态环境问题，深层盐水资源通过梯级提取可创造可观的利润空间，可填补目前CCS技术捕集和封存过程中主要存在的成本缺口。中国大陆主要根据不同的含水层系统类型划分为3个潜在的CO2-EWR区，而考虑到所采用的潜在技术的研发成熟度和成本预测，可以发现中国西部地区煤电和煤化工企业有较早的机会。从节能减排和环境友好的角度，分析了CO2-EWR技术的深层咸水蓄水、咸水提取与淡化、盐水资源利用三个子模块。通过详细的分析，得出CO2-EWR技术绝对可以被认为是改善环境和绿色发展的清洁技术，最后指出了CO2-EWR技术的发展方向和未来前景。
Anthropogenic greenhouse gas emissions become the primary factor for the global warming, whereas carbon dioxide (CO2), as one of the primary greenhouse gases, takes an inescapable responsibility for climate change. Currently, various energy conservation and carbon emission reduction technologies, including the carbon capture and storage (CCS) technology, as well as other clean, low-carbon energy exploitation technologies exhibit a rapid development trend to alleviate the growing crisis of climate change. Other than traditional CO2geological storage, a novel geoengineering approach of CO2geological utilization and storage, named CO2geological storage combining with deep saline water/brine recovery (CO2-EWR), is put forward to solve the dilemma between the increasing carbon emissions from coal chemical industry and national energy and water security in China. Compared with the traditional CCS technology, CO2-EWR has two advantages: (1) it can control the relief of reservoir pressure and water production by a reasonable design of pumping wells to achieve the security and stability of the large-scale geological storage of CO2; (2) it can collect and process deep saline water after a treatment for life drinking, industrial and/or agricultural utilizations to alleviate the water shortage situation as well as ecological environmental problems, and in addition, the deep brine resources may create considerable profit margins by cascade extraction, which could be used to fill the gap of cost primarily criticized from capture and sequestration processes of current CCS technologies. China mainland can be partitioned into three potential CO2-EWR zones primarily according to different types of aquifer system, whereas considering research and development maturity and cost prediction of the potential technology adopted, it can be found that coal power and coal chemical enterprises in China's western region have an early opportunity. Three sub-modules of CO2-EWR technology including CO2storage in deep saline aquifer, saline water extraction and desalination as well as brine resources utilization are analyzed from a prospective of energy conservation, carbon emission reduction and environmental friendship. Through detailed analyses, it can be concluded that CO2-EWR technology can be absolutely considered as a clean technology for environmental improvement and green development, and finally development direction and future prospective of the CO2-EWR technology are pointed out.
