【摘要】 CPGS结合了CO₂地质封存和深部地热开发2种技术的优势，在实现地热能开采的同时，也对CO₂进行了地质封存，从而实现了温室气体减排和可再生能源利用技术的结合，CO₂的排放在最大限度上减少。介绍了增强型地热系统和CO₂羽流地热系统，对比分析了水和CO₂作为传热工质的优缺点，同时详细地介绍了CO₂羽流地热系统的国内外研究现状以及研究需要改进之处。最后介绍了3种CO₂羽流地热系统发电应用技术，即热伏发电、有机朗肯循环发电技术、基于以太阳能为辅助热源的CPGS-sCO₂布雷顿联合循环发电技术。更多还原

【Abstract】 CPGS combines the advantages of CO₂ geological storage and deep geothermal development technologies to achieve the geological storage of CO₂ while mining geothermal energy, thereby achieving a combination of greenhouse gas emission reduction and renewable energy utilization technology, and minimizing CO₂ emissions to the greatest extent possible.In this paper, the enhanced geothermal system and CO₂ plume geothermal system were introduced, and the advantages and disadvantages of water and CO₂ as heat transfer working fluids were compared and analyzed.At the same time, the research status of CO₂ plume geothermal system at home and abroad and the research needs to be improved were introduced in detail.In the end, three kinds of CO₂ plume geothermal system power generation application technologies were introduced, namely, thermal power generation, organic Rankine cycle power generation technology, and CPGS-sCO₂ Brayton combined cycle power generation technology based on solar energy as auxiliary heat source.更多还原
