目前,地质储存CO2的途径和方法很多,而地质储存却一直被认为是最有前景的方式之一。该储存方法与其他的方法相比,相对安全、可靠、适应范围广、副作用小。研究表明,有利的、精心设计和妥善管理的地质储存储层,可以储存注入99%的CO2,时间长达千年以上。为了应对全球气候变化的挑战,西方主要发达国家都在大力开展碳捕集与储存项目(CO2的捕集和储存)研究。本文依据收集的CCS的研究资料,概述CO2地质储存的研究现状,提出了一些对我国CO2地质储存工作的启示。
At present, there are many ways and means of geological storage of CO2, and geological storage has been considered as one of the most promising ways. Compared with other methods, the storage method is relatively safe and reliable, has a wide range of application and has small side effects. Research shows that favorable, well-designed and well-managed geological storage reservoirs can store up to 99% CO2 for more than a thousand years. In response to the challenge of global climate change, major western countries have been vigorously carrying out carbon capture and storage projects (capture and storage of CO2). Based on the collected research data of CCS, this paper summarizes the current research status of CO2 geological storage and puts forward some enlightenment for CO2 geological storage in China.
