全球二氧化碳排放量的驟然增加進而引起全球氣候暖化是現在全球各國要面對的問題,全球氣候變化小組(IPCC)認為二氧化碳封存(CCS)是一種有效降低二氧化碳溫室氣體的機制,其中又以地質封存方式被認為最有效。地質封存一般是將二氧化碳注入地下一千公尺左右的地下層,如此方式無論是否有地質構造封閉,二氧化碳可以穩定的儲存或溶解在鹽水層中。台灣的二氧化碳排放主要集中在沿海附近,因此合適的二氧化碳的地質封存場也應該在陸海域附近。本計畫是三年計畫的第二及第三年計畫,預期調查台灣濱海區及舊有陸上的油氣礦區調查及評估可能的二氧化碳封存場址。藉由地質調查、地物地化監測、滲透溢流模擬和地質力學模擬的結果,作為未來國家選定二氧化碳封存場址的重要參考依據。 The increasing of global CO2 has increased the problem of global warming. IPCC has considered the method of CCS (Carbon dioxide Capture and Storage) is very good approach to reduce the global CO2 quantity. Among all, the geological storage is considered as the most efficient way. Geo-sequestration is to inject CO2 into a sedimentary layer at ~1000m deep where a saline formation exists. With or without a geological structure of trap, in such a depth the CO2 will be captured or dissolved. In Taiwan, most of CO2 come from the industries or power plants situated in the coastal area of Taiwan. A suitable CO2 storage site could be close to the shore area. However, an appropriate geological condition for each CO2 storage site must be considered carefully. In this second and third year proposal for 3-year project, we want to investigate probable CO2 storage sites along western coastal zone of Taiwan and some existing coal mine or gas field. Our geological survey, geophysical and geochemical monitoring, infiltration overflow simulation, and geomechanical simulation results will provide very useful data and information for the selection of CO2 geological storage sites in Taiwan in the near future. 研究期間:10001 ~ 10012
