Abstract
This article outlines basic situation of combustible ice, and describes briefly current situation of global exploration and development methods for combustible ice and geothermal energy.Taking CO2 application technology as the starting point, a joint technology containing carbon dioxide injection cycle heat exchange (CO2-EGS)-carbon dioxide replacement combustible ice (CO2-CH4)-carbon dioxide storage (CCS) is proposed.The advantages of the joint technology are analyzed from many factors, and its deficiencies and challenges in technology, investment, geological risks, and environmental protection are summarized.Its development prospects are also given.
