Hot dry rock and combustible ice are new high-quality resources. The reserves of dry hot rock resources in China account for about 16.7% of the total resources in the world,and the reserves of combustible ice account for about 70% of the total resources in the world. The development and utilization of hot dry rock and combustible ice resources is of great significance to alleviate the energy shortage of China. The chapter combs the resource types and distribution of hot dry rock and combustible ice resources in China. Hot dry rock and combustible ice in China are mainly distributed in areas with poor natural conditions. The paper summarizes international hot dry rock and combustible ice projects represented by the United States and Japan,finding that the development of international hot dry rock and combustible ice is in the preliminary exploration stage,having not yet realized real commercialization. And,the investment projects of international hot dry rock are gradually decreasing,the international combustible ice project has made new progress. In addition,the paper analyzes the current mainstream mining and utilization technology of hot dry rock and combustible ice,analyzes the development prospect and challenges of hot dry rock and combustible ice,and illustrates that the mining and storage technology of hot dry rock and combustible ice plays a decisive role in its resource prospect.
