Development and Utilization of Marine Geothermal Energy in China
Marine geothermal energy is rich in China but have not been well developed.Integrating marine geothermal energy with other marine resources is crucial for ensuring China's energy security,realizing the carbon peak and carbon neutrality goals,strengthening the country's energy sector,building a new energy system,and promoting island and deep-sea development.This study reviews the current status of marine geothermal energy utilization in China and abroad,analyzes the challenges faced by China in marine geothermal energy utilization,and clarifies the key development directions of marine geothermal energy utilization in China:(1)core technologies and key equipment for the exploration and development of marine geothermal energy,(2)core technologies and key equipment for marine geothermal energy utilization,and(3)marine geothermal energy industry and industrial chain construction.Moreover,the study expounds on the staged development goals and proposed two typical models for marine geothermal energy utilization in China:integrated development with offshore heavy oil and with marine natural gas hydrate.Future development strategies are further proposed:(1)coordinating marine function zoning and incorporating marine geothermal energy and offshore oil and gas blocks into unified national planning;(2)pinpointing the distribution of marine geothermal energy in South China Sea and its overlapping advantages with other marine resources;(3)accelerating research on core technologies and key equipment for the development and utilization of marine geothermal energy;(4)increasing financial support and providing subsidies and preferential fiscal and tax policies to fully mobilize the enthusiasm of enterprises;and(5)conducting pilot tests in marine geothermal energy enrichment areas to explore the demonstrations of integrated development with other marine resources.
