Abstract:

The development and utilization of marine renewable energy exerts key potential influence on promoting energy conservation,emission reduction and countermeasure for climate change.The reserves of marine renewable energy in China are abundant,and its exploitable amount in offshore waters goes as high as hundreds of GW.In recent years,marine renewable energy development and utilization technology has made rapid development in China,and its installed capacity ranks among the best in the world. The implementation of the energy green transformation strategy under the goals of carbon peaking and carbon neutralization provides a vital opportunity for the development and utilization of marine renewable energy resources in China.Based on the study and important progress made in the development and utilization of marine renewable energy in China,the existing problems and the potential of marine renewable energy in emission reduction are analyzed.Then,the medium and long-term development goals of marine renewable energy in China under the background of carbon peaking and carbon neutrality are made,and its short-term technology development goal and key points in large-scale utilization are proposed.

Key words: marine renewable energy, carbon peaking, carbon neutrality, wave energy, axis tidal energy, vertical tidal energy, temperature difference energy, salinity gradient energy
