蓝海逐“能”应向全产业链发展

Core Viewpoint - The development and utilization of marine energy is becoming a crucial part of sustainable development strategies globally, driven by environmental concerns and energy security awareness [1][3]. Current Status of Marine Energy Development in China - China has a vast marine area with rich marine energy resources, and as of the end of 2023, the total installed capacity of marine energy exceeds 12,000 kilowatts, ranking fourth in the world [3]. - The government has integrated marine energy development into the legal framework, setting a target of 400,000 kilowatts of installed capacity by 2030 [3]. Technological Achievements in Marine Energy - China has made significant technological advancements in marine energy, including the commercial operation of the Zhejiang Jiangxia tidal experimental power station for over 40 years and the delivery of the first 500-kilowatt wave energy device in 2020 [4]. - The country leads globally in installed capacity for wave energy, tidal current energy, and tidal energy, with substantial engineering experience accumulated [4]. Marine Energy Industry Chain Analysis - The marine energy industry chain encompasses resource development, technology research, equipment manufacturing, engineering construction, operation maintenance, and energy utilization [6]. - Upstream focuses on resource investigation and technology development, while midstream emphasizes equipment manufacturing and engineering construction [6]. Downstream Operations and Energy Utilization - Downstream activities involve the operation and maintenance of marine energy stations, optimizing energy output and integrating marine energy into the grid [7][8]. - The establishment of a comprehensive energy system combining marine energy with desalination, hydrogen production, and energy storage is emphasized to enhance economic viability [8]. Marine Energy Development in Nansha - Nansha District in Guangzhou is positioned to leverage its marine advantages for economic development, with specific recommendations for advancing marine energy [10]. - Key initiatives include conducting resource surveys, enhancing planning and design, and focusing on core technology development through collaboration with research institutions [10][11][12].
