Core Viewpoint - Marine energy is becoming a crucial area in international energy competition, with major economies like the EU, UK, and the US aiming to develop it as the next offshore energy industry after wind power. China is accelerating the large-scale development of marine energy, targeting an installed capacity of 400,000 kilowatts by 2030 [1][21]. Group 1: Marine Energy Development - Marine energy, derived from physical ocean processes such as tides, waves, and ocean currents, includes tidal energy, wave energy, temperature difference energy, and salinity difference energy [1]. - China's marine energy utilization is still in the industry cultivation stage, with significant advancements being made in experimental setups to explore the synergy between wind and wave energy [3][5]. - The LHD tidal energy station in Zhoushan has achieved a generation capacity of over 6 million kilowatt-hours, marking a significant milestone in tidal energy development [10][12]. Group 2: Technological Innovations - The LHD tidal energy project employs a modular design that allows for easy maintenance and replacement of components, significantly reducing operational costs [18]. - Advanced technologies have been developed to withstand severe weather conditions, such as typhoons, and to ensure long-term stability in energy generation [15][18]. - The project has seen a reduction in the cost of electricity generation from 106 yuan per kilowatt-hour in its first generation to 1.1 yuan in the fourth generation, with ongoing efforts to further decrease costs [26][30]. Group 3: Future Prospects - A new 100-megawatt tidal energy station is set to begin construction in Zhoushan by the end of this year, which is expected to generate 610,000 kilowatt-hours daily, sufficient for the energy needs of over 8,000 households [21][25]. - The establishment of a "mother port" for tidal energy in Zhoushan aims to create a comprehensive marine energy industry cluster, enhancing the development of technology, equipment, and services [34]. - The continuous operation of the LHD tidal energy generator for over eight years has set a global record, positioning China as a leader in tidal energy technology [32].
