Abstract： In the process of cognition and exploration of the ocean, underwater observation and detection equipment is the necessary facility to enter and detect the ocean. These types of equipment provide technical support for the development and utilization of marine resources and is an important grip for the implementation of China’s marine strategy and the construction of a strong marine country. However, limited by the current level of energy supply, the underwater equipment has problems such as single operation capacity and short single endurance time, which cannot meet the needs of long-term operation under complex working conditions. As the development of marine resources and the defense of sea frontiers in various countries in the world are becoming more and more intense, the construction of transparent marine engineering and submarine factories urgently need to build intelligent underwater equipment clusters, and urgently need energy and power support with high energy density, high safety, high reliability, and long life. Therefore, we need to innovate the underwater energy supply model, build a powerful underwater energy base station with multiple complementary functions of “generating, storing, transmitting, and using”, and overcome the technical bottleneck of underwater energy supply, Providing sufficient energy and power for intelligent and clustered underwater equipment to better assist the construction of China’s marine capability.

Abstract： Energy storage is one of the important supporting technologies to achieve the “dual carbon” goals, and it is an important means to stabilize renewable energy fluctuations and reduce the impact of large-scale new energy access on the power grid. At present, the competition of global energy resources is becoming increasingly fierce, and China is also facing significant changes in the adjustment of energy structure. To implement the energy strategy of “four revolutions and one cooperation” in the new era, and to realize the “14th Five-Year Plan” as well as the “Long-range Objectives Through the Year 2035”, China needs to build a new system of energy structure with Chinese characteristics, driven by “clean, low-carbon, safe and efficient” energy resources. Achieving the complementary integration of clean energy and fossil energy is the key to building a new “clean, low-carbon, safe and efficient” energy system. The development of large-scale energy storage technology is not only a necessary measure for the low-carbon and clean power system, but also a powerful means to seize the strategic commanding heights of the international energy technology and ensure national energy security.

Abstract： The marine area is a strategic area of China. To build China into a strong maritime country, we should enhance the capacity for exploiting marine resources, develop the maritime economy, protect the marine ecological environment, and resolutely safeguard national maritime rights and interests. Promoting marine science and technology to achieve high-level scientific and technological self-reliance is an inevitable requirement for accelerating the construction of maritime country. The marine scientific observation and exploration is the basic means of understanding the ocean, and is also an important basis for the marine resources development, environmental protection and rights and interests protection. This paper reviews the important progresses of global and national ocean observation and exploration program and network, with a view to highlight the practice of ocean scientific observation and exploration technology system construction in Chinese Academy of Sciences, and puts forward thoughts and suggestions on next steps. To build up China’s strength in ocean scientific observation and exploration technology system, we should further strengthen the top-level design to drive the “twin engines” of national strategic needs and frontier trends in science and technology, redouble efforts on developing scientific and technological breakthroughs to make continued efforts to solve the most urgent key problems, and innovate improve institutions and mechanisms to make full use of China’s strategic science and technology capabilities in the marine field, so as to provide strong scientific and technological support for the construction of China as a maritime power.
