"The lack of independent technology research and development capabilities, weak equipment manufacturing capabilities, and technology and equipment production rely mainly on imports." This is one of the main manifestations of China's current renewable energy technology development capabilities and weak industrial system, but this situation is expected to change in the future.
The National Development and Reform Commission recently issued the "Eleventh Five-Year Plan for Renewable Energy Development" (hereinafter referred to as the "Planning"). "Planning" clearly puts forward the overall objective of "improving R&D capability and industrialization level of renewable energy technologies". In addition, the "Planning" also put forward guidance on technical equipment and industrial development for hydropower, biomass, and wind power. This indicates that the development of renewable energy technology equipment and industries will be substantially promoted.
Strengthen technological reform and strengthen independent innovation of hydropower
In order to promote technological equipment and industrial development, the "Planning" pointed out that in the area of â€‹â€‹hydropower, the technical level of hydropower survey, design, construction, management, and equipment manufacturing will be further improved and improved, with a focus on strengthening high-dam construction under 300-meter high dams and complex geological conditions. Technical research on dam technology, large-scale underground caverns and high slope anchoring technologies, key technologies for flood discharge and energy dissipation at high heads, etc.; continue to promote the localization of large-scale conventional hydropower units and pumped-storage units to digest and absorb foreign advanced technologies. At the same time, it strengthened independent innovation, strengthened technological transformation, and carried out research on the design and manufacturing technology of 60,000 kilowatts or more of tubular, million kilowatt-class Francis turbine units and 300,000 kilowatts of pumped storage units, resulting in autonomous knowledge. Property rights of hydropower equipment manufacturing technology.
Research and development of large-scale biogas power generation equipment
In terms of biomass energy, the â€œplanningâ€ requirement for power generation equipment is: during the â€œEleventh Five-Year Planâ€ period, on the basis of pilot projects, through the introduction of digestion and absorption and re-innovation, agricultural straw biomass and other forestry biomass are organized. Equipment R&D and manufacturing of power generation and waste power generation, mastering biomass power generation technology; grasping the development and production of large-scale biogas power generation equipment, forming a series of products with 500 kW, 1,000 kW, etc.; grasping a small scale of 50-200 kW The supporting R&D and manufacturing of biomass gasification power generation equipment has formed specialized equipment production and supporting capabilities, and has improved technical standards and testing and certification systems.
The requirements for the development of biogas technology and equipment are: research and development of dedicated technologies and equipment for the recovery and utilization of landfill gas, improvement of production processes and equipment technologies for large and medium-sized biogas projects, and the formation of more comprehensive biogas equipment and construction capabilities.
In addition, the research and development of straw baling and loading equipment, shrub logging and transportation special equipment, various special equipment for biomass solid forming and processing, and focusing on industrialization and standardization work are also involved in the â€œplanningâ€.
Wind power equipment is mainly made in China
To improve wind power technology research and development capabilities, the "planning" pointed out that during the period of the "Eleventh Five-Year Plan", China will continue to promote the large-scale application of mass-produced domestically-made wind turbines, and realize the upgrading of MW-class wind turbines. Based on the preliminary formation of domestic manufacturing equipment capabilities, adopting technology introduction, joint design, independent innovation, etc., mastering integrated manufacturing technology for wind turbines of 1.5 megawatts and above, and developing offshore wind turbines of 3 megawatts. We will give full play to China's advantages in electromechanical equipment manufacturing, make full use of domestic and international markets, and cultivate wind power equipment supporting parts and components manufacturing industries with high technological level and strong market competitiveness.
In the promotion of solar energy technology equipment and industrial development, "Planning" pointed out that through scientific and technological research, industrialization support, as soon as possible to grasp the high-purity polysilicon material production technology and processes to achieve large-scale production. Through pilot project construction, technology introduction and digestion, absorption and innovation will be carried out to grasp the key technologies of solar thermal power generation.
