Under the guidance of the goals of carbon peak and carbon neutrality, the mainland's energy structure is accelerating its transformation. According to the latest data released by the China Electricity Council, in the first three quarters of this year, the growth rate of new installed capacity of solar power and wind power in mainland China reached 145% and 74% respectively, and the growing new energy is accelerating towards a more low-carbon green future.
At the Zhangpu Liuao Offshore Wind Farm in Fujian Province, the hoisting of wind turbines is underway, and the project includes 28 wind turbines of 13 MW and above, including 6 wind turbines of 16 MW, which is also the largest offshore wind turbine with the largest single capacity and the largest impeller diameter in the world. The 16-megawatt wind turbine hub is 152 meters tall in the center, equivalent to the height of a 52-story building, and the individual blades are 123 meters long.
In the waters off Fujian, a 16-megawatt wind turbine can generate about 34 kilowatts of electricity per revolution. According to this calculation, it can output more than 66 million kWh of green electricity every year, which is equivalent to meeting the annual living electricity of 36,000 families of three. In the dispatch hall of the local power grid, this green electricity can be directly reached by new technologies such as blockchain.
However, there is a time difference between the volatility and randomness of wind power and the demand for electricity in cities, and new solutions are being explored for newly built energy storage facilities.
CCTV reporter Pingfan: After the wind power from the sea is dispatched through the power grid, it comes to the battery swap station behind me to provide battery swap services for local operating vehicles, which is like a large urban power bank, charging the battery swap station at night and providing battery swap services during the peak during the day.
Master Fan, a taxi driver in Xiamen, goes to the battery swap station every afternoon to change the battery, and it only takes 3 minutes to replace two standardized batteries each time, and the power is 53 kWh.
In Xiamen, the battery swap infrastructure network is under construction, and each battery swap station uses the same standard battery to adapt to different vehicle models.
Another new energy reverse charging technology is also being promoted in Xiamen, using new V2G charging piles to turn electric vehicles from means of transportation into "charging treasures", and reverse power transmission to the grid, and there are currently 56 charging piles that can provide this service.
Reverse charging technology will expand the application of electric vehicles in grid load peak regulation and emergency response. Electric vehicles can transmit 30 degrees of electricity per hour, which can meet the daily electricity needs of 8-10 households. In the field of new energy, a large number of new technologies, new formats and new models are emerging, which will provide new momentum for industrial development.
Yang Kun, executive vice president of the China Electricity Council: the development of new quality productivity in the energy and power industry is to vigorously cultivate new industries, new formats, and new models, including technological innovation represented by the integration of source, grid, load and storage, multi-energy complementation, new energy storage, hydrogen energy, etc., and the "14th Five-Year Plan" and "15th Five-Year Plan" will increase the scale of new power investment in the country to more than 10 trillion yuan, of which the new energy industry will play an important role.
National Energy Administration: Build an innovation chain for the new energy industry and cultivate new economic momentum
Looking forward to the future, how to cultivate new quality productivity in the energy field? What kind of new momentum will the upgrading of the industrial chain stimulate? In this regard, we also interviewed He Yang, deputy director of the National Energy Administration, to listen to his interpretation.
Since the beginning of this year, the mainland's new energy industry chain has repeatedly broken world records. The world's first 16 MW domestic offshore wind turbine has been successfully connected to the grid for power generation, the 18 MW offshore model will be rolled off the assembly line by the end of the year, and the onshore 15 MW model has been released. The conversion efficiency of photovoltaic high-efficiency cells continues to improve, with the conversion efficiency of China's mass-produced advanced high-efficiency cells reaching 25.5%, the highest efficiency of crystalline silicon cells being developed reaching 26.81%, and the conversion efficiency of crystalline silicon-perovskite tandem cells reaching 31.8%.
He Yang, Deputy Director of the National Energy Administration: We must continue to consolidate and enhance the international competitiveness of the mainland's new energy industry, seize the commanding heights of new energy development technology in the future by strengthening wind power, photovoltaic, cutting-edge and disruptive technology research, and promote the technological innovation and application of new energy engineering in major projects such as large-scale wind power photovoltaic base projects and offshore wind power base projects.
Where is the new momentum for building the future industry in the energy sector? Taking new energy storage as an example, it is also an emerging industry born under the progress of energy science and technology, and has a broad market space in the future. As of the end of September 2023, the cumulative installed capacity of new energy storage projects in operation across the country has exceeded 21 million kilowatts, and the installed capacity of new energy storage projects has exceeded 12 million kilowatts this year.
He Yang, Deputy Director of the National Energy Administration: From the perspective of investment scale, if calculated according to the market price in the same period, the direct investment driven by the new energy storage projects put into operation exceeds 50 billion yuan.
In addition, the mainland will actively cultivate new models and new forms of new energy development, and increase pilot demonstrations of grid-based new energy, renewable energy LAN microgrids, distributed new energy power generation trading, renewable energy off-grid hydrogen production, and ammonia production.
He Yang, Deputy Director of the National Energy Administration: Through these new models and new business formats, a number of zero-carbon power plants and zero-carbon parks will be built to further catalyze and stimulate the new vitality of new energy as a new quality of productivity, and form a new momentum for green and sustainable growth.
