"The grates that are being welded are about to be sent to Vietnam. Yesterday, Li Jun, vice president and professor-level senior engineer of China Tianying Co., Ltd., introduced that under the strategic background of "environmental protection + new energy" two-wheel drive, China Tianying developed new gravity energy storage technology, successfully entered the new energy industry, and completed the construction of the whole industrial chain in the field of new energy.

China Tianying is a large-scale international listed company engaged in zero-carbon environmental protection and new energy, smart city and environmental services, and renewable resource utilization. In recent years, through the integration of upstream and downstream resources, the company has opened up a development route integrating wind power generation, photovoltaic power generation, gravity energy storage, green hydrogen, green ammonia and green alcohol preparation, and successfully mastered key core technologies such as large-tonnage grate furnace, plasma and gravity energy storage. Up to now, the company has won more than 100 provincial and ministerial honors such as "National Manufacturing Individual Champion" and "Provincial First Set of Major Equipment Certification", and 670 authorized patents at home and abroad, ranking first in the industry in terms of the number of patents.
China Tianying has always adhered to the development concept that technological innovation is the primary productive force, and has established R&D centers in Europe, America and Asia to maintain the company's advanced technology at the forefront of the world's environmental protection industry. Gravity energy storage technology can store different forms of energy such as wind and solar energy in the form of potential energy, and convert them into electrical energy when needed. "In the process of development, the company has always hoped to find an energy storage technology with high conversion efficiency, long sustainable time, high safety and efficiency, and can provide moment of inertia. Li Jun said that through in-depth research, they found that gravity energy storage can meet the expected needs, so they set up a technical research project team, which covers more than 10 specialties such as electricity, materials, structure, machinery, and algorithms.
In the process of research and development, the management of China Tianying decided to provide sufficient research and development funds and equipment support for the project, organized the research and development team led by the deputy chief engineer to tackle key problems, and finally succeeded in research and development after in-depth research on the core principles, optimization of the layout form, optimization of the automatic control algorithm system, ensuring compliance with technical standards and realizing the localization of building materials and equipment.
On September 26, 2023, the main body of the first gravity energy storage technology application demonstration project in China was successfully capped
At the beginning of 2023, China's Tianying gravity energy storage technology will be industrialized, and the construction of the world's first 100 MWh gravity energy storage demonstration project will be launched in Rudong. The total investment of the project is 650 million yuan, the power generation power is 25 megawatts, and the sustainable power generation time is 4 hours. At present, the project is in the process of equipment installation and commissioning. Gravity energy storage technology is one of the effective means to promote the consumption of new energy, as a new energy optimal allocation of energy storage, it can adjust and interact with each other in a larger time scale and spatial range, achieve efficient utilization, reduce wind and solar curtailment, and at the same time can effectively stabilize the output fluctuation of wind power and photovoltaic power generation, improve the ability of the power grid to accept renewable energy, and can provide frequency and peak regulation services for Jiangsu power grid. The Rudong gravity energy storage project discharges 100,000 kWh back and forth for 8 hours.
The horizontal trolleys will be sent to the Rudong base for the world's first 100 MWh gravity energy storage demonstration project
Under the "dual carbon" goal, green, efficient and low-cost new gravity energy storage technology will play an important role in supporting the construction of new power systems. Li Jun said: "After preliminary technical verification, gravity energy storage technology has been recognized, and the technology is more mature. China Tianying's safe, efficient and low-cost new gravity energy storage system will be the best choice to fill the gap in the current market demand. ”
