In recent years, in response to national requirements and industry demand, cement enterprises have begun to seize the "tuyere", accelerate the pace of clean energy substitution, and gradually accelerate the development of new energy sources such as electricity storage. & nbsp; & nbsp;
Energy storage power station is the trend of the times & nbsp; & nbsp;
In 2022, the state successively issued documents such as the Implementation Plan for the Development of New Energy Storage in the 14th Five-Year Plan, the Action Plan for Accelerating the Green and Low Carbon Innovative Development of Electric Power Equipment, and the Guiding Opinions on Accelerating the Development of New Energy Storage. Among them, the Guiding Opinions on Accelerating the Development of New Energy Storage require that by 2025, the installed capacity of new energy storage will reach more than 30 million kilowatts.
In addition, provinces and cities are also gradually accelerating the implementation of energy storage projects, and more than 20 provinces have defined the proportion of supporting energy storage equipment. In May this year,
Zhejiang Provincial Department of Economy and Information Technology and other five departments jointly issued the Action Plan for High-quality Development of Cement and Carbon Peak in Zhejiang Province (2022-2025), which was implemented in June. According to the plan, Zhejiang will build a number of distributed photovoltaic power stations and energy storage power stations on the roofs of large buildings such as steel greenhouses and workshops, which are raw materials for cement enterprises, encourage factories and parks to develop decentralized wind power according to local conditions, and increase the proportion of non-fossil energy consumption. It also promotes the application of distributed clean energy and energy storage integrated system to promote the efficient complementary utilization of multi-energy.
It is understood that Zhejiang will co-ordinate the relevant provincial-level special funds, focus on supporting the energy-saving and carbon-reducing technological transformation of the cement industry, and give priority to the central special funds and provincial-level funds for the projects listed in the central air pollution prevention and control project reserve and the provincial key energy-saving and carbon-reducing technological transformation project plan.
Relevant institutions estimate that the installed capacity of new energy storage is expected to reach 150GW by 2030. According to the 2-hour allocation time, the comprehensive market-oriented energy storage space will exceed 1.2 trillion yuan. & nbsp; & nbsp;
Energy storage market breaks the dilemma of cement energy & nbsp; & nbsp; "Flexible power consumption and distributed power storage are important ways to solve the problem of wind and solar power consumption, and are also the key and focus to establish a stable and reliable zero-carbon power system." Jiang Yi, academician of the Chinese Academy of Engineering and director of the Building Energy Conservation Research Center of Tsinghua University, said. Since
2022, cement enterprises have been deeply troubled by the high coal price and the difficulty of peak power consumption. How to "meet the peak in summer" and solve the problems of high cost and high energy consumption has been the focus of exploration and solution for cement enterprises for many years, and certain achievements have been made. The industrial layout of cement enterprises has begun to show new trends, and new tracks such as energy storage are slowly unfolding. & nbsp; & nbsp;
In April this year, the energy storage power station project of Shimen Cement Company, a subsidiary of China Gezhouba Cement Company, was officially connected to the grid, which is the first energy storage power station of the company.
It is understood that the project operates in the mode of energy management cooperation, uses high-safety lithium iron phosphate batteries, adopts prefabricated cabin design, uses information technology such as energy management system (EMS), adopts the "two-charge and two-discharge" charging and discharg ing strategy, charges in the period of low electricity price, discharges in the period of high electricity price, and discharges in the period of high electricity price. The single maximum storage capacity is 8000 kilowatts per hour, and the daily maximum discharge capacity can reach 16000 kilowatts per hour. It
is estimated that the project will steadily supply 4 million kilowatt-hours of electricity every year and save 2 million yuan of peak electricity charges every year, which will not only reduce costs and increase efficiency for enterprises, but also contribute to the stable operation of the power grid. & nbsp; & nbsp;
Energy Storage Power Station & nbsp; & nbsp; Gradually strengthen the development of new energy field. Conch Group uses factory buildings to build roofs and open space to lay out photovoltaic power generation and energy storage industries.
It is reported that Conch New Energy Company has built more than 90 photovoltaic power stations and energy storage projects, and has achieved full coverage of distributed photovoltaic projects in cement plants. The cumulative installed capacity of photovoltaic and energy storage is close to 500 MW, and the cumulative power distribution in 2022 is nearly 300 million degrees.
Among them, Zhangjiagang Energy Storage Power Station Project is currently a large-scale user-side electrochemical energy storage power station in China, and is also one of the eight energy storage demonstration projects of the State Energy Administration in 2020. Zongyang Conch 6MW/36 MWh all-vanadium flow battery energy storage is the first all-vanadium flow battery energy storage demonstration project of Conch Group. It is also a large-scale all-vanadium redox flow battery user-side energy storage power station in the industry, which has played a guiding and demonstration effect on the popularization and application of domestic user-side energy storage power stations.
In addition, Shangfeng Cement also signed a strategic cooperation agreement with Sunshine New Energy last year, and the parties will cooperate to establish a joint venture company to jointly implement a series of photovoltaic energy storage projects. In the
face of the prominent downward trend of cement demand, the high energy price, the long-term high cost and the continuous compression of profits, cement enterprises have begun to tap the energy-saving potential and expand the application of photovoltaic, energy storage and other technologies, which has become the key breakthrough point for cement enterprises to enhance their comprehensive strength and market competitiveness. On July 6-7,
2023, China Cement Network will hold the " 2023 China Cement Energy Conservation and New Energy Development Conference" in Chongqing. We sincerely invite government leaders, industry technical specialist, research institutes, universities, cement enterprises and equipment suppliers to discuss the application of new energy technologies such as photovoltaic power generation and energy storage in the cement industry.
