At present, the cement market is in the doldrums, the price of cement is at a low level, and the survival of enterprises is becoming more and more difficult. It has become an urgent need for enterprises to effectively achieve energy saving and carbon reduction, reduce operating costs and enhance their competitiveness. Under the background of "double carbon" goal, 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.
Energy storage power stations
are gradually increasing their development in the field of new energy, and Conch Group has used factory buildings to build roofs and open spaces 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. Jiang Yi, academician of
the Chinese Academy of Engineering and director of the Building Energy Conservation Research Center of Tsinghua University, said that flexible power consumption and distributed power storage are important ways to solve the problem of wind and solar energy consumption, and are also the key and key points to establish a stable and reliable zero-carbon power system. It is no wonder that cement companies are so "devoted" to energy storage.
However, in the view of the energy storage industry, cross-border energy storage enterprises need to invest a lot of money in technology research and development, and the energy storage industry chain is long, enterprises need a clear positioning. In the critical period of the outbreak of the energy storage industry, cross-border enterprises entering the energy storage track need to tailor their clothes and design their own development path.
To this end, China Cement Network will hold the "2023 Cement'Double Carbon 'Conference and the 10th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference" in Zhengzhou, Henan Province. The cement industry is moving towards a low-carbon, more energy-saving and greener high-quality development.
At the same time, the medal ceremony of "2023 Advanced Enterprises of Double Carbon in Cement Industry" and the "Double Carbon" Equipment Exhibition will be held. After the meeting, we will also organize a visit to Jiyuan Zhonglian Cement Co., Ltd. "The world's first production line of carbon sequestration auxiliary cementitious materials and low-carbon cement from flue gas CO2 of steel slag capture cement kiln".
