China Economic Herald, China Development Network Song Guanzhou, Wang Lei, Zhang Jianpei, and reporter Yin Mingbo reported that in recent years, Tai'an City, Shandong Province has strengthened the exploration and practice of new energy storage based on its resource advantages, geographical advantages and location advantages, and initially built pumped storage and salt caverns. The energy storage system is supported by energy storage and gas storage, with electrochemical energy storage, hydrogen production energy storage, heat storage and cooling storage as the auxiliary energy storage system. Base.
Based on advantages, develop pumped hydro storage.Tai'an is based on Mount Tai and Mount Culai, which are superior pumped storage site conditions in East China, and vigorously develops pumped storage.Among them, the first phase of the Taishan pumped storage power station has been completed, which is the first pumped storage power station in Shandong and the fourth pumped storage power station in China, with a total installed capacity of 1 million kilowatts, with peak regulation, frequency regulation, phase regulation, energy storage, system backup and black start " "Six functions", with the advantages of large capacity, system-friendly, economical and reliable, ecological and environmental protection.In 2021, the power station of the first phase of the Taishan pumped storage project will generate 960 million kWh of electricity annually, with a comprehensive energy storage efficiency of nearly 80%, meeting the huge demand for energy storage for large-scale access to new energy.At present, the second phase of Taian pumped storage power station is under construction, with a total installed capacity of 1.8 million kilowatts. At present, an investment of 500 million yuan has been completed, and it is striving to realize the first unit to generate electricity within four years.At the same time, Taian is actively exploring the layout of small and medium-sized pumped storage power stations. After all are completed, the total pumped storage capacity will reach 5 million kilowatts, making it an important pumped storage base in East China.
Relying on resources to develop salt cavern energy storage."Activating" the idle salt cavern, among which compressed air power generation is a vivid practice of Tai'an's exploration of innovative new energy storage.The Dawenkou Basin in Taian is the largest rock salt deposit in Shandong. After years of mining, a goaf salt cavity with huge volume and good airtightness has been formed, which can be used for comprehensive development of gas storage, energy storage and salt mining.In addition, Taian has good conditions for power transmission and reception, and the "Longdian Electricity into Shandong" is located in Dongping County, and the nearby local energy storage capacity is strong.Relying on good resources, Taian vigorously develops salt cavern energy storage.In September 2021, China Reserve National Energy Feicheng 10,000-kilowatt compressed air energy storage power station was connected to the grid for power generation. This is the "first set" of compressed air energy storage power stations in China, filling the gap in the international non-combustion compressed air energy storage technology.At the same time, China Reserve National Energy’s 3×100,000 kilowatt compressed air energy storage has been included in the Shandong energy storage demonstration project in 2022.China Energy Construction Digital Group plans to build a 6×300,000-kilowatt compressed air energy storage power station project. The first phase of the construction of a 2×300,000-kilowatt compressed air energy storage power station is undergoing preliminary preparations and is expected to start construction in September.The gas storage group project for natural gas storage in salt caverns with a storage capacity of 1 billion cubic meters is currently carrying out pilot storage experiments, geological exploration and feasibility study preparation.In addition, Tai'an is speeding up the preparation of the comprehensive utilization plan for salt cavern energy storage and gas storage.After all are completed, a salt cavern compressed air energy storage power station with a capacity of 6 million kilowatts and a large-scale salt cavern gas storage project group of 1 billion cubic meters will be formed.
Extend the chain to develop multiple energy storage.In order to strengthen the energy storage industry system and promote the high-quality development of energy storage, Tai'an is striving to extend the chain to develop multiple energy storage.The development of hydrogen production and energy storage has focused on building the Huaneng Xintai photovoltaic hydrogen production base demonstration project, which has been included in the second batch of key hydrogen energy projects in Shandong; relying on ASUS Energy Technology Co., Ltd. to develop solid-state hydrogen storage, hydrogen fuel emergency ) power supply, etc.Highlight electrochemical energy storage and promote the 100 MW/200 MWh energy storage project of Guoneng Shiheng, which has been listed as an energy storage demonstration project in Shandong in 2022; The Heningyang 200 MW/400 MWh energy storage project is being actively promoted.Focusing on energy reserves, focus on the construction of 600,000 tons of LNG localization expansion and gas storage projects in Fanzhen, and build an inland LNG reserve base; make full use of resources such as existing reserve bases and closed mine land, and accelerate the promotion of coal storage and distribution in Luxi and Dongping. The construction of land port coal storage and other projects will increase the city's coal storage capacity to 3.9 million tons.Expand the lithium battery industry, build a lithium battery industrial park based on Feicheng, focus on building a full life cycle industrial chain of "lithium concentrate processing-basic lithium salt-positive and negative electrode materials-battery component assembly-waste battery recycling", and focus on building a "Taishan Lithium Valley" ".
