Recently, the world's first UHPC energy storage cabinet, independently developed and manufactured by Jurong Taini Cement in Xiashu Town, has been put into operation in Rome, Italy, and the French market cooperation has also been promoted simultaneously. This old building material enterprise, which has been deeply engaged in the cement industry for 80 years, has successfully set sail for the sea through technological transformation and cross-border application of cement material technology to the energy storage track, realizing the magnificent transformation from "selling cement" to "selling systems and material solutions".
Walking into the production workshop of Taiwan Cement Energy Storage Technology (Jurong) Co., Ltd., white UHPC energy storage cabinets are arranged neatly, and technicians shuttle between cabins to carry out equipment assembly operations in an orderly manner. "This production line was officially put into operation in May this year, and 500 energy storage cabinets will be produced throughout the year." Zhang Liang, Manager of Production Planning and Equipment Assurance Department of Taiwan Cement Energy Storage Technology (Jurong) Co., Ltd. How does
cement store electricity? Zhang Liang said that the cement energy storage system does not store electricity in cement, but uses a safety cabinet made of ultra-high performance concrete (UHPC), which integrates battery modules, battery management, temperature control, fire extinguishing and control equipment to form a complete energy storage unit that operates independently.
At present, most of the energy storage cabinets on the market are made of steel. Unlike ordinary concrete used in general buildings, UHPC has the characteristics of high strength, high temperature resistance and high durability, which is used in the curtain walls of the Louvre in Abu Dhabi and the North Courtyard of Palace Museum. "Under the same volume specifications, the carbon emission of UHPC cabinet is reduced by about 40% compared with the general metal energy storage cabinet, and the production cycle of a single cabinet is about 45 days." Zhang Liang said that compared with the traditional steel energy storage cabinet, UHPC also has the characteristics of low thermal conductivity, high compressive strength and fireproof and explosion-proof, which provides a more reliable safety barrier for the energy storage system.
The cement energy storage system is located in the light storage and charging station in Rome, Italy, which can store electricity in the valley of power consumption and release electricity during peak hours. In view of the pain points of difficult expansion and high cost of some old power grids in Europe, it acts as a "power reservoir" between the power grid and the fast charging station, and can support the power demand of the station for ultra-fast charging without large-scale transformation of the power grid.
"At present, the orders in hand have been scheduled to the end of next year, and the production capacity will be increased to 1000 cabinets next year, with an output value of about 150 million yuan." Zhang Liang revealed that the cement energy storage system has a number of international patents, and the products have passed the relevant safety certification of the European Union, successfully entered the European market, and realized the overseas export of China's energy storage technology.
