Correspondents Geng Jianrong and Bi Pengcheng report.
A few days ago, at the production site of Dongying Kunyu 2GWh liquid-cooled energy storage digital production line located in Dongying Economic and Technological Development Zone, the robotic arms were flipped up and down and cooperated with each other, and the transported battery cells were rolled off the assembly line one after another after fully automatic feeding, stacking, laser cleaning and welding.
It is reported that this production line is the first liquid cooling production line in Shandong Province and the first batch of domestic liquid cooling production lines invested and constructed by Dongying Kunyu in 2023. The lithium iron phosphate battery energy storage system produced by it optimizes and improves the air-cooling technology with liquid cooling technology, and integrates many advanced technologies for the first time, which solves the technical problems of low battery safety and short cycle life caused by the low heat exchange efficiency, slow cooling rate, increased cell temperature, and large temperature difference between battery cells in the industry, and provides strong technical support for the national construction of a new power system and dual carbon strategy.
In 2022, the first batch of 40MW 80MWh liquid-cooled energy storage system delivered will be applied to the 500MW photovoltaic sand control project in Linze, Gansu Province of China Energy Group, which can save 520,000 tons, reducing carbon dioxide emissions by 1340,000 tons, sulfur dioxide emissions 10540,000 tons. "Introduced by the on-site staff.
The new energy and energy storage industry is one of the leading industries in Dongying Economic and Technological Development Zone. In recent years, in the process of actively responding to green, low-carbon and high-quality development, the development zone has continued to promote the conversion of old and new kinetic energy, accelerated the optimization and upgrading of industrial structure, boosted the technological transformation and upgrading of enterprises, strictly managed the "two highs" project, seized the opportunity of high-end casting policies, and the energy efficiency of enterprises in the zone has reached 73% higher than the benchmark level. In 2023, Dongying Economic and Technological Development Zone was successfully selected into the pilot list of industrial parks for the construction of green and low-carbon high-quality development pilot zones in Shandong Province, and was first included in the list of provincial and national green industrial parks, bringing green and low-carbon development to a new level.
This year, Dongying Economic and Technological Development Zone will continue to do a good job in green and low-carbon development, accelerate the implementation of three projects such as Zhongjin Copper's capacity integration, Jinlei Phase II, and Hongfeng Intelligent as soon as possible, and continue to promote the construction of HG15 offshore photovoltaic and Shanneng independent shared energy storage projects, and at the same time, with the help of new energy projects such as HG14 and Shanneng energy storage, increase the proportion of renewable energy in the energy structure of the park, innovate and build a "zero-carbon" emission pilot, and accelerate the layout of photovoltaic, energy storage, hydrogen energy, Green ammonia and other new energy equipment manufacturing industry chain, to build the province's first-class 100 billion new energy equipment manufacturing industrial base.
