全球单机最大压缩空气储能项目冲刺并网

Core Viewpoint - The development of long-duration energy storage technologies, particularly compressed air energy storage (CAES), is crucial for building a new power system, with the "Energy Storage No. 1" project in Shandong being a significant focus due to its innovative non-combustion technology and large scale [1][3]. Group 1: Project Overview - The "Energy Storage No. 1" project, led by China Energy Engineering Group, features a 350 MW CAES system, which is the largest single-unit capacity globally and aims to achieve full capacity grid connection by the end of 2025 [1][5]. - The project utilizes the abundant underground salt cavern resources in Tai'an, transforming them into a giant "energy bank" that stores excess electricity during low demand periods and releases it during peak demand [2][4]. Group 2: Technological Innovations - The project has achieved a breakthrough in "non-combustion" operation, eliminating the need for fossil fuels to heat the compressed air, thus achieving zero carbon emissions and pollution [3]. - The system's design allows for the recovery of heat generated during compression, which is used to enhance the efficiency of energy conversion, further contributing to its environmental benefits [3]. Group 3: Economic and Strategic Implications - The choice of a 350 MW scale is strategic, as it allows for significant contributions to regional grid stability and reduces unit investment costs, enhancing energy conversion efficiency [4]. - The project is seen as a model for activating idle resources and promoting local development, with the potential to utilize over 90% of China's rich salt cavern resources for energy transformation [4]. Group 4: Future Prospects - The project is progressing well, having completed key construction and installation milestones, with a focus on ensuring operational readiness for the planned grid connection [5]. - China Energy Engineering Group aims to leverage its technological and industrial advantages to establish itself as a leader in the global CAES market, contributing to national energy security and the achievement of carbon neutrality goals [5].
