中国在江苏省正式投运全球最大的压缩空气储能设施，这标志着该国在稳定绿色能源电网方面取得重大技术里程碑。该设施由哈尔滨电气集团开发，利用地下盐穴存储压缩空气，提供长时储能解决方案。
哈尔滨电气集团近日宣布，其位于江苏省的盐穴示范项目第二机组实现满负荷发电并投入全面商业运行。这一设施代表了长时储能技术的重大进步，由两个300兆瓦非补燃储能机组组成，总储能容量达2400兆瓦时，转换效率高达71%，位居世界领先水平。
项目完全融入区域电网后，预计每年发电7.92亿千瓦时，可为约60万户家庭提供稳定电力供应。同时，该设施每年可减少标准煤消耗25万吨，减排二氧化碳60万吨，具有显著的环境效益。
这一投运正值中国储能行业爆发式增长期，该行业已成为支撑风能和太阳能等间歇性能源快速扩张的关键缓冲。中国政府设定到2027年底新建新型储能装机容量超过180吉瓦的目标，推动盐穴压缩空气等创新储能方法的浪潮，使中国成为下一代能源基础设施的主要试验场。
