Core Viewpoint - The first coal-to-natural gas project in Northeast China, the Datang Fuxin project, has achieved significant progress with the completion of its first phase, aiming to enhance energy supply stability for five cities and promote local economic development [1][3]. Group 1: Project Overview - The Datang Fuxin coal-to-natural gas project will supply natural gas to Shenyang, Tieling, Fushun, Benxi, and Fuxin, benefiting a population of 15.96 million [1]. - The project has achieved over 98% localization in equipment manufacturing, reducing costs and increasing project control [1]. Group 2: Environmental and Economic Impact - The project will convert 7.5 million tons of low-quality coal into 1.33 billion cubic meters of natural gas annually, with an energy conversion efficiency of 57.59%, the highest in the industry [3]. - It is expected to create over 2,000 jobs, providing a strong boost to the local economy [1]. Group 3: Strategic Importance - The project will complement the China-Russia East Route Natural Gas Pipeline, enhancing the resilience and stability of regional energy supply during extreme conditions [1]. - It represents a breakthrough in industrial import substitution, reducing reliance on foreign technology and converting high carbon emission brown coal into cleaner natural gas [3].
