Core Viewpoint - The successful trial operation of the gas-hydrogen blending technology project in Yumen City, Gansu Province, marks a significant step in China's exploration of integrating natural gas with new energy sources, addressing the challenges of renewable energy consumption and promoting a green comprehensive energy supply system [1][2]. Group 1: Project Overview - The project is the first demonstration application of gas-hydrogen blending in China and Gansu Province, showcasing the integration of natural gas and new energy technologies [1]. - The project aims to convert excess renewable energy, which cannot be timely transmitted or consumed, into stable hydrogen and related products using advanced water electrolysis technology [1][2]. - The gas-hydrogen blending technology allows for a flexible adjustment of hydrogen blending ratios between 5% and 20% [2]. Group 2: Environmental Impact - The application of gas-hydrogen blending technology is expected to reduce carbon emissions by approximately 1,600 tons annually, equivalent to planting about 80,000 trees, based on a 20% hydrogen blending ratio and an annual gas consumption of 10 million cubic meters in Yumen [2]. Group 3: Strategic Goals - The company aims to deepen cooperation with Jiuquan City in areas such as resource supply, green electricity interconnection, and zero-carbon park construction, establishing a model for enterprise-local government collaboration [2]. - The project supports the transition towards a clean and low-carbon energy structure, contributing to the development of the hydrogen energy industry chain in Gansu Province [2].

Group 1 - The core achievement of the project is the successful trial operation of China's first industrial user gas hydrogen blending project by China National Petroleum Corporation (CNPC) in Yumen, Gansu Province, marking a significant step in the integration of natural gas and new energy [1] - The project aims to address the issue of excess renewable energy in the Jiuquan region by converting surplus wind and solar power into stable hydrogen energy, which is then blended into natural gas pipelines [3][4] - The project has established a comprehensive process for hydrogen blending, transmission, terminal utilization, and trade measurement, creating a technical benchmark for the industry [5] Group 2 - The project is expected to reduce carbon emissions by approximately 1,600 tons annually for the Yumen Chemical New Materials Company, equivalent to planting 80,000 trees, while also optimizing fuel costs by nearly 8% [6] - The hydrogen-blended gas has shown a higher than expected stability in heating value, a 5% increase in combustion efficiency, and a 15% reduction in nitrogen oxide emissions, contributing to both emission reduction and economic benefits [7] - CNPC's ambition is to build a modern energy system integrating oil, gas, heat, and hydrogen, with similar hydrogen blending pilot projects being initiated in other regions such as Xinjiang and Jiangsu [7][8]
