CTGR(SH:600905) 中国能源报·2025-11-27 12:13Core Viewpoint - The first integrated demonstration project for green hydrogen "production, storage, transportation, and refueling" by the Three Gorges Group has successfully completed debugging, focusing on key technologies in hydrogen production, storage, transportation, and refueling, thereby promoting high-quality development of China's hydrogen energy industry [2]. Group 1: Project Overview - The project is led by the Three Gorges Research Institute and covers the entire process of "green electricity to hydrogen—multi-dimensional storage and transportation—multi-scenario application," creating a closed-loop system for green hydrogen [2]. - Located in Ulanqab City, Inner Mongolia, the project leverages the region's abundant solar and wind resources, aiming to integrate the green hydrogen industry chain with renewable energy consumption challenges [2]. Group 2: Hydrogen Production - The project employs Proton Exchange Membrane (PEM) electrolysis technology to match the volatility of wind and solar resources, designed for renewable energy consumption and load regulation [3]. - The system features a second-level response capability, effectively adapting to the intermittent and fluctuating output of renewable energy [3]. Group 3: Storage and Transportation - The project addresses industry challenges related to the low density, storage difficulty, and high costs of hydrogen by implementing a multi-pressure level hydrogen storage system [3]. - It includes the development of a liquid hydrogen expansion machine and the construction of low-temperature liquid hydrogen tanks capable of meeting a 7-day storage requirement, exploring the technical path for collaborative storage and transportation of high-pressure gaseous hydrogen and liquid hydrogen [3]. Group 4: Refueling and Application - The project has established a hydrogen refueling testing platform that operates reliably in extreme conditions, such as -30°C, and supports automated control throughout the refueling process [4]. - It meets the testing requirements for two mainstream pressure levels of hydrogen refueling stations (35 MPa and 70 MPa) and includes a 200 kW/120-hour hydrogen fuel cell combined heat and power storage system, validating the application potential of green hydrogen as a zero-carbon energy source [4]. - The Three Gorges Research Institute has received approval for multiple national demonstration projects, providing important technical support and practical experience for building a new power system [4].
