Xin Hua She·2025-11-26 11:13Core Insights - The China Petroleum & Chemical Corporation (Sinopec) has successfully implemented the 45MPa high-pressure hydrogen storage well technology at its integrated hydrogen refueling station in Chongqing, marking a significant breakthrough in high-pressure underground hydrogen storage technology and commercial operation in China [1][2]. Group 1: Technology and Innovation - The underground hydrogen storage solution addresses the challenges of hydrogen storage in mountainous cities, saving approximately two-thirds of the land area compared to traditional ground storage facilities [2]. - The 45MPa high-pressure hydrogen storage well is innovatively designed to be vertically buried underground, providing a new solution for hydrogen infrastructure in similar regions [2]. - The technology has received three national patents and has been included in the 2024 Chongqing major technological equipment promotion directory [2]. Group 2: Operational Efficiency - The integrated hydrogen refueling station has been in safe and stable operation for over 1,500 days, supplying more than 400 tons of hydrogen [1]. - The station has a daily hydrogen supply capacity of 1,000 kilograms, sufficient to meet the refueling needs of approximately 100 hydrogen fuel cell vehicles [2]. - Refueling a vehicle with 12 kilograms of hydrogen takes only 10 minutes, with a cost of 25 yuan per kilogram, allowing for a driving range of about 550 kilometers per full tank [2]. Group 3: Supply Chain and Infrastructure - The hydrogen source for the station is derived from the by-product hydrogen from Sinopec's Chuanwei Chemical, which is purified to 99.999% purity and transported through a complete localized supply chain [5]. - The supply chain includes hydrogen production, purification, transportation, and refueling, providing solid support for the construction of the "Hydrogen Corridor" in the Chengdu-Chongqing region [5].
