Establishing an integrated safety management system…Active support for hydrogen technology standards and localization technology
[에너지신문] In accordance with the government’s roadmap for promoting hydrogen economy, a total of 2.9 million hydrogen vehicles and 1,200 hydrogen charging stations are planned to be supplied by 2040 to expand the hydrogen economy through the supply of hydrogen vehicles in stages and establishment of hydrogen infrastructure.
However, in the early stages of activation of the hydrogen industry, some facilities are experiencing breakdowns and operation interruptions due to the lack of technology and operation experience for the overall hydrogen industry, which is raising public discomfort and anxiety.
In particular, the domestic hydrogen infrastructure is led by products from overseas manufacturers, so it is difficult to take immediate action if there is a problem in operation after the construction is completed, and the manufacturer directly performs the maintenance work for facilities that have passed the warranty period, but this is a basic maintenance level. When a problem occurs, it is difficult to quickly respond for stable operation of the facility due to excessive action time and lower maintenance efficiency.
In a situation where the frequency of shutdowns of hydrogen charging stations due to frequent facility failures is increasing and complaints about facility companies’ responsiveness are increasing, there is no dedicated agency that can stably manage the domestic hydrogen facility infrastructure.
However, the Gas Technology Corporation, a public institution that has established a standardized maintenance system and specialized technology for domestic high-pressure natural gas facilities, is striving to establish a domestic hydrogen infrastructure wide area maintenance service system for the success of the hydrogen economy and the green new deal. It is observed that it will greatly contribute to the stable settlement of the industry.
Currently, the Gas Technology Corporation is building 20 hydrogen charging stations and 2 hydrogen production bases nationwide as a domestic hydrogen infrastructure construction project, and is focusing on expanding hydrogen infrastructure such as the construction of hydrogen liquefied hydrogen production facilities in Gangwon Province and Pyeongtaek City. .
In addition, through the establishment and consignment operation of the Hydrogen Cycle Product Safety Support Center in the International Science Business Belt Complex, it is supporting the localization of core parts of the domestic hydrogen cycle and the growth of the materials and parts business.
In addition, on July 14th, in line with the government’s announcement of the Korean version of the New Deal, K-water preemptively established the’K-New Deal’ promotion team and a dedicated organization on July 28, The’New Deal Strategic System’ has been established, and among them, the’Hydrogen Infrastructure Wide Area Maintenance Service Construction’ has been selected as a voluntary proliferation project by the government-related ministries joint’Strengthening the role of public institutions to support the Korean version of the New Deal’.
Gas Technology Corporation’s’Hydrogen Infrastructure Wide Area Maintenance Service System Construction’ project is in line with the core concept of K-New Deal, and is being promoted with three strategies in accordance with the future energy and digital transformation era.
The first is the establishment of a nationwide optimal maintenance system using existing infrastructure.
Gas Technology Corporation currently operates 14 branches and 8 business offices nationwide, and plans to build a hydrogen wide-area maintenance system consisting of 9 regions nationwide through three stages by 2023 based on these advanced maintenance personnel, equipment, and expertise. to be. With this plan, a maintenance support system capable of emergency maintenance and preventive maintenance within 2 hours will be established in any region of the country. In addition, the H-EOCS (Emergency Maintenance System), which enables emergency dispatch and maintenance 24 hours a day, is introduced, and preventive maintenance and maintenance. The safe operation of hydrogen infrastructure facilities will be promoted through emergency response procedures and training of experts.
The second is the establishment of an integrated safety management system for the entire cycle of hydrogen infrastructure.
It is a strategy to increase facility safety and facility management productivity throughout the life cycle of hydrogen infrastructure through a digital twin based on big data, the core of the future 4th industrial revolution. To this end, it has already begun to build an IoT-based real-time integrated safety management system for hydrogen infrastructure facilities in Daejeon headquarters in December, and plans to expand the integrated maintenance & operation center and material management center in stages. Through such an integrated safety management system, real-time condition monitoring, emergency response management, and integrated facility management are possible. In particular, predictive maintenance, accident prevention and reliability improvement through real-time big-data-based AI simulation are planned.
The third is hydrogen technology standardization and active support for hydrogen localization technology.
Based on the accumulated technology and experience of design, construction, and maintenance so far, KDHC established a standardization model for construction of domestic hydrogen infrastructure facilities, and completed standardization of maintenance and operation technologies together to lead technology standardization that is not limited to equipment manufacturers. It aims to contribute to vitalization of the domestic hydrogen industry ecosystem.
In addition, in connection with the hydrogen full-cycle product support center project currently being built in the International Science Business Belt, the domestic material and parts industry is promoting the localization of 10 key imported parts for hydrogen infrastructure facilities from 42% to 78%. It plans to drive the growth of the company.
Recently, as part of these efforts, a hydrogen charging station charging nozzle freeze prevention device has been developed, which is receiving good response from charging station operators and hydrogen vehicle drivers. This technology is currently being applied to two charging stations, and plans to continuously expand the application to promote safer hydrogen charging.
In addition, in cooperation with domestic SMEs, the development of an explosion-proof hydrogen leak image detection device was initiated. Existing gas leak detection devices notify leaks through alarms, but it is difficult to determine the cause and location of gas leaks in real time, but the technology developed this time is the first explosion-proof product in Korea, and hydrogen leaks at the exact location through real-time ultrasonic image detection. It is expected to maximize the safety and maintenance efficiency of hydrogen facilities by eliminating the safety blind spot at the site through detection and enabling emergency maintenance and initial response.
KOGAS announced that this company-wide’Hydrogen Infrastructure Wide Area Maintenance Service System Construction’ not only contributes to the stabilization and activation of the domestic hydrogen industry, which is the core of the Korean Green New Deal, but also a successful new deal of the government in the era of future energy and digital transformation by incorporating the digital new deal It is being promoted with a plan to promote the business and achieve future growth of the corporation at the same time.
