The hydrogen economy is still a niche market and a new system. If we believe in the optimism and the hope of human history of technological progress, the hydrogen economy will be a new paradigm to replace the carbon economy. The research question is what kind of leadership the government should show in order to revitalize the hydrogen economy. In response to the research question, this study highlights the governance leadership. The new economy must be newly recognized before they can find a solution. This research can be the first step in finding the way.

The Korean government is actively promoting the hydrogen industry as a key driver of economic growth. This commitment is evident in the 2019 hydrogen economy activation roadmap and the 2021 basic plan for hydrogen economy implementation. This study quantitatively analyzes the economic impact of the hydrogen economy using input-output analysis based on the Bank of Korea's 2019 input-output table, projecting its size by 2050. Four parts dealt with production-inducing, value-added creation, employment-inducing, and wage-inducing based on a demand-driven model. The results reveal that transportation had the most remarkable economic effect throughout the hydrogen economy, and production was the least. The hydrogen economy is projected to reach 71.2 trillion won by 2050.

Hydrogen, which can be produced from abundant and widely distributed renewable energy resources, seems to be a promising candidate for solving the concerns for improving energy security, urban air pollution, and reducing greenhouse gas emissions. The two primary motivating factors for hydrogen economy are fossil fuel supply limitations and concerns about global warming. But the safety issues associated with hydrogen economy need to be investigated and fully understood before being considered as a future energy source. Limited operating experience with hydrogen energy systems in consumer environments is recognised as a significant barrier to the implementation of hydrogen economy. To prevent unnecessary restrictions on emerging codes, standards and local regulations, safety policies based on real hazards should be developed. This article studies briefly the direct impact-distances from hazard events such as hydrogen release and jet fire, and damage levels from hydrogen gas explosion in a confined space. Based on the direct impact-distances indicated in the accident scenarios and consumer environments in Korea, the safety policies, which are related to hydrogen filling station, hydrogen fuel cell car, portable fuel cell, domestic fuel cells, and hydrogen town, are suggested to implement hydrogen economy. To apply the safety policies and overcome the disadvantages of prescriptive risk management, which is setting guidance in great detail to management well known risk but is not covering unidentified risk, hybrid risk management model is also proposed.

This study evaluated the effect of improving the atmospheric environment based on the premise that the supply of hydrogen fuel cell vehicles (HFCV) will be achieved as many as the number of vehicles presented in the hydrogen economy activation roadmap announced by the Korean government in January 2019. The HFCV supply target (2.7 million passenger cars) suggested in the hydrogen economy revitalization roadmap was logically allocated to the five major metropolitan areas in Korea. Air pollution damage costs by region were calculated by reflecting the basic unit of damage cost to the estimated air pollutant emissions. As a result, it was confirmed that the benefits per unit of some cities in Gyeonggi-do were derived more than major cities in the metropolitan area.

미국, 유럽, 중국, 일본 등 주요 선진국은 탄소 경제에서 수소 경제로의 전환을 위해 다양한 수소 경제 정책을 발표하며 연구역량을 집중하고 있다. 우리나라도 이러한 추세에 발맞추어 2019년 초 수소 경제 활성화 로드맵을 발표한 이래로 수소 경제 관련 법안을 마련하고 지원책을 실시하고 있다. 본 연구에서는 국가과학기술지식정보서비스(NTIS)의 국가R&D과제정보 최근 10년치 데이터를 활용해 수소 경제, 그중에서도 전·후방 파급효과가 크다고 할 수 있는 연료전지전기차 관련 R&D 현황과 지식구조를 파악하고자 한다. 연료전지전기차 관련 국가R&D과제(2020년 1월 기준) 1,479개의 원시 데이터를 바탕으로 네트워크 분석 및 텍스트 마이닝을 실시한 결과, 연료전지전기차 분야에서는 수소의 생산, 운반, 저장, 활용의 전 프로세스에 걸친 기술 및 시스템의 연구개발이 활발하게 이루어지고 있는 것으로 나타났다. 본 논문은 해당 연구결과를 통해 현재 연료전지전기차 산업을 선도하고 있는 한국의 수소 경제 관련 정책 수립과 연구개발, 시장 전략에 대해 시사점을 제시한다.

As the hydrogen era comes near future, hydrogen fuel cell vehicles are core of hydrogen economy. Until now, Korea has 17 hydrogen refueling stations but 9 hydrogen refueling stations have been retired already and 8 hydrogen refueling stations are still running. With a limited number of hydrogen refueling stations, it is very difficult to get scientific data for the economy of hydrogen refueling stations in Korea. Thus, based on NREL(National Renewable Energy Laboratory) study, we analyzed most recent data for the construction of hydrogen refueling stations in one specific site in Korea. The cost comparison data between Korea and USA shows 14% difference, saying higher costs of Korea. Korea looks 5 years delay compared to USA. This data will be an important tool for the investment from every industrial parties.

Korea is showing its appearance as a leading country in the hydrogen economy by establishing policies for revitalizing the hydrogen economy and enacting the 「Hydrogen Economy Promotion and Hydrogen Safety Management Act」 for the first time in the world. In addition, domestic hydrogen facilities are using hydrogen energy safely through world-class safety management compared to overseas advanced countries. However, in order to enhance the safety of the rapidly diversifying hydrogen industry and rapid technology development, such as the introduction of liquefied hydrogen, some institutional improvements are needed. In this regard, this paper intends to analyze the results of safety inspections on 13 representative facilities and prepare safety improvement plans to establish preemptive safety measures.

The Hydrogen Economy Promotion and Hydrogen Safety Management Act (hereinafter referred to as the "Hydrogen Economy Act") stipulates matters related to certification and cancellation of clean hydrogen by grade, and requires those who produce, import, or sell clean hydrogen to report to the Minister of Trade, Industry and Energy. In order for this system to operate smoothly, the clean hydrogen Certification system must be designed to meet international standards, and the institution operating the System must have appropriate capabilities and foundations. The clean hydrogen certification system should serve as an opportunity for Korea's domestic energy industry to take a leap forward.

The rapid changes of energy environment such as high oil price, united nations framework convention on climate change, and the hydrogen economy have been happening to provide national energy security in the 21st century, we need to build strategic approach for coping with energy environment. From a long-term viewpoint of energy technology development, it's time to develop energy technology with selection and specification. In this study, we build energy technology roadmap for establishing the hydrogen economy with a long-term strategy. We analyze economic spin-offs and commercial potential for establishing energy technology roadmap of energy technology development for establishing the hydrogen economy.
