Currently, major foreign countries such as Europe, the United States, Japan, and China have established policy and technology goals by 2050 to achieve the hydrogen economy. In line with this, Korea is also preparing to leap forward as a leading country in the world's best hydrogen economy by establishing a technology development target by 2050. In this paper, by examining and analyzing domestic and foreign policy and technology trends to date, implications for domestic hydrogen policy and technology trends are discussed, and major issues and future contents are summarized.

Fuel cell electric vehicles (FCEVs) using hydrogen gas are zero emission vehicles, thus emission measurement for combustion vehicles is not applicable. The hydrogen gas consumption for fuel economy will be measured by the stabilized pressure/temperature method, mass flow method and electrical current method, etc. In this research, weight method with a newly manufactured test equipment is applied to measure the hydrogen consumption because above 3-methods have a deviation. The hydrogen consumption is directly calculated by the weight differences of the external hydrogen tank before and after the chassis dynamometer test. Ultimately the fuel economy for FCEVs is obtained with a deviation less than 1% in all chassis dynamometer tests.

화석연료에 기반을 둔 경제구조에서 수소경제로의 이행은 에너지 안보와 기후변화의 대응이라는 측면에서 중요한 과제이다. 이러한 경제구조의 변환과정에서 발생할 수 있는 파급효과를 사전적으로 분석하는 연구가 필요하다. 따라서 이 논문은 동태 연산일반균형모형을 이용하여 수소에너지 도입이 경제와 환경에 미치는 영향을 분석하였다. 첫째, 수소 에너지 도입은 투자증대와 생산비용의 감소를 통해 GDP 증대에 기여한다. 둘째, 수소에너지와 같은 신재생에너지 도입을 위한 정부보조의 경우 재원마련을 위한 세수증대로 인해 총수요가 감소하는 효과가 있다. 마지막으로 화석연료에서 수소경제로 전환시키는 수소에너지 도입은 이산화탄소 배출을 감소시키는 환경적 효과가 있다 온실가스 감소를 통한 기후변화에 보다 효과적으로 대응하기 위해서는 신재생에너지에 기반을 둔 수소에너지로의 전환이 필요하다. 즉 정부는 지속가능성에 기반을 둔 수소에너지 정책을 추진해야 하며, 향후 신재생에너지에 기반을 둔 수소에너지 도입의 경제적, 환경적 효과를 분석할 필요성이 있다.

Fuel consumption measurement of hydrogen fuel cell vehicle is considerably different from internal combustion engine vehicle such as carbon balance method. A practical method of fuel consumption measurement has been developed for hydrogen fuel cell vehicles. There are three method of hydrogen fuel consumption testing, gravimetric, PVT (pressure, volume and temperature), and mass flow, all of which necessitate physical measurements of the fuel supply. The purpose of this research is to measure the fuel consumption of hydrogen fuel cell vehicles on chassis-dynamometer and to give information when the research is intended to develop test method to measure hydrogen fuel economy.

This paper overviews the concept of the strategic niche management, which emphasises the social aspects of new technologies and calls for relevant government policies for socio-technical transition. Hydrogen energy technologies remain in the niche level, thus the SNM perspective is appropriate to be applied. The reason why, and the way how to see hydrogen as a socio-technical niche are discussed, followed by an analytic argument on hydrogen policies and their SNM characteristics. Final part of the paper deals the design of the socio-technical experiment. It is expected that this paper would contribute to not only policy development but also improving understandings on the socio-technical nature of hydrogen energy of hydrogen community.

It is very important to secure hydrogen acceptability to achieve the hydrogen economy. This study empirically analyzed the factors affecting acceptance by using the results of a questionnaire administered to residents of Jeonju-Wanju Hydrogen Demonstration City. The results indicated that the safety of hydrogen infrastructure and local industry and economic growth positively affected acceptance. In particular, local industry and economic growth were more effective in improving resident acceptance. As policy factors, support for government policies and disclosure of information on projects were also positive factors. As perceptual factors, the higher interest in hydrogen and less safety concerns positively affected acceptability. Therefore, as far as hydrogen safety is concerned, it seems necessary to support local industry development to improve acceptability, disclose information related to industrial development, and introduce targeted experience programs.

연료전지와 수소를 사용하는 연료전지 자동차의 상용화를 위해서는 수소 공급용 수소 스테이션(hydrogen station)의 개발이 중요한 핵심 기반기술이다. 일반적으로 수소 스테이션은 탈황반응, 개질반응(reforming), 수성가스전환(WGS) 반응 및 수소분리(PSA) 장치로 구성된 수소제조 공정과 압축, 저장 및 분배 장치로 구성된 후처리(post-treatment) 공정으로 구성되어 있다. 본 총설에서는 수소 경제(hydrogen economy) 사회로의 진입을 위해 국내외에서 연구개발 중인 수소 스테이션에 대한 연구 개발 동향과 전망을 고찰하였다. 그리고 향후 풍력 및 태양열 등 재생 가능 에너지(renewable energy)원으로부터 물의 분해에 의한 수소제조 기술이 확립되기 전까지는 화석연료의 개질 반응이 수소를 제조하는 핵심기술이 될 것으로 판단된다. 따라서 화석연료의 탈황반응, 화석연료의 개질 반응에 의한 수소제조, CO 농도 저감을 위한 수성가스 전환반응 및 수소의 분리기술 등 수소 스테이션의 상용화에 필수적인 단위공정개발에 대한 최근의 연구동향을 정리하였다.

The aim of this study is to evaluate the economic feasibility of domestic on-site steam methane reforming (SMR) hydrogen refueling stations. We evaluated the levelized cost of hydrogen (LCOH) for the SMR hydrogen refueling stations, which have production capacities of 100 kg/day (SMR 100), 200 kg/day (SMR 200), and 500 kg/day (SMR 500) utilizing the scale factor. The main results indicated that the LCOH of SMR 100, SMR 200, and SMR 500 were 14,367 won/kg, 11,122 won/kg, and 8,157 won/kg, if the utilizations of hydrogen stations were 70%. These results imply that the production capacity of the domestic SMR hydrogen station should be greater than 500 kg/day to compete with other hydrogen stations when we consider the current sale price of hydrogen at the hydrogen stations.

Hydrogen, as a future energy source, is thought as an alternative of fossil fuel in view of environment and energy security. Hydrogen has the properties of both fuel and electricity so that it can make the energy paradigm shift in the future. Therefore, researches on hydrogen in power system area are essential and urgent due to their huge effects on current paradigm. In this paper, the visions and technical challenges of hydrogen in power system are reviewed as energy storage, dispersed generation (DG), DC generator, and combined heat and power (CHP).
