Carbon neutrality has been suggested to overcome the global climate crisis caused by global climate change. Hydrogen energy is a major way to achieve carbon neutrality, and the developments and policies of hydrogen technology have been proposed to achieve this goal. To commercialize hydrogen energy resources, it is necessary to understand the overall value chain composed of hydrogen production, storage, and utilization and to present the direction of technological developments. In this paper the hydrogen strategies of major countries, including Europe, the United States, Japan, China, and South Korea will be analyzed, and hydrogen technologies by value chain will also be explain. This paper will contribute to understanding the overall hydrogen policy and technology, as both policy and technology are summarized.

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.

Hydrogen is getting more attention owing to the seriousness of air pollution and dependance on oil import, UNCCC(United Nations Convention on Climate Change) for reducing the emission of $CO_2$. This fact is not confined in a certain country but global recognition and several countries initiated R&D competition for commercializing the hydrogen fuel cell vehicle. Within 20${\sim}$30 years cost effective hydrogen production can be possible using fossil fuels because so much research is carried out up to now. But it is so far to produce the most of the hydrogen using renewable resources considering the present status of R&D and cost effectiveness. Several automobile companies planed for mass production of hydrogen vehicle by 2010 but changed or canceled the plan owing to the difficulty of R&D and the low status of infrastructure penetration. This paper surveyed the hydrogen energy policy, R&D program and commercialization strategy of advanced country, international agency, automobile and energy company to analyze the global status of R&D and policy. And the survey of R&D program is focused on the part of hydrogen production, storage, delivery and fuel cell.

The present carbon-based energy system will not last long due to its environmental and economical drawbacks. Hydrogen energy attracts more attention recently and seems to have large ripple effect on economy providing its technical, environmental and economical problems are solved. This paper analyses the situation changed from fossil to non-fossil energy system and the R&D policies of advanced countries by reviewing the world energy status and the energy policy of foreign countries. Finally, the R&D strategy of hydrogen energy technology was developed through analyzing the present states of energy research policy and programs of major countries.

Hydrogen is emerging as an essential material for carbon neutrality. In particular, Korea needs 22.9 million tons of imported clean hydrogen by 2050 to achieve carbon neutrality. However, a large amount of carbon is emitted during the import process, and market regulations are being discussed. This research estimates the carbon emissions of importing green hydrogen from Vietnam, Australia, and the United Arab Emirates to Korea, and calculates imported green hydrogen prices under carbon emission market regulations.

Recently, the world has been considering hydrogen energy as the primary energy transition means to achieve carbon neutrality by 2050. In order to achieve the goal of reducing greenhouse gas emissions, Korea is also promoting a clean hydrogen economy. However, it is necessary to introduce various clean hydrogen from overseas so that the projected demand can not meet the domestically produced. For this study, we conducted the policy comparison approach between countries other than the generally considered technical and economic approaches. The finding proposes the direction of bilateral cooperation for a strategy of securing overseas clean hydrogen from a geopolitical perspective. Germany was a target country for the policy comparison since it has a high proportion of manufacturing, like Korea, and is taking the lead in the renewable-based energy transition policy. According to the survey and analysis of the policy establishment status and new projects of the two countries, Germany is promoting bilateral international cooperation in the hydrogen area with about 33 countries based on 7 types of activities. In comparison, Korea is involved in bilateral cooperation with about 12 countries on relatively few activities. Among the types of bilateral cooperation, R&D cooperation with advanced countries for hydrogen technology was a common activity type. Germany preemptively promotes cooperation for demonstration and commercialization, considering geopolitical means and strengthening manpower training and assistance on policy and regulation to preoccupy the market for the future. Therefore, it is necessary to consider establishing a network of an entire life cycle of supply and demand network that links the future market with securing clean hydrogen considering the geopolitical distribution. To this end, Korea also needs to expand bilateral cooperation countries by activity type, and it seems necessary to seek various geopolitical-based bilateral cooperation and support measures for developing countries to diversify the supply sources of hydrogen.

As one of the alternative solution for energy and environmental issues such as climate change, energy security, oil price, etc., hydrogen energy has been getting so much attentions these days. This paper analyzed the $CO_2$ emission, costs, and energy consumptions when the hydrogen energy was introduced to transportation, specifically in Sedan sector using the energy system model, MARKAL. As results, 21.5% of $CO_2$ emission in 2040 could be reduced and additional 76 billion dollars will be needed in the high energy price scenario. The amount of energy saving mainly due to the replacement of existing car to hydrogen vehicle was 16% of the final energy consumption in 2040.

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.

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.

After reviewing the current status of hydrogen buses and hydrogen charging stations in the United States, as well as related laws and programs, it was found that the federal and state governments supported the supports of hydrogen buses and the deployment of hydrogen charging infrastructure through various policies and programs. In order to promote the spread of domestic and overseas hydrogen buses and hydrogen charging infrastructure, it is necessary to develop and apply various legal systems and programs that can provide incentives to hydrogen bus manufacturers, hydrogen charging station installers, hydrogen bus operating organizations and entities. It is necessary to develop and apply various legal systems and programs that can provide incentives to hydrogen bus manufacturers, hydrogen charging station installers, hydrogen bus operating organizations and entities.
