South Korea’s big move to hydrogen society

Abstract Extensive energy consumption has become a major concern due to increase of greenhouse gas emissions and global warming. Hence, hydrogen has attracted attention as a green fuel with zero carbon emission for green transportation through production of electric vehicles with hydrogen fuel cells. South Korea has launched a hydrogen society policy with the objective of expanding production of hydrogen from renewable energy sources. The hydrogen economy will play a critical role in reducing atmospheric pollution and global warming. However, new development of infrastructure for hydrogen refueling and increasing awareness of the hydrogen economy is required together with reduced prices of hydrogen-driven vehicles that are promising options for a sustainable green hydrogen economy.
