A study on a political system for the advance in green hydrogen technology: a South Korea case study

Background Hydrogen energy, a type of renewable energy if produced without fossil fuel, has a critical issue in that most of it is still produced from carbon footprint heavy industries such as the fossil fuel industry. It is imperative to produce hydrogen from renewable sources on a global level so that the carbon footprint can be curbed. South Korea, along with other global economies such as the US, the EU, Japan and China, has shown its resolution to build a hydrogen economy with green hydrogen produced only from renewable sources. Since 2017, South Korea has been actively shaping its political actions and policies to develop the necessary technology for this transition. This study focuses on South Korea's actions and policies, using a political system model to better understand the shift towards a green hydrogen economy. Results The analysis shows that budgeting for R&D projects has had a significant impact on scientific breakthroughs, advancements, and product development in the field of green hydrogen in South Korea. These actions have also affected market performance, resulting in increased interest and investment in green hydrogen. Although there have been significant advancements in the field of green hydrogen in South Korea, the current state of technology remains in its early stages of development. Most of the breakthroughs have been in water-to-hydrogen and biomass-to-hydrogen technologies. However, these technologies show promise as the foundation of a thriving hydrogen economy in South Korea. The analysis also indicates a strong market demand for green hydrogen technology. To support these efforts, the political system has focused its financial support on water-to-hydrogen technology and projects at the TRL 1–3 stage. Conclusions The study concludes that ongoing financial and political support is necessary for areas showing outstanding performance to vitalize the hydrogen economy and facilitate the transition to a green hydrogen society in the future. Additionally, a robust legal framework is crucial to ensure steady growth of the green hydrogen economy, similar to those in other major hydrogen economies such as the US and Germany. This study serves as a case study of South Korea, showcasing the impact of political actions on the advancement of scientific technology.
