This study proposes a framework for incorporating electrolysis-based hydrogen facilities into Environmental Impact Assessment, informing future policies for green hydrogen deployment.
Among various hydrogen production methods, renewable energy–powered water electrolysis is widely regarded as the most ideal option due to its carbon-free and environmentally sustainable nature. South Korea’s First Basic Plan for the Implementation of the Hydrogen Economy promotes the expansion of electrolysis facilities, including large-scale green hydrogen production within major renewable energy clusters and the commercialization of offshore wave- and wind-powered hydrogen plants.
Accordingly, this study investigates the environmental impacts of electrolysis facilities and proposes key considerations and evaluation methods for their application in Environmental Impact Assessment (EIA). Water usage is a critical factor, as electrolysis systems require substantial amounts of high-purity treated water, necessitating assessment of local supply capacity and long-term resource management. In terms of resource circulation, appropriate strategies are needed for handling precious-metal catalysts and spent electrolyte waste. Site selection should account for renewable energy availability, water supply stability, accessibility to hydrogen demand centers, and infrastructure readiness, while prioritizing the use of existing facilities to minimize environmental disturbance. Local community acceptance must also be secured through safety assurance, transparent communication, and participatory business models.
The findings of this study are expected to support the development of standardized EIA criteria for future green hydrogen production facilities.
Dr. Hyun-Jin Choi is a senior research fellow at the Korea Environment Institute (KEI), focusing on air quality management, environmental impact assessment, and climate change.
