AB - Hydrogen co-firing and hydrogen-fired power generation are considered key options for reducing greenhouse gas emissions from existing LNG-based power plants in the transition toward carbon neutrality. However, the use of hydrogen changes combustion characteristics and emission profiles, revealing limitations in current environmental impact assessment (EIA) frameworks developed for conventional fossil fuels. This study reviews and organizes key EIA considerations for the extension of hydrogen co-firing and hydrogen-fired power generation, focusing on air quality and greenhouse gas emissions, social acceptance, and safety management systems. While hydrogen utilization is expected to significantly reduce carbon dioxide emissions, potential increases in nitrogen oxides due to elevated combustion temperatures and the need to manage emerging emission species such as nitrous oxide under specific combustion conditions are identified as critical issues. Accordingly, the study emphasizes the importance of optimizing combustion conditions, conducting detailed emission assessments, and reviewing the adequacy of existing air pollution control systems. In addition, transparent disclosure of environmental impacts and strengthened safety management are highlighted as essential for improving social acceptance. The findings provide directions for improving EIA frameworks to support sustainable fuel transition and carbon neutrality goals.
