The study focuses on the need to enhance safety protocols for the utilization of hydrogen and ammonia as clean energy sources in South Korea. Experts have highlighted the risks associated with these fuels, ranking hydrogen as the riskiest, followed by ammonia and LNG. The current legal framework in Korea is found to have limitations, with gaps in coverage for the entire hydrogen business sector and weak regulations for hydrogen and ammonia usage. Recommendations include enacting a stand-alone Ammonia Act, strengthening safety manager qualifications, and improving regulatory and technical standards. An expert survey further emphasized the importance of emergency response drills, criteria enhancement for safety managers, and classifying ammonia as a hazardous material. The study advocates for the establishment of comprehensive safety management systems through extensive research before commercializing power plants using these new fuels, aiming for a decarbonized society and reduced carbon emissions in South Korea.
