Energy engineering

Energy engineering

The Korea Institute of Energy Technology, established in 1977, is a national research institute in the field of energy technology and has world-class researchers, faculty, and research infrastructure. The KIER campus consists of four detailed majors: hydrogen energy engineering, renewable energy engineering, clean energy engineering, and energy system engineering. Hydrogen energy is mainly composed of green/blue hydrogen production/storage, fuel cells (booan branches), etc. Renewable energy is mainly focused on solar, solar, wind, marine energy, biomass, secondary batteries, and artificial intelligence-based resource evaluation, and has branches in Buan, Ulsan, Gwangju, and Jeju. Clean energy is mainly focused on greenhouse gas collection, fossil fuel purification, and CCUS, and energy systems are focused on optimizing and efficient convergence systems, and ICT and AI-linked technologies. The KIER campus is training next-generation energy experts with a curriculum that emphasizes field practice and artificial intelligence based on excellent infrastructure.
