The Korea Institute of Machinery and Materials (KIMM) has developed a groundbreaking Hydrogen-fueled Combined Heat and Power (CHP) System for smart greenhouse agriculture in Jeonju, South Korea. This innovative system integrates hydrogen fuel cells, solar thermal collectors, heat pumps, and adsorption chillers, reducing CO₂ emissions by over 50% and cutting operating costs by more than a third compared to conventional greenhouse systems. By combining PEM fuel cells, air-source heat pumps, solar collectors, and adsorption chillers, the system efficiently produces and supplies energy, utilizing waste heat for cooling and heating. The integrated control system optimizes energy flows between heat sources, enabling stable energy production regardless of external weather conditions. Notably, the system has demonstrated a 36.5% reduction in operating costs and a 58.1% cut in CO₂ emissions, showcasing its economic viability and environmental benefits. The successful cultivation of tomatoes for an extended period in the demonstration greenhouse underscores the system's efficiency and stability in greenhouse agriculture, paving the way for energy self-sufficiency. KIMM's establishment of the Future Agricultural Bioengineering Division reflects its commitment to advancing agricultural technologies, particularly in energy, resource management, and digital transformation, with support from national green hydrogen and smart farm innovation programs.
