Research Institute of Carbon-neutral Energy Machinery

The Research Institute of Carbon-neutral Energy Machinery conducts energy technology development to establish a carbon-neutral energy supply chain. We conduct research on hydrogen liquefaction, liquid hydrogen storage and supply systems, high-efficiency eco-friendly heat pump systems, and high-capacity energy storage systems. In addition, we develop, evaluate the performance of, and certify thermo-fluid equipment, such as compressors, pumps, turbines, and heat exchangers, that are core components for these systems. As a national research institute, we also provide policy planning and development and industrial support for the development of a carbon-neutral energy supply system.
