Scholar-generated biography
CHANG Daejun is a researcher at KAIST, focusing on liquid hydrogen and energy storage systems. His work explores the characteristics of bio-oil from marine macroalgae pyrolysis, CO2 liquefaction for ship-based carbon capture, and cold energy recovery from liquefied natural gas. He investigates thermodynamic and kinetic hydrate inhibition in natural gas, thermal stratification in cryogenic tanks, and the safety and availability of new propulsion systems for LNG carriers. Chang also examines hybrid systems combining renewables and Li-ion batteries, as well as the economic evaluation of small-scale LNG supply chains using liquid nitrogen for natural-gas liquefaction. His research addresses energy storage, carbon capture, and sustainable propulsion technologies for maritime and industrial applications.
