General aspects of gaseous hydrate and recent research in the field of cool storage using gaseous hydrate are reviewed. Experimental studies have been performed to investigate the influence of supercool degree, stirring, surface active agent, and history of the reactants on the kinetic characteristics of phase change processes of gaseous hydrates formed with R141b and R142b. The temperature time diagrams of hydrate formation processes are recorded. It was found that a quicker phase change process should appear in the reactants deeper supercooled, or charged with proper surface active agent, or accompanied with proper stirring, and the history of the reactants have a complicated function for phase change processes of gaseous hydrates.
