Energy Systems Utilizing Thermodynamic Characteristics of Carbon Dioxide near the Critical Point

The critical point refers to the point at which a substance undergoes a second-order phase transition, characterized by the divergence of second derivatives of free energy, such as heat capacity. The critical point is one of the peculiarities of matter, and in its vicinity, various unique behaviors of physical properties are observed. Some of these behaviors are engineering-wise very useful and find active applications in semiconductor purification, dyeing, extraction, and other industries. From the perspective of energy systems, the changes in various thermodynamic properties near the critical point offer high applicability, and there is ongoing research and development in multiple aspects, focusing on power generation systems and energy storage systems. This presentation discusses the development trends and key required technologies of energy systems that leverage the thermodynamic characteristics of fluids near the critical point.
