Description
Liquid hydrogen serves as an excellent medium for transporting hydrogen, a clean energy source for the next generation. Also, its atmospheric boiling point (20 K) is well-suited to the operating environment of high-temperature superconducting equipment; thus, a synergistic effect between the liquid hydrogen—acting as both an energy source and a coolant—and the superconducting equipment enables the realization of highly efficient systems. This presentation provides an overview of liquid-hydrogen-cooled high-temperature superconducting rotating machines, covering their fundamental concepts, applications such as in aircraft and liquid hydrogen pumps, and future prospects.
