OHYA MASAYOSHI

Title
Associate Professor
Research Fields, Keywords
High Temperature Superconductor, Liquid Hydrogen, High Magnetic Field, Power Transmission
Research Outline
With the future hydrogen society in mind, we are working on the development of superconducting devices that utilize the cold heat of liquid hydrogen to save energy. By linking superconducting system networks, such as superconducting generators and superconducting cables, with green liquid hydrogen derived from renewable energy, we aim to create a sustainable decarbonized society.
