液体水素冷却 SMES と燃料電池で構成する非常用電源

抄録

Environmental problems are an urgent subject to be solved for humankind. Hydrogen is clean and carbon dioxide (CO2) free, and superconducting devices have energy-saving merits. The combination of liquid hydrogen (LH₂) and superconducting devices provides an environment-friendly system. We propose an emergency power supply composed of LH₂-cooled superconducting magnetic energy storage (SMES) and fuel cells. The power supply is intended to be used for building such as hospitals; fully utilizing the merit of LH₂ as a high-density energy reservoir and that of SMES as a quick-response power supply. In this paper, the system configuration, development scenario and design of the system are described.
