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.

    Project summary:2050年のカーボンニュートラル実現に向けて、液体水素冷却高温超電導発電機の技術開発を行う。液体水素で超電導界磁コイルを冷却し、蒸発した低温ガスで常電導電機子を冷却した後に水素ガスタービンに送って発電するシステムを構築することで、液体水素の冷熱を余すことなく活用したゼロエミッションな発電システムを実現し、水素社会構築に貢献する。
    Awarding organization：NEDO
    System name：先導研究プログラム／エネルギー・環境技術先導研究プログラム

  • Project year：2022.04 - 2023.03
    Title:次世代超電導マグネット向け高温超電導大電流集合導体の開発
    Project summary:カーボンニュートラルに向けてCO2排出量の約4割を占める電力部門の削減は必須である。短期的には、グリーンな液体水素の冷熱を用いて高効率な超電導発電機を冷却し、蒸発した水素ガスをタービンに送って発電する水素ガスターン超電導発電機を実用化して、低効率な火力発電を置き換えることでCO2排出量を減らす。長期的には、究極のカーボンフリー発電である小型核融合炉によりカーボンニュートラルを達成する。このような次世代超電導マグネット機器には高温超電導線材を用いた数kA級の大電流集合導体が不可欠だが、国内で開発・製造を行っているメーカーはなく、機器の実用化開発の進捗の妨げになっている。このため、次世代超電導マグネット機器に不可欠な高温超電導大電流集合導体の設計・製造技術を開発し、国内の機器メーカーに供給可能なことを検証する。
