Clean Hydrogen Production, Storage, and Utilization
高効率CO2フリー水素製造・貯蔵・利用

In order to realize the hydrogen society, highly efficient hydrogen production, storage, and utilization systems are modeled and analyzed based on the concepts of exergy recovery and process integration. The hydrogen production employs chemical looping which is able to separate CO2 and produce highly pure hydrogen.

将来の水素社会の実現に向けて、高効率な水素製造・貯蔵・利用システムを検討し、エクセルギー回収およびプロセス統合技術によって全体のシステムにおけるエネルギー効率を最大化する。水素製造システムでは次世代変換技術であるケミカルルーピングを採用し、CO2の分離および高純度の水素製造が同時に行うことができる。

Energy Management System and Utilization of Electric Vehicles in Grid Ancillary Services
エネルギーマネジメントシステム・電気自動車の高度利用

The distributed electric vehicles (EVs) potentially provide ancillary services (e.g. frequency regulation) to the grid, especially when they are aggregated. The utilization of EVs results in a very responsive ancillary service compared to conventional regulators. In addition, advanced utilization of reused battery from EVs is also studied in terms of its potential for energy storage, regulators, etc.

将来的に分散されている電気自動車はアグリゲーションシステムによって電力系統へのアンシラリーサービス(周波数調整など)を提供することができる。電気自動車を利用することで、従来型の周波数調整装置と比較し、非常に速い応答の周波数調整が得られた。また、電気自動車からのリユース電池に関する高度利用についても研究対象となる。
