The Institute of Advanced Energy conducts research and development in the field of energy science and technology, with a particular focus on zero-emission energies. Its principal aims include the exploration of innovative energy sources—from renewable energy to fusion energy—and the development of systems for efficient energy utilization. Its undertakings include bidirectional research into fusion energy in collaboration with the National Institute for Fusion Science (NIFS). The institute promotes collaborative research within the energy science community as a Joint Usage/Research Center for Zero-Emission Energy Research.
The institute comprises three divisions: the Advanced Energy Generation Division, Advanced Energy Conversion Division, and Advanced Energy Utilization Division, and one research center: the Laboratory for Complex Energy Processes, which promotes inter-division research. The institute's faculty also serve as teaching staff in the Graduate School of Energy Science.
