Overview

This technology area aims to promote renewable energy as our primary power source, develop innovative technologies for utilizing hydrogen energy, and advance energy storage technologies that are essential to supporting the transition to a sustainable energy system.
In the energy conversion field, in addition to low-cost, highly efficient, and convenient technologies for converting solar energy, we will promote low-cost, energy-efficient technologies for the synthesis and utilization of hydrogen energy carriers.
In the energy storage field, we will promote energy storage technologies that utilize waste heat in the low to medium temperature, as well as more versatile, economical, and environmentally friendly energy storage technologies for a wide range of applications, ranging from small-scale energy storage devices used in our daily lives to large-scale energy storage devices for power grids that promote the use of renewable energy sources with highly variable output.
From the perspectives of energy and material flows, we also place emphasis on the contribution of these technologies to reducing greenhouse gas emissions throughout the entire process of their utilization.
