The Smart Energy Week 2026 event in Chiba, Japan, serves as a platform for showcasing decarbonization and energy management technologies. Early preparations highlighted domestic innovations, such as Blossom Energy’s graphite thermal energy storage boiler designed to stabilize energy costs and Higo Bank’s ‘Tansaku-kun’ software for visualizing greenhouse gas emissions.

As the event approaches, South Korean renewable energy and nuclear power companies are actively targeting the Japanese market to capitalize on Japan’s Green Transformation (GX) investment plan. Supported by the Korea Energy Agency and KOTRA, South Korean enterprises are presenting technologies including solar hybrid systems, perovskite solar cells, and small wind power generators. These efforts aim to engage major Japanese firms like Hitachi and Toshiba, driven by rising demand for power equipment from the expansion of semiconductor factories and data centers.
