When Expo 2025 opens in Osaka on April 13 it will offer visitors a look at some of Japan’s latest renewable and clean energy solutions.

Hydrogen will feature heavily, with a full green hydrogen supply chain at the NTT and Panasonic Group pavilions among the highlights. On the way to the Expo, visitors will be able to ride Japan’s first commercial hydrogen-powered ferry, operated by Iwatani. Hydrogen, along with carbon capture and reuse (CCU) technologies, will also be part of a methanation demonstration operated by Osaka Gas.

In addition to powering hydrogen production, solar will be on display with perovskite cells (PSCs) from Panasonic and Sekisui Chemical supplying renewable energy. As costs for these flexible photovoltaic cells come down, they significantly expand the potential for solar power’s adoption in heavily urbanized areas.

Another solution on display will highlight the opportunities in the nexus of clean energy and digital tech innovation. Domestic telecoms giant NTT is showcasing a concept that seeks to replace electrical circuitry with photonics, claiming both efficiency gains and a lower demand for energy to sustain it.
