PV Expo and the wider Smart Energy Week wrapped up in Tokyo last week. It revealed ambitious plans for solar and energy storage installations in Japan, including creative approaches to dealing with a severe lack of space for new installations, which should bring plenty of opportunities for domestic and international players.

Executives from Gentari, the clean energy subsidiary of Malaysia’s state-owned oil company Petronas, and Japan’s biggest steelmaker, Nippon Steel, are eying Australia for future investments in renewables projects and green-steel manufacturing.

Australian startup Relectrify aims to scale up the adoption of its highly efficient and cost-effective battery storage technology after attracting financial backing from a group of international heavyweights including Japanese car giant Toyota’s venture capital firm.

Australian energy software provider Evergen will take its solar and battery optimisation technology to Japan after teaming with Japanese companies Sharing Energy and Sassor on a pilot project to explore how to best commercialise distributed energy resources, including rooftop solar and residential battery energy storage systems, in Japan.

Panasonic claims that its new vehicle-to-home system can increase the self-consumption rate of residential solar and storage capacity to 90%.

Japanese scientists have described the steps that need to be taken to improve the average efficiency of CIGS solar modules, from around 18.5% at present to more than 20%. They presented all of the critical technical factors that are currently holding the tech back from broader market adoption.

Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.

Scientists in Japan have developed a novel metal-organic, framework-based magnesium ion conductor with superionic conductivity, even at room temperature.

The system is reportedly able to refill about eight hydrogen fuel cell vehicles, each in three minutes. It is also able to supply electric power by using hydrogen produced with renewable energy within the station.

Japan’s Rinnai has unveiled what it claims is the world’s first 100% hydrogen combustion technology for residential water heaters. It is currently using the hydrogen water heater in demonstration projects in Australia, prior to commercialisation.
