Demonstration experiment of the hydrogen fuel cell - making the entire value chain carbon-free
Generating electricity from hydrogen is very energy efficient, and because it does not emit CO2 when used, it will help society become carbon free. Hydrogen offers many other benefits as well. It does not require large-scale infrastructure such as power lines, and in comparison to traditional energy, it can be easily transported and stored. Panasonic is attempting to make breakthroughs in 3 key areas - "production," "storage," and "use" - to realize technologies that enable the use of hydrogen at low costs. For example, to create hydrogen, Panasonic is currently working on photocatalytic technology that splits water when sunlight hits the catalytic agent and using highly efficient non-metal electrodes. With respect to storage, Panasonic is conducting research on high-density storage technologies.
Hideo Ohara, General Manager of Hydrogen And Energy Research Laboratory, Advanced Research Division of Panasonic stated, "The biggest challenge when it comes to building a hydrogen society is costs. And the entire value chain must be carbon free. Eventually, we hope that people will be able to create and store hydrogen at home using photocatalytic technology.

Since November 2016, 3 units of Panasonic's prototype hydrogen fuel cell have been installed in the "Yume Solar Kan Yamanashi" in Komekurayama, Yamanashi Prefecture. Panasonic is conducting its demonstration experiment in cooperation with the prefectural government. Yamanashi, home of the World Heritage site, Mt. Fuji, has a high awareness for preventing and reducing disasters, and it has also been one of the earliest prefectures to adopt mega solar. Using the energy management system, this facility sorts 10,000kW of energy created from solar power generation into "stable" and "unstable" energy. Stable energy is then supplied to the grid, and the remaining unstable energy will be injected into the large-scale water electrolysis device to electrolyze tap water. It is estimated that annually 450,000Nm3 (normal cubic meter) of hydrogen will be created. And experiments are being conducted to use this hydrogen to generate electricity with the 3 hydrogen fuel cells, which will be cooperatively controlled to respond to the changes in demand.

Panasonic is giving life to multitudes of devices that will support the hydrogen society of the future
When hydrogen society becomes a reality, cities will need a wide range of hydrogen infrastructure, for example, hydrogen tanks for storing hydrogen, hydrogen stations that supply hydrogen to fuel cell vehicles, and at homes, hydrogen fuel cells. It is anticipated that such a hydrogen society will be the new norm by 2030, so Panasonic is already developing various devices necessary to support infrastructure.
Panasonic is supporting the urban smart city, the "Tsunashima Sustainable Smart Town," the launch of which is planned around 2018. This town will also have a hydrogen station, so trials to supply energy to fuel cell vehicles have begun. What Panasonic believes would be ideal is for hydrogen energy to be able to accommodate people's needs and to support people's lives safely. With an eye on the future, Panasonic will continue to have a wide vision and provide unique solutions all around the world.
