Power Japan Plus and Teikyo University Press Release


Power Japan Plus Inc. (PJP) and Teikyo University (Teikyo), a private university in Tokyo, entered into an agreement on March 29, 2016 to conduct a joint experiment, aiming the creation of a low-carbon campus.

The agreement consists of a new battery named “Ryden” developed and commercialized by PJP to maximize the usage of renewable energy. The preparation of the demonstration experiments is now underway.

As to the solar and wind power generation, there is a supply-demand imbalance, i.e., the weather variability and natural conditions are the problematic for the consistency of power supply. This is the weak point and major obstacle of renewable energy utilization to overcome.

The Ryden battery solves the supply and demand imbalance. As adopted by Miyama city, Fukuoka Prefecture, Teikyo will adopt the Ryden system to compensate the supply variation of its solar panel system.

Meantime, there pursued in renewable energy business circle, “the solution” somehow not to depend on FIT (feed-in tariffs) in order to pursue self-consumption model.

Teikyo’s implementation of the Ryden system will enable self-consumption model and enable other public spaces, private universities and buildings, to pursue self-consumption model.

PJP and Teikyo are seeking for the collaboration with electricity companies and local governments to maximize the usage of renewable energy.


“Ryden” battery is developed by PJP in collaboration with Kyushu University, which does not contain rare metals, rare-earth metals and heavy metals in active materials, i.e., an environment friendly battery.


The carbon used for the active materials of “Ryden” is derived from plants, which just meets the Teikyo’s intention of a low carbon society.


Joint experiment by PJP and Teikyo in Teikyo’s Mega solar system will allow duplication of the Ryden system on other sites. PJP will carry out the demonstration experiment in order to gather big data through the usage of Ryden battery into Teikyo’s Mega solar system and analyze the data for the preparation of the next generation model.


The usage of renewable energy is needed not only in Japan, but also in foreign countries especially developing countries, as smart and micro grid systems are needed in these countries. PJP’s solution naturally enables the appropriate volume of energy for micro and smart grid systems.


As part of social contribution activities, PJP is considering to support Iraq and Syria as both countries are suffering from refugees’ problems. In Iraq, PJP has already begun the implementation of Ryden battery solution with Japan Kurdish Friendship Association.
