An Investment in Exergy Power Systems, Inc. through the Society 5.0 Investment Program

Exergy Power Systems, Inc. ("Exergy") has developed the Exergy Battery, a next-generation nickel-hydrogen storage battery that, due to a unique structure that allows for the rapid escape of heat, can be charged and discharged at a rate 20 to 200 times faster than ordinary storage batteries. The Exergy Battery enables the Bunkyo-ku, Tokyo-based firm to offer innovative energy solutions.

In Ireland, instability in the power supply, the result of a sharp increase in the ratio of renewable energy, has become a growing social issue. Exergy supplies these batteries to factories as backup power sources. The firm also provides power supply-and-demand adjustment services in cooperation with power transmission companies. Exergy is building a solid track record in Europe, the world's leader in the use of renewable energy, and expects to expand its services to other regions including Japan.

DBJ invested in Exergy in April 2020 through its Society 5.0 Investment Program. In collaboration with Exergy and its stakeholders, we will play a leading role in promoting the rollout of the Exergy Battery in Japan and overseas, helping to build a social infrastructure that encourages a sustainable energy supply.
