Sponsoring and Speaking at the Nikkei CNBC Seminar

Green Battery Inc. (head office: Minato-ku, Tokyo; Representative Director: Kotaro Okada) will take part as a sponsor in “Energy Independence and New Trends in Investment,” a seminar hosted by Nikkei CNBC, where Yusuke Kato will speak.

In our session we will explain output curtailment, which has become an issue as renewable energy expands, and the growing role of grid-scale battery storage as a source of flexibility.

Part 2 features a special lecture by Taizo Sugimura, former member of the House of Representatives, entrepreneur and investor. The seminar is an opportunity to consider what steps are needed for Japan’s energy independence, and we encourage anyone interested to join.
