PowerX, a Japanese technology company developing a project to ship energy from offshore wind farms in batteries, has started to generate investor and buyer interest.

The concept was launched earlier this year by Japanese technology entrepreneur Masahiro Ito.

He is best known for developing digital body measurement technology, now acquired by ZOZO Corp, for use in online clothes retailing.

Ito's latest idea is to shuttle offshore energy between wind farms and the shoreside in containerised modular batteries on purpose-built containerships.
