Toshiba Corporation’s energy supply system has been chosen by Tohoku Electric Power Co. to support a two-year power management study in which it will evaluate hydrogen (H2) in overcoming fluctuations from renewable sources.

Under the terms of the deal, of which financial details were not disclosed, Tohoku Electric will use Toshiba’s H2OneTM H2-based autonomous energy supply system in its study.

The independent instrument features a highly efficient cogeneration system based on Toshiba’s unique H2 energy management system (EMS) and uses renewable energy and H2 to stably supply electricity. It consists of a solar power generation system, storage battery, H2 production equipment, H2 storage alloy tank and a pure H2 fuel cell.

Over the course of the two-year project, Tohoku Electric will monitor the viability of the H2 power storage system as a solution for offsetting power output fluctuations caused by an expansion of renewables.

“Introducing renewables and hydrogen into that mix will help to achieve the crucial goal of a low-carbon future”

Hiroyuki Ota, General Manager of Toshiba’s Energy Systems and Solutions Company, explained, “A best mix of power sources will contribute to energy security and sustainability, and introducing renewables and H2 into that mix will help to achieve the crucial goal of a low-carbon future.”

“H2 offers an innovative approach to emission-free clean energy and we want to promote wide acceptance of H2 solutions,” he added.

In October, Tohoku and Toshiba joined forces with Iwatani Corporation in a government-supported scheme that is investigating the configuration and specification of a H2 energy system which encompasses the world’s largest H2 production system.
