Sumitomo and CMI Energy signed an MoU in June 2017, becoming strategic partners in the international marketing of Sumitomo’s redox battery, in particular in Europe and the MENA region.

MiRiS is under construction at the headquarters of CMI, in Seraing, Belgium.

Sumitomo Electric Industries has been a pioneer in the vanadium redox field for decades, with what is thought to be the most operating experience with this technology, and an installed base of around 104 MWh.

Via the June MoU, Sumitomo hopes to to expand its references in Europe and MENA with a European partner capable of installing the redox battery and acting as an EPC integrator.

CMI Energy says it will incorporate Sumitomo’s vanadium redox technology in its product line-up and promote it as a “differentiating factor in the booming energy storage market.”

MiRiS will also include lithium-ion batteries and will be used to investigate various use cases, such as electricity self- consumption, solar photovoltaic time shift and resale of the excess electricity, as well as provision of ancillary services, eg primary reserve and voltage stability.

CMI plans to scale up the facility in the future, with Sumitomo playing an important role.
