JAPAN – Power cuts in big cities nowadays constitute a primary concern. In order to find a lasting solution it is necessary to explore new energy sources. That’s why the DMG Mori Seiki in Tokyo has developed a new system of energy storage.

Three Cellcube units have appeared on the roof of the DMG Mori Seiki building in the Japanese capital. These units are designed to collect solar energy and store it for a further use. This initiative aims to reduce the recurring power cuts currently encountered in the city.

What are the particularities of these three Cellcube units installed by DMG Mori Seiki? And what technology do they use to operate?

The Characteristics of the Three Cellcube Units

The Cellcube units which have been installed by DMG Mori Seiki are FB 10-100 ones. The manufacture of the equipment is the work of the German company GILDEMEISTER, a subsidiary of the Japanese company.

Cellcubes are energy solutions that store energy and operate with the following principles:
• They capture solar energy and convert it into electricity through a photovoltaic system which is located on the roof of the newly constructed DMG MORI SEIKI building which opened during July 2014.
• The transformation of the energy supply is possible through a turbine with a capacity of 10 KW which rotates vertically.

It should be noted that this power will be useful for damping peak energy consumption and allow the company´s electronic equipment to operate even when there is a power cut.

The Technology used in the Cellcube

The Cellcubes use redox flow vanadium technology allowing themto capture solar energy. With this technology, the storage capacity reached 300 KWH. Then it is worth mentioning that this technology intervenes in case of fluctuating electricity levels.

This option implemented by DMG Mori Seiki is a solution which can also be used in case of energy failure in order not to slow the company activities.
