World : CMI opens industrial energy storage pilot plant MiRIS

CMI Energy, part of Cockerill Maintenance & Ingénierie (CMI) Group, has opened an industrial energy storage facility called the Micro Réseau Intégré Seraing (MiRIS) in Seraing, Belgium.

Located at the CMI Group’s international headquarters, MiRIS features renewable, as well as energy storage systems, and is integrated with a microgrid.

The renewable portion of MiRIS includes a 2MWp, 1.75GWh per year, the photovoltaic system with 6,500 rooftop and carport panels, while the 4.2MWh energy storage part comprises a lithium-ion battery system and two different flow battery systems.

CMI Energy president Jean-Michel Gheeraerdts said: “We now have ways to use green energy sources that eradicate their major flaw – intermittent production.

“Energy storage and management can be applied in a number of fields as an alternative to diesel generators for unconnected regions, as a way of deferring investment in parts of the network, as a means of optimising existing photovoltaic or wind systems, and as an enabler of participation in the primary or secondary reserve markets.”

The company noted that its new energy storage pilot plant has been designed to demonstrate an advanced integration of intermittent renewable energy resources with battery-based energy storage to produce a fully dispatchable renewable energy resource.

Additionally, MiRIS will focus on the interoperability of renewables and different energy storage technologies for a variety of user energy profiles.

MiRIS will also allow assessment of microgrid ‘islanding’ operations, potential grid ancillary service opportunities, and the influence of user demand response.

Established in 1817, CMI Energy is a global supplier of heat recovery steam generators (HRSGs), industrial boilers and steam generators for concentrated solar power with thermal storage.
