Energy Storage system Johan Cruijff ArenA wins Business Green Technology Award

The largest European energy storage system using second-life and new electric vehicle batteries in a commercial building has won the 2018 BusinessGreen Technology Award in the Future City Technology of the Year category.

The award-winning project is the result of collaboration between Eaton, Nissan, BAM, The Mobility House and the Johan Cruijff ArenA, supported by the Amsterdam Climate and Energy Fund (AKEF) and Interreg.

The 3 megawatt storage system in the largest multi-purpose stadium in the Netherlands provides a more reliable and efficient energy supply and usage for the stadium, its visitors, neighbors and the Dutch energy grid. Combining Eaton power conversion units and the equivalent of 148 Nissan LEAF batteries, the energy storage system not only enables a more sustainable energy system, it also creates a circular economy for electric vehicle batteries.

The energy storage system plays an important role in balancing supply and demand of energy in the Johan Cruijff ArenA. The storage system has a total capacity of 3 megawatt, enough to power several thousand households. This capacity also means that the energy produced by the 4,200 solar panels on the roof of the ArenA can also be stored and used optimally. The energy storage system will provide back-up power, reducing the use of diesel generators, and provide relief to the energy grid by flattening the peaks that occur during concerts.

“Sustainability is at the heart of our strategy. The Johan Cruijff ArenA is one of the most sustainable stadiums in the world and leads the way in introducing smart innovations like this unique energy storage system.” says Henk van Raan, director of innovation at the Johan Cruijff ArenA. “We are extremely honored to see that this innovative project has been officially recognized.”

“What we have developed at the Johan Cruijff ArenA is a clear demonstration of what the future could look like for stadiums and cities across Europe.” says Fabrice Roudet, Head of Energy Storage Business Unit, Electrical EMEA at Eaton. “Applying these ideas, technologies and services into other industries could also have a huge impact on being able to provide sustainable, resilient energy for everyone.”

“With the energy storage system in the Johan Cruijff ArenA, we provide another opportunity to store renewable energies. Thereby the project brings us one step closer to realizing our vision of an emission-free future.” says Thomas Raffeiner, CEO and founder of The Mobility House. “Our technology already enables us to commercialize more than 2000 vehicle batteries on the energy markets in various projects as stationary storage systems. Consequently, technically it is already possible to intelligently integrate electric vehicles into the grid to provide grid services. It will bring the energy and automotive worlds even closer together and pave the way for innovative and sustainable business models.”
