Reused electric car batteries to power the Johan Cruijff ArenA
Electric solutions are progressively taking the stage in different industrial and commercial sectors, from cars to heavy equipment applications. Naturally, the transition to hybrid and fully electric solutions occurs with different timing and at different paces. This depends on the suitability of such solutions to the needs of the different fields of application. In this terms, what is going on at the Johan Cruijff ArenA in Amsterdam represents a big step forward.
At the back of the arena, there is a 3-megawatt storage unit built from reused electric car batteries. Economic resources are mainly provided by Amsterdam Climate and Energy Fund (AKEF) and Interreg., but the project represents the result of a partnership that involves Nissan, Eaton and other companies. These include BAM, The Mobility House and the Johan Cruijff ArenA.
Broad energy coverage
The power supply agreement has been defined over the past two years (allegedly 2016). As leading partners, Nissan and Eaton hold a 10-year deal with Amsterdam ArenA to provide back-up power to the stadium. The 3-megawatt storage system supplies all the energy necessary for the stadium and for the visitors. It is also connected to the Dutch energy grid and can provide electricity to the neighbors of the stadium of Ajax football team. In fact, the energy supply can easily power thousands of families.
Its functions include balancing supply and demand of energy in both the Johan Cruijff ArenA and the grid. Moreover, in case of power outages, it can still provide the energy supply for the arena to keep working. In order to work, the storage system relies on power conversion units that Eaton provides, and the equivalent of 148 Nissan LEAF batteries. In terms of power output, it means having 3MW and 2.8MW per hour of energy available. Additionally, thanks to its dimensions, the system can store the energy coming from the 4,200 solar panels installed on the roof.
