Europe’s largest energy storage system in a building earns T3 Award


The ‘second life’ mega battery of the Johan Cruijff ArenA has won the Eco Award from is one of the largest lifestyle websites with a corresponding magazine in the United Kingdom. Other nominees included sustainability innovations from Tesla and the clothing brand Patagonia.

At the end of June 2018, the Johan Cruijff ArenA put Europe’s largest ‘second life’ megabattery into use in a commercial building. The storage system of 3MW includes second-hand batteries of electric vehicles. The battery achieves a reliable and efficient energy supply and use for (and by) the stadium, its visitors, neighbors and the Dutch energy grid.

The system combines Eaton inverters and the equivalent of 148 Nissan LEAF batteries and shows how energy storage makes a more sustainable energy system possible. In addition, it creates a circular economy for batteries of electric vehicles.

Thanks to the megabatterij, the ArenA is assured of a considerable amount of power, even during a power outage. The stadium will be able to use its own sustainable energy more intelligently and trade in the available storage capacity in the battery, as Amsterdam Energy ArenA BV. As a result, the stadium contributes to a stable Dutch energy grid.

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

The Johan Cruijff ArenA is one of the most sustainable stadiums in the world and leads the way in smart innovations including this unique storage system.
