A senior executive at the power management company Eaton told Reuters that they are in talks with several European soccer stadium heads about using electric vehicle batteries to power their facilities.
“Eaton takes the cells from the batteries of Japanese carmaker Nissan’s returned Leaf electric vehicles and repackages them into new units, a product it calls xStorage, to store power in buildings,” reporter Lefteris Karagiannopoulos wrote.
Senior vice president Craig McDonnell told the news outlet that the soccer stadium community is interested in this type of power, and that his company is in talks with five to six stadiums in Europe.
Last year, Eaton’s energy storage system for the Johan Cruijff Arena in Amsterdam went live. It combined Eaton power conversion units and the equivalent of 148 Nissan Leaf batteries for a total capacity of 3 megawatts. The company says this system can optimally store the energy produced by 4,200 solar panels on the arena’s roof.
Completed in 1996, the Johan Cruijff Arena has a capacity of nearly 55,000 people, is home to the soccer team AFC Ajax, and hosts a variety of concerts.
Eaton, Nissan, BAM, the Mobility House, and the arena collaborated on the energy storage project, which had support from the Amsterdam Climate and Energy Fund and Interreg. The energy storage system provides backup power, reducing the use of diesel generators, and relieves the energy grid by flattening the peaks that occur during concerts, according to Eaton.
“The arena is assured of a considerable amount of power, even during an outage,” Henk van Raan, director of innovation at the Johan Cruijff Arena, said at the time. “As a result, the stadium will contribute to a stable Dutch energy grid.”
Speaking with Reuters, Eaton’s executive said their xStorage solution is 20% cheaper than a new battery.
