According to Reuters, US company Eaton, which uses second-hand Nissan electric vehicle (EV) batteries to power buildings, is in talks with up to six European football stadiums to help power their facilities.
There is a growing concern as to what to do with the used EV batteries as their use expands with that of electric cars, which accounted for 1.5% of the 86 million cars sold globally last year, according to researchers JATO Dynamics.
Eaton takes the cells from the batteries of Japanese car maker Nissan’s returned Leaf EVs and repackages them into new units, a product it calls xStorage, to store power in buildings, both industrial and residential.
It has already installed, what they call, “second-life batteries” at the Johan Cruyff Arena in Amsterdam, home of the Ajax football team, among other buildings. Its latest project was in Oslo’s Bislett athletics stadium in Norway, which is partly powered by solar panels.
Eaton’s senior-vice president Craig McDonnell said: “The football stadium community is interested. From significant ones, (we are talking) with 5-6 stadiums in Europe.”
With the exception of Tesla which it sees as a competitor in the storage business, the firm is also talking with other automakers to expand its offering. McDonnell declined to give names.
Eaton says its xStorage solution is 20% cheaper than a new battery and every Nissan Leaf car can produce four such units.
It is among the large-scale commercial ones in the developing market, with other projects run by German automaker BMW which supplies second-hand batteries from its i3 electric vehicles to store wind-farm produced electricity.
