Oslo - US industrial conglomerate Eaton, which uses second-hand Nissan electric vehicle batteries to power buildings, is in talks with up to six European football stadiums to help power their facilities, according to a senior executive.
Eaton, which makes hydraulics, truck transmissions and other industrial products, says the market is niche but expects it to grow up to 20 times between now and 2022.
In Europe, Middle East, and Africa, Eaton estimates the potential market value to be $2.3 billion (R32.8bn) by 2025.
What to do with the used batteries of electric vehicles is becoming a growing concern 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 Nissan's returned Leaf electric vehicles and repackages them into new units, a product it calls xStorage, to store power in buildings, both industrial and residential.
