Amsterdam Arena is one of the Europe’s big stadiums: with 54.000 seats, it has been the stage of big events and recently it has gone through a series of renovations to make it more energy-efficient, before it takes the official name of Johan Cruyff Arena. Among these measures, it has been set a system consisting in 280 used batteries of Nissan Leaf – Yes, from the same Nissan Leaf that runs by the streets – as energy support. That makes diesel generators not necessary anymore in this football temple and, what makes it most interesting, the stadium also works as an electricity distributor when this stored energy is not being used.
And yes. You have read it right; the 280 batteries they use are second-hand.
That is because electric cars has every time more autonomy, for instance; with just one complete charge, Renault Zoe can run about 400 kilometres, when just some years ago, the autonomy was quite more limited. And not only the batteries last longer on the highroad, their life cycle as such can be extended, even after doing it’s job in the electric cars, it can be used as a household electric energy storage. Or for a stadium!
In fact, a part from the batteries for the Amsterdam Arena Stadium, Eaton and Nissan has developed the household battery system xStorage, which stores energy from renewable sources, as the solar energy, in order to use it at home or to charge the car.
Obviously the manufacturers know the electric car it’s a much bigger change than a simple step to another fuel. It also means a deep revolution in our life and the way we consume electricity. Just a sample: Can you imagine being able to have electricity during a general neighbourhood blackout thanks to your car battery? Even more, can you imagine to sell this stored energy online? This last one is called V2G (Vehicle to Grid) and Nissan and Endesa are already developing it for a couple of years now.
On average a civilian car stays parked the 90% of its time. And from this 90%, most of the time does it in a private parking lot. And if the Amsterdam Arena Stadium has 280 batteries for 54.000 people, What cannot an electric car battery do for a house? Let’s see it that way: There is less energy demand during the night; therefore the Kw/h price is lower. It’s the best moment to do a slow charge to the car, as, on average, it needs 8 hours to charge up. But if we don’t take the car in the morning, we can still keep it plugged in and we can use the charge during the pick hours when the energy demand is higher, in order to save money. Ah!, Also, remember there are special fares to charge electric cars. Even more, if we don’t use the charge we could sell the electricity on the network.
We have to take into account that when the time comes to use the car, it’s much cheaper to start up an electric car that one that runs on conventional fuel. Let’s make the comparison between Volkswagen Golf and its electric brother: The first one uses 4L every 100 Km on the open road, whereas the e-Golf has a consumption of 12,7kWh/100kms. If we pay attention to this tool, we can see the cost per km of the electric version is risible, whereas with the Golf powered by gas we can notice the fuel price.
If a stadium uses the electric car batteries to stock up, imagine how it might be to have a whole electric car!
