"Last month, a small warehouse in the English city of Nottingham received the
crucial final components for a project that leverages the power of used EV
batteries to create a new kind of circular economy.
Inside, city authorities have installed 40 two-way electric vehicle chargers
that are connected to solar panels and a pioneering battery energy storage
system, which will together power a number of on-site facilities and a fleet of
200 municipal vehicles while simultaneously helping to decarbonize the UK’s
electrical grid.
Each day Nottingham will send a combination of solar-generated energy — and
whatever is left in the vehicles after the day’s use — from its storage devices
into the national grid. The so-called “vehicle to grid” chargers deliver this
energy just when it’s needed most, during peak evening demand, when people are
home cooking, using hot water or watching TV. Later, the same chargers pull
energy from the grid to recharge the vehicles in the wee hours of the night,
when folks are sleeping and electricity is cheaper and plentiful.
“We are trying to create a virtual power station,” says Steve Cornes,
Nottingham City Council’s Technical Lead. “The solar power and battery storage
will help us operate independently and outside of peak times, making our system
more resilient and reducing stress on the national grid. We could even make a
profit.”
What makes the project truly circular is the battery technology itself. Funded
by the European Union’s Interreg North-West Europe Programme, the energy
storage system, E-STOR, is made out of used EV batteries by the British company
Connected Energy.
After around a decade, an EV battery no longer provides sufficient performance
for car journeys. However, they still can retain up to 80 percent of their
original capacity, and with this great remaining power comes great
reusability."
I see what they did there.
