Along with the massive recent manufacturing investments in electric vehicle (EV) technology and talks of a greener, decarbonized future, there are some not-so-green problems.
In its latest New Energy Finance report, Bloomberg News predicts there will be some 730 million EVs on the road by 2040. The year before, Bloomberg predicted half of all U.S. vehicle sales would be battery electric by 2030.
In Canada, too, there’s talk of a big economic boost with the transition to EVs — including 250,000 jobs and $48 billion a year added to the nation’s economy through the creation of a domestic supply chain.
Governments have already invested tens of billions into two EV battery manufacturing plants in southwestern Ontario. However, they come with the environmental dilemma of what to do with the millions of EV batteries when they reach the end of their life.
“The rules are non-existent,” said Mark Winfield, a professor at York University in Toronto and co-chair of the school’s Sustainable Energy Initiative. "There is nothing as we talk to agencies on both sides of the border, the federal, provincial, state levels.
“In the case of Ontario, the answer was actually that we have no intention of doing anything about this.”
Actually it seems to be one of the more talked about aspects, right after the local environmental costs of mining in some poorer countries, dispite being one of the easiest to solve.
You drop EV batteries into a dielectric bath industrial crusher and get thousands of dollars of absurdly high grade lithium-cobalt ore out of it. While there are hard questions that industry has not put much public press into answering, especially when it comes to environmental concerns, in this case the reason is that it’s actually pretty trivial to deal with.
Given that lead acid batteries have a ninety seven percent capture rate dispite only being worth a few dozen dollars at most, we can expect higher rates with the far more valuable EV batteries. Lithium is infinitely recyclable after all, and for all the failings of the free market when it comes to keeping personal electronic’s batteries out of landfills I doubt you need much overarching regulation to get people to take the five to seven thousand dollar payout from recycling in this case.
The reason we don’t see high recycling rates currently in the space is that despite worries that the batteries would degrade to the point of uselessness after a few short years, the vast majority of EVs are still on the road and looking to have a longer average lifespan than gasoline vehicles. On top of that there are a lot of applications which want the reuse them and there is a reason that reduce, reuse, recycle are in that order.
And of course, any talk of the environmental impacts of EVs has to be caveated by the fact that 60 to 70 percent of an EVs emissions cost comes from the power grid itself, which is rapidly changing as renewables push out more expensive coal and natural gas. Of the remainder, most of it is in mining the raw material for the battery itself, which as mentioned only has to be paid once before it is recycled for quite potentially forever.
Unlike a gas car which on average produces more than twice their weight in co2 every single year it’s on the road, an EVs emissions break even after only two to four years, after which that car and its future descendants will continue to just go mile after mile without contributing to gobal environmental collapse.
While things like more of Vancouver’s trolleybus network would obviously be best, given the population densities involved as well as the housing shortage we’re not going to be able to replace all cars in North America on the timelines the laws of physics demand we meet, and it’s important to keep that in mind when discussing it.
Well said!
Whenever I read something like that, I can’t help thinking of my son, who has paid zero attention to any advance since first hearing about the EV-1 or some shill with an agenda.
Personally, I’d love to have a business taking batteries no longer fit for purpose in cars and building off-grid wind and solar systems. That’ll never happen, though, because at 67 I’m too old to ever see used batteries in enough volume to justify trying it.
My personal opinion is that the need for large scale recycling is still decades away. If a vehicle’s battery pack isn’t completely physically damaged, it is more likely to end it’s life in use for stationary power or split into smaller packs for short range, occasional use vehicles, like boats, ATVs, small farm and yard equipment, and, of course, golf carts and “city cars”.
They don’t use Lithium Cobalt Oxide anymore.
Not exclusively, but unfortunately in North America a lot of marketing has been put into maximum range, and so lithium iron phosphate is still in the minority of market volume becuse of the thirty percent volume penalty. Things are better in China with the larger focus on budget options, and they even have a sodium vehicle now on the market, but to my knowledge lithium cobalt still makes up the majority of North American EVs, in volume sold if not in models.
