In the high desert 25 miles east of Reno, Gooseberry Mine is etched
into the dusty Nevada hills. Until 1990, gold was dug out of the ground
here. Now it's mostly abandoned.
In late March, I stood a few
hundred yards away in a makeshift chemistry lab few people have been
allowed to enter. My tour guide, Adam Kirby, a project manager at Redwood Materials, held up a small capsule containing dark powder.
"Black gold," he said, smiling.
The
substance is known as Cathode Active Material, or CAM, a combination of
metals and minerals that makes up roughly 60% of the value of EV batteries and 15% of the entire price of an electric vehicle.
Oil is the original black gold,
of course. This has powered automobiles for a century. Now, though, EVs
are steadily replacing the internal combustion engine with what Tesla and the rest of the industry hope is a more sustainable alternative.
For
this to really happen, we must recycle the big battery packs inside all
these EVs. Redwood Materials, run by Tesla cofounder JB Straubel, is building North America's biggest battery recycling operation. And CAM is the company's next big bet.
Straubel has been hacking away at this problem for almost a decade.
Since Redwood was founded in 2017, the startup has raised about $2
billion from big investors, including Fidelity, Goldman Sachs, Baillie Gifford, and Amazon.
Today,
Redwood recycles more than 70% of all the lithium-ion batteries in
North America. If you've ever handed old laptops or smartphones to a
recycling center in the US or Canada, it's likely they ended up on a
giant lot in front of Redwood Materials' 300 acre desert campus.
The
company carefully heats these old batteries to just the right
temperature to tease out the base ingredients, which include nickel,
manganese, cobalt, and lithium. By themselves, these metals are valuable
and Redwood has generated hundreds of millions of dollars in revenue by
selling this raw material into the EV supply chain.
The next
step for the company is combining this into CAM, which is a lot more
valuable. Hence the name: new black gold. Instead of digging it up,
Redwood conjures it into being through chemistry at industrial scale.
It's an expensive and technically complex bet for Redwood, Straubel,
and his investors. While driving down from the lab with Kirby, the
project manager, we passed a building under construction that was so
huge it made the nearby earth-moving trucks look like toys. This will
house most of the full-scale CAM production process, featuring a heated
conveyor belt more than 150 feet long.
"Things like Redwood are
multibillion-dollar capex, ambitious projects. You must back people with
experience and gravitas who can execute," said Chris Evdaimon, an
investment manager at Baillie Gifford, who also visited the site
recently.
"To raise equity and debt, while having the trust of governments," he added, "not many people can pull this off."
"Infinitely recyclable"
When I got back down the hill, I was ushered into the main Redwood office building on campus and met Chief Commercial Officer Cal Lankton in the "Nickel" office (next to the "Manganese" and "Lithium" rooms, of course).He recounted how Redwood got started through a surprising
revelation: The ingredients of lithium-ion batteries can be reused over
and over. Unlike the original black gold, these materials don't go up
in smoke or wear out.
"That was the foresight on JB's part," Lankton said. "That's what
differentiates this automotive transformation from previous ones — the
batteries themselves are infinitely recyclable."
Redwood's
processes can now recover about 98% of the critical minerals from
batteries. The problem is that once this stuff has been salvaged, it
must be shipped overseas, mainly to China, where it's refined and
combined into useful products such as CAM.
By the time this
material goes into a new battery cell in a US gigafactory, it has
traveled roughly 50,000 miles from being shipped to Asia and then back
again, according to Baillie Gifford's Evdaimon.
That's massively inefficient. If the US and Europe really want to meet
lofty goals such as having half of cars being electric by 2030, a
homegrown industry is needed. "Redwood Materials is essential for this,"
Evdaimon added....
It's Redwood that we are interested in. The other three, Climeworks,
Solugen and Sila Nanotechnologies may or may not make it but Redwood
seems to be a possible fortune builder....
Which may explain the Go Big or Go Home approach to industrial facilities.
