The Department of Energy just took a first step toward launching new lithium-ion battery recycling programs in the US. It issued a Request for Information (RFI) yesterday to ask for public input on how to spend $335 million in federal investments for battery recycling that was included in the Bipartisan Infrastructure Law passed last year.

Lithium-ion batteries used to power electric vehicles and store renewable electricity are a major building block for a clean energy economy. Recycling could ease the impending squeeze on materials needed to meet rapidly rising demand for those technologies — especially as the Biden administration tries to keep the US on track to meet pollution-cutting goals it’s agreed to under the Paris climate accord.

A major building block for a clean energy economy

“Battery recycling doesn’t just remove harmful waste from our environment; it also strengthens domestic manufacturing by placing used materials back into the supply chain,” US Secretary of Energy Jennifer Granholm said in an August 29th press release.

All in all, the Bipartisan Infrastructure Bill invests over $7 billion over five years to build up a domestic battery supply chain. That includes $335 million for lithium-ion battery recycling programs. The Department of Energy (DOE) issued the Request for Information in order to help guide its implementation of those recycling programs and plans to take comments from the public until October 14th.

The programs are supposed to improve the process of collecting batteries at the end of their lives and harvesting valuable materials from them. The programs also aim to minimize environmental risks from tossing out and rehashing used batteries while also making battery cycling more popular and developing a new workforce for the recycling industry.

The funding will also go toward finding useful second lives for old electric vehicle batteries. An EV battery might be replaced once it’s lost about 20 percent of its capacity. But that means it could have up to 80 percent of its capacity left for other uses. The battery might be paired with solar panels, for instance, to hold excess energy soaked up during the day so that the clean electricity is available at night. Some car companies, including Nissan, are researching how to reuse EV batteries to store renewable energy for power grids.

Finding useful second lives for old electric vehicle batteries

Policymakers, meanwhile, are scrambling to figure out how the nation is going to have enough batteries on hand to reach its climate goals. To slash greenhouse gas emissions, Biden wants the power sector to run entirely on carbon-free electricity by 2035 — which will be virtually impossible without a lot more energy storage from batteries. Biden also issued an executive order last year calling for half of all new vehicle sales in the US to be hybrid or electric vehicles by the end of the decade. And California, one of the world’s biggest markets for cars, laid out new rules last week to phase out gas-guzzling cars in favor of plug-in hybrid and battery-electric vehicles by 2035.

Similar shifts need to happen across the world to avoid the worst effects of climate change, like dramatically more severe storms, droughts, and heatwaves. Greenhouse gas pollution needs to drop to net zero by around 2050 to reach goals set out in the Paris climate agreement aimed at ensuring a more livable future. But reaching those goals would require six times more critical minerals in 2040 than were produced in 2021, according to an analysis by the International Energy Agency.

How to satiate the growing hunger for battery materials without tearing up the environment and harming communities

That’s already triggered another conundrum — how to satiate the growing hunger for battery materials without tearing up the environment and harming communities near mines. Mining for things used in batteries like nickel and cobalt has historically been concentrated in a handful of regions, making markets for those materials vulnerable to labor and environmental abuses and supply chain shocks.

To reduce US dependence on minerals mined in those regions, the DOE released a “national blueprint” for manufacturing lithium-ion batteries last year. And the Biden administration invoked the Defense Production Act in March to ramp up mining and processing materials within the nation’s borders. But that push for domestic mining has environmental groups and Native American tribes worried about what damage it might cause at home.

If the US prioritizes recycling batteries, rather than relying so heavily on extracting brand new materials, it could help shrink many of those problems.

Missing classic Mario?

One fan, who goes by the name Metroid Mike 64 on Twitter, just built a full-on 2D Mario game inside Super Mario Maker 2 complete with 40 levels and eight worlds.

Looking at the gameplay shared on Twitter is enough to make me want to break out my SNES, or at least buy Super Mario Maker 2 so I can play this epic retro revamp.

Idle equipment, absent workers, deserted villages, an empty swimming pool. VinFast is Vietnam’s answer to Tesla, with the goal of making 1 million EVs in the next 5-6 years to sell to customers US, Canada and Europe. With these lofty goals, the company invited a bunch of social media influencers, as well as some auto journalists, on a “a four-day, multicity extravaganza” that seemed more weird than convincing, according to Bloomberg.

Today, 39 years ago, the world didn’t end.

And it’s thanks to one man: Stanislav Petrov, a USSR military officer who, on September 26th, 1983, took the decision not to launch a retaliatory nuclear attack against the US. Petrov correctly guessed that satellite readings showing inbound nukes were faulty, and so likely saved the world from nuclear war. As journalist Tom Chivers put it on Twitter, “Happy Stanislav Petrov Day to those who celebrate!” Read more about Petrov’s life here.

Deepfakes were made for Disney.

You might have seen the news this weekend that the voice of James Earl Jones is being cloned using AI so his performance as Darth Vader in Star Wars can live on forever.

Reading the story, it struck me how perfect deepfakes are for Disney — a company that profits from original characters, fans' nostalgia, and an uncanny ability to twist copyright law to its liking. And now, with deepfakes, Disney’s most iconic performances will live on forever, ensuring the magic never dies.
