The 10-Second Version (AI Summary)
What happened: Houston startup Element3 is extracting lithium from the salty wastewater produced by oil drilling in West Texas.
Why it matters: Most lithium processing happens in China, and this could build a domestic supply for EV batteries.
What to do: If you sell EVs, watch how domestic battery supply develops as startups like Element3 scale.
AI-generated summary, reviewed by the ASOTU team.
We’ve heard coffee grounds are good for the garden, which means every dealership service lounge is quietly producing a gold mine. A startup in Texas took that same instinct and pointed it at something far less appetizing. The water that comes up with Permian Basin oil is so salty it ruins plants, and nobody quite knows where to put it. Houston-based Element3 sees it as one of America’s great untapped resources. It was the story on today’s episode of ASOTU we never saw coming.
What is Element3 pulling out of oil wastewater?
Lithium, along with magnesium and strontium. Permian Basin drilling brings up about 26 million barrels of water a day, roughly what all of New York City uses daily. Oil production runs around 6 million barrels a day. The water is ancient seawater, five times saltier than today’s oceans.
More than four barrels of water come up for every barrel of oil.
How does Element3 get lithium out of the brine?
Founded in 2021, Element3 is commercializing research from the Department of Energy’s Oak Ridge National Laboratory on filtering lithium from that brine. The company also has a built-in advantage. Oil companies have already built massive infrastructure to move this water, so Element3 can tap into a system someone else paid for.
CEO Hood Whitson calls it “a wonderful circular economy, waste-to-value story.”
Why does a domestic lithium source matter for EVs?
Most lithium processing happens in China, and the U.S. imported more than $16 billion worth of lithium-ion batteries from China in 2024. Element3 is still early. It has raised a little over $20 million and has 15 employees, per PitchBook, and it is working to scale production across Texas.
A homegrown lithium supply would change where the raw materials in EV batteries come from.
What can dealers take from Element3’s waste-to-value story?
When lithium prices were climbing a few years ago, we figured people would find new ways to harvest it, probably through some kind of recycling. Oil-field brine wasn’t on our list. That’s American ingenuity and entrepreneurship at work: someone spots value in a disposal problem, researches it and gets the funding to chase it.
Someone looked at an industry’s wastewater and saw one of the country’s largest untapped resources.
If you sell EVs, keep an eye on domestic battery supply as companies like Element3 scale up. Where the lithium in tomorrow’s batteries comes from could eventually shape the cost and availability of the EVs on your lot.
