The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

Texas ride-hailing app grows Houston fleet with EV additions

rolling out

Your next Alto ride might be electric. The Dallas-based car service has rolled out electric vehicles in Houston.

Alto, founded in Dallas in 2018 and launched in Houston in 2020, elevates ridesharing with its own fleet of company-owned, clearly branded SUVs driven by its staff of drivers. The company previously announced its plans to evolve its fleet into being completely electric, and the first EVs have hit the road, according to a company email.

"Our EV additions to the Houston fleet mark an important moment in our commitment to significantly reduce Alto's environmental impact," reads the email sent on September 5.

The new cars offer similar features to its existing fleet, including legroom, phone chargers, water bottles for riders, and more. Plus, the new cars — Kia EV9 — boast a quieter ride.

Alto has consistently grown in its Texas markets — which include Houston and Dallas — over the years, including expanding into Houston's suburbs.

Will Coleman, CEO of Alto, previously wrote in a guest column for InnovationMap that his priorities for starting the company included safety — but also sustainability. For years, Alto has been expressing interest in introducing EVs, with plans of having a completely electric fleet.

"This EV vision is one example of how a rideshare company can build a better and more accountable industry, and these steps also give Houstonians a more responsible and sustainable transportation solution," Coleman writes.

Tesla sales fall for second straight quarter despite price cuts, but decline not as bad as expected

by the numbers

Tesla's global sales fell for the second straight quarter despite price cuts and low-interest financing offers, another sign of weakening demand for the company's products and electric vehicles overall.

The Austin, Texas, company said Tuesday that it sold 443,956 vehicles from April through June, down 4.8 percent from 466,140 sold the same period a year ago. But the sales were better than the 436,000 that analysts had expected.

The better-than-expected deliveries pushed Tesla's stock up 10 percent Tuesday. The stock is down about 7 percent so far this year, but it has nearly erased larger losses from prior months. Tesla shares had been down more than 40 percent earlier in the year, but are up more than 60 percent since hitting a 52-week low in April.

Demand for EVs worldwide is slowing, but they're still growing for most automakers. Tesla, with an aging model lineup and relatively high average selling prices, has struggled more than other manufacturers. Still it retained the title of the world's top-selling electric vehicle maker.

For the first half of the year, Tesla sold 830,766 electric vehicles worldwide, handily beating China's BYD, which sold 726,153 EVs.

Tesla also sold over 33,000 more vehicles during the second quarter than it produced, which should reduce the company's inventory on hand at its stores.

Tesla's sales decline comes as competition is increasing from legacy and startup automakers, which are trying to nibble away at the company's market share. Most other automakers will report U.S. sales figures later Tuesday.

Tesla gave no explanation for the sales decline, which is a harbinger of what to expect when it posts second-quarter earnings on July 23.

Nearly all of Tesla’s sales came from the smaller and less-expensive Models 3 and Y, with the company selling only 21,551 of its more expensive models that include X and S, as well as the new Cybertruck.

The sales decline came despite Tesla knocking $2,000 off the prices of three of its five models in the United States in April. The company cut the prices of the Model Y, Tesla’s most popular model and the top-selling electric vehicle in the U.S., and also of the Models X and S.

The April cuts reduced the starting price for a Model Y to $42,990 and to $72,990 for a Model S and $77,990 for a Model X. Last week, Tesla lopped $2,340 off the $38,990 base price of some newly revamped Model 3s that were in the inventory shipped to its stores.

In addition, Tesla in May offered 0.99 percent financing for up to six years on the Model Y. In June, it offered interest as low as 1.99 percent for three years on the rear-wheel-drive Model 3. Typical new-vehicle interest rates average just over 7 percent, according to Edmunds.com.

Also during the quarter, Tesla knocked roughly a third off the price of its “Full Self Driving” system — which can’t drive itself and so drivers must remain alert and be ready to intervene — to $8,000 from $12,000, according to the company website.

Jessica Caldwell, head of insights for Edmunds.com, said Tesla is having trouble in a market where most early adopters already have EVs, and mainstream buyers are more skeptical that electric cars can meet their needs.

Tesla's “haphazard” price cuts don't work as well as they once did because consumers now expect them, she said. “We’ve seen the automaker exhaust its bag of tricks by lowering prices and increasing incentives to spur demand without much success in the U.S. market,” Caldwell said.

Also, Tesla's aging model lineup doesn’t look much different than it did years ago she said. And with price cuts, used Tesla prices tumbled. Anyone wanting a Tesla can get a far better deal buying a used one, Caldwell said.

Caldwell doesn’t see any big catalyst this year that would boost Tesla sales unless gasoline prices spike, and she said Musk's shift to the right since taking over Twitter has hurt the brand's image.

Wedbush analyst Dan Ives wrote in a note to investors Tuesday that second-quarter sales were a “huge comeback performance” for Tesla. “In a nutshell, the worst is in the rearview mirror for Tesla,” he wrote. The company, he wrote, cut 10 percent to 15 percent of its workforce to reduce costs and preserve profitability. “It appears better days are now ahead as the growth story returns,” Ives wrote.

In its letter to investors in January, Tesla predicted “notably lower” sales growth this year. The letter said Tesla is between two big growth waves, one from global expansion of the Models 3 and Y, and a second coming from the Model 2, a new, smaller and less expensive vehicle with an unknown release date.

Tesla is scheduled to unveil a purpose built robotaxi at an event on Aug. 8.

Sysco introduces new fleet of electric trucks at Houston operations

ev moves

Houston-based food distributor Sysco is helping fuel the future of electric vehicles.

Sysco recently took delivery of 10 heavy-duty, electric-powered trucks for its Houston operations. With this delivery, Sysco now operates nearly 120 electric vehicles (EVs) around the world.

In 2023, Sysco unveiled its first EV hub, which is in Riverside, California. The hub will eventually feature:

40 electric-powered refrigerated trailers
40 electric-powered semi-trucks
40 charging stations

The hub also will include 4 megawatt-hours of battery storage and 1.4 additional megawatts of solar power generation.

Aside from Houston and Riverside, Sysco uses EVs in Baltimore; Boston; Baltimore; Denver; Long Island, New York; Los Angeles; and Fremont, California. Its EV fleet extends to Canada, Sweden, and the United Kingdom.

Sysco announced in 2021 that it planned to operate nearly 800 electric-powered semi-trucks by 2026. Houston Freightliner is a partner in this initiative.

In all, Sysco aims to electrify 35 percent of its U.S. tractor fleet.

Around the world, EVs are contributing to Sysco’s goal of reducing direct emissions by 27.5 percent by 2030.

“We are proud of our progress to scale our electric truck fleet and continue our journey to meet our climate goal,” Neil Russell, chief administrative officer at Sysco, says in a news release. “This work is important to many of our customers who have also set goals to reduce emissions.”

ExxonMobil revs up EV pilot in Permian Basin

seeing green

ExxonMobil has upgraded its Permian Basin fleet of trucks with sustainability in mind.

The Houston-headquartered company announced a new pilot program last week, rolling out 10 new all-electric pickup trucks at its Cowboy Central Delivery Point in southeast New Mexico. It's the first time the company has used EVs in any of its upstream sites, including the Permian Basin.

“We expect these EV trucks will require less maintenance, which will help reduce cost, while also contributing to our plan to achieve net zero Scope 1 and 2 emissions in our Permian operations by 2030," Kartik Garg, ExxonMobil's New Mexico production manager, says in a news release.

ExxonMobil has already deployed EV trucks at its facilities in Baytown, Beaumont, and Baton Rouge, but the Permian Basin, which accounts for about half of ExxonMobil's total U.S. oil production, is a larger site. The company reports that "a typical vehicle there can log 30,000 miles a year."

The EV rollout comes after the company announced last year that it plans to be a major supplier of lithium for EV battery technology.

At the end of last year, ExxonMobil increased its financial commitment to implementing more sustainable solutions. The company reported that it is pursuing more than $20 billion of lower-emissions opportunities through 2027.

A new list from EV Charger Reviews puts Texas in the No. 2 position among the worst states for owning an EV. Photo via Getty Images

Texas ranked as among the worst states for EV drivers

yikes

You’d think that producing tens of thousands of Teslas might help drive up Texas’ standing among the best states for owning an electric vehicle. To the contrary, Texas ranks among the worst states to be an EV owner.

A new list from EV Charger Reviews puts Texas in the No. 2 position among the worst states for owning an EV. Washington leads the pack of the worst EV states. Topping the list of the best states for EV owners is Maine, followed by Colorado and Vermont.

The ranking judged each state on these factors:

Number of registered EVs
Number of EVs per charging port
Ratio of one square mile per charging port
Cost of electricity
Annual cost savings for EV owners
Number of EVs per service center
EV tax credits

“Texas has cheaper electricity but a bad ratio of EVs registered to charging ports and service centers. The annual savings on gas money is only about $1,000, and there are no tax incentives,” says EV Charger Reviews.

Texas’ ranking stands in contrast to the presence in Austin of Tesla’s headquarters and a Tesla factory. The more than 10 million-square-foot, 25,000-acre factory serves as the U.S. manufacturing hub for Tesla’s electric-powered Model Y car and Cybertruck.

While thousands of Texans are driving Teslas and other EVs, they’re definitely in the minority.

Survey findings released in November 2023 by the University of Houston and Texas Southern University showed that only five percent of Texas motorists who were questioned drove an electric-powered car, truck, or SUV.

Nearly 60 percent of those who didn’t drive EVs said they wouldn’t consider buying one. Almost half (46 percent) cited the lack of charging stations as their chief reason for not wanting to own an EV.

“With such a small percentage of Texans currently owning electric vehicles, it looks like Texans will hold tight to their gas engines for the foreseeable future. Government incentives … have yet to make a difference among the state’s vehicle buyers,” according to a UH news release about the survey.

“But as charging stations grow in number, costs of operation decrease and — most important, the technology allows longer driving ranges — perhaps electric vehicles will start to earn their place in the garages of Texans.”

A Texas law that took effect in 2023 requires an EV owner to pay an extra $200 fee when they renew their vehicle registration or an extra $400 fee for their initial two-year registration.

Houston battery recycling company secures $32M in financing

fresh funding

Houston-based Ace Green Recycling has raised $32 million in private investment in public equity (PIPE) financing to support its future plans for growth.

The battery recycling technology company secured the financing with Athena Technology Acquisition Corp. II, a publicly traded special purpose acquisition company that Ace previously announced it plans to merge with. Once the merger is completed, Ace will become a publicly traded company on the Nasdaq Stock Exchange under the ticker symbol "AGXI."

Ace says the financing will be used to complete the merger and scale the company.

“This investment accelerates our mission to redefine battery recycling at a global scale,” Ace CEO Nischay Chadha said in a news release. “At Ace, we are deploying Greenlead® and LithiumFirst™ as a new standard–fully electrified, Scope 1 emissions-free solutions designed to replace legacy processes and unlock a cleaner supply chain for critical materials. We believe that the future of electrification depends on how efficiently and sustainably we recover these resources, and this milestone brings us meaningfully closer to that future.”

Ace says the funding will also be primarily used to fund capital expenditures related to the development of its planned flagship recycling facility, located outside of Beaumont, Texas. According to a February investor presentation, the facility is expected to launch in 2027. It will recycle lead-acid and lithium-ion batteries.

Ace agreed to a 15-year battery material supply agreement with Miami-based OM Commodities last year, in which OM Commodities would supply Ace with at least 30,000 metric tons of lead scrap to be recycled annually. Switzerland-based Glencore plc agreed to a 15-year offtake agreement to purchase up to 100 percent of ACE’s products from four of its planned lead-acid and lithium-ion battery recycling parks back in 2022.

Ace also reported that the funding will be put toward "supporting the expansion of operations and to fund the purchase of other companies," in the release.

Houston AI startup rolls out platform to reshape oil and gas workflows

AI for energy

Houston-based Collide is looking to solve AI issues in the energy industry from within.

Co-founded by former oil roughneck Collin McLelland, the company has developed AI software for operators and field teams, shaped by firsthand oilfield experience. Its AI-native platform “retrieves and synthesizes data from authoritative sources to deliver accurate, cited, and energy-focused insights to oil and gas professionals,” according to the company.

“Oil and gas has a graveyard full of technology that was technically impressive and operationally useless,” McLelland tells Energy Capital. “The reason is almost always the same: the people who built it didn't understand what they were actually solving for. When you're an outsider, you see workflows and try to automate them. When you're an insider, you understand why those workflows exist—the regulatory constraints, the physical realities, the liability concerns, the trust dynamics between operators and service companies.”

Collide’s large language model, known as RIGGS, performed well in recent benchmarking results when taking a standardized petroleum engineering (SPE) exam, the company reports. The exam assesses understanding from conceptual terminology to complex mathematical problem-solving.

According to Collide, RIGGS achieved a score of 67.5 percent on a 40-question subset of the SPE petroleum engineering exam, outperforming other large language models like Grok 4 (62.5 percent), Claude Sonnet 4.5 (52.5 percent) and GPT 5.1 (4 percent).

RIGGS completed the test in 15 minutes, while Grok took two hours. Collide hopes over the next few months, RIGGS will receive a score between 75 percent to 80 percent accuracy.

The software could potentially help oil and gas companies produce accurate outputs and automate trivial workflows, which can open up valuable time for engineers and teams to work on other pressing matters, according to McLelland.

“Collide exists because we sat in those seats — we were the engineers, the operators, the field guys,” he says. ”RIGGS scoring higher on the PE exam versus the frontier labs isn't a party trick. It's evidence that the model understands petroleum engineering the way a petroleum engineer does, because it was built by people who do.”

RIGGS was trained on Collide’s Spindletop hardware and is supported by a vast library of information, as well as a reasoning engine and validation layer that uses logic to solve problems.

“Longer term, we see RIGGS as the intelligence layer that sits underneath every operator's workflow — not a chatbot you open in a browser, but something embedded in the tools engineers already use,” McLelland says. “The goal is to give every engineer the knowledge and pattern recognition of a 30-year veteran, on demand."

According to McLelland, Collide is already building toward reservoir analysis and production optimization, automated regulatory compliance (Railroad Commission filings, W-10s, G-10s), workover report generation, and engineering decision support in the field for near-term use cases. In March, Collide and Texas-based oil and gas operator Winn Resources announced a collaboration to automate the time-intensive process of filing monthly W-10 and G-10 forms with the Texas Railroad Commission, completing what’s normally a multi-hour task in under 30 minutes. Collide reports that Winn’s infrastructure now automates regulatory filings and provides real-time visibility into data gaps, which has reduced processing time by over 95 percent.

“Before Collide, I'd spend hours manually keying in filings,” Buck Crum, director of operations, said in a news release. “(In March), we had 50 wells to file and I was done in 20 minutes. It does the majority of the heavy lifting while keeping me in control. That human-in-the-loop approach saves meaningful time and gives us greater confidence in our compliance and reporting.”

Collide was originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing.” After raising $5 million in seed funding led by Houston’s Mercury Fund last year, the company said it would shift its focus to rolling out its enterprise-level, AI-enabled solution.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
