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.”

Experts from the University of Houston are teaming up with the city on key sustainability efforts.

University of Houston collaborates with county on future-facing sustainability efforts

dream team

Researchers at the University of Houston are partnering with the Harris County Office of County Administration’s Sustainability Office, the Harris County Energy Management Team, and other county staff in an effort to develop a comprehensive baseline of energy use and energy-use intensity that will aim to reduce energy costs and emissions in county facilities.

Once fully established, the team will work on tracking progress and evaluating the effectiveness of energy-saving measures over time. They will begin to build the foundation for future programs aimed at maximizing savings, reducing energy consumption, and increasing the use of renewable energy sources in county operations.

Harris County energy managers, Glen Rhoden and Yas Ahmadi, will work with UH professionals, including:

Jian Shi, UH Cullen College of Engineering associate professor of engineering technology and electrical and computer engineering
Zhu Han, Moores professor of electrical and computer engineering
Xidan "Delia" Zhang, UH research intern

The group began collaborating a year ago, and analyzed energy consumption data from county facilities.They were able to successfully identify key summertime energy-saving opportunities and completed retro-commissioning of four county buildings. Those efforts saved over $230,000 annually in electricity costs.

“This project is a prime example of how impactful research at UH can be when applied to real-world challenges, delivering tangible benefits to both the environment and the communities we serve,” Shi says in a news release.

The team will plan to do additional building projects, which includes the development of solar energy and heat pump initiatives, building automation system upgrades, and LED lighting installations. The goal is to reduce electricity usage by at least 5 percent per year for county facilities by 2030 and cut greenhouse gas emissions by 50 percent over the next 5 years for county buildings.

“Addressing climate change and the energy transition requires a collaborative effort that is not only data-driven and action-oriented but also human-centric,” Shi adds. “It’s about more than just technology—it’s about improving the quality of life for Texans.”

Houston researcher scores $500,000 award to continue on work on energy transition

zeroing in on zero emissions

A University of Houston professor and researcher is laser focused on his work within the energy transition, and National Science Foundation has taken note, awarding him over half a million dollars in funding.

Jian Shi, an assistant professor within the Cullen College of Engineering, recently received the NSF's CAREER award, which will dole out $500,861 in funding through February 2029.

The award was granted for his research, entitled “A Unified Zero-Carbon-Driven Design Framework for Accelerating Power Grid Deep Decarbonization.”

“One of the most major challenges inherent in energy transition is the cost. While reducing carbon emissions serves the best interest of society in the long run, the short-term financial burdens also need to be carefully evaluated to ensure that we have a safe, affordable, reliable and just transition for all,” Shi says in a UH news release. “This challenge has inspired me to work on the innovative framework of “ZERO-Accelerator.”

Shi's ZERO-Accelerator is focused on taking standard carbon-driven tools and integrating them into current power grid operational practices. Shi is the director and founder of SOAR, or the Smart and ZerO-Carbon Energy Analytics and Research Lab.

“It synthesizes interactions from multiple key stakeholders involved in the electricity ecosystem,” says Shi. “The framework considers how to manage carbon allowance allocation and trading for electricity producers, how to maintain a 24/7 zero-carbon power grid for power grid operators and how to enable consumers to understand their carbon footprint and participate in the zero-carbon grid operation.”

In his CAREER proposal, Shi explains that he is also contributing to training the future energy workforce. He adds that he shares this award with his colleagues.

“I believe no accomplishment is truly individual,” he says. “Rather, it is a collective triumph achieved through collaboration, support and shared dedication. As I reflect on the milestones I've reached, I am compelled to express my deepest gratitude to my esteemed colleagues whose unwavering commitment has been instrumental in not just my collective success, but our collective success as well."

Last summer, Shi mentored a UH team in the inaugural American-Made Carbon Management Collegiate Competition, hosted by the U.S. Department of Energy's Office of Fossil Energy and Carbon Management. The team, GreenHouston, took third place in the competition, securing a $5,000 cash prize.

Energy AI company opens first U.S. office in Houston after Halliburton deal

houston expansion

Building on its partnership with Houston-based oilfield services provider Halliburton, energy-sector AI company Shape Digital recently opened an office at The Ion. It’s the company’s first U.S. location.

Shape Digital’s workforce in Houston includes employees specializing in tech support, business development and client services. The company’s local hiring projections and headcount weren’t available. The new office will be located within Industrious at the Ion, according to Rice Alliance.

A key driver of the new Houston office: The company forecasts North America will account for more than 20 percent of its business in 2027.

“North America is a critical market for industrial innovation, and Houston sits at the center of companies driving that progress,” Caio Sene, vice president of client services at Shape Digital, said in a release. “Growing our presence here allows us to work alongside operators as they look for practical ways to turn existing operational data into clear recommendations for what to do next.”

Shape Digital, which also has offices in Singapore and Brazil, develops decision-making platforms for the oil and gas sector.

The Ion District office gives Shape Digital a presence close to Halliburton’s headquarters. In May, the two companies forged a partnership to combine Halliburton’s Digital Field Solverdecision-making system with Shape Digital’s AI portfolio.

Shape Digital layers AI software atop existing operations data rather than replacing legacy systems or adding new software.

The company’s suite of AI agents draws on more than 200 operations-monitoring algorithms, continually learning from company and industry data. The suite comprises four products: Shape Aura, Shape Lighthouse, Shape Lumen and Shape Reef.

Shape Digital says that by working with a customer’s existing operations data, it can deliver ROI in less than two months without any additional investment in equipment or infrastructure.

The company is a 2021 spinoff of Japan-based Modec. Modec builds, owns, and operates floating offshore oil and gas production facilities. Its Modec America subsidiary is based in Houston.

Houston energy startup names former Cheniere execs to C-suite

new leaders

Houston-based energy infrastructure startup Joulent has brought aboard a new chief financial officer and new chief operating officer—both former executives at Houston-based Cheniere Energy.

The C-suite moves come three months after Joulent raised $1.75 billion from National Grid Ventures.

Michael Wortley joins Joulent as co-president and CFO. Wortley most recently was executive vice president and CFO at Cheniere, an LNG producer and exporter.

In conjunction with Wortley’s hiring, Brian Boland, who was Joulent’s interim CFO, has been named executive vice president, chief investment officer, and head of strategy.

Corey Grindal comes to Joulent as co-president and COO. Grindal most recently was executive vice president and COO at Cheniere.

“As Joulent evolves to meet the growing demand for power infrastructure, our expanded leadership team will help ensure we continue delivering the execution certainty our customers, partners, and investors expect,” Chris James, Joulent’s founder and CEO, said in a press release.

“Corey and Michael are accomplished operators with exceptional records of building and leading world-class energy infrastructure businesses, where they have embedded a culture defined by operational excellence and disciplined execution,” James added.

Joulet builds dedicated power-generating facilities that feed directly into data centers and other power-dependent facilities. This eliminates the need for companies to draw power from grids.

“With an initial multi-gigawatt development portfolio and strategic partnerships across the energy, infrastructure, and data center ecosystem, Joulent is helping remove power constraints to enable the next chapter of American innovation and U.S. reindustrialization,” the company says.

The $1.75 billion minority investment from National Grid Ventures complements Joulent’s existing partnerships.

Joulent, founded in 2023, emerged from stealth mode this summer. The company was founded by investment firm Engine No. 1.

Joulent’s first project, the Project Kilby natural gas facility in West Texas, will be co-located with a Microsoft data center. It’ll deliver about 2.67 gigawatts of power under a 20-year deal between Microsoft and Energy Forge One, a 50/50 joint venture between Chevron and Joulent.

Lithium refiner expands into Houston with new Energy Corridor office

new to hou

Battery-grade lithium carbonate manufacturer Stardust Power has expanded into Houston’s Energy Corridor, the company tells Energy Capital.

The company’s new office will serve as a project execution hub to support operations and planning for the company’s forthcoming lithium refinery in Muskogee, Oklahoma, according to a news release. The Greenwich, Connecticut-based, publicly traded company says the facility will be one of the largest lithium refining operations in the United States. The refinery is expected to have production capacity of up to 50,000 metric tons per year and seeks to address the critical shortage of U.S. lithium refining capacity.

Battery-grade lithium carbonate is commonly used in electric vehicle batteries and energy storage systems.

The company says it chose Houston as the location for its new execution hub for its rich history of expertise in engineering, a robust energy infrastructure ecosystem, and access to a leading talent pool for engineering, procurement and construction professionals. The Houston project hub will work closely with the company’s existing office in Oklahoma City.

“The Houston office strengthens our operational footprint at a critical phase of development,” Chris Celano, COO of Stardust Power, said in the release. “By building out a dedicated project management hub in one of the most experienced energy markets in the world, we are positioning the Company for execution as we advance the Muskogee refinery.”

Currently, the Houston office plans to accommodate a workforce of about 20 people with the possibility to add staff upon reaching project milestones, according to a representative from the company.

“This expansion reflects our commitment to deliver domestic, battery-grade lithium that supports U.S. energy security and industrial growth,” Celano added in the release.

In August, Stardust Power secured an offtake agreement to supply up to 20,000 metric tons of battery-grade lithium carbonate by 2030 from the Muskogee, Oklahoma, refinery to New York-based battery technology company Charge CCCV. Stardust reports that the deal adds to a separate non-binding agreement for up to 25,000 metric tons annually for 10 years with an undisclosed global trading company.
