Chevron U.S.A., a subsidiary of Houston-based energy company Chevron, has taken its first big step toward establishing a commercial-scale lithium business.

Chevron acquired leaseholds totaling about 125,000 acres in Northeast Texas and southwest Arkansas from TerraVolta Resources and East Texas Natural Resources. The acreage contains a high amount of lithium, which Chevron plans to extract from brines produced from the subsurface.

Lithium-ion batteries are used in an array of technologies, such as smartwatches, e-bikes, pacemakers, and batteries for electric vehicles, according to Chevron. The International Energy Agency estimates lithium demand could grow more than 400 percent by 2040.

“This acquisition represents a strategic investment to support energy manufacturing and expand U.S.-based critical mineral supplies,” Jeff Gustavson, president of Chevron New Energies, said in a news release. “Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers.”

Rania Yacoub, corporate business development manager at Chevron New Energies, said that amid heightening demand, lithium is “one of the world’s most sought-after natural resources.”

“Chevron is looking to help meet that demand and drive U.S. energy competitiveness by sourcing lithium domestically,” Yacoub said.

UH researchers develop breakthrough material to boost efficiency of sodium-ion batteries

eyes on clean energy

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."

Chevron names inaugural cohort of Houston energy innovators

research ready

Anew program from Rice University and Chevron has named its inaugural cohort.

Funded by Chevron, the Chevron Energy Graduate Fellowship will provide $10,000 each to 10 Rice graduate students for the current academic year, which supports research in energy-related fields.

The Rice Sustainability Institute (RSI) hosted the event to introduce the inaugural cohort of the Rice Chevron Energy Graduate Fellowship at the Ralph S. O’Connor Building for Engineering and Science. Director of the RSI and the W. Maurice Ewing Professor in Earth, Environmental and Planetary Sciences, Carrie Masiello presented each fellow with a certificate during the ceremony.

“This fellowship supports students working on a wide range of topics related to scalable innovations in energy production that will lead to the reduction of carbon dioxide emissions,” Masiello says in a news release. “It’s important that we recognize the importance of intellectual diversity to the kind of problem-solving we have to do as we accomplish the energy transition.”

The work of the students focuses on creating "real-world, scalable solutions to transform the energy landscape,” per the Rice release. Recipients of the fellowship will research solutions to energy challenges that include producing eco-friendly hydrogen alternatives to fossil fuels and recycling lithium-ion batteries.

Some of the fellows' work will focus on renewable fuels and carbon-capture technologies, biological systems to sequester carbon dioxide, and the potential of soil organic carbon sequestration on agricultural land if we remove the additionality constraint. Xi Chen, a doctoral student in materials science and nanoengineering, will use microwave-assisted techniques to recycle lithium-ion batteries sustainably.

Rice President Reginald DesRoches began the event by stressing the importance of collaboration. Ramamoorthy Ramesh, executive vice president for research at Rice, echoed that statement appearing via Zoom to applaud the efforts of doing what is right for the planet and having a partner in Chevron.

“I’m excited to support emerging leaders like you all in this room, who are focused on scalable, innovative solutions because the world needs them,” Chris Powers, vice president of carbon capture, utilization and storage and emerging at Chevron New Energies and a Rice alum, says at the event. “Innovation and collaboration across sectors and borders will be key to unlocking the full potential of lower carbon energies, and it’s groups like you, our newest Chevron Fellows, that can help move the needle when it comes to translating, or evolving, the energy landscape for the future.”

Houston scientists discover breakthrough process for lithium-ion battery recycling

future of EVs

With the rise of electric vehicles, every ounce of lithium in lithium-ion batteries is precious. A team of scientists from Rice University has figured out a way to retrieve as much as 50 percent of the material in used battery cathodes in as little as 30 seconds.

Researchers at Rice University’s Nanomaterials Laboratory led by Department of Materials Science and NanoEngineering Chair Pulickel Ajayan released the findings a new study published in Advanced Functional Materials. Their work shows that the process overcomes a “bottleneck” in lithium-ion battery recycling technology. The researchers described a “rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent,” according to a news release.

Past recycling methods have involved harsh acids, and alternative eco-friendly solvents like deep eutectic solvents (DESs) at times have not been as efficient and economically viable. Current recycling methods recover less than 5 percent of lithium, which is due to contamination and loss during the process.

In order to leach other metals like cobalt or nickel, both the choline chloride and the ethylene glycol have to be involved in the process, according to the researchers at Rice. The researchers submerged the battery waste material in the solvent and blasted it with microwave radiation since they knew that of the two substances only choline chloride is good at absorbing microwaves.

Microwave-assisted heating can achieve similar efficiencies like traditional oil bath heating almost 100 times faster. Using the microwave-based process, Rice found that it took 15 minutes to leach 87 percent of the lithium, which differs from the 12 hours needed to obtain the same recovery rate via oil bath heating.

“This method not only enhances the recovery rate but also minimizes environmental impact, which makes it a promising step toward deploying DES-based recycling systems at scale for selective metal recovery,” Ajayan says in the release.

Due to rise in EV production, the lithium-ion battery global market is expected to grow by over 23 percent in the next eight years, and was previously valued at over $65 billion in 2023.

“We’ve seen a colossal growth in LIB use in recent years, which inevitably raises concerns as to the availability of critical metals like lithium, cobalt and nickel that are used in the cathodes,” the study's co-author, Sohini Bhattacharyya, adds. “It’s therefore really important to recycle spent LIBs to recover these metals.”

NASA awards Texas Space Commission role in $10M aerospace workforce initiative

space hub

The Texas Space Commission is one of seven organizations tapped by NASA to lead the space agency's new state and regional Skilled Technical Workforce Hubs.

The $10.5 million initiative aims to help foster the next generation of skilled workers in the aerospace industry.

Through the new program, the hubs will work together over the next three years to meet growing industry needs by aligning “industry employers, community colleges, high school career and technical education programs, and workforce systems,” according to a news release from NASA.

It aims to create clear pathways for workers in technical jobs, like welding, electrical work and machining, plus other jobs that require advanced STEM knowledge but do not require a bachelor’s degree.

“The need for technical talent is already urgent and will only continue to grow as we return humanity to the Moon and set our sights on Mars and beyond,” Elaine Ho, associate administrator for the Office of STEM Engagement at NASA, said in the release. “NASA is uniquely positioned to be the catalyst and convener that accelerates America’s aerospace workforce development and fosters the next generation of technicians.”

As part of the initiative, the TSC plans to launch the statewide network known as the Texas Space STEM Alliance (TSSA). According to a TSC release, the TSSA will link up schools, colleges, workforce groups and aerospace companies to build a pipeline for space-industry workers.

Additionally, the TSC is developing the Texas Aerospace Pathways Plus (TAP+) portal to consolidate information on training programs, internships, apprenticeships, employment opportunities and scholarships, while also identifying regional gaps in workforce opportunities.

Other state and regional organizations to receive the award include:

  • Antelope Valley Community College District in Lancaster, California
  • Georgia Tech Research Corporation
  • Minnesota State Colleges and Universities
  • Southern Utah University
  • Space Florida
  • State Board for Community Colleges and Occupation Education, Arapahoe Community College in Littleton, Colorado

The Houston area is home to more than 43,000 aerospace and aviation professionals, according to the Greater Houston Partnership. The Texas Space Commission has been awarded $150 million for 24 projects since being established to increase the state’s space economy in 2023.

The funding for the NASA state hubs comes from NASA’s Office of STEM Engagement through its Next Gen STEM Project.

Amazon's robotaxi service Zoox rolls out in 'sprawling' Houston market

On the Road

Amazon-owned robotaxi ride-hailing service Zoox is zooming into Houston in September, becoming the latest robotaxi operator jockeying for local riders.

Initially, self-driving retrofitted SUVs with safety drivers on board will serve downtown Houston, centrally located tourist hotspots, and certain residential neighborhoods. The SUVs will test Houston roads before Zoox rolls out autonomous robotaxis here, the company says.

Zoox takes Houston for a test drive

At the outset, Zoox says, a limited number of vehicles will be driven by people to gather data about Houston roads.

“This helps create a detailed picture of each street, from road geometry to traffic lights,” the company says. “Once we have mapped out an area, we will test autonomous driving capabilities. Safety and operational readiness govern the pace of our rollout.”

Zoox says its robotaxi differs from vehicles operated by other ride-hailing services.

The all-electric robotaxi “is purpose-built for autonomous ride-hailing and designed for riders from day one,” the company says. “It has no traditional driving controls and instead has carriage-style seating, sliding glass doors, and features that let the rider personalize their journey.”

To help manage the fleet, Zoox plans to open a depot in Houston for vehicle charging and maintenance, a representative says via email.

Along with Houston, Zoox is launching this month in San Diego. The ride-hailing service already operates in Austin, Dallas, Atlanta, Las Vegas, Los Angeles, Miami, Phoenix, the San Francisco Bay Area, Seattle, and Washington, D.C.

Zoox breaks into “sprawling” Houston market

Zoox describes Houston as its “most sprawling market to date.”

“Driving here means navigating complex service-road networks, unique merging scenarios, and challenging environmental conditions, including severe heat, heavy rain, and urban flooding,” the company says. “It’s a rigorous test of our technology across geography and terrain.”

Zoox will join two other autonomous ride-hailing services in Houston:

  • Waymo began rolling in Houston in February. Alphabet, the parent company of Google, owns Waymo.
  • Electric vehicle manufacturer Tesla began offering robotaxi services earlier this year.

A third Zoox competitor is arriving within the next year. A partnership comprising rideshare provider Uber, EV manufacturer Lucid, and autonomous technology company Nuro plans to launch a robotaxi service in Houston by mid-2027.

Houston energy giant Shell lists local headquarters for sale for $325M

On the Market

Energy giant Shell has put its U.S. headquarters in Houston’s Energy Corridor on the market and is exploring the sale of its U.S. chemical business.

Green Street News reported Shell just listed its longtime Energy Corridor campus at 150 N. Dairy Ashford Road. The asking price is $325 million, The Real Deal reported. Shell plans to lease back half of the nearly 1.5 million-square-foot Woodcreek campus for 15 years.

A sale-leaseback deal could transform the 43.6-acre campus into a multitenant hub, CoStar News reported.

“Houston is a critical hub for Shell globally and the headquarters of our U.S. businesses,” a Shell spokesperson told the Houston Business Journal. “We remain committed to Houston and are evaluating opportunities to optimize our Woodcreek campus as part of our ongoing review of workplace needs while maintaining a strong presence in the city.”

Shell occupied its first building at the West Houston campus in 1980. The company employs more than 6,000 people in Texas.

Shell is one of the highest-profile businesses occupying space in the Energy Corridor. It’s home to 67,000 workers, more than 27 million square feet of office and mixed-use space, and 3.8 million square feet of retail and restaurant space.

Shell considers $8B sale of chemical business
As the company seeks to unload its Woodcreek campus, The Financial Times reported Shell is looking into selling its U.S. chemical business. The price tag: $8 billion.

Potential buyers include Spring-based ExxonMobil and Houston-based LyondellBasell.

Shell operates four chemical plants in Texas, Louisiana and Pennsylvania, producing an array of chemicals for use in plastics, detergents and pharmaceuticals.

Shell CEO Wael Sawan said last year that the company had spent $45 billion in capital “that is underperforming for us,” split between its chemical business and renewable energy arm.

Shell also agreed to sell its solar and wind power business in India this summer. Read more here.
