Apache Corp. and the Borderlands Research Institute (BRI) at Sul Ross State University in Alpine, Texas, have partnered to launch a well pad restoration research project.

Researchers at BRI and Texas Native Seeds will investigate methods to improve habitat restoration efforts in the Permian Basin. The goal is to publish a scientific best practices reclamation document for the Permian operators. Texas Native Seeds is a project of the Caesar Kleberg Wildlife Research Institute at Texas A&M Kingsville. BRI works mostly in the frontier of Texas and throughout the Southwest.

The BRI project aims to inform oil and gas industries in the Permian about how changes in the industry’s collaborative approach to restoring end-of-service well pads can benefit local biodiversity and reunite fragmented habitats.

At end of a well’s service life, when the well is plugged, equipment is removed, and the pad is reseeded, which allows it to gradually return to a natural condition. The project’s goal is to help accelerate a better return to nature by considering alternative soil preparation techniques. By adding biochar to improve soil fertility, and incorporating undesirable scrub brush as a vegetative cover to hold soil moisture and discourage grassland animals from foraging on the seeds before they germinate, researchers believe this could be done.

“We are honored to partner with the Borderlands Research Institute on this important effort, which aligns with our mission to meet the growing demand for energy and to do so in a cleaner, more sustainable way,” Jessica Jackson, Apache’s Vice President of Environment, Health and Safety, says in a news release. “For many years, Apache has worked to restore well pads to their habitat potential. To further our efforts to continuously improve, Apache is supporting scientific research at sites in the Permian Basin to study the efficacy of methods for habitat restoration.”

The project will also measure increases in soil carbon to passively sequester CO2 in healthy desert soils, which will support Sul Ross State University student research through BRI.

“We all depend on the energy produced in the Permian Basin to power our lives, and we look forward to bringing valuable science to the table to support enhanced restoration practices in the energy industry,” Dr. Louis Harveson, the Dan Allen Hughes, Jr. Endowed Director of Borderlands Research Institute adds in the release. “We appreciate the opportunity to partner with Apache on this important research and applaud their leadership on this issue.”

A View From HETI

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
