New research from Rice University that merges biology with electrochemistry has uncovered new findings on how some bacteria generate electricity.

Led by Caroline Ajo-Franklin, a Rice professor of biosciences and the director of the Rice Synthetic Biology Institute, the team published its findings in the journal Cell in April. The report showed how some bacteria use compounds called naphthoquinones, rather than oxygen, to transfer electrons to external surfaces in a process known as extracellular respiration. In other words, the bacteria are exhale electricity as they breathe.

This process has been observed by scientists for years, but the Rice team's deeper understanding of its mechanism is a major breakthrough, with implications for the clean energy and industrial biotechnology sectors, according to the university.

“Our research not only solves a long-standing scientific mystery, but it also points to a new and potentially widespread survival strategy in nature,” Ajo-Franklin, said in a news release.

The Rice team worked with the University of California, San Diego's Palsson lab to simulate bacterial growth using advanced computer modeling. The simulations modeled oxygen-deprived environments that were rich in conductive surfaces, and found that bacteria could sustain themselves without oxygen. Next, they confirmed that the bacteria continued to grow and generate electricity when placed on conductive materials.

The team reports that the findings "lay the groundwork for future technologies that harness the unique capabilities" of these bacteria with "far-reaching practical implications." The team says the findings could lead to significant improvements in wastewater treatment and biomanufacturing. They could also allow for better bioelectronic sensors in oxygen-deprived environments, including deep-sea vents, the human gut and in deep space.

“Our work lays the foundation for harnessing carbon dioxide through renewable electricity, where bacteria function similarly to plants with sunlight in photosynthesis,” Ajo-Franklin added in the release. “It opens the door to building smarter, more sustainable technologies with biology at the core.”

SLB and NVIDIA expand partnership to scale AI across energy sector

AI partnership

Houston-based energy technology company SLB has expanded its 18-year tech collaboration with chipmaker NVIDIA to include the development of an “AI factory for energy.”

Through their partnership, SLB and NVIDIA will create AI infrastructure and models built around SLB’s existing digital platforms to help energy companies scale AI for data and operations.

In addition to the development of the “AI factory,” SLB will:

  • Provide modular design services to enhance NVIDIA’s blueprint for building, launching and operating gigawatt-scale AI data centers. In this case, modular design involves manufacturing data center components off-site.
  • Use NVIDIA’s AI infrastructure to improve the processing of large datasets and AI models across SLB’s digital platforms.

Energy companies generate vast amounts of operational data, which can slow down and silo decision-making, SLB says. By combining NVIDIA’s Omniverse libraries and its Nemotron open models with SLB’s digital and AI platforms, the companies aim to more rapidly transform data into actionable insights.

Omniverse libraries are sets of prebuilt 3D elements, such as objects, surfaces and interactive features, that make it easier to construct detailed virtual spaces without having to design everything manually. They’re commonly used for building immersive environments, digital replicas of real-world systems and simulation scenarios.

Nemotron open models are AI models that are freely available to download and modify. Instead of relying on a hosted service, you can run them on your own infrastructure and tailor them to fit specific needs.

Vladimir Troy, vice president of AI infrastructure at NVIDIA, says the energy sector is at the forefront of AI driving a “new industrial revolution.”

“The winners in AI will be companies with the best data, the deepest domain expertise, and the ability to scale,” Demos Pafitis, SLB’s chief technology officer, added. “By collaborating with NVIDIA to advance modular data center construction and harness our domain expertise and digital platforms, we’re enabling the energy industry to deploy AI at scale and transform operational data into smarter decisions.”

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer 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.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.
