Houston researchers make breakthrough on electricity-generating bacteria

new findings

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.”

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."

Houston geothermal startup adds former bp, Calpine execs to C-suite

new leaders

XGS Energy, a Houston-based developer of geothermal power systems, has added several energy industry veterans to its C-suite this summer.

The company named Al Vickers as its new chief operating officer earlier this month. Vickers will replace Ghazal Izadi in the role, as she moves into the chief growth officer position.

Vickers previously served as CEO of bp's U.S. Low Carbon Energy business and most recently was COO of Houston-based Grid United, which develops next-generation transmission infrastructure.

“I have spent my career developing, building, and operating large, complex energy infrastructure, and I am excited to work with XGS’s proven technology, which is ready to deliver clean, round-the-clock power at the scale the grid and customers need,” Vickers said in a news release. “XGS sits at the intersection of innovation, affordability, demand growth, responsible infrastructure development, and long-term energy resilience. I’m excited to roll up my sleeves and apply best practices from both oil and gas and infrastructure development to deliver gigawatt-scale geothermal projects.”

Kurt Fricker, who most recently held leadership roles at Hess Corporation, was also announced as XGS's new chief procurement officer.

The hires come shortly after XGS announced Richard Chong as its new chief financial officer in May.

Chong joins XGS from Houston-based power producer Calpine, where he most recently was vice president of finance. His work there included leading $2.25 billion in financing for Geysers, the world’s largest geothermal power complex.

Chong says XGS’ proven technology and the rising demand for clean power will help the company execute on its multi-gigawatt pipeline.

“I look forward to applying the experience I’ve built over two decades in energy finance to help XGS deliver clean, reliable power to customers and unlock the massive development opportunity ahead for next-generation geothermal,” Chong said in the release.

XGS’ first project is a 150-megawatt geothermal facility in New Mexico. It will supply around-the-clock electricity to the grid operated by Public Service Co. of New Mexico in support of Meta data centers.

XGS recently tapped Houston-based energy technology company Baker Hughes to provide engineering services for the New Mexico project.

XGS’ geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock exists — without the need for water resources or specific geological conditions. This results in lower-risk projects, more site options, easier permitting and faster deployment.

Since 2023, XGS has raised nearly $57 million in venture capital.

XGS launched in 2008 in Palo Alto, California, as Geothermic Solution. In conjunction with its Series A round in 2023, the company rebranded to its current name. The company recently moved its headquarters to Houston, according to the Houston Business Journal.
