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.”

ERCOT steps up grid innovation efforts to support growing power demand

grid boost

As AI data centers gobble up more electricity, the Electric Reliability Council of Texas (ERCOT) — whose grid supplies power to 90 percent of Texas — has launched an initiative to help meet challenges presented by an increasingly strained power grid.

ERCOT, based in the Austin suburb of Taylor, said its new Grid Research, Innovation, and Transformation (GRIT) initiative will tackle research and prototyping of emerging technology and concepts to “deeply understand the implications of rapid grid and technology evolution, positioning ERCOT to lead in the future energy landscape.”

“As the ERCOT grid continues to rapidly evolve, we are seeing greater interest from industry and academia to collaborate on new tools and innovative technologies to advance the reliability needs of tomorrow’s energy systems,” ERCOT President and CEO Pablo Vegas said in a news release. “These efforts will provide an opportunity to share ideas and bring new innovations forward, as we work together to lead the evolution and expansion of the electric power grid.”

In conjunction with the GRIT initiative, ERCOT launched the Research and Innovation Partnership Engagement (RIPE) program. The program enables partners to work with ERCOT on developing technology aimed at resolving grid challenges.

To capitalize on ideas for grid improvements, the organization will host its third annual ERCOT Innovation Summit on March 31 in Round Rock. The summit “brings together thought leaders across the energy research and innovation ecosystem to explore solutions that use innovation to impact grid transformation,” ERCOT said.

“As the depth of information and industry collaboration evolves, we will continue to enhance the GRIT webpages to create a dynamic and valuable resource for the broader industry to continue fostering strong collaboration and innovation with our stakeholders,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation.

ERCOT’s GRIT initiative comes at a time when the U.S. is girding for heightened demand for power, due in large part to the rise of data centers catering to the AI boom.

A study released in 2024 by the Electric Power Research Institute (EPRI) predicted electricity for data centers could represent as much as 9.1 percent of total power usage in the U.S. by 2030. According to EPRI, the share of Texas electricity consumed by data centers could climb from 4.6 percent in 2023 to almost 11 percent by 2030.

A report issued in 2024 by the federal government’s Lawrence Berkeley National Laboratory envisions an even faster increase in data-center power usage. The report projected data centers will consume as much as 12 percent of U.S. electricity by 2028, up from 4.4 percent in 2023.

In 2023, the EPRI study estimated, 80 percent of the U.S. electrical load for data centers was concentrated in two states, led by Virginia and Texas. The University of Texas at Austin’s Center for Media Engagement reported in July that Texas is home to 350 data centers, second only to Virginia.

“The U.S. electricity sector is working hard to meet the growing demands of data centers, transportation electrification, crypto-mining, and industrial onshoring, while balancing decarbonization efforts,” David Porter, EPRI’s vice president of electrification and sustainable energy strategy, said. “The data center boom requires closer collaboration between large data center owners and developers, utilities, government, and other stakeholders to ensure that we can power the needs of AI while maintaining reliable, affordable power to all customers.”

Policy adviser tapped to lead ‘nuclear renaissance’ in Texas

going nuclear

As Texas places a $350 million bet on nuclear energy, a budget and policy adviser for Gov. Greg Abbott has been tapped to head the newly created Texas Advanced Nuclear Energy Office.

Jarred Shaffer is now director of the nuclear energy office, which administers the $350 million Texas Advanced Nuclear Development Fund. The fund will distribute grants earmarked for the development of more nuclear reactors in Texas.

Abbott said Shaffer’s expertise in energy will help Texas streamline nuclear regulations and guide “direct investments to spur a flourishing and competitive nuclear power industry in the Lone Star State. Texas will lead the nuclear renaissance.”

The Texas Nuclear Alliance says growth of nuclear power in the U.S. has stalled while China and Russia have made significant gains in the nuclear sector.

“As Texas considers its energy future, the time has come to invest in nuclear power — an energy source capable of ensuring grid reliability, economic opportunity, and energy and national security,” Reed Clay, president of the alliance, said.

“Texas is entering a pivotal moment and has a unique opportunity to lead. The rise of artificial intelligence and a rebounding manufacturing base will place unprecedented demands on our electricity infrastructure,” Clay added. “Meeting this moment will require consistent, dependable power, and with our business-friendly climate, streamlined regulatory processes, and energy-savvy workforce, we are well-positioned to become the hub for next-generation nuclear development.”

Abbott’s push for increased reliance on nuclear power in Texas comes as public support for the energy source grows. A 2024 survey commissioned by the Texas Public Policy Institute found 55 percent of Texans support nuclear energy. Nationwide support for nuclear power is even higher. A 2024 survey conducted by Bisconti Research showed a record-high 77 percent of Americans support nuclear energy.

Nuclear power accounted for 7.5 percent of Texas’ electricity as of 2024, according to the Nuclear Energy Institute, but made up a little over 20 percent of the state’s clean energy. Currently, four traditional reactors produce nuclear power at two plants in Texas. The total capacity of the four nuclear reactors is nearly 5,000 megawatts.

Because large nuclear plants take years to license and build, small factory-made modular reactors will meet much of the shorter-term demand for nuclear energy. A small modular reactor has a power capacity of up to 300 megawatts. That’s about one-third of the generating power of a traditional nuclear reactor, according to the International Atomic Energy Agency.

A report from BofA Global Research predicts the global market for small nuclear reactors could reach $1 trillion by 2050. These reactors are cheaper and safer than their larger counterparts, and take less time to build and produce fewer CO2 emissions, according to the report. Another report, this one from research company Bloomberg Intelligence, says soaring demand for electricity — driven mostly by AI data centers — will fuel a $350 billion boom in nuclear spending in the U.S., boosting output from reactors by 63 percent by 2050.

Global nuclear capacity must triple in size by 2050 to keep up with energy demand tied to the rise of power-gobbling AI data centers, and to accomplish decarbonization and energy security goals, the BofA report says. Data centers could account for nine percent of U.S. electricity demand by 2035, up from about four percent today, according to BloombergNEF.

As the Energy Capital of the World, Houston stands to play a pivotal role in the evolution of small and large nuclear reactors in Texas and around the world. Here are just three of the nuclear power advancements that are happening in and around Houston:

Houston is poised to grab a big chunk of the more than 100,000 jobs and more than $50 billion in economic benefits that Jimmy Glotfelty, a former member of the Texas Public Utility Commission, predicts Texas will gain from the state’s nuclear boom. He said nuclear energy legislation signed into law this year by Abbott will provide “a leg up on every other state” in the race to capitalize on the burgeoning nuclear economy.

“Everybody in the nuclear space would like to build plants here in Texas,” Inside Climate News quoted Glotfelty as saying. “We are the low-regulatory, low-cost state. We have the supply chain. We have the labor.”
