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

A study from researchers at Rice University could lead to future advances in superconductors with the potential to transform energy use. The study revealed that electrons in strange metals, which exhibit unusual resistance to electricity and behave strangely at low temperatures, become more entangled at a specific tipping point, shedding new light on these materials. The materials share a close connection with high-temperature superconductors, which have the potential to transmit electricity without energy loss, according to the researchers. By unblocking their properties, researchers believe this could revolutionize power grids and make energy transmission more efficient.

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries. The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

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 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.

Houston researchers develop strong biomaterial that could replace plastic

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic. The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties.” Ultimately, the scientists hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth. Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

Bill Gates talks AI, future of energy at CERAWeek address in Houston

overheard

Bill Gates, renowned co-founder of Microsoft and founder of Breakthrough Energy, took the CERAWeek stage to a standing-room-only crowd to discuss his thoughts on the future of energy.

He was joined in conversation with Daniel Yergin, author and vice chairman of S&P Global, at the luncheon on Thursday, March 21. His remarks touched on three themes within the energy transition.

Texas as a hub for energy transition

Yergin started off the conversation inquiring about Gates and his recent tour around Texas, which included visiting energy companies' plants and facilities and their local communities. Though it might surprise people, given the history of oil and gas in the state, Texas has a strong presence in the energy transition, Gates says.

“There is some irony in the fact that so many of the capabilities to embrace (the energy transition) are here in Texas, whether it's the workforce or the permitting,” he says at the event.

Gates adds that while most of the portfolio companies at Breakthrough Energy were founded on the coasts, many turn to Texas when it comes time for their first commercial pilot.

He addressed a progress report on the energy transition as a whole.

“It’s really starting to move. There’s a lot of exciting technologies, and a lot of the big companies are coming in,” he says, specifically noting energy companies' presence at COP28.

“A heroic effort is beginning — I’m very excited about it. But we shouldn’t underestimate how difficult it will be,” he says. “There’s a lot of things that have to happen for these projects to go ahead. It’s far more difficult than anything I worked on at Microsoft.”

Steel and nuclear have big potential for disruption

Gates continued this thought but highlighting that some industries are less advanced than others.

“We’re just at the beginning of many things," he adds, noting that "the steel industry today is 99 percent the traditional process."

With that, steel has a lot of potential to be disrupted, and Breakthrough Energy has two companies working to make the industry greener, but it's an industry that's going to take time to evolve.

Nuclear is another sector Gates is excited about but is developing at a slower pace. Breakthrough Energy has five portfolio companies focused on Nuclear, including TerraPower, which Gates co-founded in 2006.

Despite nearly two decades of development, Gates says TerraPower is a "fast-moving" nuclear company in comparison to other companies out there.

AI's impact is still to be determined

The topic of artificial intelligence inevitably came up, and Gates explains that the technology has come a long way. Microsoft owns a portion of OpenAI, which created ChatGPT. Gates says he expected AI to evolve and to be able to be programmed to understand information to take longer to develop.

“We have achieved a threshold — an unusual threshold because we know how we’ve caused the knowledge represented, but we don’t understand how at a semantic level how that knowledge is being represented,” Gates says.

AI's current applications are within white collar activities, Gates explains, citing writing a regulatory permit or looking at evidence in a lawsuit. He explains that current AI capabilities could continually grow or remain stagnant for a while, he isn't sure.

"The thing that’s daunting is we don’t know how quickly it will improve," he adds.

Gates didn't comment on energy specific AI applications but noted that AI has advanced far past robotics, which would target blue collar roles.

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Houston lawmaker may kill data center tax breaks due to $8B revenue loss

looking at the data

An influential Houston-area state senator is raising concerns about potentially billions of dollars in lost state revenue from tax breaks for Texas data centers—and is pondering legislation that would abolish the tax incentives.

Citing data from the state comptroller’s office, The Texas Tribune reports the state stands to lose nearly $8 billion in revenue from 2026 to 2030 due to sales tax and use tax exemptions for data centers. During the state’s 2025 fiscal year, which ended on Aug. 31, these tax exemptions caused Texas to lose a little over $1 billion, up from an earlier estimate of $130 million.

“These new numbers are extremely concerning, and I will say they’re unsustainable,” Republican state Sen. Joan Huffman, chairwoman of the state Senate Finance Committee, tells The Texas Tribune. “I plan to look at filing legislation to either repeal the exemption or take a very close look at it and see.”

Texas on track to be No. 1 data center market in U.S.

Scrutiny of the tax breaks comes amid an explosion of data center development in Texas, where data provider Aterio identifies nearly 1,000 centers that are operating, under construction or planned.

A report issued in January by Bloom Energy says the state is poised to become the No. 1 U.S. market for data centers within three years. By 2028, according to the report, Texas is projected to exceed 40 gigawatts of data center capacity—representing nearly 30 percent of total U.S. demand.

Among companies benefiting from the data center boom are:

  • Tech titans like Apple, Google, Meta Platforms, and Microsoft, which are spending billions of dollars to build data centers in Texas.
  • Spring-based ExxonMobil and Houston-based Chevron, two oil and energy giants that are developing natural gas plants to supply power for data centers.
  • Houston-based energy technology company Baker Hughes, which is collaborating with Google Cloud to develop AI-enabled power optimization and sustainability software for data centers.
  • DataBank, Data Foundry, Equinix, Digital Realty, Lumen Technologies, and IBM, all of which operate data centers in the Houston area.

The Texas Legislature will begin debating tax breaks for data centers in July, when Huffman’s Senate Finance Committee meets for an interim hearing before the 2027 legislative session, according to the Tribune.

Data center industry defends tax breaks

Leaders in the data center industry warn that watering down or halting the tax breaks could slow down or even end Texas’ ascent in the data center sector.

A 2025 report commissioned by the Data Center Coalition found that in 2024, data centers provided more than $1.6 billion in state tax revenue and almost $1.6 billion in local tax revenue in Texas. Over the next several years, according to the report, planned development of data centers in the Lone Star State could generate almost $3.8 billion in state tax revenue and more than $4.9 billion in local tax revenue.

In 2024, the Houston area had 8.1 million gross square feet of data centers, with the properties’ real estate investments sitting at $10 billion, according to the report. That year, data centers in the region produced a little over $700 million in state and local tax revenue. About 60 data centers operate in the Houston area.

Watchdog group warns of tax breaks’ danger to state budgets

On the other side of the debate over tax breaks for data centers, a report released last year by Good Jobs First, a nonprofit, nonpartisan watchdog group that tracks economic development incentives, decries the tax breaks as dangerous to state budgets.

“We know of no other form of state spending that is so out of control. Therefore, we recommend that states cancel their data center tax exemptions,” says Good Jobs research analyst Kasia Tarczynska, co-author of the report. “Shy of that, states should amend … legislation to cap how much any facility and company can avoid paying in taxes each year.”
