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.”

TotalEnergies powers up its largest utility-scale solar farms in Texas

ready to shine

TotalEnergies has begun the commercial operations of two utility-scale solar farms with integrated battery storage located in southeast Texas.

The two farms are located in Cottonwood and Danish Fields, which is TotalEnergies’ largest solar farm in the United States.

“The start-ups of Danish Fields and Cottonwood in the fast-growing ERCOT market showcase TotalEnergies’ ability to deliver competitive renewable electricity to support our clients’ decarbonization goals, as well as our own,” Olivier Jouny, senior vice president of renewables at TotalEnergies, says in a news release.

The new projects have a combined capacity of 1.2 gigawatts. They are part of a portfolio of renewable assets totaling 4 gigawatts in operation or under construction currently in Texas. Danish Fields holds a capacity of 720 megawatts peak and 1.4 million ground-mounted photovoltaic panels.

Cottonwood, with a capacity of 455 megawatts peak featuring over 847,000 ground-mounted photovoltaic panels, will also feature 225 megawatt hours of battery storage supplied by Saft. This is scheduled for commissioning in 2025. The electricity production is contracted under long-term PPAs indexed to “merchant prices through an upside-sharing mechanism with LyondellBasell and Saint-Gobain,” per thenews release. The deal is to help support the companies’ decarbonization efforts.

Seventy percent of Danish’s solar capacity has been contracted through long-term Corporate Power Purchase Agreements signed with Saint-Gobain, which feature an upside sharing mechanism indexed on merchant price. The other 30 percent is intended to support the decarbonization of TotalEnergies’ industrial plants in the Gulf Coast region. The projects will cover the electricity consumption of TotalEnergies’ industrial sites in Port Arthur and La Porte in Texas, and Carville in Louisiana, which include Myrtle Solar that was commissioned in 2023 and the under-construction Hill 1 solar farm.

In addition to the solar farms, TotalEnergies has also added 1.5 gigawatt of flexible power production capacity with three gas-fired power plants they acquired in Texas.

“Thanks to these projects, we are delighted to take another step in delivering our strategy across the entire value chain, from power generation to customer delivery, in order to achieve our profitability target of 12 (percent return on average capital employed) in our Integrated Power business,” Jouny adds in the release.

Houston's PowerBridge partners on 2GW Texas AI data center campus

data center venture

Houston-based PowerBridge has formed a joint venture with Denver-based Liberty Energy to develop large-scale data center campuses.

The joint venture’s initial focus will be PowerBridge’s Alpha Digital Campus, a 2-gigawatt data center operation planned for West Texas. PowerBridge sets up data center campuses to support AI and cloud computing. Liberty is an energy company whose Liberty Power Innovations subsidiary offers distributed power and energy storage services.

Houston-based investment firm Five Point Infrastructure LLC established PowerBridge last year, committing up to $1 billion in equity. Earlier this month, The Wall Street Journal reported Five Point is trying to raise $2.5 billion for a new fund targeting water management projects, natural gas treatment systems and data center sites.

Through Five Point subsidiary LandBridge, PowerBridge enjoys access to more than 275,000 acres for infrastructure development as well as low-cost natural gas.

The first phase of PowerBridge’s West Texas campus is expected to offer more than 300 megawatts of generation capacity, with the potential to add more capacity over time. The campus is scheduled to start delivering power in the fourth quarter of 2027.

“By aligning our powered-campus development assets with Liberty’s comprehensive power services and operational expertise, we are creating a model that can be scaled across future gigawatt-scale powered data center campuses in West Texas,” Alex Hernandez, founder and CEO of PowerBridge, said in a release.

Before joining PowerBridge in 2025, Hernandez led Cumulus Data and Talen Energy Corp., a provider of power and energy infrastructure. Amazon Web Services bought Cumulus Data, a subsidiary of Houston-based Talen, in 2024 for $650 million. Cumulus develops nuclear-powered data centers.

Hernandez sits on the board of the Electric Reliability Council of Texas (ERCOT), which manages about 90 percent of the state’s electrical load.

Liberty recently announced a partnership with Houston-based energy technology company SLB to support the expansion of data center capacity.

Energy AI startup chooses Houston for first U.S. office after $20M raise

welcome to houston

London-based AI firm Applied Computing has announced a $20 million Series A round and a new office in Houston.

The new Bayou City office is Applied Computing’s first in the United States and part of its North American expansion. The company is known for its Orbital AI platform, which is tailored for energy operations.

The funding round was led by Houston-based KBR Inc., with participation from San Francisco-based Databricks Ventures. KBR’s investment was first announced in March.

KBR and Applied Computing have also entered into a multi-year agreement to deliver exclusive AI products for the energy sector. KBR already has integrated Orbital into its INSITE 3.0 platform for energy projects, and is also using the product for ammonia production.

Applied Computing’s Orbital platform combines physics-grounded intelligence with models across chemical engineering, time-series forecasting and language, according to the company. The system analyzes sensor readings and can recognize a facility’s equipment constraints and operator activity. The platform can also allow technicians to run simulations of how a change to a facility could affect the rest of its operations.

According to TechCrunch, Applied Computing will use the $20 million to further explore projects and deployments with the energy sector, hire engineering and research positions, and continue to expand internationally, potentially into the Middle East.

The company is also working on deals with a major U.S. stream operator, TechCrunch reports. And Applied Computing shared on LinkedIn that it plans to announce its first partnership with a major European oil company in the coming weeks.

“Yesterday we showed Orbital live in deployments at our demo day at the Energy Institute in London,” Callum Adamson, CEO and co-founder of Applied Computing, posted on LinkedIn on July 16. “Today, we're announcing the capital to scale it globally as well as the launch of our new offices in Houston and Bangalore. In the weeks following, there will be more announcements on our progress, partnerships and deployments.”

The company opened its Bangalore offices in December.

Automakers enter the energy space with vehicles offering backup power

Power Boost

Winter Storm Uri, the multiday freeze that slammed Texas in February 2021 and pummeled the state's power grid, has been on Kenneth Kovar's mind ever since. Though the resident of New Braunfels didn't lose power at the time, he wasn't able to run his septic tank — it is independent from local systems. He had to fill his toilets with water from his backyard pool.

So when Kovar, 64, bought a Ford F-150 last fall, his hope was to be better prepared for any new crisis.

“I was interested in trying to find some sort of power backup situation,” he said.

Now, Kovar has a setup from Ford that allows drivers of certain F-150 models to plug their vehicle directly into their electric meter to power parts of their home during an outage.

It is the latest example of automakers broadly adapting their electrification technologies to the home energy business, especially as demand on the grid increases and sales of electric vehicles slow. Car companies are looking to leverage their multibillion dollar EV investments to tap into a promising market in vehicle, home and grid technology, both for backup power and for supporting electrical grid resiliency.

“They’re trying to look for other businesses that they might sell into,” said Parth Vaishnav, assistant professor of sustainable systems at the University of Michigan.

Ford's latest connects F-150 drivers to their meter

Drivers of the F-150 PowerBoost hybrid and F-150 Lightning electric pickup trucks can now plug in a one-foot long adapter to a 240-volt outlet onboard. That adapter — which Ford made with company Global Power Products — makes the vehicle compatible to plug into a longer, separate cable. That cable connects to a transfer switch installed directly on one's electric meter.

Through the adapter and cable series, homeowners can connect their vehicle essentially right to their home’s breaker box. The homeowner simply turns on and off which breaker switches they want for which devices they want powered.

“The way we think about it, especially for customers who already have a compatible vehicle is, you already own the power source, it’s in your driveway,” said Amanda Roraff, Ford's grid and energy services business acceleration lead.

The Lightning might provide power for two to three days, depending on what home devices are being used, and the PowerBoost Hybrid, up to five days on a single tank of gas.

The automaker says its solution is a less expensive way to supply backup power. Conventional, diesel-powered portable generators and full-home standby setups require expensive installation, costing several thousands of dollars. This solution, which also requires professional installation at the meter, starts around $1,100.

The setup only applies to about 200,000 vehicles so far, and it is also exclusively for outages. Ford also offers its Home Integration System for bidirectionality, sending power both from the vehicle to the home and from the home to the vehicle, while also being able to feed the grid.

Other automakers are boosting their energy solutions

Over 630,000 U.S. vehicles already have this functionality, estimates say, and automakers are rapidly expanding their available options with the goal of full vehicle-to-grid support in the long run.

South Korean auto brand Kia and Wallbox, an EV charging company, have teamed up so that drivers of eligible compatible vehicles can have home power backup during outages or during periods of high demand, to cut their utility use. They can send power back to the grid.

Tesla’s technology is similar — allowing drivers of equipped vehicles to connect to their home using additional Tesla hardware. The Cybertruck provides full vehicle-to-home capability, where other Tesla models can only connect to and power specific devices or appliances.

General Motors is also in the energy space.

A recent partnership with WeaveGrid, for instance, allows homeowners who drive certain GM EVs — and have the automaker’s home system and a proper grid interconnection — to enroll in some grid reliability utility programs. Once an outage is detected, GM’s vehicle-to-home tech has the capability to disconnect one's home from the grid and start supplying power from their GM EV.

“If you can imagine the future as we go forward, it's having the ability — now that we have this single platform — that allows our customer to experience our system,” said Wade Sheffer, vice president of GM energy, “but also can have the full control of the energy.”

The capability is an important lifeline amid EV sales slowdown

Not only is this business critical amid growing grid demand and increasing power outages, experts say automakers need to pivot with the EV market less active under current U.S. federal policy. Pure EV sales in the U.S. year-over-year are down 23.8%, according to a July Cox Automotive report on the first half of 2026. This demonstrates what an asset that EV and hybrid ownership can be.

The tech is not without challenges.

On the industry side, these systems have to undergo third-party testing to ensure they meet safety standards, and the vehicle and the charger need to be programmed to communicate. It also requires the approval of the utility where the capability is being used. It could take years to get an interconnect agreement.

On the customer side, homeowners need to understand their vehicles' abilities and how to self-manage their system. It also just brings another generator of power into the home mix.

Still, experts see opportunity, especially with interest in EV sales high outside of the U.S.

“We already know during an outage, its impact, providing electricity to the home,” said Scott Samuelsen, engineering professor emeritus at the University of California, Irvine. “This is going to become very, very popular.”
