Researchers from the University of Houston — along with a Hawaiian company — have received $3.3 million in funding to explore artificial intelligence-backed subsurface sensing system for safe and efficient underground power line installation.

Houston's power lines are above ground, but studies show underground power is more reliable. Installing underground power lines is costly and disruptive, but the U.S. Department of Energy, in an effort to find a solution, has put $34 million into its new GOPHURRS program, which stands for Grid Overhaul with Proactive, High-speed Undergrounding for Reliability, Resilience, and Security. The funding has been distributed across 12 projects in 11 states.

“Modernizing our nation’s power grid is essential to building a clean energy future that lowers energy costs for working Americans and strengthens our national security,” U.S. Secretary of Energy Jennifer M. Granholm says in a DOE press release.

UH and Hawaii-based Oceanit are behind one of the funded projects, entitled “Artificial Intelligence and Unmanned Aerial Vehicle Real-Time Advanced Look-Ahead Subsurface Sensor.”

The researchers are looking a developing a subsurface sensing system for underground power line installation, potentially using machine learning, electromagnetic resistivity well logging, and drone technology to predict and sense obstacles to installation.

Jiefu Chen, associate professor of electrical and computer engineering at UH, is a key collaborator on the project, focused on electromagnetic antennas installed on UAV and HDD drilling string. He's working with Yueqin Huang, assistant professor of information science technology, who leads the geophysical signal processing and Xuqing Wu, associate professor of computer information systems, responsible for integrating machine learning.

“Advanced subsurface sensing and characterization technologies are essential for the undergrounding of power lines,” says Chen in the release. “This initiative can enhance the grid's resilience against natural hazards such as wildfires and hurricanes.”

“If proven successful, our proposed look-ahead subsurface sensing system could significantly reduce the costs of horizontal directional drilling for installing underground utilities,” Chen continues. “Promoting HDD offers environmental advantages over traditional trenching methods and enhances the power grid’s resilience.”

Why this entrepreneur sees a bright future for hydrogen innovation Houston's energy transition ecosystem

Q&A

While Patrick Sullivan lives on an island almost 4,000 miles away from Houston, the entrepreneur is no stranger to Houston's energy ecosystem.

Oceanit, founded in 1985 by Sullivan, is based in Hawaii, a portion of its customer base is based right here in Houston. Additionally, he opened his company's H2XCEL lab locally earlier this year.

“We are, indeed, in the middle of the sea, but we work around the world,” Sullivan, who serves as president and CEO of his company, says on the Houston Innovators Podcast. “What we do in Houston is interesting because we consider Houston the center of energy. And energy makes the world go around, and there’s just no two ways around it. Of course, there’s lots of transition going on, so it’s an exciting time to be doing energy.”

Learn more about Oceanit's presence in Houston and the impact the company is having on the energy transition in the podcast as well as the excerpt below.

EnergyCapital: What’s the opportunity you see with hydrogen?

Patrick Sullivan: The US has several millions of miles of methane pipelines, so if you start looking at loading hydrogen into those methane pipelines, you start displacing carbon. There are all sorts of interesting trade offs, but one of the challenges is this area called embrittlement. What that means is hydrogen is a little molecule, and when you put it next to a metal, sometimes it likes to hide in the metal, and over time, sometimes it builds up and then it can crack that metal. That’s called hydrogen embrittlement, and people are worried about that.

Turns out, we have developed a technology for a military application, and we can do things to metal without embrittlement. We’ve learned a lot over the years. We thought, what if we take what we’ve learned in the defense space and apply it to energy with the pipelines.

EC: What’s your goal with your new Houston-based H2XCEL lab that features your hydrogen embrittlement prevention technology?

PS: We can test those to failure right there in Houston. We’re talking to all the pipeline companies about getting their steel pipe and running through all these tests to show how it’s going to perform with all these different mixtures.

The idea is to get the community to see that when you integrate technology from different fields into the energy space, we can keep making progress.

It’s going to take time. But if we start reducing carbon and the use of fossil fuel today, we buy time for the planet.

EC: What’s the next big thing within tech that you’re working on?

PS: It’s a really interesting question, there’s so much going on right now, it’s really an exciting time in the tech space and the reason is because the world has been asleep at the switch for a while in terms of real technology.

One of the things we’ve put a lot of time and effort into is artificial intelligence. Large language models are definitely entertaining and have tons of opportunities. They’ve have got their pros and cons. We’ve worked with Noam Chomsky for years now, and our approach is based on Chomskyan grammar. The idea of human cognition is linguistic competency. When you speak, you’re mathematically efficient. It’s not random, it’s how human brains are put together. We built a system based on that hypothesis.

I think the reason AI is going to get more airtime too is the social and political consequences of misinformation.

New lab opens in Houston to help make pipelines safer for hydrogen transport

HOU-DRYGEN

An innovative Hawaii-based technology company is saying aloha to Houston with the opening of a unique test laboratory that aims to increase hydrogen pipeline safety. It is the latest sign that Houston is at the forefront of the movement to hydrogen energy.

The lab, H2XCEL — short for “Hydrogen Accelerator” — aims to integrate hydrogen into the current energy infrastructure, a serious cost-saver for companies looking to make the energy transition. Oceanit, a Honolulu-based technology company, is behind the lab.

H2XCEL will be the only lab in the U.S. capable of testing hydrogen and methane mixtures at high temperatures and pressures. Its aim is to protect pipelines from hydrogen embrittlement — when small hydrogen molecules penetrate pipe walls and damage the metal, potentially causing cracks, leaks, and failures.

“The launch of this testing facility is a major milestone. It is the only lab of its kind in the U.S. and the work underway at H2XCEL will accelerate the transition toward a hydrogen-driven economy,” Patrick Sullivan, the CEO and founder of Oceanit, says in a news release. “We see a toolset emerging that will enable the U.S. to accelerate toward a low-carbon future.”

Houston was the obvious choice to launch the new lab, says Oceanit’s Direct of Marketing James Andrews.

“Houston is the energy capital of the world," Andrews explains. "Oceanit knew that if we wanted to make inroads with decarbonization technologies, we needed to be physically present there.”

H2XCEL uses Oceanit’s HydroPel pipeline nanotechnology, developed with the support of the U.S. Department of Energy. It is a surface treatment that protects metals, eliminating the need to build new pipelines using expensive, hydrogen-resistant metals. The estimated cost of building new hydrogen pipelines is approximately $4.65 million per mile, according to a press release from the company. In contrast, HydroPel can be applied to existing pipelines to prevent damage, and the cost to refurbish one mile of existing steel pipeline is less than 10 percent of the cost per mile for new pipeline construction.

One of the main objectives of the new Houston lab will be to test hydrogen-methane blends under varying conditions to determine how to use HydroPel safely. By enabling the energy sector to reduce its climate impact while continuing to provide energy using existing infrastructure, methane-hydrogen blends capitalize on hydrogen’s carbon-free energy potential and its positive impact on climate change.

“We want to create a situation where we can speed up energy transition,” says Andrews. “By blending it into a safer environment, we can make it attractive to bigger players.”

Oceanit already has a Houston presence where the team is focused on several other technologies related to hydrogen, including HeatX, a water-based technology for heat transfer surfaces in refineries, power plants, and more, as well as their HALO system, which utilizes directed energy to produce clean hydrogen wastewater and other waste byproducts produced in industrial businesses.

A recent report issued by Rice University’s Baker Institute for Public Policy about the hydrogen economy

in Texas insists that the Lone Star State is an ideal hub for hydrogen as an energy source. The report explains that with the state’s existing oil and gas infrastructure, Texas is the best spot to affordably develop hydrogen while managing economic challenges. The Houston region already produces and consumes a third of the nation’s hydrogen, according to the report, and has more than 50 percent of the country’s dedicated hydrogen pipelines.

Houston’s Fervo Energy amasses $12B backlog of orders

q3 results

Houston-based geothermal power company Fervo Energy saw a 65 percent spike in purchase orders during the third quarter.

During Fervo’s third-quarter earnings call, Tim Latimer, co-founder, chair, president and CEO, said the company had a $11.9 billion backlog of orders, up from $7.2 billion in the previous quarter.

Those numbers didn’t translate to robust financial results in the third quarter, though. It closed the quarter with an operating loss of $43 million on revenue of just $116,000.

Beyond the billions of dollars in signed purchase agreements, Fervo is in talks with prospective customers in the utility, industrial data-center sectors, Latimer said. About half the potential customers are in the data-center sector, 35 percent in the utility sector and 15 percent in the industrial sector.

Latimer said the broad-based demand reflected by the backlog and the discussions with potential customers reinforces the critical need for reliable, readily available power.

“Our approach to power delivery will continue to blend front-of-the-meter and behind-the-meter development,” he said. “Grid-connected assets remain the foundation, though behind-the-meter gives customers a faster path to power when transmission time lines lag their need.”

Front-of-the-meter refers to power plants, utility-scale solar and wind farms, large grid batteries, and transmission and distribution infrastructure. Behind-the-meter assets sit on the customer side of the meter, such as backup generators and EV chargers at homes, businesses, factories and other everyday places.

The order backlog isn’t Fervo’s only recent milestone. In late September, the company’s Cape Station geothermal plant in Utah started delivering its first utility-scale geothermal power to the grid. The plant is producing about 33 megawatts of power.

Earlier in September, Fervo signed a 15-year deal to supply about 396 megawatts of power for Google data centers. The power will be delivered in four 99-megawatt batches. The company filed its $1.89 billion IPO this spring.

3 Houston incubators supporting hard tech, energy transition, and beyond

Meet The Finalists

It takes a village to launch a business. That's where Houston's network of incubators and accelerators can step in, providing the resources, mentorship and community needed to push a fledgling company forward.

As part of InnovationMap's 2026 Houston Innovation Awards, the Incubator/Accelerator of the Year category honors a local organization that is championing and fueling the growth of Houston startups.

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced in 2024, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its third Houston cohort this summer.

The two-year program graduated its first class of Houston fellows in 2026 and saw its first alumni IPO from Houston-based Fervo Energy, which previously participated in a Berkley cohort. Nationally, it has supported 346 fellows and 276 companies since 2015. Those companies have raised more than $6 billion in follow-on funding, according to Activate. In Houston, it has supported Houston startups like energy transition leaders Solidec and FlowCellutions. Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with members spanning 72 countries. Launched in 2018, Impact Hub Houston says its membership tripled by the beginning of 2026. This year brought major milestones for the community, including the launch of its Ideas to Impact Accelerator, which supported 11 founders across the health, education, food systems, civic technology and workforce development sectors. It also received funding from more than 20 international Impact Hubs to develop SYNC, a collaboration platform that 25 Impact Hubs across five continents have committed to pilot. The organization has worked with local startups including Myoviva Health, The Change Lab and INNERVERSE Inc.

MarMo Innovation

Galveston-based business incubator MarMo Innovation is focused on removing barriers to entrepreneurship. It aims to provide affordable space, education, mentorship, market access, connections and real-world opportunities that help entrepreneurs move from idea to launch to sustainable growth. The "industry-agnostic" incubator was founded in 2022 and is led by Executive Director Erica Delgadillo.

This year, the organization moved from primarily serving as a coworking and community space into a more comprehensive entrepreneurial incubator by expanding its MarMo Market, MarMo Market Jr. and Lunch LineUp programs. A major focus for MarMo is food entrepreneurship. It is developing an Incubator Kitchen, which MarMo says will support programs like its Cottage to Commercial Bootcamp and Food Biz 101. The organization also expanded its board this year and says it is diversifying its revenue through memberships, events, markets, equipment and space rentals, sponsorships, grants and new entrepreneurial programming.

Sage Geosystems taps Halliburton to advance Nevada geothermal project

power partnership

Houston-based Sage Geosystems has selected oil and gas powerhouse Halliburton to provide cementing and stimulation services at its enhanced geothermal project in Nevada known as Project Vector.

“Our technology and experience will support Sage as it advances its geopressured geothermal technology,” Shawn Skobel, vice president at Halliburton, said in a news release.

Halliburton will provide Sage with technical modeling, engineering design, and field execution support as part of its specialized cementing and stimulation services at Project Vector at Ormat Technologies' Blue Mountain geothermal power plant. Sage announced the location of the geothermal project in September.

At the time, Sage said it expected to begin drilling the first well at Project Vector this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

The project will use Sage’s enhanced geothermal systems (EGS) method in a two-well system to convert geothermal heat into electricity. The project aims to help meet industrial and residential demand, especially as data centers strain energy grids.

Founded in 2020, Sage has raised $159 million across three funding rounds. Its technology aims to reach Earth’s natural heat source deep underground for more consistent power generation and utilizes engineered subsurface reservoirs to minimize water and energy losses and increase net power output. Through the process, Sage says it can enable reliable, 24/7 power generation.

“One of the keys to scaling next-generation geothermal is combining innovative subsurface technology with the proven capabilities and execution of the oil and gas industry,” Jason Peart, Chief Operating Officer of Sage Geosystems, added in the news release. “Halliburton brings decades of experience in well integrity and reservoir stimulation, two critical components of our development approach. By selecting an established industry leader, we are strengthening our ability to execute Project Vector and demonstrate that Sage’s technology can be replicated and deployed commercially across a broad range of geologies.”

Sage is building off prior success of its South Texas SMECI facility, which began operations in August. Project Vector supports Sage’s growing commercial pipeline, which includes a 150-megawatt geothermal power agreement with Meta.
