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.

Harris County officials seek more local control over data centers

data demands

Three Harris County officials are pushing for greater local control over the development and operation of data centers.

County Attorney Abby Kamin, County Commissioner Lesley Briones and County Commissioner Adrian Garcia recently called for action to give Harris County more power to regulate data centers.

As it stands now, Harris County “has little to no authority” over the construction of data centers, Briones said at a news conference. Harris County has 55 operating, under-construction, or planned data centers, according to a document filed with the county.

Briones outlined four steps being included in the Harris County commissioners’ exploration of potentially tighter local regulation of data centers:

Reviewing what Harris County can and cannot do regarding data centers
Creating a Harris County plan for the upcoming state legislative session aimed at granting more local control over data center construction and operations. State lawmakers would need to approve any changes in local control.
Establishing community “listening” sessions in Harris County about data centers
Notifying Harris County commissioners when a proposed data center seeks permits

Kamin noted Houston and Harris County lack zoning regulations, and the county’s 34 cities set their own zoning rules. Furthermore, she said, Texas Attorney General Ken Paxton has not issued a ruling on whether counties can impose a moratorium on development of data centers.

However, she said, “limited jurisdiction does not mean limited responsibility … New technology is arriving in our communities faster than our laws and institutions can keep up with, whether that’s data centers, AI or even drones.”

The effort by Kamin, Briones, and Garcia follows Gov. Greg Abbott’s recent statewide halt of new environmental and construction permits for data centers. State permitting is frozen until the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas complete their review of data centers.

Their initiative also comes amid growing public concern over the amount of electricity and water gobbled up by data centers, as well as residents’ own rising electric and water bills.

Houston-based CenterPoint Energy expects to connect 8 gigawatts of new data-center loads in the Houston area by 2029, with about 4 gigawatts to follow, Kamin said. That, she said, would significantly increase peak power demand.

“No industry should get to monopolize or run roughshod over residents, public safety, and our critical natural resources,” Kamin said.

That being said, Kamin and Briones stressed they take pride in Houston being the Energy Capital of the World and Texas being an economic powerhouse.

“This isn’t about being against technology or new technology, but growth has to go hand in hand with accountability,” Kamin said.

Garcia said he’s open to welcoming data centers as good corporate neighbors, but not without protecting the people who live near these projects.

“I’ll keep an open mind,” he said, “but I want to know what will ultimately be the benefit to the community. And right now, I need tools [to do that].”

Houston bio-based materials co. steps into new sustainable consumer products

a cleaner shoe

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.

Houston solar manufacturer expands facility, production capacity

houston expansion

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.
