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.

TotalEnergies expands solar joint venture with $1.2B portfolio in Texas, Ohio

solar expansion

TotalEnergies, a French company whose U.S. headquarters is in Houston, announced this month that it is expanding its renewable energy joint venture with New York-based investment firm KKR by adding 700 megawatts of utility-scale solar projects.

The deal will add three utility-scale solar assets in Texas and Ohio, which are expected to reach commercial operation by Q1 2027, according to a news release from the company. The portfolio is valued at $1.2 billion.

The 50/50 joint venture between TotalEnergies and KKR currently holds 1.4 gigawatts of renewable energy and will grow to 2.1 gigawatts.

The new deal is expected to close this year. Once completed, TotalEnergies will operate the assets. The electricity generated from the solar projects will be sold to third parties, the company reports.

The companies originally formed the joint venture about a year ago when TotalEnergies sold KKR a 50 percent stake in a North American solar portfolio valued at $1.25 billion. The deal originally included six utility-scale solar assets, primarily located in the U.S.

“TotalEnergies is a renewable energy industry leader globally, and we are thrilled to establish this joint venture with the TotalEnergies team to support their renewables business," Cecilio Velasco, managing director KKR, said in a release last year. “We have long been investors in renewables through our infrastructure platform, having committed more than $23 billion to date in energy transition investments. TotalEnergies’ North American solar portfolio is a great fit for us, representing high-quality renewable energy assets with long term contracts.”

TotalEnergies reports that by June 2026 it held more than 37 gigawatts of gross renewable power generation capacity. It aims to achieve over 100 terawatt-hours of net electricity production by 2030.

The company signed a major power purchase agreement with Google earlier this year. Through the deal, TotalEnergies will supply the tech giant with 1 gigawatt of solar power for its data centers in Texas over a 15-year span.

However, the company also recently redirected nearly $1 billion in capital away from wind energy projects and "decided to renounce offshore wind development in the United States." Read more here.

Houston researchers develop compact carbon capture tech for data centers

AI emissions

Two scientists from the University of Houston have been experimenting with new carbon capture systems that fit inside a standard shipping container, which have the potential to make eliminating carbon output from industrial sites much easier.

The capture of industrial carbon is an important complement to the fight against climate change, as well as winning tax credits for businesses that use carbon capture technology.

The problem is that such systems are often measured in acres, making them expensive to build and extremely power-hungry to actually use. UH Engineering Professor Mim Rahimi and former UH Ph.D. student Ahmad Hassan (now a postdoctoral associate at Harvard) have managed to fit their new system, the Small Modular Electrochemical Container (SMECs), inside a standard 40-foot shipping crate, making them compact and modular enough to be installed almost anywhere for operations of all sizes. Their research was recently published in the journal Environmental Science & Technology.

“With a conventional system, you’re building a 130-foot-tall structure designed for a specific power plant. With our technology, we can adjust the capacity by simply turning containers on or off,” Rahimi said in a news release. “That flexibility is particularly important for data centers, where electricity can come from a combination of natural gas and renewable sources.”

Rahimi and Hassan used simulated gas models to show that under optimal conditions, the SMEC used electrochemically mediated amine regeneration (EMAR) cells developed in Rahimi’s lab to capture 90 percent of carbon under optimal conditions through 300 cycles over 50 hours.

Encouraged, the team then modeled a 360-megawatt natural gas power plant associated with OpenAI’s Stargate AI data center project in Abilene, Texas. In addition to the savings on infrastructure costs, 20 of the researchers’ shipping container systems were able to capture 98 percent of carbon from Stargate’s 875-acre campus based on the model.

The looming energy costs and subsequent carbon emissions from data centers are a real concern. Estimates from the U.S. Department of Energy hypothesize that 12 percent of America’s energy needs could be gobbled up by the centers as soon as 2028. That is a massive new source of carbon. The flexibility of the SMEC means they can be deployed wherever the centers spring up.

“We’re taking a technology that traditionally requires enormous infrastructure and finding a way to fit it inside a shipping container,” Rahimi added in the release. “That opens up entirely new possibilities for how and where carbon capture systems can be used.”

In the future, the researchers say they plan to look at ways to adapt the technology to capture carbon dioxide directly from the atmosphere.

Hertha Metals breaks ground on $100M high-purity iron factory in Conroe

coming soon

Shortly after announcing a $133.65 Series A funding round, Conroe-based Hertha Metals broke ground Oct. 8 on a $100 million factory that will produce steel-grade and magnet-grade high-purity iron.

Hertha’s Chalyx plant, located in Conroe, will manufacture a total of about 10,000 metric tons per year of magnet-grade and steel-grade high-purity iron. The factory will use Hertha’s single-step process to generate high-purity iron for rare-earth-magnet and steel manufacturers in the U.S.

Hertha says Chalyx will be the first U.S. commercial plant for production of magnet-grade high-purity iron.

Chalyx is being built next to Hertha’s headquarters and its Pi100 pilot plant, which will remain in operation. Chalyx and Pi100 will form the first modern-day iron and steel “innovation complex” in the U.S., the company says.

“I founded Hertha Metals because I believed we could significantly improve how the world makes iron and steel from ore, and that an industry so fundamental to our future still had enormous room for invention,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

The 4-year-old startup says the Chalyx complex will lay the foundation for its first 500,000-ton-per-year steel mill.

Chalyx’s first priority is making high-purity iron for U.S. manufacturers of rare-earth magnets, Hertha says. These magnets are critical components for electric vehicles, data centers, wind turbines and defense systems.

China produces an estimated 94 percent of high-purity iron for rare-earth magnets, according to Hertha.

Aside from iron for rare-earth magnets, Chalyx will make iron and steel for pilot projects in the steel industry.

The plant is expected to come online in late 2027, with production of magnet-grade high-purity iron starting in early 2028.

Today, Hertha employs 32 people, the company says. Once it’s fully operating, the Chalyx plant will employ about 50 people.

Just ahead of the groundbreaking, Hertha announced the $133.65 million Series A round, co-led by Khosla Ventures and Doerr Capital. The round included a $65 million equity investment from the Pentagon.

“Iron and steel have shaped human progress for thousands of years. And I believe there is still an enormous amount left to invent,” Meroueh said at the groundbreaking ceremony.
