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.”

DOE announces geothermal initiative, community-focused pilot at Houston energy conference

keynote address

The Department of Energy announced two major initiatives at U.S. Secretary of Energy Jennifer M. Granholm's address earlier this week at CERAWeek by S&P Global.

The first announcement Granholm revealed on Monday, March 18, at her keynote address was the DOE's latest Pathways to Commercial Liftoff report, which are initiatives established to provide investors with information of how specific energy technologies commercialize and what challenges they each have to overcome as they scale.

"We develop these Liftoff Reports through a combination of modeling and hundreds and hundreds of interviews with people across the whole investment lifecycle—from early-stage capital to commercial banks and institutional investors," Granholm says in her address.

The DOE has released eight already, and the ninth — and Granholm's favorite, she says — is on geothermal energy.

"Geothermal has such enormous potential. If we can capture the 'heat beneath our feet,' it can be the clean, reliable, base-load scalable power for everybody from industries to households," she says.

Geothermal development requires similar skills and infrastructure to traditional oil and gas, meaning the transition should be smooth, she explains, adding that the market is huge for geothermal.

"At scale, this market is significant: We're talking about at least—at least—a $250 billion investment opportunity to meet the goal that we have of 90 gigawatts of capacity by 2050," she remarks.

Granholm's address shifted into acknowledging the negative impact on communities the energy industry's history is paved with. She emphasizes how each of the Biden Administration's laws passed — like the Inflation Reduction Act and the Bipartisan Infrastructure Law — implemented requirements and incentives with communities in mind.

The administration's next initiative, and Granholm's second big announcement, is "to empower communities to build their energy future."

Regional Energy Democracy Initiative, or REDI, as Granholm describes, will "bring together companies, and community groups, and academic institutions, and philanthropy to weave equity and justice into DOE-funded clean energy projects."

The inaugural pilot will be in the Gulf South across Texas and Louisiana. She says the DOE plans to award over $8 billion to regional carbon reduction and clean energy infrastructure projects.

"These structures will provide capacity building, technical assistance to help communities match their most pressing needs with the biggest opportunities…to design and to implement Community Benefits Plans," Granholm says, "in short, really to have a say in how the historic clean energy investments in their backyards are going to benefit their people."

Granholm also noted on the progress of the clean energy sector, including how clean energy investment is three times what it was in 2018 and that in 2024, wind and solar energy in the U.S. is expected to outpace coal generation for the first time.

All this progress, Granholm explains, in light of global events and global energy supply disruption

"But our work together really has to extend beyond crisis management," she says. "Because the sooner that we acknowledge this transition for what it is—an undeniable, inevitable, and necessary realignment of the world’s energy system—the sooner we can capitalize on this incredible opportunity."

Houston-area counties land DOE funding for energy infrastructure projects

seeing green

The U.S. Department of Energy recently awarded more than $2 million to Harris and Montgomery counties for projects that improve energy efficiency and infrastructure in the region.

The funds come from the DOE's Energy Efficiency and Conservation Block Grant (EECBG) Program. Harris and Montgomery counties are among 28 state, local, and Tribal governments to have been awarded a total of $30 million through the initiative, according to a statement.

The grants were awarded to eight states, four cities, four counties and 12 smaller, rural communities.

“Our local governments are at the forefront of our clean energy revolution and are critical touchpoints with our nation’s communities creating clean, healthy and affordable communities,” U.S. Secretary of Energy Jennifer M. Granholm says in a statement. “With historic funding thanks to President Biden’s clean energy laws, more Americans will receive upgrades to their homes through residential energy efficiency rebates, expanded weatherization efforts, and electrification programs that will save them energy and increase their comfort.

"This funding will also invest in improving public spaces, giving more Americans across the country access to energy efficient technologies and clean energy infrastructure in their communities such as heat pumps, LED lights, solar energy, and EV charging stations,” she continues.

Harris County was awarded $1.64 million, the largest total among the local governments. It will be put toward for several projects:

  • Conducting community engagement with disadvantaged communities for climate justice planning
  • Performing site assessments for solar and storage on county properties in disadvantaged communities
  • Conducting recycling pilots at county facilities
  • Enhancing walking and bicycling to school as part of the Safe Routes to School plan
  • Deploying an off-grid, solar EV station on county property in a disadvantaged community in the greater-Houston area

Montgomery County was awarded $457,580 to replace 150 metal halide lights at a community sports field with LED lights and add wireless controls.

According to the DOE, more than $430 million in formula grant funding is available through the EECBG Program and another 2,700 governments and tribes are eligible for funds. Grants are slated to be awarded on a rolling basis as the department receives applications. The application deadline for eligible local governments and tribes has been extended to April 30, 2024.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
