Led by Conroe-based Hertha Metals, five organizations in the Houston area earned shoutouts on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.

Geothermal exec on Houston expansion, commercialization and more

Q&A

Challenges in the energy transition often center around two questions: Where will organizations find the resources? And how will projects be financed?

XGS Energy's next-gen closed-loop geothermal well architecture addresses both issues head-on. The California-based company saw massive growth in the Houston market last year and recently completed a 100-meter field demonstration in central Texas, marking a major milestone for its technology's commercialization and potential for scale.

In an interview with EnergyCapital, Axel-Pierre Bois, XGS's Chief Technology Officer, shares what drew him to the geothermal space, why XGS is expanding in Houston and what the company's plans are for the year ahead.

How does XGS Energy's technology address the biggest challenges in geothermal energy?

XGS Energy is developing a geothermal system that decouples geothermal energy from its traditional dependence on water and geology to deliver affordable, clean energy anywhere there is hot rock.

Historically, geothermal resources have been hard to locate, as conventional systems require the overlap of hot rock, porous and permeable geology, and abundant water to produce energy, limiting their potential to a few select hot spots worldwide. Instead of relying on an underground fracture network that drives the geology and water requirements, the base component of XGS’s system is a single well, in which fluid is pumped to a hot rock resource and then returned to the surface through a tube-in-shell design, creating a sealed, closed loop. This allows XGS to produce geothermal energy anywhere where there is hot rock, unlocking terawatt-scale potential in the U.S. alone.

Geothermal systems have also struggled to secure project financing, as many systems have historically faced high levels of unplanned cost risk due to factors including water loss and production uncertainty. XGS’s sealed, closed-loop system ensures that it can provide reliable, predictable electricity throughout its lifespan. XGS also boosts the cost-competitiveness of its system through our major innovation, a proprietary thermally conductive materials system that is installed downhole around each well, increasing the heat transferred to the closed-loop system by 30-50%.

What has drawn you to a career in the geothermal energy space?

I have been in the subsurface industry for over 30 years, developing technical solutions for companies in the fields of geosciences, underground storage, upstream oil and gas, and geothermal heat harvesting to help improve their overall economic, ethical and environmental footprints. In 2009, I founded Curistec, a technology company providing research, engineering and technical services for geomechanics, wellbore integrity, well abandonment, cement design and cement and rock testing. A few years back, Curistec assisted with the Iceland Deep Drilling Project, helping to develop cement formulations for superhot geothermal well applications to enable drilling in high-temperature environments. As I looked toward the future, it became clear that next-generation geothermal technologies would transform the geothermal energy industry and open new markets worldwide. Curistec had been working closely with the XGS Energy team as technology partners for several years, so joining the team directly to help shape the technology development was an exciting opportunity to help develop and deploy a new system to unlock the full terawatt-scale potential of geothermal energy.

Tell us about the 100-meter field demonstration in central Texas completed in 2024 — what all did you and your team learn from the test?

Our 100-meter field demonstration in central Texas marked a significant step in our progress toward deploying geothermal energy in a commercial setting. With this field operation, we successfully demonstrated our ability to mix, pump and place our thermally conductive materials system at a commercial scale, using off-shelf tools and technologies. This was a significant milestone, taking us from theoretical models and laboratory tests to field-scale operations, proving that our novel geothermal system is operationally viable in real-world well conditions.

The completion of the Texas field demonstration advanced XGS into the new wave of geothermal innovators that are putting real steel in the ground. In 2024, we kicked off construction at our commercial-scale demonstration in California and are excited to share updates in the year ahead.

Last year, XGS Energy leased over 10,000 square feet of office space in Memorial City. How has Houston's business community and opportunities benefitted the company?

Houston, the epicenter of the oil and gas industry, has become a hub of energy innovation, offering attractive incentives for growing companies like XGS. The region’s workforce, which is home to some of the best subsurface engineers and operational talent in the energy sector, was a key factor for XGS when we were planning our operational roadmap. This expertise, paired with proximity to our partners in the field services industries, like cementing and drilling, is both a practical and tactical advantage for XGS.

We’ve built a strong technical and operational team here at XGS, with experience from the oil and gas industry, utilities and power project developers. XGS is planning for continued growth in the Houston area, leveraging the region’s leading engineering and operational workforce and its intensifying interest in supporting the energy transition.

What are XGS Energy's goals for 2025?

In 2024, the XGS Energy team made significant progress toward our goal of providing clean, round-the-clock energy with our solid-state geothermal system. In 2025, XGS Energy will be focused on deploying its geothermal system at a commercial scale, starting with the completion of our full-scale prototype in California. XGS will also continue accelerating our commercial traction, expanding our already robust and highly differentiated geothermal resource evaluation toolkit, advancing our global project pipeline, and growing our team to strengthen our operational capability and capacity.

TotalEnergies $1B payout shows evolution in Trump's anti-wind strategy

Shift in the Winds

The Trump administration’s $1 billion payout to TotalEnergies to walk away from U.S. offshore wind development is a novel tactic against the industry that supporters see as creative — but opponents see as foolish and extreme.

The Interior Department announced March 23 that TotalEnergies agreed to what is essentially a refund of its leases for projects off the coasts of North Carolina and New York, and will invest the money in a liquefied natural gas export terminal in Texas and other fossil fuel projects instead. The department hailed it as an “innovative agreement” with the French energy giant so that the "American people will no longer pay for ideological subsidies that benefited only the unreliable and costly offshore wind industry.”

The tactical shift comes after federal courts have thwarted President Donald Trump's efforts to stop offshore wind through executive action.

U.S. Sen. Chuck Schumer, a New York Democrat, told The Associated Press that the payment “sets a dangerous precedent and is a shortsighted misuse of taxpayer dollars.”

Robin Shaffer, president of the anti-offshore wind group Protect Our Coast New Jersey, applauded what he called “out of the box” thinking. Shaffer said after losing in the courts, the administration needed a way to take back leases that never should have been issued because of the harm offshore wind development causes to the marine environment.

“The Trump administration has been relentlessly creative in its efforts to stop offshore wind development in the U.S.," he said.

While the Republican president has been particularly hostile to offshore wind, he has also blocked dozens of clean energy projects and canceled billions of dollars in grants to promote clean energy, which he derides as the “Green New Scam.” This comes at a time when the U.S. is trying to boost power supplies in an artificial intelligence race against China and keep electricity bills from rising even higher.

The Iran war has also dealt a massive energy shock to the global economy by choking off most exports of crude oil and liquefied natural gas through the Strait of Hormuz.

A vow to stop offshore wind

On the campaign trail, Trump vowed to end the offshore wind industry as soon as he returned to the White House. Trump said wind turbines are horrible and expensive and pose a threat to birds and other wildlife.

Connecticut is getting power from Revolution Wind, an offshore wind project, and estimates it will lower wholesale energy costs for the state. The National Audubon Society, which is dedicated to the conservation of birds, has said climate change is a greater threat to birds.

Trump has long opposed offshore wind energy. In 2015, he lost his yearslong battle to stop an offshore wind farm near Aberdeen in eastern Scotland when Britain’s Supreme Court unanimously ruled against him. Trump claimed the 11 turbines would spoil the view from his golf course.

He wants to boost production of oil, natural gas and coal, which cause climate change, because he argues that doing so would give the U.S. the lowest-cost energy and electricity of any nation in the world.

His first day back in office, he acted on his campaign promise, signing an executive order temporarily halting offshore wind lease sales in federal waters and pausing permitting for all wind projects.

The deal comes after the administration is thwarted by the courts

U.S. District Judge Patti Saris vacated Trump’s executive order blocking wind energy projects on Dec. 8, declaring it unlawful as she sided with state attorneys general from 17 states and Washington, D.C., who challenged the order. The administration is appealing.

Two weeks later, the administration ordered that construction stop on five major East Coast offshore wind projects, citing national security concerns. Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government didn't show that the national security risk was so imminent that construction must halt.

TotalEnergies wasn't one of those; it had already paused its two projects soon after Trump was elected. And the company has now pledged not to develop any new offshore wind projects in the United States. CEO Patrick Pouyanné said the refunded lease fees will finance the construction of a liquefied natural gas plant in Texas and the development of its oil and gas activities, calling it a “more efficient use of capital” in the U.S.

Kit Kennedy, who directs the power division at the Natural Resources Defense Council, said the proposed payment to TotalEnergies was a “boondoggle” that “transfers nearly $1 billion from American taxpayers to a foreign corporation and the oil and gas industry.”

Why is the U.S. using taxpayer dollars “to not develop power when we need energy?” she asked, calling the Trump administration deal a “scam” and harmful to the U.S. economy and environment.

Carl Tobias, a University of Richmond Law School professor who has been following the lawsuits, called it “unorthodox.”

Democrats criticize stopping offshore wind when energy prices are spiking

As crude oil and gasoline prices surge, Democrats in Virginia said the U.S. should be strengthening its energy independence and resilience. Virginia started receiving power on March 23 from an offshore wind project targeted by Trump.

“Giving an energy company $1 billion of taxpayer money to pack up its jobs and invest elsewhere — in the middle of an unpopular and unwise war that is spiking energy costs — is beyond idiotic,” U.S. Sen. Tim Kaine said in a statement to AP.

U.S. Rep. Chellie Pingree, a Maine Democrat, questioned whether the payout is legal under appropriations law and said she would question Interior Secretary Doug Burgum about it at the upcoming budget hearings.

Dozens of commercial leases issued by the Bureau of Ocean Energy Management remain active for wind energy development in the U.S.

Abigail Dillen, president of Earthjustice, said she wouldn't attempt to guess whether the Trump administration will pay to stop any others, but clearly it is willing to go to extreme measures.

“Will they do this again? Maybe,” she said.

TotalEnergies strikes $1B federal deal to exit offshore wind sector

canceled projects

TotalEnergies, a French company whose U.S. headquarters is in Houston, has agreed to redirect nearly $930 million in capital from two offshore wind leases on the East Coast to oil, natural gas and liquefied natural gas (LNG) production.

In its agreement with the U.S. Department of the Interior, TotalEnergies has also promised not to develop new offshore wind projects in the U.S. “in light of national security concerns,” according to a department press release.

Federal agency hails ‘landmark agreement’

The Department of the Interior called the deal a “landmark agreement” that will steer capital “from expensive, unreliable offshore wind leases toward affordable, reliable natural gas projects that will provide secure energy for hardworking Americans.”

Renewable energy advocates object to what they believe is the Trump administration’s mischaracterization of offshore wind projects.

Under the Department of the Interior agreement, the federal government will reimburse TotalEnergies on a dollar-for-dollar basis for the leases, up to the amount that the energy company paid.

“Offshore wind is one of the most expensive, unreliable, environmentally disruptive, and subsidy-dependent schemes ever forced on American ratepayers and taxpayers,” Interior Secretary Doug Burgum said in the announcement. “We welcome TotalEnergies’ commitment to developing projects that produce dependable, affordable power to lower Americans' monthly bills while providing secure U.S. baseload power today — and in the future.”

TotalEnergies cites U.S. policy in move away from U.S. wind power

In the news release, Patrick Pouyanné, chairman and CEO of TotalEnergies, says the company was “pleased” to sign the agreement to support the Trump administration’s energy policy.

“Considering that the development of offshore wind projects is not in the country’s interest, we have decided to renounce offshore wind development in the United States, in exchange for the reimbursement of the lease fees,” Pouyanné says.

TotalEnergies redirects capital to LNG, oil, and natural gas

TotalEnergies will use the $928 million it spent on the offshore wind leases for development of a joint venture LNG plant in the Rio Grande Valley, as well as for production of upstream oil in the Gulf of Mexico and for production of shale gas.

“These investments will contribute to supplying Europe with much-needed LNG from the U.S. and provide gas for U.S. data center development. We believe this is a more efficient use of capital in the United States,” Pouyanné says.

TotalEnergies paid $133.3 million for an offshore wind lease at the Carolina Long Bay project off the coast of North Carolina and $795 million in 2022 for a lease covering a 1,545-megawatt commercial offshore wind facility off the coast of New Jersey.

“TotalEnergies’ studies on these leases have shown that offshore wind developments in the United States, unlike those in Europe, are costly and might have a negative impact on power affordability for U.S. consumers,” TotalEnergies said in a company-issued press release. “Since other technologies are available to meet the growing demand for electricity in the United States in a more affordable way, TotalEnergies considers there is no need to allocate capital to this technology in the U.S.”

Since 2022, TotalEnergies has invested nearly $12 billion to promote the development of oil, LNG, and electricity in the U.S. In 2025, TotalEnergies was the No. 1 exporter of LNG from the U.S.

Industry groups push back on offshore wind pullback

The American Clean Energy Association has pushed back on the Trump administration’s characterization of offshore wind projects.

“The offshore wind industry creates thousands of high-quality, good-paying jobs, and is revitalizing American manufacturing supply chains and U.S. shipyards,” Jason Grumet, the association’s CEO, said in December after the Trump administration paused all leases for large-scale offshore wind projects under construction in the U.S. “It is a critical component of our energy security and provides stable, domestic power that helps meet demand and keep costs low.”

Grumet added that President Trump’s “relentless attacks on offshore wind undermine his own economic agenda and needlessly harm American workers and consumers.” He called for passage of federal legislation that would prevent the White House “from picking winners and losers” in the energy sector and “placing political ideology” above Americans’ best interests.

The National Resources Defense Council offered a similar response to the offshore wind leases being paused.

“In its ongoing effort to prop up waning fossil fuels interests, the administration is taking wilder and wilder swings at the clean energy projects this economy needs,” said Pasha Feinberg, the council’s offshore wind strategist. “Investments in energy infrastructure require business certainty. This is the opposite. If the administration thinks the chilling impacts of this action are limited to the clean energy sector, it is sorely mistaken.”
