Six Houston-area businesses appear on Time magazine’s 2026 list of the world’s top greentech companies, with a high-flying name leading the pack.

The highest-ranked local company is Houston-based geothermal power producer Fervo Energy, which claims the No. 4 spot—up from No. 14 last year.

In May, Fervo raised nearly $1.9 billion in its IPO, making it the biggest-ever IPO in the clean energy sector. The company’s valuation now exceeds $10 billion.

Founded in 2017, Fervo borrows methods from the oil and gas sector to drill wells that go down vertically into hot rock before turning horizontal, letting water circulate through them and produce electricity from the heat it absorbs. Cape Station in Utah, the company's first utility-scale project, is set to start delivering power to the grid later this year, with capacity expected to grow to 100 megawatts by 2027.

Co-founder and CEO Tim Latimer tells Fast Company, which named him a 2026 Visionary of the Year, that he launched his career as a drilling engineer for fossil fuels, “but quickly became obsessed with this idea that the drilling techniques we were using would actually be transformative for the world of geothermal as well.”

Fast Company notes the geothermal power generated by Cape Station will be available 24/7, unlike wind and solar power.

“When you start adding something to the grid mix that’s affordable and works around the clock,” Latimer says, “that’s going to be a huge asset to meeting our country’s energy needs.”

Time teamed up with data provider Statista to compile the second annual ranking of the 250 top greentech companies in the world. Companies on the list either develop or provide green technology, products, or services that help ease or reverse the environmental impacts of human activity.

Statista gathered and analyzed data from more than 8,300 companies to create the list, and they were scored in three categories: positive environmental impact, innovation, and financial strength. Fervo earned a score of 94.63 out of 100.

Joining Fervo on this year’s list are:

  • Houston-based Quaise Energy (No. 78), which specializes in terawatt-scale geothermal power
  • The Woodlands-based Plus Power (No. 112), which develops, owns and operates battery storage projects
  • Houston-based Utility Global (No. 167), which develops decarbonization technology
  • Houston-based 1PointFive (No. 217), an Occidental Petroleum subsidiary that offers large-scale carbon removal and storage.
  • Houston-based Sage Geosystems (No. 250), which produces commercial-scale geothermal power

Earlier this year, six Houston-area companies landed on Time's list of top greentech companies in America: Fervo (No. 1), Quaise Energy (No. 49), Plus Power (No. 71), Utility Global (No. 98), Solugen (No. 199) and Noodoe (No. 215).

Hertha Metals named world's  No. 1 most innovative manufacturing co. of 2026

top innovators

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.

Pioneering Houston professor earns prestigious 2025 Franklin Institute Award

medal winner

Rice University professor and nanoscience pioneer Naomi Halas has received the 2025 Benjamin Franklin Medal in Chemistry.

In addition to her role at Rice, Halas is co-founder and technical advisor of Syzygy Plasmonics, a Houston startup that relies on light instead of combustion as an energy source. This enables efficient, sustainable transformation of low-carbon ammonia into hydrogen when powered by renewable electricity.

Halas earned the Franklin Medal “for the creation and development of nanoshells — metal-coated nanoscale particles that can capture light energy — for use in many biomedical and chemical applications,” according to a release from Rice.

Halas’ work has pioneered insights into how light and matter interact at small scales, according to Rice. She joined Rice in 1989 to support the late Richard Smalley’s advancements in nanoscale science and technology.

“A lot of people were talking about nano like it was something completely new,” Halas said in the release. “But I realized it was really just chemistry viewed in a different way, and that really got me thinking about how I can combine the worlds of laser science and nanoscience.”

That shift in perspective led to the development of nanoparticles that spawned innovations in fields such as cancer therapy, water purification, and renewable energy.

“Naomi’s contributions to nanoscience have not only expanded the boundaries of our understanding but also transformed real-world applications in medicine, energy and beyond,” Rice President Reginald DesRoches added. “Her pioneering work on nanoshells exemplifies the spirit of innovation that defines Rice.”

One of Halas’ projects led to the founding of Syzygy, which develops light-driven, all-electric chemical reactors for inexpensive, sustainable production of hydrogen fuel. The company was named to was named to Fast Company's energy innovation list last year.

Halas is the first Rice faculty member to be elected to both the National Academy of Sciences and the National Academy of Engineering for research carried out at the university. She also has been elected to the National Academy of Inventors, the American Academy of Arts and Sciences, and the Royal Danish Academy of Science and Letters. Halas holds 30 patents in the fields of medicine, chemistry, physics and engineering.

The Franklin Medal is awarded by the Franklin Institute of Philadelphia. Many scientists who have received the award have gone on to win Nobel prizes.

As a recipient of the Franklin honor, Halas will receive a $10,000 honorarium and a 14-karat gold medal during an award ceremony May 1 in Philadelphia.

2 Houston cleantech companies rank on most innovative energy companies lists

getting recognized

A pair of Houston energy startups have been named among the 10 most innovative energy companies for 2024.

Fast Company magazine just placed Fervo Energy and Syzygy Plasmonics on its energy innovation list. In all, 606 companies and organizations across a variety of industries were recognized for “reshaping industries and culture.”

Fervo produces carbon-free geothermal energy. Its existing geothermal project is in Nevada, and it’s building a geothermal project in Utah. The company recently raised $244 million.

“Solar and wind are cheap, but they don’t provide the kind of always-on dispatchable electricity that hydropower, hydrogen, and nuclear do; even at current high prices, enhanced geothermal is still cheaper than those other sources,” Fast Company notes.

The Fast Company accolade comes shortly after Time and Statista named Fervo one of the top greentech companies for 2024.

By relying on light rather than combustion to generate chemical reactions, Syzygy is taking on the use of fossil fuels in the chemical industry, Fast Company points out. Fossil fuels account for about 18 percent of the world’s industrial CO2 emissions.

Fast Company outlines some of Syzygy’s accomplishments in 2023:

  • Gained an undisclosed amount of funding from Mitsubishi Heavy Industries.
  • Completed its Pearland manufacturing facility.
  • Wrapped up 1,000 cumulative hours of testing on its ammonia-splitting reactor cell, capable of producing 200 kilograms of hydrogen per day.

Houston subsea firm Zupt acquired in offshore tech deal

m&a activity

Houston-based Zupt LLC, a provider of advanced metrology, inspection, and engineering services for offshore energy and renewable projects, has been acquired by Columbus, Ohio-based Rosenxt Holding USA for an undisclosed amount.

Rosenxt says the deal, which closed July 21, represents another step in its long-term strategy to build a portfolio of technology and engineering capabilities for the subsea market in the energy sector.

“Our ambition has always been to think decades ahead,” Hermann Rosen, chairman of Switzerland-based Rosenxt Group, the parent company of Rosenxt Holding USA, said in a news release.

“The future of subsea and offshore industries will be shaped by intelligent technologies that fundamentally change how critical infrastructure is explored, installed, inspected and operated,” he added. “Zupt is another important building block in this vision.”

Rosenxt says offshore operators and installation contractors face pressure to execute subsea projects more efficiently amid workforce shortages, weather concerns, tougher safety standards, and rising capital and operating expenses.

“The offshore sector continues to embrace technologies that enhance data quality, reduce operational risk, and improve decision-making across the asset lifecycle,” Houston M&A attorney Amelia Zhang, who led law firm Norton Rose Fulbright’s representation of Zupt, added in the release.

Rosenxt provides services for the subsea market that combine sensing, robotics, AI, analytics and engineering. Zupt complements those services with offerings for operations, such as high-resolution 3D inspection, digital twin generation, and inspection and engineering technologies for subs.

Zupt President Keith Vickery founded the company in 2005.

Vickery says Zupt “has focused on solving some of the subsea industry’s most demanding marine construction and inspection challenges through innovative engineering, operational experience, and close collaboration with our customers.”

Mordor Intelligence estimates the value of the subsea market will climb from $19.75 billion this year to $25.03 billion in 2031. North America represents the largest segment of the global market.

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."
