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.

Energy AI company opens first U.S. office in Houston after Halliburton deal

houston expansion

Building on its partnership with Houston-based oilfield services provider Halliburton, energy-sector AI company Shape Digital recently opened an office at The Ion. It’s the company’s first U.S. location.

Shape Digital’s workforce in Houston includes employees specializing in tech support, business development and client services. The company’s local hiring projections and headcount weren’t available. The new office will be located within Industrious at the Ion, according to Rice Alliance.

A key driver of the new Houston office: The company forecasts North America will account for more than 20 percent of its business in 2027.

“North America is a critical market for industrial innovation, and Houston sits at the center of companies driving that progress,” Caio Sene, vice president of client services at Shape Digital, said in a release. “Growing our presence here allows us to work alongside operators as they look for practical ways to turn existing operational data into clear recommendations for what to do next.”

Shape Digital, which also has offices in Singapore and Brazil, develops decision-making platforms for the oil and gas sector.

The Ion District office gives Shape Digital a presence close to Halliburton’s headquarters. In May, the two companies forged a partnership to combine Halliburton’s Digital Field Solverdecision-making system with Shape Digital’s AI portfolio.

Shape Digital layers AI software atop existing operations data rather than replacing legacy systems or adding new software.

The company’s suite of AI agents draws on more than 200 operations-monitoring algorithms, continually learning from company and industry data. The suite comprises four products: Shape Aura, Shape Lighthouse, Shape Lumen and Shape Reef.

Shape Digital says that by working with a customer’s existing operations data, it can deliver ROI in less than two months without any additional investment in equipment or infrastructure.

The company is a 2021 spinoff of Japan-based Modec. Modec builds, owns, and operates floating offshore oil and gas production facilities. Its Modec America subsidiary is based in Houston.

Houston energy startup names former Cheniere execs to C-suite

new leaders

Houston-based energy infrastructure startup Joulent has brought aboard a new chief financial officer and new chief operating officer—both former executives at Houston-based Cheniere Energy.

The C-suite moves come three months after Joulent raised $1.75 billion from National Grid Ventures.

Michael Wortley joins Joulent as co-president and CFO. Wortley most recently was executive vice president and CFO at Cheniere, an LNG producer and exporter.

In conjunction with Wortley’s hiring, Brian Boland, who was Joulent’s interim CFO, has been named executive vice president, chief investment officer, and head of strategy.

Corey Grindal comes to Joulent as co-president and COO. Grindal most recently was executive vice president and COO at Cheniere.

“As Joulent evolves to meet the growing demand for power infrastructure, our expanded leadership team will help ensure we continue delivering the execution certainty our customers, partners, and investors expect,” Chris James, Joulent’s founder and CEO, said in a press release.

“Corey and Michael are accomplished operators with exceptional records of building and leading world-class energy infrastructure businesses, where they have embedded a culture defined by operational excellence and disciplined execution,” James added.

Joulet builds dedicated power-generating facilities that feed directly into data centers and other power-dependent facilities. This eliminates the need for companies to draw power from grids.

“With an initial multi-gigawatt development portfolio and strategic partnerships across the energy, infrastructure, and data center ecosystem, Joulent is helping remove power constraints to enable the next chapter of American innovation and U.S. reindustrialization,” the company says.

The $1.75 billion minority investment from National Grid Ventures complements Joulent’s existing partnerships.

Joulent, founded in 2023, emerged from stealth mode this summer. The company was founded by investment firm Engine No. 1.

Joulent’s first project, the Project Kilby natural gas facility in West Texas, will be co-located with a Microsoft data center. It’ll deliver about 2.67 gigawatts of power under a 20-year deal between Microsoft and Energy Forge One, a 50/50 joint venture between Chevron and Joulent.
