Houston organization announces major partnership with DOE lab to spur energy innovation commercialization

R&D teammate

A new partnership between the Greater Houston Partnership and Argonne National Laboratory has been established to spur development of commercial-scale energy transition solutions.

The GHP and the Houston Energy Transition Initiative, or HETI, announced that it has signed a memorandum of understanding with Argonne National Laboratory, a federally-funded research and development facility in Illinois. The lab is owned by the United States Department of Energy and run by UChicago Argonne LLC of the University of Chicago.

“The U.S. Department of Energy’s national laboratories have long been the backbone of research, development, and demonstration for the energy sector," Bobby Tudor, CEO of Artemis Energy Partners and Chair of HETI, says in a news release. "The Partnership and HETI, working with our industry members, business community and top research and academic institutions, in collaboration with Argonne, will work across our energy innovation ecosystem to drive this critical effort for our region.”

The partnership, announced at HETI House at CERAWeek by S&P Global, is intended to provide resources and collaboration opportunities between Houston's energy innovation ecosystem — from corporates to startups — to "accelerate the translation, evaluation and pre-commercialization of breakthrough carbon reduction technologies," per the news release.

“A decarbonization center of excellence in Houston is the missing link in the region’s coordinated approach to advancing critical energy transition technologies needed to mitigate the risks associated with climate change, while also promoting economic growth and job creation for the region,” Tudor continues.

Established in 1946, Argonne works with universities, industry, and other national laboratories on large, collaborative projects that are expected to make a big impact on the energy transition.

“Partnerships are essential to realizing net zero goals,” Argonne Director Paul Kearns adds. “We are pleased to extend DOE national laboratory expertise and work with HETI to focus the region’s considerable energy and industrial assets, infrastructure, and talent on broad commercial deployment of needed technologies.”

Houston's history in oil and gas — as well as its momentum in the energy transition space — helped the city claim the top spot in this new report ranking. Photo via Getty Images

New report ranks Houston as the top city for foreign investment

by the numbers

For the second time, a report has analyzed the top markets in the United States for the rest of the world to do business in. This year, that top spot belongs to Houston.

The second annual FT-Nikkei Investing in America ranking, which came out this week from the Financial Times and international financial newspaper Nikkei, put the Bayou City — and six other Texas cities — at the top portion of the ranking. Houston's at No. 1, up four spots from last year, but Austin and four cities in the Dallas area also claim spots in the top 20.

The report looked at four dozen metrics, including workforce and talent, quality of life, openness, business environment, investment trends, and more.

In addition to the ranking, the Financial Times dove a little deeper into what made Houston a standout this year, interviewing many of Houston's most prominent business community members. The article points to the city's storied past as an oil and gas leader, also calling out its busy airports and global shipping ports, as well as its medical technology and aerospace industries. But one of the biggest factors in Houston's business climates success is its opportunity within the energy transition.

“We’re clear in Houston that if we’re going to continue to have prosperity — to the degree to define prosperity as job growth and wealth creation — it’s going to need to come from places other than the incumbent energy business,” Bobby Tudor, chief executive of Artemis Energy Partners, tells FT in the article.

Houston scored an overall 73 out of 100, and its scores across metrics in the report include:

  • Workforce and talent: 68/100
  • Openness: 80/100
  • Business environment: 64/100
  • Foreign business needs: 100/100
  • Quality of life: 47/100
  • Investment trends: 73/100
  • Aftercare: 69/100
Last year's top city was Miami, which ranks at No. 6 this year. Most of the top 10 cities in this year's report represent major gains on the ranking.This report falls in line with others in terms of noticing a change within the green economy in Houston. Earlier this year, personal finance website SmartAsset ranked the Houston metro area as the fifth best place in the U.S. for green jobs, which pay an average of 21 percent more than other jobs. The SmartAsset study found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.”

Houston investors back Austin software startup in $3.25M seed round

money moves

Houston-based investment firm Goose Capital led a $3.25 million round of seed funding revealed recently by Austin-based cleantech software company P6 Technologies.

Other participants in the round are Houston-based investment firms Artemis Energy Partners, Tupper Lake Partners, and Veritec Ventures. The seed round represents the first outside funding for P6, which maintains an office in Houston.

In conjunction with the seed funding:

  • Artemis founder and CEO Bobby Tudor has joined P6’s board of directors. He is an investor in Goose Capital.
  • Paal Kibsgaard, managing partner of Veritec, also has joined the P6 board. Kibsgaard is former chairman and CEO of Houston-based oilfield services company Schlumberger, which now does business as SLB.

Joe Berti, CEO of P6, says Kibsgaard’s “unparalleled experience” will benefit his company.

“Veritec’s strategic vision and active support of energy transition solutions align perfectly with our goals, and I am confident their contribution will be instrumental in shaping our future success,” Berti says in a news release.

Berti is former chief product officer of IBM’s sustainability software unit.

P6, founded in 2022, sells enterprise software to businesses in the energy, transportation fuel, and petrochemical sectors. The startup’s software for product lifecycle assessment enables measurement of the product-level intensity of greenhouse gas (GHG) emissions as energy companies try to achieve sustainability goals.

Tudor applauds P6 for helping fossil fuel-anchored companies reduce GHG emissions.

“Energy is the sector that needs a solution like P6 the most,” says Tudor. “P6 has the right approach and is going to make a step-change improvement to how product-level carbon intensity and GHG emissions are tracked today.”

Houston has responsibility and opportunity to lead the energy transition, say local leaders

the future is here

Houston has an integral role to play in the energy transition, and that role was thoroughly discussed at a recent conference taking place in the Bayou City.

This week, Houston hosted the 10X Summit: The Future Is Here, an event by Ten Across — an organization that focuses on social, economic, and climate change issues across the region around Interstate 10 from Los Angeles to Jacksonville. The three-day conference featured guest speakers who spoke to resiliency, water, the future of energy, and more.

Among these speakers included a handful of Houston researchers, political figures, and innovators — and much of their conversations overlapped related topics and themes, from Hurricane Harvey's legacy and impact on the business community to the role the city will play in the energy transition.

When it comes to the energy transition, here are the key messages Houston leaders shared with 10X attendees.

The energy transition can't happen without Houston

The topic of the energy transition came up right out of the gate for the summit. At the welcome reception on Tuesday, Bobby Tudor, CEO of Artemis Energy Partners and founder and former CEO of Tudor, Pickering, Holt & Co., spoke to the evolution of the industry and how Houston is a major factor in the energy transition's success.

“I don’t think (the energy transition) is going to happen without (Houston)," Tudor says at the fireside chat with Wellington Reiter, executive director of Ten Across. "There's a notion that the transition is inevitable. It’s inevitable — only if our technology continues to advance and improve, only if new assets get deployed, only if capital supports it, and only if the people who know and understand the energy systems are leaning in to make it happen.”

For Tudor, who served as chair of the Greater Houston Partnership in 2020 and made it his mission to communicate the importance of industry evolution during his tenure, Houston businesses motivated by opportunities in business should be looking at the energy transition.

“We’re very good in Houston that, when we see a dollar bill lying on the ground, we bend over and pick it up. Right now, there’s fantastic opportunity in the energy transition space," he says. "We have both a responsibility and an opportunity to be the leaders in the global energy transition.”

Mayor Sylvester Turner in his chat with Reiter on Thursday addressed how some might think that Houston — a headquarters for some of the biggest oil and gas giants — might not be the right city to lead a cleaner energy system, but Turner argued that's exactly why it has to happen here.

“We are the energy capital of the world," he says. "The reality is we have some of the largest greenhouse gas emitters principally located right here in Houston. To the extent of leading an energy transition, the impact is not just locally. The impact is globally.”

Barbara Burger, former president of Chevron Technology Ventures and an energy tech startup adviser, explained how integral the relationship between the energy industry and Houston is.

“As the energy system evolves, so does Houston," she says. “I think it’s our opportunity to lose."

The role of corporate incumbents 

Burger's discussion, which took place on Wednesday, spoke to the role of incumbents — corporations that have been operating in the energy industry for decades — in the transition. She explained how the process can't move forward without these parties.

“The incumbents need to be a part of the energy transition. There are parts of our society that don’t want them to be, and I find that unfortunate," she says. "For one, we’re not going to decarbonize the energy system unless they are a part of it. Two, there are a lot of skills and capabilities and assets in the incumbents to do that.

"What I don’t think the incumbents will do is they won’t lead it," she continues. "Many will be leaders in the new energy system, but they won’t be the ones first up the hill.”

Burger compares the energy and the automotive industries. Tesla acted as a disruptor to major auto companies, and then they followed suit. The disruptors and catalysts the energy industry will be a combination of startups, investors, governments, universities, and employee bases.

“We’re not going to throw away the current energy system," she says. "We’re going to evolve it and repurpose it.”

Houston has the ingredients

Tudor addressed the existing infrastructure — from physical pipes to expertise and workforce — that Houston has, which makes for an ideal location for innovation and progress in the transition.

“For a lot of reasons, it’s very clear that unless Houston leans in, we’re not going to find the solutions we need to transition our energy systems to much lower CO2 emissions," he says.

The GHP established the Houston Energy Transition Initiative in 2021 to concentrate Houston efforts within the future of energy. Tudor says this initiative is focused on what can be done now in town — attracting clean energy startups, developing a hydrogen hub, building facilities for green hydrogen production — to lead to a better future.

“We want to look up 20 years from now and find Houston is still — if not more than ever — the energy capital of the world," he says. "We believe that energy systems globally in 20 years will look quite different from how they look today. And that means Houston will look very different from how it looks today."

Burger emphasized some of the challenges — as well as opportunities — the city has considering its long history within the sector.

“Houston has benefitted from a vibrant, strong U.S. energy industry,” she says. “Keeping strong companies and keeping Houston attractive for the energy business is critical.”

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
