Climatech company Dimensional Energy, which operates a Houston office, has scooped up $20 million in series A funding.

Founded in 2014, Ithaca, New York-based Dimensional Energy specializes in producing decarbonization technology, sustainable aviation fuel, and carbon emissions-derived fuels and materials. South Korea’s Envisioning Partners led the round, with participation from investors such as:

  • United Airlines’ Sustainable Flight Fund
  • Microsoft’s Climate Innovation Fund
  • RockCreek Group’s Smart Aviation Futures fund
  • DSC Investment
  • Delek US
  • Empire State Development
  • Climate Tech Circle

The company also says it’s working toward becoming a certified B Corporation. Businesses that achieve this certification seek to balance purpose and profit.

Dimensional Energy says the $20 million funding round positions it for “significant growth,” enabling it to:

  • Build the world’s first advanced power-to-liquid fuel plant and continue developing commercial power-to-liquid fuel plants.
  • Roll out the company’s initial B2B and B2C products, such as a fossil-free surf wax and a cruelty-free fat alternative for vegan food manufacturers.
  • Evolve the company’s proprietary reactor and catalyst technologies, which are being tested at its pilot plant in Tucson, Arizona.

“The world needs immediate and rapid decarbonization across all sectors, and Dimensional Energy shows great promise as a cleaner and lower-carbon aviation solution alongside reductions in industrial emissions,” Brandon Middaugh, senior director of Microsoft’s Climate Innovation Fund, says in a news release.

Dimensional Energy’s technology transforms carbon dioxide emissions into sustainable aviation fuel (SAF), renewable diesel, and synthetic paraffin that can be refined into more than 6,000 everyday products.

“Dimensional Energy particularly stood out to us for their differentiated technology, exceptional team, and significant progress to date towards producing SAF and other industrial products from CO2,” says Justin Heyman, managing director at RockCreek. “This technology can significantly reduce the environmental footprint of the airline industry.”

United opens $32M expansion of high-tech training center, plans to hire hundreds

first-class facility

A new study highlights United Airlines’ multibillion-dollar impact on the Houston economy as the company eyes the addition of 1,800 local employees this year.

The study, done by Chicago-based consulting firm Compass Lexecon, shows United’s hub at George Bush Intercontinental Airport along with spending by foreign visitors arriving on flights operated by United and its partners contribute an estimated $5.3 billion in annual gross domestic product (GDP) in Texas.

Furthermore, the study says United’s direct employment in Houston accounts for $1.2 billion in annual economic activity, and the local hub indirectly supports 56,000 local jobs. Houston is one of United’s seven U.S. hubs.

“United continues to be a great partner and business leader in the city of Houston, connecting Houstonians to the world and investing in vital infrastructure projects that help enhance the travel experience for millions of travelers,” Houston Mayor Sylvester Turner says in a news release.

The economic impact study was released in conjunction with the opening of the $32 million expansion of United’s flight attendant training center in Houston. Highlights of the 56,000-square-foot facility include a roughly 400-seat auditorium, and a 125,000-gallon pool and mock fuselage for practicing evacuation of a plane during a water landing.

This year, the Chicago-based airline is on track to add 15,000 workers, including 4,000 flight attendants. United employs more than 11,000 people in Houston and plans to hire 1,800 more in 2023.

The airline plans to train more than 600 flight attendants per month at the enlarged Houston facility.

“The best flight attendants in the industry deserve the best, most modern training facility in the country,” United CEO Scott Kirby says in a news release. “This expansion project is yet another example of an investment we made during the depths of the pandemic that will support our employees, further improve our ability to deliver great service, and set United up for success in 2023 and beyond.”

New United flight attendants will go through a six-and-a-half-week training course at the Houston facility and then return every 18 months to stay up to date on flight qualifications.

United posted profit of $737 million last year, down 75.5 percent from the pre-pandemic year of 2019, on operating revenue of nearly $44.5 billion, up 3.9 percent from 2019.

In 2022, the airline’s investment arm, United Ventures, announced an investment of up to $37.5 million in Houston-based NEXT Renewable Fuels. The company, which produces renewable fuel for the aviation sector, is developing a biofuel refinery in Oregon.

NEXT plans to go public this year through a SPAC merger with a publicly traded shell company.

big moves

It’s been a momentous month for Houston-based NEXT Renewable Fuels Inc.

On November 15, United Airlines Ventures announced an investment of up to $37.5 million in the next-generation, low-carbon fuel producing company.

Just a week later, the company revealed it’s going public through a SPAC merger with Industrial Tech Acquisitions II Inc. The deal, expected to close in the second quarter of 2023, assigns a $666 million equity value to NEXT. The publicly traded company will be named NXTCLEAN Fuels Inc.

NEXT, founded in 2016, produces low-carbon fuels from organic feedstock. The company plans to open a biofuel refinery in Port Westward, Oregon, that’s set to start production in 2026. The refinery could produce up to 50,000 barrels per day of sustainable aviation fuel, renewable diesel, and other renewable fuels.

“West Coast states are demanding a clean fuels conversion of the transportation and aviation industries with aggressive targets necessitating rapid increases in clean fuel supplies,” Christopher Efird, executive chairman and CEO of NEXT, says in a news release. “[The company] is advancing toward becoming one of the largest U.S.-based suppliers of clean fuels for these markets, and is investigating and pursuing potential vertical expansion into other clean fuels.”

The proposed public listing of NEXT’s stock on the Nasdaq market and United’s investment are poised to help NEXT reach its goal of becoming a leader in the clean fuel sector. United’s investment appears to be the first equity funding for NEXT.

“Right now, one of the biggest barriers to increasing supply and lowering costs of sustainable fuel is that we don’t have the infrastructure in place to transport it efficiently, but NEXT’s strategic location and assets solve that problem and provide a blueprint for future facilities that need to be built,” Michael Leskinen, president of United Airline Ventures, says in a news release.

United’s investment arm, launched in 2021, targets ventures that will complement the airline’s goal of achieving net-zero emissions by 2050.

United Airlines launches new service to help travelers skip the lines at Bush Intercontinental

simpler skies

Houston travelers on United Airlines now have access to a new, virtual, on-demand customer service aimed at simple, contact-free, real-time information and support. The new feature is available at George Bush International Airport, as well as Chicago O'Hare, and will roll out to other hubs by the end of the year, according to a press release.

Dubbed Agent on Demand, the new United service is available on any mobile device to call, text, or video chat live with an agent. Customers can scan a QR code displayed on signage throughout United's hub airports, or access the platform through self-service kiosks. From there, customers will be connected to an agent by phone, chat or video, based on their preference, according to the airline.

Travelers can get answers on seat assignments, boarding times, upgrades, standby list, flight status, rebooking, and more. Agent on Demand is aimed at convenience; customers cab go virtual as opposed to standing in line for answers.

For international travelers, more than 100 languages will be available via chat. (Customers type in their preferred language and the messages will be automatically transcribed in English for the agents — and in the selected language for the customer.)

United is the first airline to debut this technology, which is aimed at safety during the pandemic and convenience, United notes in a press release.

"We know how important it is for our customers to have more options for a contactless travel experience and this tool makes it easy to quickly receive personalized support directly from a live agent at the airport while maintaining social distancing," said Linda Jojo, United's executive vice president for technology and chief digital officer, in a statement. "Agent on Demand allows customers to bypass waiting in line at the gate and seamlessly connect with customer service agents from their mobile device, ensuring they continue to receive the highest levels of service while also prioritizing their health and safety."

In late November, United announced the expansion of its customer COVID-19 testing efforts to include flights departing Houston to select destinations in Latin America and the Caribbean.

Houston-based FlightAware, a software company that tracks flights, is growing. Cameron Casey/Pexels

Houston flight-tracking software company grows its local and international presence

taking flight

FlightAware LLC's business success has, for the most part, flown under the radar in Houston.

Many travelers know about the B2C flight-tracking functionality of FlightAware. "That's a very, very competitive space. We play in that space, but it's not our core business," founder and CEO Daniel Baker says.

These days, the privately held Houston company earns most its revenue from the B2B data it provides to airlines and other aviation clients, according to Baker. He declines to reveal revenue figures, but notes that the company — which bills itself as the world's largest flight-tracking and flight data platform — hasn't taken a penny of outside funding since it started in 2005.

Today, FlightAware employs about 110 people, with the majority of them located in Houston, Baker says. The company also maintains offices in Austin, New York City, London, and Singapore.

By the end of 2020, the companywide workforce should exceed 135, as FlightAware aims to add three new hires per month this year in areas such as Internet of Things, data science, sales, and administration, Baker says. Most of the new employees will work in Houston.

Baker says FlightAware takes an aggressive approach to hiring, with the goal of bringing aboard "really awesome people" who share levels of talent, collaboration, and "culture fit" similar to those of current employees.

By the end of 2021, FlightAware likely will run out of room in its 24,000-square-foot office at 11 Greenway Plaza in the Greenway/Upper Kirby area, Baker says. That means FlightAware will need to take about 15,000 additional square feet at 11 Greenway Plaza or relocate to a different building, he says. The company moved into its current home in 2017 from a 14,000-square-foot office at 8 Greenway Plaza.

Baker, who's a private pilot and a board member of the Smithsonian Institution's National Air and Space Museum, launched the company 15 years ago as a way to combine two passions: software development and aviation.

"It was originally a hobby, and it became a business," Baker says. "It's an unlikely story. We're really, really fortunate that the timing was right."

Although FlightAware started off tracking flights in the general aviation space, it has since expanded to supply aviation data to both travelers and businesses. Each month, about 15 million passengers use the FlightAware app, which earns praise from a slew of travel critics.

Among flight-tracking apps, FlightAware "is a bit of a Swiss army knife," Condé Nast Traveler magazine observes. The FlightAware app lets you follow flights in real time, including where an incoming plane is coming from, how close it is to arriving, and what kind of weather it's encountering en route, the magazine notes. In addition, the app can send push notifications about arrivals, departures, gate changes, flight delays, and flight cancellations.

Now, FlightAware relies on the consumer-facing technology "as a stepping stone to have a bigger impact," Baker says. "Every project that we undertake is larger than the last one."

That "bigger impact" involves cranking out data that enables commercial airlines, cargo carriers, business aviation companies, and air traffic controllers to be proactive instead of reactive regarding flight activity, he says.

FlightAware's corporate customers include United Airlines, Hawaiian Airlines, business-jet operator NetJets and GPS technology provider Garmin. Baker says a North American airline that he declines to name will soon roll out FlightAware technology to its airport gate agents.

For airlines, FlightAware's software delivers data to cut down, among other issues, on problems with flight delays, gate assignments, and flight connections, Baker says. FlightAware pulls data from its network of more than 25,000 receivers on all seven continents.

While the consumer-oriented features of FlightAware's technology face competition from the likes of FlightStats, FlightView, and The Flight Tracker, the B2B landscape is less populated. Over the years, corporate giants like Airbus, Boeing, and IBM have tackled aviation data on their own but have wound up forging data partnerships with FlightAware, according to Baker.

"We see every potential competitor as a future customer," Baker says.

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.
