Greentown Labs has named the six participating climatetech startups for an accelerator for a global energy leader.

Shell and Greentown Labs announced the cohort for Greentown Go Make 2023 — a program designed to accelerate partnerships between startups and corporates to advance carbon utilization, storage, and traceability solutions with manufacturing in mind. Shell, which invests in net-zero and carbon-removal technologies, is hoping to strategically align with startups within carbon utilization, storage, and traceability across the energy transition spectrum.

“At Greentown Labs we recognize and appreciate the role energy incumbents must play in the energy transition, and we’re eager to facilitate meaningful partnerships between these impressive startups and Shell—not only to advance these technologies but also to help Shell achieve its sustainability goals,” Kevin Knobloch, CEO and President of Greentown Labs, says in a news release. “We know carbon utilization, storage, and traceability will play a critical role in our collective efforts to reach net-zero, and we’re enthusiastic about the potential impact these companies can have in that work.”

The cohort, selected from 110 applications, is co-located at Greentown's Houston and Somerville, Massachusetts, locations and includes:

  • Portland-based Caravel Bio is developing a novel synthetic biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments.
  • Circularise, which is based in the Netherlands, is developing a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains.
  • Corumat, based in Washington, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
  • Cambridge, Massachusetts-headquartered Lydian develops a fully electrified reactor that can convert a variety of gaseous, non-fossil feedstocks into pure syngas with high efficiency.
  • Maple Materials from Richmond, California is developing a low-cost electrolysis process to split carbon dioxide into graphite and oxygen.
  • Ontario, Canada-founded Universal Matter develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.

The program, which includes $15,000 in non-dilutive stipend funding for each company, will work closely with Shell and Greentown over six months via mentorship, networking opportunities, educational workshops, and partnership-focused programming to support collaboration. Go Make 2023 concludes with a showcase event on March 27 at Greentown Labs’ Houston location.

This week, Shell announced another accelerator cohort it's participating in. The Shell GameChanger Accelerator, a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), named four West Coast climatetech companies: DTE Materials, Hexas Biomass, Invizyne Technologies, and ZILA BioWorks. The program provides early-stage cleantech startups with access to experts and facilities to reduce technology development risk and accelerate commercialization of new cleaner technologies.

“Tackling the climate challenge requires multifaceted solutions. At Shell, we believe technology that removes carbon dioxide from the atmosphere will be essential for lowering emissions from energy and chemical products,” Yesim Jonsson, Shell’s GCxN program manager, says in a statement. “The companies in GCxN's sixth cohort embody these objectives and have the potential to usher in a more sustainable future.”

Houston is one of the most diverse cities in the nation, and that trend carries over into its innovation and startup ecosystem.

As part of the 2025 Houston Innovation Awards, our Minority-founded Businesses category will honor an innovative Houston startup founded or co-founded by BIPOC or LGBTQ+ representation.

Five minority-founded businesses have been named finalists for the 2025 award. The finalists, selected by our esteemed panel of judges, range from a wearable health tech device company to a clean chemical manufacturing business to a startup with a lunar mission.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. Then join us at the Houston Innovation Awards on Nov. 13 at Greentown Labs, when the winner will be unveiled at our live awards ceremony.

Tickets are on now for this exclusive event celebrating all things Houston Innovation.

Capwell Services

Houston-based 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 US and Canada, equivalent to more than 400 million metric tons of CO2e per year. 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 current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has not raised VC funding, but has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTechNexus LiftOff and others. Lee is an Activate 2025 fellow.

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. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch and other organizations.

Torres Orbital Mining (TOM)

Space tech company Torres Orbital Mining aims to pioneer the sustainable extraction and processing of lunar regolith and designs and builds robotic systems for excavating, classifying, and delivering lunar material. The company aims to accelerate a permanent and ethical human presence on the Moon.

The company was founded this year by Luis Torres, a current MBA candidate at Rice Business.

Wellysis USA Inc.

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.

The Ion taps John Reale for startup and investor role

new hire

The Ion has named John "JR" Reale as its director for startups and investor engagement.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."

Houston's IAH soars in new ranking of U.S. airports with best dining

Flying High

Here's news that'll make a flight delay at Houston's George Bush Intercontinental Airport a bit more palatable: IAH arrives at No. 12 in a new ranking of the country’s best airports for food and beverage options.

The 2025 study by commercial furniture manufacturer Restaurant Furniture relied on Google reviews of food and beverage establishments at the busiest U.S. airports to come up with its list. The study included only those restaurants and bars with at least 20 Google reviews.

IAH earned an average Google review rating of 3.29 out of 5 stars for its food-and-beverage establishments.

The study analyzed 61 restaurants and bars at George Bush Intercontinental Airport. The Houston airport’s highest rated establishment was Pappadeaux Seafood Kitchen. That Pappadeux location garnered an average Google review rating of 4.48 out of 5. George Bush International also is home to the study’s highest-rated Chick-fil-A and Whataburger restaurants.

Several years ago, IAH made a major effort to upgrade its dining options by partnering with local chefs such as Chris Shepherd, Ryan Pera (Coltivare), and Greg Gatlin (Gatlin's BBQ) on concepts for Terminal C North. More recently, a change in the city's airport concessions contract brought local favorites such as The Annie Cafe and Common Bond to the George Bush.

“Airports aren’t usually renowned for their choices of bars and restaurants, and this is often because people just want to get through the airport and onto their final destinations as quickly as possible,” Nick Warren, head of e-commerce at Restaurant Furniture, says in a release. “However, a good airport bar or restaurant can provide a great rest stop after a long flight, and these positive experiences can go a long way towards travelers choosing which airport they will fly from in the future.”

Dallas Fort Worth International Airport soared to No. 1 in the rankings. Restaurants and bars at DFW earned an average of 3.56 out of 5 stars on Google — the highest number among 31 airports.

Just like in Houston, among 74 locations at DFW, the study found Pappadeaux Seafood Kitchen in Terminal A scored the highest average Google review rating — 4.59. DFW also boasts the top-rated IHOP, McDonald’s, Panera Bread, and Panda Express among the 31 airports that were analyzed.

Rounding out the top five airports with best food are Miami International Airport (No. 2), San Francisco International Airport (No. 3), Denver International Airport (No. 4), and Hartsfield-Jackson Atlanta International Airport (No. 5).
