A carbon innovation initiative in collaboration with Greentown Houston has named its new cohort.

The Carbon to Value Initiative (C2V Initiative) — a collaboration between NYU Tandon School of Engineering's Urban Future Lab (UFL), Greentown Labs, and Fraunhofer USA — has named nine startup participants for the fourth year of its carbontech accelerator program.

"Once again, the C2V Initiative has been able to select some of the most promising carbontech startups through a very competitive process with a 7 percent acceptance rate," Frederic Clerc, director of the C2V Initiative and interim managing director of UFL, says in a news release. "The diversity of this cohort, in its technologies, products, geographies, and stages, makes it an amazing snapshot of the rapidly evolving carbontech innovation landscape."

The cohort was selected from over a hundred applications from nearly 30 countries. In the six-month program, the nine companies gain access to the C2V Initiative's Carbontech Leadership Council, an invitation-only group of corporate, nonprofit, and government leaders who provide commercialization opportunities and identify avenues for technology validation, testing, and demonstration.

The year four cohort, according to the release, includes:

  • Ardent, from New Castle, Delaware, is a process technology company that is developing membrane-based solutions for point-source carbon capture and other chemical separations.
  • CarbonBlue, from Haifa, Israel, develops a chemical process that mineralizes and extracts CO2 from water, which then reabsorbs more atmospheric CO2.
  • MacroCycle, from Somerville, Massachusetts, develops a chemical recycling process to turn polyethylene terephthalate (PET) and polyester-fiber waste into "virgin-grade" plastics.
  • Maple Materials, from Richmond, California, develops an electrolysis process to convert CO2 into graphite and oxygen.
  • Oxylus Energy, from New Haven, Connecticut, develops a direct electrochemical process to convert CO2 into fuels and chemical feedstocks, such as methanol.
  • Phlair, from Munich, Germany, develops a renewable-energy-powered Direct Air Capture (DAC) system using an electrochemical process for acid and base generation.
  • Secant Fuel, from Montreal, Quebec, Canada, develops a one-step electrocatalytic process that converts flue gas into syngas.
  • RenewCO2, from Somerset, New Jersey, is developing an electrochemical process to convert CO2 into fuels and chemicals, such as sustainable aviation fuel (SAF) or propylene glycol.
  • Seabound, from London, England, builds carbon-capture equipment for new and existing ships.

"The depth and breadth of carbontech innovations represented in this applicant pool speaks volumes to this growing and dynamic industry around the world," adds Kevin Dutt, Interim CEO of Greentown Labs. "We're eager to support these nine impressive companies as they progress through this program and look forward to seeing how they engage with the CLC now and into the future."

The C2V Initiative kicked off at a public event on Sept. 19 at Greentown Houston and via livestream.

10 most-promising energy tech startups named at annual Houston event

top companies

Investors from around the world again identified the most-promising energy tech startups at the Rice Alliance for Technology and Entrepreneurship's annual event.

"The recognition that Houston is the epicenter of energy transition is growing. It's something we are championing as much as possible so that the world can know exactly what we're doing," Paul Cherukuri, chief innovation officer at Rice University says at the 21st annual Energy Tech Venture Forum.

The event took place during the inaugural Houston Energy and Climate Startup Week, and nearly 100 startups from 23 states and seven countries pitched investors Wednesday, September 11, and Thursday, September 12. At the conclusion of the event, the investors decided on 10 companies deemed "most promising" from the presentations.

This year's selected companies are:

  • Revterra, a Houston-based company innovating within kinetic battery technology to enable faster and cleaner electric vehicle charging.
  • From Austin, 360 Mining is a modular data center provider for the oil and gas producers.
  • New York company Andium is a centralized and optimized operations platform for large energy companies.
  • Elementium Materials, a local Katy-based company, created its battery technology that originated out of MIT.
  • Splight is a San Mateo, California-based technology platform that provides real-time operational data based on inverter-based resources assets.
  • Los Angeles-based Mitico, one of the Rice Alliance Clean Energy Accelerator's class 4 participants, provides services and equipment for carbon capture through its granulated metal carbonate sorption technology.
  • From Cambridge, Massachusetts, Osmoses is changing the way molecular gas separations are performed within the chemical, petrochemical, and energy industries.
  • Rice Alliance Clean Energy Accelerator class 4 participant CORROLYTICS, based in Houston, has a corrosion detection and monitoring technology. The company also won over the crowd and secured the People's Choice win too.
  • Ardent, based in New Castle, Delaware, has developed a membrane technology for point-source carbon capture.
  • New Haven, Connecticut-based Oxylus Energy produces an alternative fuel from converting CO2 into green methanol.

Last year, investors named its selection of most-promising companies at Rice.

"We have a responsibility as a city to lead energy transition," Cherukuri continues. "A lot of the investments we're making at Rice are going to change the world."

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."

Rice University launches new venture fund for university-affiliated startups

startup support

Rice University has launched its new One Giant Leap Ventures Fund I, which will invest in the university’s spinouts and alumni-founded startups.

The early-stage institutional venture fund will function with a hybrid structure that allows for participation from traditional equity investors and philanthropic investors. According to the university, the fund will invest up to $500,000 per Rice-affiliated company.

To be considered eligible for funds, companies must use intellectual property licensed by the university or be led or founded by alumni.

One Giant Leap will draw on support and mentorship from Rice’s pool of 60,000 alumni and aims to create educational opportunities within the investment phases, work with graduate and undergraduate venture students, explore the scaling and commercialization of their ideas, and help investigate all the facets of venture capital.

“Rice alumni bring an extraordinary depth of experience as entrepreneurs, investors and industry leaders, and One Giant Leap creates new ways to put that expertise to work for the next generation of Rice innovators,” Stephen Bayer, vice president for development and alumni relations, said in a news release. “It strengthens the connection between our alumni and the university while giving them meaningful opportunities to mentor, advise and support Rice-affiliated companies as they grow.”

The fund held its first close in August and made its first investment into Rice brain health spinout Motif Neurotech. Led by Rice faculty member Jacob Robinson, Motif is working to commercialize a minimally invasive neurostimulator that targets treatment-resistant depression. In May, the FDA approved the company to move forward with its first clinical trial.

“Research produces breakthrough technologies and our academic environment forms outstanding entrepreneurs,” said Adrian Trömel, the fund’s managing director, a Rice alumnus and a startup founder who also serves as Rice’s interim chief innovation officer.

One Giant Leap joins the already long list of Rice-led programs that foster innovation, including the Liu Idea Labs for Innovation and Entrepreneurship’s Innovation Fellows and Summer Venture Studio, the Rice Alliance’s Business Plan Competition, the Ion District, Woodside Rice Decarbonization Accelerator, Rice Nexus, the Biotech Launchpad and RBL Ventures and its upcoming 200,000 square-foot research lab the Arc.

“With One Giant Leap, I am excited that we are creating a unique structure that brings together traditional investment and philanthropic participation to invest in and help catalyze our startups, engage the deep expertise within the Rice ecosystem and transform those strengths into real-world impact,” Trömel added in the release.
