Houston to host cleantech collaboration with delegation from Belgium

this week

A delegation of nine startups from Antwerp, Belgium, along with industry experts will visit Houston from December 2 through December 6, which will include The Greater Houston Partnership, Greentown Labs, The Ion, and The Cannon.

The delegation will represent cleantech, sustainable chemistry, and energy tech sectors to engage with Houston’s energy transition ecosystem and identify collaboration and investment opportunities.

Houston-based energy tech-oriented companies will be invited to the pitching event for Antwerp and Houston Cleantech Entrepreneurs from 2 to 5 pm on December 3 at The Ion. Interested entrepreneurs can register at this link.

Antwerp and Houston are considered two of the world's largest petrochemical hubs, and also part of the leading innovators in the cleantech, sustainable chemistry, and energy tech sectors. The event will be organized by the Port of Antwerp-Bruges, BlueChem (an Antwerp-based sustainable chemistry incubator), the city of Antwerp, and Flanders Investment and Trade.

“Antwerp and Houston are known for their ports and petrochemical industries, but fewer people realize the remarkable cleantech, sustainable chemistry, and energytech ecosystems that have emerged around these hubs,” Nathalie Mathys, head of office at FIT Houston, says in a news release.

The Port of Antwerp-Bruges is known for innovating new technologies, which includes 5G, digital twins, artificial intelligence, drones, and advanced sensors. Antwerp has over 350 startups and nine incubators and accelerators.

“This delegation visit highlights the potential for collaboration between two of the most dynamic regions in these fields, paving the way for a cleaner, more sustainable future,” adds Mathys.

call for companies

Two Houston organizations are collaborating on a pitch competition and event that will focus on technologies that will transform operations.

The Cannon and Chevron Technology Ventures are partnering to present "Facilities of the Future," an event taking place at The Cannon West Houston on September 21.

"For over 100 years, Chevron has been a leader in leveraging technology to reduce risk and optimize efficiency in our facilities. Facilities that span all portions of the energy value chain including distributed unconventional wells, offshore deepwater platforms, and complex processing facilities, i.e. refineries, LNG plants," reads a statement about the competition. "But we also recognize the pace of change for technology is rapidly increasing and that our greatest potential lies in our ability to capitalize on these emerging technologies."

The companies, which must have at least $25,000 in annual revenue to qualify, will be selected by CTV and The Cannon and have until September 1 to apply online. The program is seeking participants with technology addressing one or more of Chevron's goals at its facilities:

  • Removing people from hazardous environments (e.g., confined spaces, working at heights)
  • Reducing the environmental impact (e.g., leak detection, emissions monitoring),
  • Increasing the operational efficiency (e.g., autonomous operations, advanced inspection capabilities, predictive asset health capabilities)

Each company will conduct a five-minute pitch followed by 10 minutes of Q&A. The winner, which will be announced at the conclusion of the event, have the opportunity to work on a field trial with Chevron and six months of free workspace at The Cannon.

Tickets for the event, which will provide drinks and networking, are free and registration is available online.

Rice University spinouts named among 50 top cleantech companies to watch

green team

Two Rice University spinouts, Coflux Purification and DexMat, appear on a new list of the world’s 50 cleantech companies to watch.

Cleantech Group’s 2026 Cleantech 50 to Watch list recognizes early-stage companies “creating groundbreaking solutions to address some of the world’s most pressing environmental and sustainability challenges.”

Cleantech Group, a market research, consulting, and events company, selects the 50 honorees based on insights from analysts and early-stage innovators, along with public nominations.

Destroying “forever chemicals”

Coflux, founded in 2024, offers an onsite treatment system that captures and destroys manufactured “forever chemicals”—per- and polyfluoroalkyl substances—in water and wastewater. It’s a member of Greentown Houston.

Alec Ajnsztajn, CEO; Jeremy Daum, chief technology officer; and Dana Vazquez, chief commercial officer, co-founded Coflux. Ajnsztajn and Daum earned doctoral degrees from Rice, and Vazquez earned an MBA from the university.

Coflux spun out of Rice labs directed by professors Rafael Verduzco and Pulickel Ajayan.

Last year, Coflux received a $175,000 grant from the U.S. Food and Drug Administration’s National Institute of Food and Agriculture. The startup has also raised more than $500,000 in non-dilutive funding, including $80,000 awarded in 2024 by Rice’s One Small Step Grant program.

Promoting an alternative to copper

DexMat, founded in 2015, produces carbon nanotube products such as fibers, yarns, cables, and fabric. The company’s products address demand for materials that can reduce carbon emissions, according to CB Insights.

Its main product, Galvorn, is a copper alternative made of carbon nanotube fibers. CB Insights says Galvorn is engineered to be lighter and stronger than traditional conductive materials like carbon and steel. It’s used in industries such as energy, aerospace, defense, automotive, consumer electronics, and health care.

DexMat emerged from Matteo Pasquali’s Carbon Lab at Rice. Pasquali, co-founder of DexMat, co-invented the company’s technology with the late Nobel Prize-winning chemist Rick Smalley. Smalley was a professor of chemistry, physics, and astronomy at Rice.

Pasquali is a professor of chemical and biomolecular engineering, chemistry, materials science, and nanoengineering at Rice. He co-founded DexMat with Rice graduate Dmitri Tsentalovich, the company’s director of product innovation.

Earlier this year, DexMat raised $5 million in seed funding from Non Sibi Ventures, Governance Partners, Tailwind Futures, BetterWay, Capital Factory, and other investors. The company also secured $3 million in non-dilutive funding.

In 2023, DexMat raised $3 million in a pre-seed round led by Shell Ventures.

TotalEnergies expands solar joint venture with $1.2B portfolio in Texas, Ohio

solar expansion

TotalEnergies, a French company whose U.S. headquarters is in Houston, announced this month that it is expanding its renewable energy joint venture with New York-based investment firm KKR by adding 700 megawatts of utility-scale solar projects.

The deal will add three utility-scale solar assets in Texas and Ohio, which are expected to reach commercial operation by Q1 2027, according to a news release from the company. The portfolio is valued at $1.2 billion.

The 50/50 joint venture between TotalEnergies and KKR currently holds 1.4 gigawatts of renewable energy and will grow to 2.1 gigawatts.

The new deal is expected to close this year. Once completed, TotalEnergies will operate the assets. The electricity generated from the solar projects will be sold to third parties, the company reports.

The companies originally formed the joint venture about a year ago when TotalEnergies sold KKR a 50 percent stake in a North American solar portfolio valued at $1.25 billion. The deal originally included six utility-scale solar assets, primarily located in the U.S.

“TotalEnergies is a renewable energy industry leader globally, and we are thrilled to establish this joint venture with the TotalEnergies team to support their renewables business," Cecilio Velasco, managing director KKR, said in a release last year. “We have long been investors in renewables through our infrastructure platform, having committed more than $23 billion to date in energy transition investments. TotalEnergies’ North American solar portfolio is a great fit for us, representing high-quality renewable energy assets with long term contracts.”

TotalEnergies reports that by June 2026 it held more than 37 gigawatts of gross renewable power generation capacity. It aims to achieve over 100 terawatt-hours of net electricity production by 2030.

The company signed a major power purchase agreement with Google earlier this year. Through the deal, TotalEnergies will supply the tech giant with 1 gigawatt of solar power for its data centers in Texas over a 15-year span.

However, the company also recently redirected nearly $1 billion in capital away from wind energy projects and "decided to renounce offshore wind development in the United States." Read more here.
