From fast-charging batteries and hydrogen fuel alternatives to metals recycling and artificial intelligence-driven data tools, energy tech startups have a lot to offer the industry.

After nearly 60 pitches, the Rice Alliance for for Technology and Entrepreneurship named 10 startups to look out for in the energy industry. The announcement was made at the conclusion of the annual Energy and Clean Technology Venture Forum hosted at Rice University on September 11.

Of the 10, five hail from Houston. Check out this year's energy tech startups to look out for.

Sensytec

Fresh off a win from Houston's inaugural MassChallenge Texas cohort, Houston-based Sensytec again scored big. Sesnsytec's technology is known as the "smart concrete" because they've created a device that can be embedded into concrete and monitor its structure in real time. The company was founded out of the University of Houston in 2016 by Ody de la Paz.

Rheidiant

Another Houston-based company, Rheidiant uses industrial Internet of Things to optimize data from the pipelines. As a result, Rheidiant's technology can increase productivity, reduce leaks, quickly respond in emergency situations, and enhance visibility in the field. Rheidiant was founded in 2014 by CEO Murat Ocalan.

Nesh

Houston-based Nesh has created a smart assistant for oil and gas. Using artificial intelligence, Nesh can answer any question from an oil and gas employee to improve their decision-making process and cut down on the time it takes to find solutions. Nesh was founded in 2018 by Sidd Gupta and the company closed its seed round in April.

GBatteries

GBatteries, based in Ottawa, Canada, is changing the lithium battery charging game. With a mission of revolutionizing the electric car industry, GBatteries has created an artificial intelligence-backed technology that can charge a lithium battery to half full in 5 minutes. The company has 10 patents granted and 28 pending and has pilot programs in the works with automotive companies.

HARBO Technologies

Tel Aviv, Israel-based HARBO Technologies bills itself as the fastest and most effective oil spill response system in the world.The company's T-Fence system can be deployed quickly and by a team of as little as two people. HARBO was founded in 2013 by CEO Boaz Ur and has raised three rounds of funding, according to Crunchbase.

Sensorfield

It's not the first time Houston-based Sensorfield has been deemed most promising by the Rice Alliance. The company has created easy to install, wireless devices for monitoring throughout the industrial process. In May, the startup was selected for Chevron Technology Ventures' Catalyst Program.

MolyWorks Materials Corp.

California startup, MolyWorks Materials Corp., is improving the way industrial materials are recycled by building by creating a network of distributed recycling and additive manufacturing. Old metals materials go in, and metallic powder for manufacturing new products come out.

Lilac Solutions

Oakland, California-based Lilac Solutions exists to enhance lithium production as the demand rises with the growth of the electronic vehicles industry. Lilac has created a unique ion exchange technology that can lower the cost of lithium production while increasing the speed. The company is currently operating pilot programs.

Mission Secure

Mission Secure Inc. has created an industrial control system that can protect energy companies from potential cybersecurity threats as well as educate on the process. Based in Charlottesville, Virginia, MSI is venture backed and serving clients in Houston.

Syzygy Plasmonics

Houston-based Syzygy Plasmonics is fresh off a $5.8 million series A funding round it closed in August. The company is creating a hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions. The hydrogen-fueled technology originated out of research done over two decades by two Rice University professors, Naomi Halas and Peter Nordlander. Earlier this summer, the Rice Alliance named Syzygy a most promising startup at the Offshore Technology Conference.

Oxy's $1.3B Texas carbon capture facility on track to launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.

New app by Sports Illustrated grants access to 700 sports courts in Houston

Goal!

A new sports center booking app CatchCorner, powered by Sports Illustrated, enables sports enthusiasts in Houston to seamlessly secure a spot for a quick game without membership fees.

It soft-launched in Houston this spring and, according to co-founder and chief operating officer Maya Azouri, has been a huge success.

"The Houston expansion has been jaw-dropping," she said. "Up until now, CatchCorner’s launch in New York City had been our most successful market, but Houston has launched on par with it."

Within a 30-day period this summer, over 30,000 users join the app, Azouri noted, adding that the app would include 700 unique recreational spaces users can choose from in the city.

"There’s a real sports culture here, with athletes of all levels from casual weekend players to competitive amateurs and even pros. The diversity of the sports community, combined with the number of high-quality facilities across the city, makes it a perfect fit for CatchCorner," she said.

CatchCorner in Houston offers bookings for basketball, volleyball, soccer, pickleball, padel, baseball, badminton, and tennis, with plans to include golf simulators and ice rink sports soon. The Zone Sports, Toros HTX, PAC Gym, and Houston Pickleball Center are among the most popular venues.

Using the app is a snap. Once you pick your sport, venues with available slots are listed including distance from you with the booking schedules in the results so there are no surprises. The slots can go fast, so occasional error messages pop up when trying to book, but it's otherwise a three-click process. CatchCorner also helpfully includes a picture of the facilities while booking.

CatchCorner announced Google integration in June that lets users book through the app directly from searches when they look up specific venues. This is slightly less intuitive to use than the app, but it does ultimately work in both mobile and desktops versions. Either way, it greatly streamlines the booking process for people who just want to schedule a quick pickup game somewhere.

"It’s especially useful for casual players or people who want to organize something on short notice," said Azouri. "Whether it’s a weekend basketball run, a weekday futsal match, or a spontaneous pickleball game with friends, CatchCorner makes it easy to coordinate without the usual logistical headaches.

"Some feedback here has been that we’re like 'Expedia for sports.' It’s because booking a flight online is that easy, booking your next game or workout should be just as simple."

10 Houston billionaires make Forbes' list of richest Americans in 2025

The Rich List

America's wealthiest billionaires are $1.2 trillion richer in 2025, bringing their collective worth to a staggering $6.6 trillion. And Houston's own Richard Kinder has become the richest billionaire in the city, according to the new Forbes 400.

The Kinder Morgan chairman is the 11th richest Texas resident and ranks as the 108th richest American. Kinder also dethroned Tilman Fertitta to claim the title as the wealthiest Houstonian.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies.

Kinder's wealth

The publication estimates Kinder's net worth at $10.6 billion, up from $8.1 billion last year. He also appears among Forbes' separate list of the richest billionaires in the world.

"It’s been a year unlike any we’ve seen in the four decades we’ve tracked America’s billionaire class,” said Forbes senior editor Chase Peterson-Withorn in a press release. "The super-rich at the very top are richer than ever — and between the White House and the booming stock market, they’re as powerful as they’ve ever been."

Kinder, 80, co-founded oil and gas pipeline firm Kinder Morgan in 1997, which is now known as one of the largest American energy infrastructure companies. He stepped down as CEO in 2015, though he still chairs the board of directors.

Kinder and his wife, Nancy, also founded Houston-based nonprofit the Kinder Foundation in 1997. The organization provides "major gifts to public causes with the intention of helping people realize healthy and rewarding lives," according to its website.

In May 2025, the Kinders pledged $150 million to Texas Children's Hospital and MD Anderson to create the Kinder Children's Cancer Center.

"Our philanthropic efforts center on supporting transformational projects in Houston, and this initiative exemplifies that mission in every way," said Kinder in a press release. "We were deeply impressed by the extraordinary leadership and unwavering commitment of both UT MD Anderson and Texas Children’s to pursue a bold, collaborative model of care. It is a rare and powerful moment when two leading organizations come together to create something entirely new – something capable of reshaping the future of pediatric cancer care."

The richest Houstonians

In all, 43 Texas billionaires made it on the 2025 Forbes 400 list, and 10 are based in the Houston metro.

Hospitality honcho Fertitta, 68, is the second-richest billionaire in Houston, and his net worth has jumped from $10.1 billion last year to $11 billion in 2025. He owns the Golden Nugget Casinos, the Houston Rockets, Texas-based restaurant and entertainment company Landry's, and also serves as the U.S. Ambassador to Italy.

"Serving as President Trump's ambassador to Italy 'is a real job,' says Fertitta, who personally oversaw the renovation of Villa Taverna, the ambassador's residence in Rome," Forbes wrote in his profile.

Fertitta most recently put his ritzy 250-foot-long superyacht on the market for about $192 million, with Forbes saying he "has a bigger one on order."

Here's how the rest of Houston's billionaires fared on this year's list:

Oil tycoon Jeffery Hildebrand ties for No. 123 nationally with an estimated net worth of $10 billion. Last year: $7.6 billion.
Toyota mega-dealer Dan Friedkin ranks 128th nationally with an estimated net worth of $9.7 billion. Last year: $7.6 billion.
Houston pipeline heir Randa Duncan Williams ranks 130th with an estimated net worth of $9.5 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 135th nationally. Each has an estimated net worth of $9.4 billion. Scott Duncan ranks No. 141 with a $9.2 billion estimated net worth.
Houston Texans owner Janice McNair ranks 201st nationally with an estimated net worth of $7.3 billion. Last year: $6.2 billion.
Energy exploration chief exec George Bishop of The Woodlands ranks No. 325 with an estimated net worth of $4.7 billion. Last year: $5 billion.

Richest billionaires elsewhere in Texas

The richest person in America in 2025 is none other than Austin-based Elon Musk. Musk, 54, saw his net worth skyrocket to $428 billion this year, or $184 billion more than his 2024 net worth. He claimed the No. 1 spot for the fourth time.

Walmart heiress Alice Walton of Fort Worth was dubbed the wealthiest woman in America for 2025. Walton, 75, simultaneously holds the title as the richest woman in the world. Forbes estimates Walton's net worth at $106 billion (up from $89.2 billion last year) and proclaims her as the first female centibillionaire (a person with a 12-digit fortune) in America. Now that's wealth.

"Tariffs. Inflation. Slowing employment. None of it has hit the fortunes of America’s billionaires," Forbes said. "A decade ago, when it took $1.7 billion to make The Forbes 400, a net worth of $3.8 billion was comfortably within the top half of the ranking — now that lofty sum is the minimum required."
