Registration is open for the event.

Here are details, according to Halliburton, about the three new startups at the incubator.

Matrix Sensors

Using a new class of gas-adsorbing materials known as metal-organic frameworks to develop the world’s first quantitative gas sensor on a chip, Matrix Sensors has created a touch-free technology that enables advancements in sensor size, power, cost, and performance to address limitations of current gas sensor technologies, which require manual calibration every six months. The company is based in San Diego, California.

“With Halliburton’s global reach, we can apply our technology to some of the biggest problems facing the energy sector today, including CO2 sensors for energy efficient buildings and methane sensors for leak detection,” says Matrix Sensors CEO Steve Yamamoto in the release.

Renew Power Systems

RPSi, based in Minneapolis, Minnesota, is a clean-tech company that develops hardware and software solutions that enable flexible and sustainable grid infrastructure. RPSi uses power electronics to connect renewable energy resources, such as wind and solar, with each other and the grid.

“Our mission is to help change the way the world generates and distributes energy,” says CEO Zach Emond in the release. “With RPSi technology, a diverse range of domestic and global communities will benefit from the acceleration of renewable energy resources that work with new and existing grid infrastructure and improve access to affordable, sustainable, and resilient electricity.”

SunGreenH2

Singapore-based SunGreenH2 builds high-performance hardware for electrolyzer cells, stacks, and systems that increase hydrogen production, decrease energy use, and reduce platinum group metals use. The company supplies hardware components for alkaline and proton-exchange membrane electrolyzers. Its modular, high-efficiency anion exchange membrane (AEM) electrolyzer stack, which is being commercialized, uses renewable power to produce low-cost green hydrogen for industries, transport, and energy storage.

“We are excited to unlock the future of green hydrogen production. With the help of Halliburton’s engineering and manufacturing expertise, we plan to commercialize and roll out our product in major international markets,” says Tulika Raj, co-founder and CEO of the company, in the release.

Micro-nuclear reactor to launch at Texas A&M innovation campus in 2026

nuclear pilot

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan.

Washington, D.C.-based Last Energy will build a 5-megawatt reactor that’s a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid.

The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy’s first installation of a nuclear reactor in the U.S.

Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system’s board of regents, said is “an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.”

Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus.

The project is “bold, it’s forward-looking, and it brings together private innovation and public research to solve today’s energy challenges,” Hegar said.

As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in “the next atomic era.”

In February, John Sharp, chancellor of Texas A&M’s flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid.

Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.

Houston falls from top 50 in global ranking of 'World's Best Cities'

Rankings & Reports

Houston is no longer one of the top 50 best cities in the world, according to a prestigious annual report by Canada-based real estate and tourism marketing firm Resonance Consultancy.

The newest "World's Best Cities" list dropped Houston from No. 40 last year to No. 58 for 2026.

The experts at Resonance Consultancy annually compare the world's top 100 cities with metropolitan populations of at least 1 million residents or more based on the relative qualities of livability, "lovability," and prosperity. The firm additionally collaborated with AI software company AlphaGeo to determine each city's "exposure to risk, adaptation capacity," and resilience to change.

The No. 1 best city in the world is London, with New York (No. 2), Paris (No. 3), Tokyo (No. 4), and Madrid (No. 5) rounding out the top five in 2026.

Houston at least didn't rank as poorly as it did in 2023, when the city surprisingly plummeted as the 66th best city in the world. In 2022, Houston ranked 42nd on the list.

Despite dropping 18 places, Resonance Consultancy maintains that Houston "keeps defying gravity" and is a "coveted hometown for the best and brightest on earth."

The report cited the Houston metro's ever-growing population, its relatively low median home values ($265,000 in 2024), and its expanding job market as top reasons for why the city shouldn't be overlooked.

"Chevron’s shift of its headquarters from California to Houston, backed by $100 million in renovations, crowns relocations drawn by record 2024 Port Houston throughput of more than four million containers and a projected 71,000 new jobs in 2025," the report said.

The report also draws attention to the city's diversity, spanning from the upcoming grand opening of the long-awaited Ismaili Center, to the transformation of several industrial buildings near Memorial City Mall into a mixed-use development called Greenside.

"West Houston’s Greenside will convert 35,000 square feet of warehouses into a retail, restaurant and community hub around a one-acre park by 2026, while America’s inaugural Ismaili Center remains on schedule for later this year," the report said. "The gathering place for the community and home for programs promoting understanding of Islam and the Ismaili community is another cultural jewel for the country’s most proudly diverse major city."

In Resonance Consultancy's separate list ranking "America's Best Cities," Houston fell out of the top 10 and currently ranks as the 13th best U.S. city.

Elsewhere in Texas, Austin and Dallas also saw major declines in their standings for 2026. Austin plummeted from No. 53 last year to No. 87 for 2026, and Dallas fell from No. 53 to No. 78.

"In this decade of rapid transformation, the world’s cities are confronting challenges head‑on, from climate resilience and aging infrastructure to equitable growth," the report said. "The pandemic, long forgotten but still a sage oracle, exposed foundational weaknesses – from health‑care capacity to housing affordability. Yet, true to their dynamic nature, the leading cities are not merely recovering, but setting the pace, defining new paradigms of innovation, sustainability and everyday livability."

Waymo self-driving robotaxis will launch in Houston in 2026

Coming Soon

Houston just cleared a major lane to the future. Waymo has announced the official launch of its self-driving robotaxi service in the Bayou City, beginning with employee-only operations this fall ahead of a public launch in early 2026.

The full rollout will include three Texas cities, Houston, Dallas, and San Antonio, along with Miami and Orlando, Florida. Currently, the company operates in the San Francisco Bay Area, Phoenix, and Los Angeles, with service available in Austin and Atlanta through Uber.

Before letting its technology loose on a city, Waymo first tests the routes with human drivers. Once each locale is mapped, the cars can begin driving independently. Unique situations are flagged by specialists, and engineers evaluate performance in virtual replicas of each city.

“Waymo’s quickly entering a number of new cities in the U.S. and around the world, and our approach to every new city is consistent,” explained the announcement. “We compare our driving performance against a proven baseline to validate the performance of the Waymo Driver and identify any unique local characteristics.”

The launch puts Waymo ahead of Tesla. Elon Musk’s Austin-based carmaker has made a lot of hullabaloo about autonomy being the future of the company, but has yet to launch its service on a wide scale.

Waymo started testing San Antonio’s roadways in May as part of a multi-city “road trip,” which also included Houston. The company says its measured approach to launches helps alleviate local concern over safety and other issues.

“The future of transportation is accelerating, and we are driving it forward with a commitment to quality and safety,” Waymo wrote. “Our rigorous process of continuous iteration, validation, and local engagement ensures that we put communities first as we expand.”
