Halliburton has again added a handful of energy tech startups to its Houston-based incubator.

Three companies — Matrix Sensors, Renew Power Systems, and SunGreenH2 — have joined Halliburton Labs as its newest clean energy participants.

“Companies across the energy landscape are interested in scalable innovations that improve the cost, reliability, and sustainability of energy,” says Managing Director Dale Winger in the news release. “Our tailored program combines expert support, access to a global network, and the physical resources for participants to scale. We’re excited to help these companies accelerate their market traction.”

Halliburton, a provider of energy equipment and services, launched Halliburton Labs in 2020. Last September was the incubator's last cohort addition. The next Halliburton Labs Finalists Pitch Day is Friday, January 27, at the Ion. The event will include pitches from 10 innovative, early-stage energy tech companies. 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.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.

Houston e-commerce giant Cart.com launches government-focused subsidiary

government branch

Houston e-commerce and logistics unicorn Cart.com has launched a new subsidiary.

Cart Government Solutions (CGS), which was announced earlier this week, will provide supply chain and logistics services and software for the federal and state government sectors. The new subsidiary will be headquartered in Washington, D.C., and operate out of about 6 million square feet of secure warehouse space across 14 U.S. facilities, according to a news release from Cart.com. It will support both domestic and overseas logistics.

Industry veteran Gregg Zegras will lead the new entity as president. Zegras previously served as Cart.com's chief revenue officer, according to LinkedIn. Before that, he served as president of Connecticut-based Pitney Bowes Global eCommerce, a digital shipping solutions company.

Remington Tonar, Cart.com's co-founder, will serve as CGS's chief innovation officer.

“Government agencies face procurement and logistics challenges that many commercial platforms simply weren’t built to solve,” Zegras said in the news release. “Cart Government Solutions exists to change that. We’re combining the speed and innovation of a technology company with the compliance rigor, security, and operational depth that federal and state customers require, and we’re doing it with a team that has spent careers working alongside and inside these agencies.”

According to the company, CGS will focus on meeting compliance and security requirements in the public sector. Some of the services the new entity will offer include:

  • Inventory management
  • Cold-chain and specialty storage for pharmaceuticals, medical devices and regulated goods
  • Enterprise-grade supply chain software
  • Government-compliant webstores and online ordering portals
  • Cybersecurity operations

Cart.com has been serving the public sector since 2022, when the company began distributing COVID-19 health supplies nationwide, according to the news release. Through that pandemic-era contract, the company reports it moved more than 725 million units, with an average of under two days per shipment.

Cart.com was founded in Houston in 2020, though it briefly moved its headquarters to Austin. The company reached unicorn status with its $60 million Series C raise in 2023. It most recently raised $180 million in growth capital from private equity firm Springcoast Partners in March, which put the startup over the $1 billion in fundraising mark in just six years.

At the time, Cart.com said it planned to scale its logistics network, expand AI capabilities and develop workflow automation tools.

Houston-based KBR Inc. also recently launched a government services spinoff. Read more here.

2 Houston universities named best colleges of 2027 by Princeton Review

A-Plus Ratings

Back-to-school season has returned in full force, and that means it's time for college rankings. Two Houston universities in particular are being hailed as the top of the class for 2027.

The high caliber schools — Rice University and University of Houston — earned new acclaim in The Princeton Review's ranking of the "Best 392 Colleges" for 2027.

The Princeton Review's 35th annual "Best Colleges" rankings are determined by a survey of 172,000 current college students that gave "candid feedback" about their schools and their experiences. The flagship guide does not rank the schools overall, but it does rank them across 50 different categories, including best-run colleges, best quality of life, happiest students, best athletic facilities, among others.

In all, 14 Texas institutions were highlighted in the overall list of the 392 best colleges.

Schools don't pay to be included in the guide, but The Princeton Review clarified that schools could pay for a "featured" designation. No Houston university paid to be featured in this year's guide. Trinity University in San Antonio and Southwestern University, a private school in the Austin suburb Georgetown, were the only two Texas schools that paid to be "featured."

Rice and UH have been on a winning streak in separate reports of the best universities worldwide, best graduate schools, and best online degree programs.

In addition to being included in the overall list, Rice was highlighted as one of the Best Value Colleges, Colleges That Create Futures, and it earned high marks in Princeton Review's Mental Health Honor Roll 2026. The home of the Rice Owls also starred in the regional Best Southwest list that contained 41 universities across Arizona, Colorado, New Mexico, Oklahoma, and Texas.

"Rice University stands out as a leading research university where academic diversity and a wide array of interdisciplinary institutes and centers make it easy for students to explore multiple areas of interest," the school's profile says. "At Rice, 'knowledge isn’t siloed — students are constantly crossing disciplines and interests in ways that feel natural rather than exceptional.'"

Rice earned the following rankings on 14 other lists:

  • No. 1 – Lots of Race/Class Interaction
  • No. 3 – Best College Newspaper
  • No. 9 – Friendliest Students
  • No. 11 – Best Quality of Life
  • No. 13 – Great Financial Aid
  • No. 14 – Top 50 Best Value Private Colleges
  • No. 17 – Their Students Love These Colleges
  • No. 18 – Top 20 Best Value Private Colleges Without Aid
  • No. 18 – Best Student Support and Counseling Services
  • No. 19 – Best College Dorms
  • No. 21 – Students Study the Most
  • No. 24 – Best Campus Food
  • No. 24 – Best College Radio Station
  • No. 24 – Best-Run colleges
The University of Houston also appeared in the Best Southwest, Best Value Colleges, and Colleges That Create Futures lists, and it was named a top Green College, which examined schools that "share superb sustainability practices, a strong foundation in sustainability education, and a healthy quality of life for students on campus



UH earned five more accolades:

  • No. 1 – Top 50 Undergraduate Schools for Entrepreneurship Studies
  • No. 1 – Top Undergraduate Schools for Entrepreneurship Studies in the Southwest
  • No. 8 – Most Politically Moderate Students
  • No. 15 – Financial Aid Not So Great
  • No. 42 – Top 50 Best Value Public Colleges
In the school's profile, students say they had an overall positive experience thanks to UH's excellent academic offerings and dedicated faculty members.

"Students confirm that 'the research and other academic opportunities... are very accessible to students who seek it out,'" the profile says. "This includes taking advantage of UH’s vast alumni network (more than 325,000 and counting), not to mention its location in the corporate center of Houston, where 'the opportunities that are provided are immense.'"

The 12 other public and private universities in Texas included in The Princeton Review's 2027 guide are:

  • The University of Texas at Austin
  • Southwestern University, Georgetown
  • Baylor University, Waco
  • Texas A&M University - College Station
  • Trinity University, San Antonio
  • Texas State University, San Marcos
  • Angelo State University, San Angelo
