For most of her career, Ana Amicarella has been the only person in the room who looks like her. But as CEO of Houston-based EthosEnergy, she's changing that.

"The energy sector for sure is highly dominated by men, but I think it's such an exciting environment," Amicarella says on the Houston Innovators Podcast. "What I try to do at every job that I go to is I try to increase representation — diverse representation and females in the company. And I measure that when I started and when I end. I want to be able to make a difference."

Amicarella joined EthosEnergy — which provides rotating equipment services and solutions to the power, oil and gas, and industrial markets — as CEO in 2019 a few years after it was in 2014 as a joint venture between John Wood Group PLC and Siemens Energy AG. Prior to her current role, she served in leadership roles at Aggreko an GE Oil and Gas. Read more.

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Houston-based Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth." Read more.

As Texans continue to invest in electric vehicles, public charging needs to be able to meet an increased demand, according to Chris George, the United States co-lead at Octopus Electric Vehicles, who wrote a guest column for InnovationMap about the state's potential when it comes to EVs.

"As we look to the future of transport and energy, the synergy between NEVI and Tesla’s network should create a compelling narrative for those thinking about leasing an EV," he writes. "Combine that with exciting new battery tech and potential range improvements, fueled by West Texas wind and solar, Texas is positioned to be a great state for the EV industry." Read more.

How this Houston business leader is promoting diversity, nimbleness amid energy transition

Houston innovators podcast episode 254

For most of her career, Ana Amicarella has been the only person in the room who looks like her. But as CEO of Houston-based EthosEnergy, she's changing that.

"The energy sector for sure is highly dominated by men, but I think it's such an exciting environment," Amicarella says on the Houston Innovators Podcast. "What I try to do at every job that I go to is I try to increase representation — diverse representation and females in the company. And I measure that when I started and when I end.

Prior to her current role, she served in leadership roles at Aggreko an GE Oil and Gas.

Recently, EthosEnergy announced it's being acquired by New York private equity firm, One Equity Partners, which Amicarella says is very interested in investing into EthosEnergy and its ability to contribute to the energy transition.

"What One Equity Partners will bring is tremendous decisiveness. They won't delay in deciding what is good for the company — I've already seen examples," Amicarella says, adding that the deal hasn't get been finalized. "They are going to make decisions and trust the management team, I think our pace of change will be enormous compared to what it used to be."

While EthosEnergy has customers from traditional oil and gas, she says she leads the company with the energy transition at the top of her mind, and that means being able to grow and evolve.

"One of the behaviors we look to have at EthosEnergy is an ability to be nimble," Amicarella says, "because we know market conditions change. Think of all the things we've had to go through in the last five years."

2 Houston universities excel on 2026 list of best U.S. colleges

Best in Class

Two top-tier Houston universities have been inducted into a new "hall of fame" list of the best colleges in the U.S. for 2026.

Rice University and the University of Houston were both praised in The Princeton Review's "The Best 391 Colleges: 2026 Edition."

Released August 12, the comprehensive guide annually ranks the best universities across 50 categories based on a survey of 170,000 current college students. Survey questions cover topics such as a school's academics and administration, student quality of life, politics, campus life, city life, extracurricular opportunities, and social environment.

The Princeton Review did not numerically rank the schools overall, but it does report the top 25 schools (out of the total 391) for each of the 50 different categories. The report also clarifies that while schools did not pay to be included in the guide, they could pay for a "featured" designation. Neither Houston university paid to be featured on the list.

Rice University, Houston's most prestigious private institution, appeared in the overall 391 best colleges list, and it also appeared in the regional "Best Southwest" list, the "Best Value Colleges" list, and the "Colleges That Create Futures" list. Rice's overall quality and its academic integrity are what students say are its greatest strengths. Students are additionally encouraged to think creatively — and even unconventionally — about how to approach course assignments.

"There's also an outside-the-box thinking when it comes to assessments, like 'the option to make a 30 minute scientific podcast instead of taking the final,' explains one sophomore," the school's profile says. "This isn't unusual for first-years either; one notes that 'instead of doing a bunch of writing and essays, I was tasked with creating...a TED Talk, which really lit a creative flame in me.'"

Rice students can brag about attending a school with the seventh best college newspaper and the 10th best college dorms and quality of life out of all colleges nationwide. The university's financial aid is also the ninth best in the country.

Here's how Rice fared in other Princeton Review rankings:

  • No. 14 – Top 50 Best Value Private Colleges
  • No. 14 – Lots of Race/Class Interaction
  • No. 17 – Best College Radio Station
  • No. 18 – Top 20 Best Value Private Colleges without Financial Aid
  • No. 19 – Best Science Lab Facilities
  • No. 23 – Best-Run Colleges
  • No. 25 – Students Study the Most

Rice has recently earned praise in a separate 2026 ranking of the best universities in the world, and its MBA program scored highly in The Princeton Review's 2025 best business schools list.

University of Houston also appeared in The Princeton Review's "Best Value Colleges," "Best Southwest," "Green Colleges," and "Colleges That Create Futures" lists. Students at this university also benefit from having the No. 1 undergraduate entrepreneurship program in the nation.

"Whether you're in or out-of-state, students consider their school to be 'not very expensive for the quality of education you're getting,' and the constant improvements help 'you feel like your degree is appreciating in value over time along with the school itself," the university's profile says.

Here's how University of Houston performed in other rankings:

  • No. 20 – Students Love Their School Teams
  • No. 21 – Scotch and Soda, Hold the Scotch (this list measured schools based on "the use of hard liquor" as reported by student surveys)
  • No. 22 – Cancel the Keg (this list measured "how widely beer is used" at schools based on student survey results)
  • No. 22 – Pot's Not Hot (this list ranked colleges with the "least marijuana usage based on ratings from real students about the popularity of marijuana on campus")
  • No. 25 – Most Politically Moderate Students
  • No. 42 – Top 50 Best Value Public Colleges
Unfortunately, UH ranked No. 11 in The Princeton Review's ranking of schools where financial aid is "not so great." However, there is plenty else to appreciate about this high performing university.

Other Texas universities included in The Princeton Review are:

  • University of Texas at Austin
  • Southwestern University in Georgetown
  • Texas State University in San Marcos
  • Trinity University in San Antonio
  • Texas A&M University in College Station
  • Angelo State University in San Angelo
  • Baylor University in Waco
  • Texas Christian University in Fort Worth
  • Southern Methodist University in Dallas
  • The University of Texas at Dallas in Richardson
  • University of Dallas in Irving
  • Austin College in Sherman

Intuitive Machines partners with Houston college for workforce training

space training

Intuitive Machines, a Houston-based space technology, infrastructure and services company, has forged a partnership with San Jacinto College to develop a program for training workers to handle biopharmaceutical materials delivered to Earth on Intuitive Machines’ re-entry vehicle.

Intuitive Machines is working with biotech company Rhodium Scientific on the project. Rhodium, also based in Houston, is developing biomanufacturing payloads for Intuitive Machines’ re-entry vehicle.

“Delivering life-improving pharmaceuticals from orbit is only valuable with reliable recovery and processes on Earth,” Tim Crain, chief technology officer at Intuitive Machines, said in a news release. “That requires more than a spacecraft — it demands the workforce, facilities, and regulatory alignment to support safe, repeatable operations. San Jacinto College has the credibility and technical depth to make this vision a reality.”

San Jacinto College provides training certified by the National Institute for Bioprocessing Research and Training. Christopher Wild, assistant vice chancellor and vice president of biotechnology at San Jacinto College, said that with this certification and the college’s presence at Houston Spaceport, the school “is uniquely positioned to train the workforce needed (for) commercial space-based pharma recovery.”

The first-phase grant supporting Intuitive Machines’ Earth re-entry program will culminate in a full-scale mockup tailored to real payloads and use cases in early 2026.

Intuitive Machines said the collaborations with San Jacinto College and Rhodium “aim to align future landing infrastructure, research opportunities, and funding pathways that deliver lasting economic impact from space.”
