Nearly 100 energy tech startups pitched at the 19th annual Rice Alliance Energy Tech Venture Forum this week — and over a third of those companies are based in the Houston area.

At the conclusion of the event — which took place on Thursday, September 15, at Rice University, and included a day full of company pitches, panels, and thought leadership — 10 startups were deemed the most promising among their peers. The group was voted on by investors attending office hours ahead of the event.

The Rice Alliance for Technology and Entrepreneurship facilitated nearly 700 meetings between 70 investor groups and 90 ventures, according to the organization. The group of presenting companies included participants from Rice's Clean Energy Accelerator's first two cohorts.

Here are 10 of the energy tech industry's most promising companies — and the technology they are working on that's set to disrupt the status quo.

Arolytics

Based in Calgary and founded in 2018, Arolytics is a software company that specializes in emissions management, ESG performance, and regulatory compliance. The company's platform is able to save its users up to 40 percent of their associated measurement costs and emissions management.

Atargis Energy

Atargis Energy is based in Pueblo, Colorado, and is a a member of Rice's second cohort of its Clean Energy Accelerator. The company has developed a twin hydrofoil-based wave energy converter that creates electric power from ocean waves. The technology is paired with real-time sensors and machine learning to optimize power conversion.

Compact Membrane Systems

Based in Delaware, Compact Membrane Systems, is pioneering membrane systems for decarbonizing hard-to-abate chemical manufacturing and industrial carbon capturing. The technology has the potential to revolutionize the chemicals industry.

Dimensional Energy

Dimensional Energy, based in Ithaca, New York, is transforming carbon dioxide into sustainable aviation fuels and products at market competitive prices. The technology integrates carbon capture, electrolysis, and Fischer Tropsch synthesis.

9 Houston universities boast best grad programs of 2026, per U.S. News

making the grade

Nine Houston-area universities are earning new national acclaim in a report of the best graduate schools in the U.S. for 2026.

U.S. News & World Report annually publishes its national "Best Graduate Schools" rankings in early April, which comprehensively rank graduate programs across business, education, engineering, law, health, and many others.

New for the 2026 edition, the publication updated its rankings across 12 health disciplines — only physician assistant and social work were excluded — and "the first full refresh" of doctoral science programs since 2022. U.S. News also revived its Master's in Fine Arts rankings for the first time since 2020.

"We know a graduate degree is a major commitment,” said LaMont Jones, Ed.D., managing editor of Education at U.S. News. “That is why we are dedicated to methodologies that thoroughly examine a wide range of factors, from research excellence to career success. These rankings are a powerful tool for prospective students, offering clarity and confidence as they approach their most critical educational choice."

This is how the nine local schools ranked, statewide and nationally, and how they compared with last year's national ranking:

Houston medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.

Houston geothermal unicorn Fervo officially files for IPO

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.
