Wondering what energy tech companies you should keep an eye on? Wonder no more.

As a part of 2021 CERAWeek by IHS Markit, the Rice Alliance for Technology and Entrepreneurship hosted a virtual pitch competition today featuring 20 companies in four sessions. Each entrepreneur had four minutes to pitch, and then a few more to take questions from industry experts.

"Of the companies here today, we've intentionally selected a diverse group," says Brad Burke, managing director of the Rice Alliance at the start of the event. "They range from companies looking for their seed funding to companies that have raised $20 million or more."

The following companies pitched at the event: Acoustic Wells, ALLY ENERGY, Bluefield Technologies, Cemvita Factory, Connectus Global, Damorphe, Ovopod Ltd., DrillDocs, GreenFire Energy, inerG, Locus Bio-Energy Solutions, Nesh, Pythias Analytics, REVOLUTION Turbine Technologies, Revterra, ROCSOLE, Senslytics, Subsea Micropiles, Syzygy Plasmonics, Transitional Energy, and Universal Subsea.

At the end of each session, attendees voted via Zoom poll on which startup had the most potential. According to the event attendees, the most promising energy tech companies are:

REVOLUTION Turbine Technologies

Asheville, North Carolina-based REVOLUTION Turbine Technologies, an inaugural Greentown Houston member company, is working to "put a green spin on power." The company's micro-Expansion Turbine System produces green power for digital oilfield and pipeline initiatives through the recovery of excess natural gas pressure.

"RTT's technology provides a scalable, clean energy source to reliably power digital oilfield and pipeline initiatives at a significantly low operating cost," says Christopher Bean, founder and CEO, in his presentation. "Never has it been more important to make production and pipeline operations greener, safer, and efficient."

Connectus Global

Connectus Global, based in Calgary, provides custom technology solutions that can increase productivity, profits, and competitiveness. Connectus' Real-Time Location System, or RTLS, uses Ultra-Wide Band for communication and triangulation while hosting a Radio Frequency Identification Device, which come in the form of badges, tags, and receivers.

"In our first year, we received $800,000 in revenue and are on track to hit our numbers — $3.6 million — at the end of this fiscal year," says Mike Anderson, CEO of the company, in his presentation." We have a global white labeling agreement with Honeywell and we make up about 75 percent of their digitized workforce management portfolio."

The company's U.S. office is located in Houston.

DrillDocs

Houston-based DrillDocs has created an automated drilling cuttings characterization service, called CleanSight, that supports an operator's understanding of their wellbore's state of stability and cleanness in real time.

"We're taking computer vision to the drilling rig," says Calvin Holt, CEO and co-founder at DrillDocs, in his presentation. "Now for the first time, drilling and geomechanics teams will have unique, real-time data to ascertain the well's condition."

Revterra

Revterra, a Houston-based company and inaugural Greentown Houston member company, is creating a flywheel energy storage system for long-duration grid-scale applications.

"For those of us in Texas, the power outages we experienced a couple weeks ago are a stark reminder that the stability and the resiliency of our electric grid should be a top priority as we transition to low-emission power sources," says Ben Jawdat, founder and CEO at Revterra, in his presentation. "Energy storage is a critical element in both grid stability and enabling our transition to sustainable energy."

5 can't-miss innovation events at CERAWeek featuring Houston speakers

where to be online

While usually hundreds of energy experts, C-level executives, diplomats, members of royal families, and more descend upon Houston for the the annual CERAWeek by IHS Markit conference, this year will be a little different. Canceled last year due to COVID-19, CERAWeek is returning — completely virtually.

The Agora track is back and focused on innovation within the energy sector. The Agora track's events — thought-provoking panels, intimate pods, and corporate-hosted "houses" — can be accessed through a virtual atrium.

Undoubtedly, many of the panels will have Houston representatives considering Houston's dominance in the industry, but here are five innovation-focused events you can't miss during CERAWeek that feature Houstonians.

Monday — New Horizons for Energy & Climate Research

The COVID-19 pandemic has made vivid and real the risks of an uncontrolled virus. Risks posed by climate change are also becoming more palpable every day. At the forefront of understanding these risks, universities are developing solutions by connecting science, engineering, business, and public policy disciplines. Along with industry and governments, universities are critical to developing affordable and sustainable solutions to meet the world's energy needs and achieve net-zero emission goals. Can the dual challenge of more energy and lower emissions be met? What is some of the most promising energy and climate research at universities? Beyond research, what are the roles and responsibilities of universities in the energy transition?

Featuring: Kenneth B. Medlock, III, James A. Baker, III, and Susan G. Baker Fellow In Energy And Resource Economics, Baker Institute and Senior Director, Center For Energy Studies at Rice University

Catch the panel at 1 pm on Monday, March 1. Learn more.

Tuesday — Conversations in Cleantech: Powering the energy transition

With renewables investment outperforming oil and gas investment for the first time ever in the middle of a pandemic, 2020 was a tipping point in the Energy Transition. Low oil prices intensified energy majors' attention on diversification and expansion into mature and emerging clean technologies such as battery storage, low-carbon hydrogen, and carbon removal technologies. Yet, the magnitude of the Energy Transition challenge requires an acceleration of strategic decisions on the technologies needed to make it happen, policy frameworks to promote public-private partnerships, and innovative investment schemes.

Three Cleantech leaders share their challenges, successes, and lessons learned at the forefront of the Energy Transition. What is their vision and strategy to accelerate lowering emissions and confronting climate change? Can companies develop clear strategies for cleantech investments that balance sustainability goals and corporate returns? What is the value of increasing leadership diversity for energy corporations? Can the Energy Transition be truly transformational without an inclusive workforce and a diverse leadership?

Featuring: Emily Reichert, CEO of Greentown Labs, which is opening a location in Houston this year.

The event takes place at 11:30 am on Tuesday, March 2. Learn more.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

Houston clean energy co. secures $100M to deploy tech on global scale

Going Global

Houston-based Utility Global has raised $100 million in an ongoing Series D round to globally deploy its decarbonization technology at an industrial scale.

The round was led by Ara Partners and APG Asset, according to a news release. Utility plans to use the funding to expand manufacturing, grow its teams and support its commercial developments and partnerships.

“This financing marks a critical step in Utility’s transition from a proven technology to full-scale global commercial execution,” Parker Meeks, CEO and president of Utility Global, said in the release. “Industrial customers are no longer looking for pilots or promises; they need deployable solutions that work within existing assets and deliver true economic industrial decarbonization today that is operationally reliable and highly scalable. Utility’s technology produces both economic clean hydrogen and capture-ready CO2 streams, and this capital enables us to scale and deploy that impact globally with speed, discipline, and rigor.”

Utility Global's H2Gen technology produces low-cost, clean hydrogen from water and industrial off-gases without requiring electricity. It's designed to integrate into existing industrial infrastructure in hard-to-abate assets in the steel, refining, petrochemical, chemical, low-carbon fuels, and upstream oil and gas sectors.

“Utility is tackling one of the most difficult challenges in the energy transition: decarbonizing hard‑to‑abate industrial sectors,” Cory Steffek, partner at Ara Partners and Utility Global board chair, said in the release. “What sets Utility apart is its ability to compete head‑to‑head with conventional fossil‑based solutions on cost and reliability, even as it materially reduces emissions. With this new funding, Utility is well-positioned for its next chapter of commercial growth while maintaining the technical excellence and capital discipline that have defined its development to date.”

Utility Global reached several major milestones in 2025. After closing a $53 million Series C, the company agreed to develop at least one decarbonization facility at an ArcelorMittal steel plant in Brazil. It also signed a strategic partnership with California-based Kyocera International Inc. to scale global manufacturing of its H2Gen electrochemical cells.

The company also partnered with Maas Energy Works, another California company, to develop a commercial project integrating Maas’ dairy biogas systems with H2Gen to produce economical, clean hydrogen.

"These projects were never intended to stand alone. They anchor a deep and growing pipeline of commercial projects now in development globally across steel, refining, chemicals, biogas and other hard-to-abate sectors worldwide, Meeks shared in a 2025 year-in-review note. He added that 2026 would be a year of "focused acceleration to scale."

Houston Methodist awarded $4M grant to recruit head of Neal Cancer Center

new hire

Armed with a $4 million state grant, the Houston Methodist Academic Institute has recruited a renowned expert in ovarian and endometrial cancer research to lead the Dr. Mary and Ron Neal Cancer Center.

The grant, provided by the Cancer Prevention and Research Institute of Texas, enabled the institute to lure Dr. Daniela Matei away from Northwestern University’s Feinberg School of Medicine in Chicago. There, she is the Diana Princess of Wales Professor in Cancer Research and chief of the Division of Reproductive Science in Medicine.

Matei will succeed Dr. Jenny Chang, who was hired last year to run the Houston Methodist Academic Institute.

At the Neal Cancer Center, located in the Texas Medical Center complex, oncologists work on innovations in cancer research, treatment, and technology. The center opened in 2021 after the Neals donated $25 million to expand Houston Methodist’s cancer research capabilities. It handles about 7,000 new cases each year involving more than two dozen types of cancer.

U.S. News & World Report puts Houston Methodist Hospital at No. 19 among the country’s best hospitals for cancer care, two spots below Chicago’s Northwestern Memorial Hospital. The University of Texas MD Anderson Cancer Center in Houston sits at No. 1 on the list.

Matei’s research related to ovarian and endometrial cancer holds the potential to benefit tens of thousands of American women. The American Cancer Society estimates:

  • 21,010 women in the U.S. will be diagnosed with ovarian cancer, and 12,450 women will die from it.
  • 68,270 women in the U.S. will be diagnosed with endometrial cancer, and 14,450 women will die from it.

Matei is leaving Northwestern in the wake of widespread cuts in federal funding for medical research. The National Institutes of Health (NIH) has canceled or frozen tens of millions of dollars in grants for Northwestern, the Wall Street Journal reports, and the university has been plugging the gaps with its own money.

“The university is totally keeping us on life support,” Matei told the newspaper last year. “The big question is for how long they can do this.”

According to the Wall Street Journal, Matei’s $5 million NIH grant supporting 69 cancer trials has been caught up in the federal funding chaos, so Northwestern stepped in to cover trial expenses such as nurses’ salaries and diagnostic procedures.

Trial participants include some patients with rare, incurable tumors who are undergoing experimental treatments aligned with the genetics of their condition, the newspaper says.

“It’s certainly a life-and-death situation for cancer patients on these trials,” Matei said in 2025.

Matei is among the beneficiaries of more than $15 million in grants approved February 18 by CPRIT’s board. The grants went toward recruiting five cancer researchers to institutions in Texas.

One of those grants, totaling $1.5 million, went to the University of Houston to recruit Akash Gupta, a research scientist at MIT’s Koch Institute for Integrative Cancer Research. The remaining grants went to recruit scientists to The University of Texas at Dallas and The University of Texas Southwestern Medical Center.
