Investors name most-promising energy tech startups at annual Houston event

big winners

Investors from around the world again identified the most-promising energy tech startups at the Rice Alliance for Technology and Entrepreneurship's annual event.

"The recognition that Houston is the epicenter of energy transition is growing. It's something we are championing as much as possible so that the world can know exactly what we're doing," Paul Cherukuri, chief innovation officer at Rice University says at the 21st annual Energy Tech Venture Forum.

The event took place during the inaugural Houston Energy and Climate Startup Week, and nearly 100 startups from 23 states and seven countries pitched investors Wednesday, September 11, and Thursday, September 12. At the conclusion of the event, the investors decided on 10 companies deemed "most promising" from the presentations.

This year's selected companies are:

  • Revterra, a Houston-based company innovating within kinetic battery technology to enable faster and cleaner electric vehicle charging.
  • From Austin, 360 Mining is a modular data center provider for the oil and gas producers.
  • New York company Andium is a centralized and optimized operations platform for large energy companies.
  • Elementium Materials, a local Katy-based company, created its battery technology that originated out of MIT.
  • Splight is a San Mateo, California-based technology platform that provides real-time operational data based on inverter-based resources assets.
  • Los Angeles-based Mitico, one of the Rice Alliance Clean Energy Accelerator's class 4 participants, provides services and equipment for carbon capture through its granulated metal carbonate sorption technology.
  • From Cambridge, Massachusetts, Osmoses is changing the way molecular gas separations are performed within the chemical, petrochemical, and energy industries.
  • Rice Alliance Clean Energy Accelerator class 4 participant CORROLYTICS, based in Houston, has a corrosion detection and monitoring technology. The company also won over the crowd and secured the People's Choice win too.
  • Ardent, based in New Castle, Delaware, has developed a membrane technology for point-source carbon capture.
  • New Haven, Connecticut-based Oxylus Energy produces an alternative fuel from converting CO2 into green methanol.

Last year, investors named its selection of most-promising companies at Rice.

"We have a responsibility as a city to lead energy transition," Cherukuri continues. "A lot of the investments we're making at Rice are going to change the world."

Woodlands-based Lancium teams up on West Texas data center campus

coming soon

The Woodlands-based Lancium Technologies, which designs, develops, and manages gigawatt-scale data center campuses, has teamed up with Denver-based data center builder and operator Crusoe Energy Systems on a new grid-connected campus more than 100 miles east of Wichita Falls.

Construction on the 1-gigawatt Childress County campus, being built for an unidentified tech company, is expected to start in Q3 of this year.

Lancium owns the 270-acre site where the data center campus will be located and will set up and manage the campus’ energy infrastructure. Crusoe will design, build, and operate the campus.

The two companies already are working together on data centers in Abilene. Their first data center has already expanded to a capacity of 1.2 gigawatts, and a 900-megawatt data center is planned for adjacent land owned by Lancium.

The Abilene project is the first site of the Stargate initiative, an AI infrastructure program backed by MGX, OpenAI, Oracle, and Softbank to create a U.S. network of hyperscale AI data centers. The four-year initiative has earmarked $500 billion to build the network.

“Childress is a natural next step in our partnership with Crusoe,” Lancium CEO Michael McNamara said in a news release. “Crusoe has been a great partner to build alongside in Abilene, and we’re glad to bring that same model — and the jobs and investment that come with it — to the community of Childress. We are deeply committed to working with local stakeholders to advance a model of development that addresses the broader needs of the community we will share for a very long time.”

Last year, Lancium appeared at No. 43 on Time and Statista’s list of America’s top greentech companies.

Lancium has raised $1.25 billion in funding since its founding in 2017, according to PitchBook and CB Insights.

In 2021, Lancium closed $150 million in funding led by Hanwha Solutions, with participation from SBI Holdings, Novawulf and other investors. Four years later, the company arranged $600 million in debt financing to advance development of “clean” data center campuses.

New York energy firm scoops up Houston’s Infinity Power Partners

m&a activity

Houston-based energy management and consulting firm Infinity Power Partners has been acquired by New York City-based Environ Energy, which also offers energy management and consulting services.

The deal creates a new “anchor segment” for Environ in the multifamily market. With the addition of Infinity Power’s roughly 2,000 clients in the multifamily sector, representing more than 1 million multifamily units under contract, Environ now has more than 8,000 U.S. clients in the commercial real estate, healthcare, manufacturing, education and government sectors.

“This acquisition continues to solidify our presence in key energy markets while aligning with founders who share our deep commitment to client success,” Environ CEO Chris Sternberg said in a news release.

Infinity Power co-founders and managing partners Nick Altman and Peter Selber have joined Environ, a portfolio company of investment firm 424 Capital. Altman and Selber founded Infinity Power in 2011.

“We built our business one relationship at a time,” Selber said, “with a strong commitment to the communities we serve. That same dedication is reflected in Environ’s approach — now delivered at scale.”

Altman says the acquisition is part of the “next chapter” in energy management. Energy management services help commercial customers reduce utility bills, improve equipment life, achieve green energy goals, and decrease risk tied to fluctuating energy prices.

“Energy management is a culture for continual improvement of energy performance and efficiency that’s integrated within an organization’s normal business practice,” according to the U.S. Office of Energy Efficiency & Renewable Energy.

In all, Environ has made six acquisitions in the past 17 months.

Last year, Environ acquired another Houston-based energy management and consulting firm, CSD Energy Advisors. In that deal, Environ gained nearly 1,000 clients, including several Fortune 500 companies and three large industrial energy users in Texas. As part of the deal, CSD co-founders Andrew Barth and JB Sowyrda joined Environ.

Also last year, Environ purchased Carrollton-based energy advisory firm Rapid Power Management (RPM).

Houston's PowerBridge partners on 2GW Texas AI data center campus

data center venture

Houston-based PowerBridge has formed a joint venture with Denver-based Liberty Energy to develop large-scale data center campuses.

The joint venture’s initial focus will be PowerBridge’s Alpha Digital Campus, a 2-gigawatt data center operation planned for West Texas. PowerBridge sets up data center campuses to support AI and cloud computing. Liberty is an energy company whose Liberty Power Innovations subsidiary offers distributed power and energy storage services.

Houston-based investment firm Five Point Infrastructure LLC established PowerBridge last year, committing up to $1 billion in equity. Earlier this month, The Wall Street Journal reported Five Point is trying to raise $2.5 billion for a new fund targeting water management projects, natural gas treatment systems and data center sites.

Through Five Point subsidiary LandBridge, PowerBridge enjoys access to more than 275,000 acres for infrastructure development as well as low-cost natural gas.

The first phase of PowerBridge’s West Texas campus is expected to offer more than 300 megawatts of generation capacity, with the potential to add more capacity over time. The campus is scheduled to start delivering power in the fourth quarter of 2027.

“By aligning our powered-campus development assets with Liberty’s comprehensive power services and operational expertise, we are creating a model that can be scaled across future gigawatt-scale powered data center campuses in West Texas,” Alex Hernandez, founder and CEO of PowerBridge, said in a release.

Before joining PowerBridge in 2025, Hernandez led Cumulus Data and Talen Energy Corp., a provider of power and energy infrastructure. Amazon Web Services bought Cumulus Data, a subsidiary of Houston-based Talen, in 2024 for $650 million. Cumulus develops nuclear-powered data centers.

Hernandez sits on the board of the Electric Reliability Council of Texas (ERCOT), which manages about 90 percent of the state’s electrical load.

Liberty recently announced a partnership with Houston-based energy technology company SLB to support the expansion of data center capacity.
