At the 20th annual Energy Tech Venture Forum presented by Rice Alliance for technology and Entrepreneurship, 11 startups scored recognition from the event's investors who evaluated over 90 early-stage energy transition companies.

"The selection process was both exhilarating and challenging given the incredible ideas we've seen today," says Jason Sidhu, director of information services business engagement at TC Energy, who announced the top companies. "I want to extend my gratitude to every company that participate din this year's Energy Tech Venture Forum. Your commitment to solving energy problems and pursuing ambitions ideas is truly commendable."

In addition to the top 10 most-promising companies, the event's attendees decided the people's choice pick out of the 50 or so pitching companies. The winner of that recognition was Calgary, Alberta-based Galatea Technologies, which has created a tech platform to enhance workflows for operational, financial, and environmental performance.

The top companies, according to the Rice Alliance experts and investors, were:

  • Circular economy startup, Polystyvert. Based in Montreal, the company has created a unique dissolution recycling process that creates a material that can contribute to cutting carbon emissions by up to 90 percent.
  • United Kingdom-based Mirico provides a tracking technology to its customers to measure climate gases (like methane, carbon dioxide, nitrous oxide, and ammonia), across areas up to half a square mile and in all conditions.
  • Protein Evolution, from New Haven, Connecticut, taps into a combination of green chemistry and enzyme technology to break down synthetic polymers.
  • Another Canadian company, Ayrton Energy, based in Calgary, created a liquid organic H2 carrier (LOHC) storage technology presents an opportunity for large, scalable and efficient transport of H2 over long distances.
  • Also representing New Haven, Connecticut, Carbon Loop is on a mission to make carbon capture and conversion scalable through carbon dioxide electrolysis using a proprietary catalyst to convert captured carbon dioxide into methanol.d
  • Based in London, Mobilus Labs has designed a new way for frontline communication with an in-helmet hardware and software solution. software solution designed for the frontline workforce.
  • 1s1 Energy, based in California, is working on producing low-cost green hydrogen by creating new materials to unlock unprecedented electrolyzer efficiency, durability, and more.
  • From Skokie, Illinois, Numat is specializing in solutions within Metal-organic framework (MOF) research to enhance the process of separating the hazardous chemicals negatively impacting human health and the environment.
  • Mantel, headquartered in Cambridge, Massachusetts, created a molten borate technology to capture CO2 in a new and efficient way.
  • The lone Houston-based company, Mars Materials is working to produce acrylonitrile using CO2 and biomass to enable decarbonization applications in carbon fiber and wastewater treatment.

A $50 million federal grant will help Houston-based CenterPoint Energy strengthen Houston’s power grid.

The U.S. Department of Energy (DOE) grant will support power substation upgrades in the Houston area.

“Our mission is to build the most resilient coastal grid in the nation for the 2.9 million customers we proudly serve in the greater Houston area … [The grant] will directly fund industry-leading technology improvements that are expected to strengthen resiliency, reliability, and meet the growing energy needs of our region,” Jason Ryan, CenterPoint Energy’s executive vice president for regulatory services and government affairs, said in a release.

CenterPoint says the project will make it one of the first U.S. utilities to install Siemens Energy’s grid-stabilizing technology.

The project will create more than 500 construction and installation jobs, CenterPoint says.

“Generations of CenterPoint customers and families in the region will benefit from the advanced technology this grant is funding,” said Kathleen Jackson, a member of the Public Utility Commission of Texas. “And any time companies make improvements like this to their systems, the long-term impact is making the entire grid stronger for Texans.”

The $176.7 million substation project is part of CenterPoint’s Greater Houston Resiliency Initiative, which launched in 2024.

So far, the initiative has:

  • Installed nearly 82,400 storm-resilient poles and equipment
  • Trimmed and cleared more than 13,700 miles of trees and vegetation near power lines
  • Added nearly 820 grid automation and intelligence devices
  • Put more than 880 miles of power lines underground

The initiative kicked off three years after Winter Storm Uri. CenterPoint received harsh criticism for what customers complained was the utility’s slow response to the 2021 storm. Uri caused a massive power outage and at least 246 deaths across Texas.

CenterPoint blamed the Electric Reliability Council of Texas (ERCOT), which operates the power grid for most Texans, for not supplying the utility with enough electricity during and after the storm.
