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."

4 student-led sustainability-focused startups scored funding at annual Houston competition

big winners

Four student-founded energy and sustainability startups from around the world have something to celebrate — cleaning up at the 24th annual Rice Business Plan Competition.

This year, 42 startups competed this year, participating in the three-day event that culminated in a reception on Saturday, April 6. Over a dozen companies won prizes, and the full recap of those is reported on InnovationMap.

“We award the competitors $1 million in prizes, prizes that serve as foundational capital to launch their startup,” RBPC Director Catherine Santamaria says at the awards gala. “That’s a large number of prizes, but the biggest thing our startups leave with is a feeling of generosity and community from this room. This community is always ready and willing to help our founders and support our vision for the competition by investing time, money and resources in these student innovators.”

The companies were divided into five categories — one of which was Energy, Cleantech and Sustainability. Four companies from that track scored prizes at the reception.

Icorium Engineering Company from the University of Kansas walked away with $171,000. The company — a chemical engineering startup developing technologies to make sustainable, circular economies a reality for refrigerants and other complex chemical mixtures — won fifth place and a $5,000 prize sponsored by Norton Rose Fulbright, EY, Chevron Technology Ventures and Shell Ventures, as well as:

  • $100,000 OWL Investment Prizes
  • $40,000 nCourage Courageous Women Entrepreneur Investment Prize
  • $25,000 from Finger Interests, the Anderson Family Fund at the Greater Houston Community Foundation, Greg Novak and Tracy Druce
  • $1,000 Anbarci Family Company Showcase Prize
  • Mercury Elevator Pitch Competition Prize (Best in Energy, Sustainability)
  • An invitation to Entrepreneur Magazine's elevator pitch show

From RWTH Aachen University in Germany, Power2Polymers secured $50,000. Tackling the challenge of forever chemicals, the company is creating safe alternatives free of forever chemicals. The German company took third place and the $50,000 investment sponsored by Finger Interests, the Anderson Family Fund at the Greater Houston Community Foundation, Greg Novak and Tracy Druce. The company also won the Mercury Elevator Pitch Competition Prize (Best Overall).

Two climatetech companies that didn't make it to the finals still walked away with funding. From Yale University, Oxylus Energy, which has a technology that uses renewable electricity to turn CO2 and water into energy-dense liquid fuels, won the $25,000 New Climate Ventures Sustainable Investment Prize.

LiQuidium, with its sustainable membrane technology for direct lithium extraction process, from the University of Houston also scored $25,000 — this one from NOV Energy Technology Innovation Cash Prize.

Houston AI energy forecasting company lands investment from Samsung Ventures

funding for forecasts

Amperon, a Houston-based AI-powered forecasting solutions company, has received an investment for an undisclosed amount from Samsung Ventures, the corporate venture arm of Samsung Group.

According to Amperon, the funding will be put toward the company's global growth and next-generation product development. Samsung Ventures invests in emerging businesses developing technologies for the AI, advanced devices and energy-related sectors.

“Samsung Ventures’ investment is a strong validation of our mission to transform the way energy is forecasted and traded,” Sean Kelly, CEO and co-founder of Amperon, said in a news release. “Samsung’s global footprint and leadership in semiconductors, data infrastructure, and AI acceleration make them a natural fit as we expand Amperon’s reach into energy-intensive sectors like data centers. Their track record of scaling next-generation technologies aligns perfectly with our vision to build a more intelligent, resilient, and data-driven energy system.”

Amperon was founded in 2018. Its AI models combine real-time weather, consumption and market data for energy retailers, utilities and independent power producers.

Last year, the company launched its weather-informed grid demand Mid-Term Forecast (MTF), which provides users with data on electricity demand up to seven months in advance. It also secured strategic investments from Acario, the corporate venture capital and innovation division of Tokyo Gas, as well as National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG).

After expanding into Europe in 2024, the company has continued to see international growth, and currently operates in the U.S., Canada, Mexico, Australia, Europe and the Middle East.

“Amperon has demonstrated strong technical capabilities and global traction in a rapidly evolving energy landscape,” a spokesperson for Samsung Ventures added in the release. “Their ability to forecast and model real-time energy data at global scale positions them as a key enabler of smarter energy systems and climate resilience. We are pleased to invest in a company developing technologies that support a more sustainable and digitized world.”

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
