The Rice Alliance for Technology and Entrepreneurship, the Houston Energy Transition Initiative and the Texas Entrepreneurship Exchange for Energy announced the 30-plus energy ventures and five student teams that will pitch at the 2025 Energy Venture Day and Pitch Competition during CERAWeek next month.

The ventures are focused on driving efficiency and advancements toward the energy transition and will each present a 3.5-minute pitch before a network of investors and industry partners during CERAWeek's Agora program.

The pitch competition is divided up into the TEX-E university track, in which Texas student-led energy startups compete for $50,000 in cash prizes, and the industry ventures track.

Teams competing in the TEX-E Prize track include:

  • ECHO
  • HEXAspec
  • HydroStor Analytics
  • Nanoborne
  • Pattern Materials

The industry track is subdivided into three additional tracks, spanning materials to clean energy and will feature 36 companies. The top three companies from each industry track will be named. The winner of the CERAWeek competition will also have the chance to advance and compete for the $1 million investment prize at the Startup World Cup in October 2025.

Teams come from around the world, including several notable Houston-based ventures, such as Corrolytics, Rheom Materials, AtmoSpark Technologies, and others. Click here to see the full list of companies and investor groups that will participate.

The pitch competition will be held Wednesday, March 12, at CERAWeek from 1-4:30 pm. An Agora pass is required to attend.

Those without passes can catch more than 50 companies at a free pitch preview at the Ion. Pitches will be followed by private meetings with venture capitalists, corporate innovation groups, industry leaders, and tech scouts. The preview will be held Tuesday, March 11, from 9:30 am to 2:30 pm at the Ion. It's free to attend, but registration is required. Click here to register.

Last year, Houston-based Solidec took home the top TEX-E price and $25,000 cash awards. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions. Its co-founder and Rice University professor Haotian Wang was recently awarded the 2025 Norman Hackerman Award in Chemical Research.

Texas falls lower on national ranking of greenest states for 2025

room to improve

Texas dropped in the rankings on WalletHub's Greenest States 2025 report.

The report, released last month, considered 28 relevant metrics—from air and water quality to the number of alternative fuel stations and green buildings per capita—to call out states doing the best (and worst) jobs of caring for the environment.

Texas came in at No. 42 out of 50, with a total score of 42.54 out of 100. Last year, the Lone Star State ranked No. 38 with a score of 50.40 based on 25 metrics.

Texas' poor ranking was driven by its last-placed ranking, coming in at No. 50, for overall environmental quality. It was tied for No. 45 for air quality and ranked No. 46 for water quality, which helped comprise the overall environmental quality score.

Other metrics fell closer toward the middle of the pack. The state ranked No. 32 for eco-friendly behaviors and No. 39 for climate-change contributions.

California also fell on the annual report. While the state claimed the top spot in 2024, it came in at No. 7 this year. Vermont, which came in second in 2024, was named the greenest state in 2025.

Hawaii, which didn't crack the top five last year, was ranked No. 2 on the 2025 report. New York, Maryland and Maine rounded out the top five this year.

West Virginia was the country's least green state again this year, followed by Louisiana, Kentucky, Alabama and Mississippi.

The report also showed that Democrat-led states ranked around No. 12 on average, whereas Republican states fell at around No. 33.

While the WalletHub report seems bleak for Texas, others have shown more positive signs for the state. Texas was ranked slightly above average in a recent ranking of the best states for sustainable development. A recently released U.S. Energy Storage Monitor shows that Texas led all states and surpassed California in the fourth quarter of 2024 by installing 1.2 gigawatts of utility-scale energy storage for solar and wind power.

Still, WalletHub also recently ranked Houston No. 98 out of 100 of the largest cities on its Greenest Cities in America report. Read more here.

Houston renewables developer and Google agree to second solar collaboration

power purchase

EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.

Engie partners on major Texas, California battery storage portfolio

power partners

Houston’s Engie North America has partnered with New York-based CBRE Investment Management on a 2.4-gigawatt portfolio of battery storage assets in Texas and California.

The portfolio consists of 31 projects operating in the Electric Reliability Council of Texas (ERCOT) and California Independent System Operator (CAISO) territories. According to a company statement, the transaction represents one of Engie’s largest operating portfolio partnerships in the U.S.

“We are delighted that ENGIE and CBRE IM are partnering in this industry-leading transaction, supporting 2.4 GW of storage that will support the growing demand for power in Texas and California,” Dave Carroll, Chief Renewables Officer and SVP, ENGIE North America, said in the news release.

The deal is also one of the sector’s largest sales completed to date. Engie will retain a controlling share in the portfolio and will continue to operate and manage the assets.

“The scale of this portfolio reflects ENGIE’s commitments to meeting the energy needs of the U.S. and increasing the resilience of the ERCOT and CAISO grids,” Carroll added in the news release. “CBRE IM’s investment reflects their confidence in ENGIE’s proven track record in developing, building, operating and financing renewable assets, both in North America and globally.”

In North America, ENGIE currently has more than 11 gigawatts of renewable production and battery storage in operation or construction. Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. It also recently made a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

As of March 31, 2025, CBRE IM had $149.1 billion in assets under management and operated in 20 countries.

“We are excited to partner with ENGIE on this high-quality, scaled battery storage portfolio with a strong operating track record,” Robert Shaw, managing director, private infrastructure strategies at CBRE Investment Management, said in the release.
