CERAWeek announces winners of annual clean tech pitch competition

top teams

Teams from around the world and right here in Houston took home prizes at the fourth annual Energy Venture Day and Pitch Competition at CERAWeek on March 12.

The fast-paced event, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements toward the energy transition to present at 3.5-minute pitch before investors and industry partners during CERAWeek's Agora program. The competition is a qualifying event for the Startup World Cup, powered by Pegasus Venture, where teams compete for a $1 million investment prize.

The teams at this year's Energy Venture Day have collectively raised $435 million in funding.

Rice University student teams took home two of the three top prizes in the competition.

HEXASpec won the student track, known at TEX-E, taking home $25,000. The team's pitch focused on enhancing semiconductor chips’ thermal conductivity to boost computing power. Pattern Materials, another Rice-led team, claimed third place and won $10,000 for its proprietary LIG and LIGF technology that produces graphene patterns.

A team from the University of Texas McCombs School of Business, Nanoborne, took home second place and $15,000 for its engineering company focused on research and development in applied nanotechnology.

The companies that pitched in the three industry tracts competed for non-monetary awards. Here's who won:

Track A: Hydrogen, Fuel Cells, Buildings, Water, & Other Energy Solutions

Track B: Advanced Manufacturing, Materials, Fossil Energy, & Carbon Management

Track C: Industrial Efficiency, Decarbonization, Electricity, & the Grid

Arculus Solutions, which retrofits natural gas pipelines for safe hydrogen transportation, was named the overall winner and will move on to the Startup World Cup competition. California-based Membravo was also given a "golden ticket" to participate in the next NOV Supernova Accelerator cohort.

Teams at this year's Energy Venture Day represented five countries and 15 states. Click here to see the full list of companies and investor groups that participated.

New survey reveals concerns over AI data center growth in Houston

data findings

A new report out of the University of Houston shows that area residents remain wary of the long-term effects of operating data centers.

The recent survey from the University of Houston’s latest SPACE City Panel, conducted by the Center for Public Policy at the Hobby School of Public Affairs, shows that while 85 percent of Houston-area residents use AI, nearly 63 percent oppose the construction of AI data centers within 1 mile of their homes.

Respondents’ concerns centered around data centers’ high energy demand and the area’s power grid reliability. According to the survey, 32 percent of residents who oppose local data center projects would be more likely to support the centers if they relied on renewable energy over fossil fuels.

“Respondents understand that AI can bring economic and educational benefits, but they are also concerned about the physical infrastructure needed to fuel AI, especially data centers,” Soran Mohtadi, post-doctoral fellow at the Hobby School and a researcher on the report, said in a news release. “This physical infrastructure demands more electricity and water, leading to environmental impacts.”

Experts estimate that 6.5 gigawatts of data center capacity will be added to the Texas grid by 2030. And Houston’s data center capacity is predicted to more than double by 2028.

The Electric Reliability Council of Texas also projects electricity demand could reach 218 gigawatts by 2031, which would be more than double the record peak set in August 2023. Data centers are expected to account for 86 gigawatts of that new demand.

Survey respondents also said they are concerned about the state's future water supply, given the large amounts of water that data centers need to stay cool.

In terms of who’s responsible for that issue, 57.6 percent of respondents said they put the onus on Texas lawmakers, while 31.5 percent say tech companies should be responsible.

Additionally, more than 75 percent of respondents believed that data center developers and technology companies—not residents—should bear the cost of infrastructure upgrades to support data centers.

“Every decision legislators make has implications on residents’ everyday lives and local infrastructure now and in the future,” Maria P. Perez Arguelles, lead researcher on the report and research assistant professor at the Hobby School, added in the news release. “This issue is going to become more important in years to come, so this is just the beginning.”

American Airlines and Google ink record-breaking deal for cleaner jet fuel

SAF DEAL

Fort Worth-based American Airlines has sealed a record-breaking deal with tech giant Google to bolster the use of cleaner jet fuel.

The deal involves Google’s purchase of sustainable aviation fuel certificates tied to fuel that American will use at Chicago O’Hare International Airport, one of the airline’s hubs. These certificates enable companies like Google to pay for the environmental benefits of sustainable jet fuel without actually using the fuel.

American and Google say this is the largest publicly announced certificate deal between an airline and a corporate customer.

Google says environmental gains from the certificates will help it cut emissions from employees’ business travel.

The agreement covers 35 million gallons of sustainable aviation fuel over three years, resulting in a nearly 300,000 metric tons of carbon dioxide equivalent emissions. American has agreed to buy the fuel from San Antonio-based Valero.

“Our industry-leading agreement with Google is a critical step forward in reducing emissions from our operations,” Jill Blickstein, American’s chief sustainability officer, said in a news release. “By working with leaders like Google who share our commitment to innovation, we’re helping to grow demand for [cleaner jet fuel] and support the development of a stronger, more resilient market.”

Sustainable aviation fuel can reduce emissions by up to 80 percent compared with traditional jet fuel. It is made from feedstocks, like waste oil and fats, or it can be produced synthetically using captured carbon dioxide and renewable electricity.

The aviation industry accounts for about 2.5 percent of carbon dioxide emissions around the world, according to the International Energy Agency.

CenterPoint reports grid resilience updates as hurricane season begins

hurricane readiness

As hurricane season descends upon the region, CenterPoint Energy has shared the latest update on its Greater Houston Resiliency Initiative (GHRI) that’s been working to make grid upgrades and introduce weather-related tech since 2024.

As of April 2026, CenterPoint had:

  • Replaced more than 65,000 poles with stronger storm-resistant infrastructure
  • Trimmed or cleared more than 10,000 miles of vegetation
  • Undergrounded more than 500 miles of power lines
  • Installed more than 600 automation devices
  • Installed more than 150 weather stations

In May, CenterPoint announced its new Community Progress Tracker, which helps residents track electronic infrastructure improvements. In terms of other technology, CenterPoint has announced its partnership with weather, wildfire and flood modeling software Technosylva. The software is expected to help CenterPoint track weather conditions in advance to better prepare crews.

CenterPoint has also added 150 weather stations to improve weather monitoring, conducted a full-scale hurricane response exercise involving more than 400 employees and completed more than 25,000 hours of FEMA training across more than 800 employees. The company opened a new year-round Emergency Operations Center to help coordinate with emergency response partners, local and state officials, and media during major weather events.

“We are proud of the progress made in 2025, which helped deliver more than 100 million fewer outage minutes when compared to 2024, and we are determined to make even more progress in 2026 as we work toward our defining goal: building the nation's most resilient coastal grid,” Nathan Brownell, CenterPoint's vice president of resilience and capital delivery, previously said in a news release.

According to the company, the GHRI aims to improve overall grid resiliency and reliability and to reduce outages for customers. CenterPoint projects its efforts can reduce customer outages by 150 million by the end of 2026.
