The student-led Rice Wind Energy team clinched second place overall at the U.S. Department of Energy’s 2025 Collegiate Wind Competition (CWC), which challenges students nationwide to design and build wind turbines, develop wind energy projects and engage in public outreach to promote renewable energy.

“The Collegiate Wind Competition is such an incredible opportunity for students passionate about sustainability to gain industry-applicable, hands-on experience in the renewable energy space,” senior and team vice president Jason Yang said in a news release.

The event was hosted by the National Renewable Energy Laboratories at the University of Colorado Boulder campus. Over 40 teams entered the competition, with just 12 advancing to the final stage. The competition comprises four core contests: connection creation, turbine design, turbine testing and project development.

Rice Wind Energy had the largest team with 26 students advancing to the final stage of the competition. It picked up a first-place win in the connection creation contest, and also placed third in the project development, fourth in turbine testing and fifth in turbine design contests.

“This accomplishment is a testament to our focus, teamwork and unwavering determination,” senior Esther Fahel, Rice Wind Energy’s 2024-25 president, said in a news release. “It’s a remarkable experience to have watched this team progress from its inception to the competition podium. The passion and drive of Rice students is so palpable.”

In the Connection Creation contest, the team hosted a wind energy panel with Texas Tech University, invited local high school students to campus for educational activities, produced a series of Instagram reels to address wind energy misconceptions and launched its first website.

The team also developed an autonomous wind turbine and floating foundation design that successfully produced over 20 watts of power in the wind tunnel. They were also one of just a few teams to complete the rigorous safety test, which brought their turbine to below 10 percent of its operational speed within 10 seconds of pressing an emergency stop button. It also designed a 450-megawatt floating wind farm located 38 kilometers off the coast of Oregon by using a multi-decision criteria matrix to select the optimal site, and conducted technical modeling.

“I am amazed at the team’s growth in impact and collaboration over the past year,” senior Ava Garrelts, the team’s Connection Creation lead for 2024-25, said in a news release. “It has been incredible to see our members develop their confidence by building tangible skills and lifelong connections. We are all honored to receive recognition for our work, but the entire experience has been just as rewarding.”

Rice faculty and industry sponsors included David Trevas and faculty advisers Gary Woods and Jose Moreto, Knape Associates, Hartzell Air Movement, NextEra Analytics, RWE Clean Energy, H&H Business Development and GE Vernova, Rice’s Oshman Engineering Design Kitchen, George R. Brown School of Engineering and Computing, Rice Engineering Alumni and Rice Center for Engineering Leadership.

The BYU Wind Energy Team took home the overall first-place prize. A team from the University of Texas at Dallas was the only other Texas-based team to make the 12-team finals.

Houston clean energy startup acquired by battery storage company FlexGen

m&a activity

A North Carolina company has acquired Houston-based Clean Energy Services, a provider of services for battery energy storage systems and utility-scale solar, for an undisclosed amount.

The buyer is Durham, North Carolina-based FlexGen Power Systems, a provider of battery energy storage software and services.

Clean Energy Services (CES), whose offices are at the Ion, will operate as a subsidiary of FlexGen. Existing CES customers will continue to receive services from CES without disruption or change, FlexGen says.

“Demand for reliable, high-performance power is accelerating, and customers need partners who can deliver at scale,” Kelcy Pegler, CEO of FlexGen, said in a news release. “The addition of CES strengthens our service platform and reinforces our leadership in energy storage technology.”

Ahmad Atwan and Constantine Triantafyllides co-founded CES in 2022. As a startup, CES had raised $8 million in venture capital, according to PitchBook.

“CES has achieved a market leadership position in battery storage services by focusing on reliable speed of service delivery and optimizing asset performance,” Atwan, the company’s CEO, added the release. “FlexGen and CES have been strong partners for years, and this transaction enables us to deliver more robust solutions across a complementary set of customers and markets.”

CES will continue to operate its remote operations center in Houston for over 1 gigawatt of solar assets and 4.5 gigawatt-hours of battery assets, while FlexGen will maintain its remote operations center in Durham.

Halliburton Labs names 4 new clean energy startups to incubator

green team

Four new companies have joined Halliburton Labs, the incubator for early-stage energy and climate startups run by Houston energy giant Halliburton.

Halliburton Labs provides the emerging companies with mentorship, industry connections, laboratory access and other resources as they work toward commercialization, according to a news release.

The four new members include:

  • Nandina REM, a Singapore-based company that delivers carbon fiber thermoplastics. It turns end-of-life assets into new, reliable, high-performance materials for the aviation, aerospace and defense industries in a fraction of the time of standard supply chains.
  • Noon Energy, a California-based company that delivers clean, reliable electricity with ultra-long duration energy storage. Its system uses solid oxide electrochemical cells and stores energy as abundant, flexible industrial gases.
  • Proof Energy, a Silicon Valley-based company developed by the Lawrence Berkeley National Laboratory that is commercializing next-generation metallic solid oxide fuel cell (M-SOFC) technology. Its system uses widely available fuels such as ethanol, methanol, ammonia, and natural gas as hydrogen carriers to enable lower-cost, low-emission commercial transportation, and also offers a zero-emission heating solution to preserve battery range in electric vehicles.
  • Tidal Metals, a New Jersey-based company that has developed technology to economically make decarbonized magnesium metal from seawater and electricity.

"Halliburton Labs exemplifies our commitment to advance a secure and pragmatic energy future," Jeff Miller, chairman, president and CEO of Halliburton, said in the news release. "We welcome these companies into our ecosystem, where they will gain access to the tools, expertise, and connections needed to scale their technologies."

Auckland-based Aquafortus Technologies and California-based Sunchem joined Halliburton Labs in September. With the addition of the four new members, the incubator currently supports six early-stage companies.
