News Summary
The University of Pennsylvania’s student team CarboWells has captured the top prize in the Y-Prize Competition with their revolutionary 3D-printed concrete well plug. This plug is designed to capture carbon and improve the integrity of abandoned oil and gas wells, addressing critical environmental concerns posed by these dormant sites. CarboWells received a $15,000 award to advance their sustainable technology that leverages diatomaceous earth, enhancing well sealing and reducing greenhouse gas emissions.
Philadelphia – CarboWells, a student team from the University of Pennsylvania, has been awarded the top prize in the 2026 Y-Prize Competition for their innovative 3D-printed concrete well plug designed to capture carbon and enhance the integrity of abandoned oil and gas wells. The team received a $15,000 grand award to further develop and commercialize their groundbreaking solution for a critical environmental challenge.
The winning technology directly addresses the pressing issue of approximately 2 million abandoned oil and gas wells across the United States, including an estimated 350,000 in Pennsylvania alone. These dormant wells pose significant environmental risks, including the leakage of methane and other harmful gases, contamination of groundwater, and a contribution to climate change. Traditional concrete plugs used to seal these wells often degrade and crack over time, leading to costly repairs and continued environmental damage.
Innovative Carbon-Capturing Solution
CarboWells’ patented well plug offers a robust and sustainable alternative. The core of their innovation lies in its composition and design: it is a 3D-printed concrete plug that incorporates diatomaceous earth, a natural material known for its carbon dioxide absorption capabilities. As CO2 reacts within the concrete, it actively strengthens the plug over time, improving its long-term stability and effectiveness. Furthermore, the plug features an internal structure inspired by patterns found in nature, engineered to optimally distribute pressure and prevent the formation of cracks, ensuring a more secure and lasting seal for aging wells.
The team behind CarboWells is composed of students from diverse academic backgrounds at Penn, including Yash Iyer, Ronith Lahoti, Bhuranyu Mahajan, Yuki Qian, and Ali Altan Yilmaz. Their interdisciplinary expertise contributed to the comprehensive development of both the technology and its compelling business plan.
About the Y-Prize Competition
The Y-Prize is an annual innovation competition hosted by the University of Pennsylvania, challenging students to conceive and develop powerful real-world applications for emerging technologies invented by Penn researchers. Now in its second decade, the competition fosters entrepreneurial thinking, collaboration, and commercial strategy among students from across the university.
The competition is a joint initiative, sponsored by the William and Phyllis Mack Institute for Innovation Management, Penn Engineering, Venture Lab, and the Penn Center for Innovation. It was founded in early 2012 by Professor Vijay Kumar, now dean of Penn Engineering, alongside Professor Mark Yim and Dr. David Hsu.
Recognizing Other Innovators
In addition to CarboWells, this year’s Y-Prize competition featured several other promising finalists who presented innovative applications for advanced concrete technologies. The other finalists included Aeronyx, Haven, and Lattica. Aeronyx proposed 3D-printed TPMS concrete modules designed to replace plastic packing in industrial scrubbers, integrating carbon capture to boost longevity and lower maintenance costs. HAVEN showcased a concept for customizable concrete wave-energy dissipators aimed at protecting shorelines while also fostering ecological growth.
The Y-Prize continues to be a vital platform for transforming cutting-edge academic research into tangible solutions that address significant global challenges, demonstrating the entrepreneurial spirit and innovative potential within the University of Pennsylvania community.
