Concrete dam with water spilling down one section into a calm river below, surrounded by trees

Researchers at Oak Ridge and Pacific Northwest national laboratories have partnered with Smith-Root Inc. to commercialize “eDNA-bot,” a patented, autonomous aquatic robot that collects and analyzes environmental DNA in real time using artificial intelligence. Developers say the technology could enable continuous, lower-cost biological monitoring for hydropower licensing, invasive species detection and wastewater pathogen monitoring.

Dark underground coal mine tunnel with metal support beams lining the curved walls, muddy ground, and narrow rail tracks running through the center under a single bright overhead light.

Researchers at ORNL used computer models to study whether abandoned coal mines could be turned into underground systems that store energy by pumping water.

Researcher Sean Turner poses at Melton Hill Dam on the Clinch River

Sean Turner, a senior engineer at ORNL, uses large-sample deep learning and hydrology models to predict river temperatures nationwide and assess their impacts on interconnected hydropower and nuclear operations, despite limited observational data. His work focuses on integrating river and power grid models to improve energy reliability, inform infrastructure siting and support water–energy decision-making.
