Kestrel Supercomputer Energizes Energy Research
Kestrel entered the TOP500 list in 2023 as the 67th most powerful supercomputer in the world for its CPU capacity. This year, Kestrel's GPU capacity achieved #71 in world. With installation now complete, computing for energy research is elevated to new heights enabling emerging AI and machine learning workflows.

Situated Visualization of Photovoltaic Module Performance
The Insight Center's new situated visualization capability overlays digital information onto physical objects or environments, enabling users to explore spatially mapped data in the physical world. For example, users can adjust the orientation of a physical photovoltaic module and visualize real-time performance changes on the module itself.

Tool Highlights Hydrogen Cost-Reduction Strategies for Large-Scale Industrial Use
New tools, like the Hybrid Environment Resources and Operations (HERO) tool, lower the barriers for researchers to use computational capabilities and develop their workflows faster. In FY 2024, HERO helped visualize performance data from more than 50,000 hybrid U.S. energy plant locations for cost reduction and storage strategies.

Early Careers in Computing
Understanding Fuel Cell Device Complexity With Artificial Intelligence
In collaboration with NREL researchers, graduate students from Rensselaer Polytechnic Institute and New Mexico State University used Kestrel to complete their dissertation work using AI to understand transport and reactivity in fuel cell devices. The goal is to quickly develop AI models of electrocatalytic devices for any underlying chemistry, catalyst, and polymer electrolyte.
