Kestrel Landing Soon

In summer 2023, NREL will install its third-generation HPC system—Kestrel—to enable emerging workflows for rapidly advancing artificial intelligence (AI) applications, driving complementary physics and data-driven approaches by fusing simulation with new sensor data sources.

New Visualization Capabilities Drive Discovery, Decision-Making, and Reasoning

NREL's Insight Center now features a multi-surface, multi-user space along with a 100-megapixel display for 2D interaction with data, and updates to our 3D immersive room more than doubled the resolution for enabling multiple users to explore virtual reality simultaneously from their own perspectives.

Building Trust in Artificial Intelligence To Ensure Equitable Solutions

To help deliver clean energy solutions to communities across the country and around the world, NREL's computational scientists are addressing potential bias in AI early in the research process, and incorporating equity into practices across research, development, demonstration, and deployment.

Research Highlights

NREL's advanced computing research collaborations resulted in more than 300 completed projects, spanning across multiple disciplines and technologies as these featured highlights show. For more details, download the full report.
