Page • Sandia partners to anticipate—and resolve—emerging Arctic national security challenges. Security in the Arctic impacts the world stage. A secure Arctic requires the logistics, information, and physical resources needed to prevent or respond to a security event. Security in the Arctic spans operations and infrastructure. Whether the threat comes from sea...

Page • The concept for the ARCUS vertical-axis wind turbine (VAWT) was developed in response to the ARPA-e ATLANTIS program call in 2019. This concept was designed to address the unique challenges for floating offshore wind energy in the U.S. where costs are 3-5 times higher than for land-based wind energy installations....

Page • Vision: Revolutionize the electric power grid through innovative AI/ML research to provide unprecedented efficiency, resilience, and sustainability The increased prevalence of sensors in the grid, ranging from phasor measurement units (PMUs) to advanced metering infrastructure (AMI) in distribution networks, has resulted in an explosion of grid data. Machine learning techniques...

Page • Coupon testing is used to characterize new composite materials to obtain design properties. Wind turbine blades are subjected to a higher number of complex loading cycles not experienced in other applications of composite structures. These loads can lead to structural failure through various mechanisms such as a crack initiated at...

Page • Improving wind-turbine blade manufacturing quality and determining the most cost-effective methods to mitigate environmental damage. Unplanned maintenance and component failures are a concern to both wind plant owners and wind turbine manufacturers. Sandia leads efforts in wind-turbine reliability research, specifically focusing on: Wind plant reliability & analysis Nondestructive inspection Composite...

Page • Reliability, Operations & Maintenance, and Standards Wind-turbine blades are among the largest composite structures made in the world. The economics of energy production dictates that low-cost manufacturing methods be employed to produce cost-effective machines. This, combined with an often harsh operating environment, creates a challenge for blade designers and manufacturers,...
