SWiFT Facility Prepared for More-Efficient Operations & Advanced Turbine-Turbine Wake-Interaction-Control Research

The SWiFT facility comprises three heavily instrumented and modified variable-speed, variable-pitch Vestas V27 turbines and two 60 m anemometer towers, with the first two turbines spaced three diameters apart, perpendicular to the prevailing oncoming wind, and the third turbine five diameters downwind (the turbines form a three, five-, six-rotor-diameter-length triangle). Two turbines are funded [...]

Sandians Recognized in Environmental Science & Technology’s Best Paper Competition

A paper by Vince Tidwell, Barbie Moreland, and Katie Zemlick (all currently in or formerly members of Sandia’s Earth Systems Analysis Dept.), “Geographic footprint of electricity use for water services in the western US,” was selected by Environmental Science & Technology (ES&T) as the 2014 first runner-up for best paper in the “Environmental Technology” category. [...]

CRF Researchers Are Source for 2015 QTR Sidebar Content

On September 10th, Energy Secretary Ernest Moniz released the second Quadrennial Technology Review (QTR 2015), which examines the most promising research, development, demonstration, and deployment (RDD&D) opportunities across energy technologies to effectively address the nation’s energy needs. Specifically, this analysis identifies the important technology RDD&D opportunities across energy supply and end-use in working toward a [...]

Sandia Research Aims to Enhance Understanding of Radiometric Instruments

Sandia and Photovoltaic Performance Labs, Inc. have partnered on the PVSENSOR project to measure, characterize, and understand modern radiometric instrument intricacies. Such instruments are used to measure the amount of sunlight impinging on a plane and are primarily used as reference devices for PV systems. Two identical sets of 21 radiometers are mounted on the [...]

Sandia’s Supercritical Carbon-Dioxide/Brayton-Cycle Laboratory Signs Important MOU with Industry Partners

Sandia and eight other companies and research organizations* will collaborate to advance a distributed power system that can produce cleaner, more efficient electricity. The memorandum of understanding (MOU) focuses on developing an energy-conversion system based on supercritical carbon dioxide (sCO2)/Brayton-cycle technology. Gary Rochau, manager of Sandia’s Advanced Nuclear Concepts Dept. said sCO2/Brayton cycle technology could [...]

Sandia’s Algae Nutrient Recycling Project Is a Triple Win

Nitrogen and phosphate nutrients are among the largest costs in cultivating algae for biofuel production. Sandia molecular biologists (in Sandia’s Systems Biology Dept.) and Ryan Davis (in Sandia’s Biomass Science and Conversion Technology Dept.) have shown they can recycle ~⅔ of those critical nutrients, and aim to raise the recycling rate to close to 100%. [...]

Stion Commissions PV System at Sandia Regional Test Center

Stion PV system installed and the Sandia RTC site. Thin-film solar module manufacturer Stion has commissioned a 12 kW fixed latitude ground-mounted photovoltaic (PV) system at the DOE’s New Mexico Regional Test Center (RTC), located at Sandia. The system will be monitored and tested to collect a range of data related to the [...]

Version 24 of the Composite Materials Database Now Available for Download

Montana State University researchers have added acoustic emission and digital image correlation instrumentation to enhance the data collection capabilities of the substructure test fixture. Wind-turbine blade growth continues to have the largest impact on energy capture and levelized cost of energy (LCOE) reduction. While the 40–45 meter blade is today’s mainstream segment, it [...]

Wave-Energy/-Device Modeling: Developing A 1:17 Scaled Model

Many theoretical studies show that additional energy can be captured through control of the power-conversion chains (PCCs) of resonant wave-energy converter (WEC) devices. The numerical models employed in these studies are, however, idealized to varying degrees. The objective of the Resilient Nonlinear Controls (RNLC) project is to validate the extent to which control strategies, given [...]
