Advanced Controls of Wave Energy Converters May Increase Power Capture Up to 330%

Although ocean waves represent an enormous energy resource, most existing WEC designs efficiently produce power only within a narrow wave frequency range. Advanced control of the power-conversion chain can alter this paradigm. Models have shown absorbed-power increases ranging from 100% to 330%. To move from idealized, theoretical paper studies to deployable WEC hard­ware, requires rigorous [...]

Sandia-Electric Power Research Institute Partnership Publishes Photovoltaic Reliability Report

Sandia and the Electric Power Research Institute (EPRI) are jointly engaged in a multiple-year research effort to examine photovoltaic (PV) plant reliability performance obtained through documented field data. Findings and analyses, derived from the PV Reliability Operations Maintenance (PVROM) database, are intended to inform industry best practices around the optimal operations and maintenance (O&M) of [...]

Sandia Releases Open-Source Hydrokinetic Turbine Design Model, CACTUS

In an effort to support marine hydrokinetic (MHK) developers and companies as they advance their technologies, Sandia recently released an open-source version of CACTUS (Code for Axial and Cross-flow TUrbine Simulation) and an accompanying user’s manual authored by Jon Murray and Matt Barone (both in Sandia’s Aerosciences Dept.). Sandia developed CACTUS to design hydrokinetic turbines and [...]

Sandia Combustion Chemist to Be Awarded Polanyi Medal

Sandia’s Craig Taatjes (in Sandia’s Combustion Chemistry Dept.), whose ground­breaking work on Criegee intermediates has provided scientific insight into hydrocarbon combustion and atmospheric chemistry, has been selected to receive the prestigious Polanyi Medal by the International Symposium on Gas Kinetics. “The list of previous recipients of this award includes some of my greatest scientific mentors [...]

Sandia PV Team Publishes Book Chapter

The book, Solar Energy Forecasting and Resource Assessment, provides an authoritative voice on the accuracy of long-term resource projections and addresses grid operators’ concerns about variable short-term power generation, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications [...]
