The Integration of Variable Generation Task Force (IVGTF) Task 1–3 report, “Interconnection Requirements for Variable Generation” was posted to NERC’s website in mid-October. Many of NERC’s existing interconnection standards and procedures have been based on technical characteristics and physical capabilities of traditional power generation resources that employ synchronous generators. With the global trend toward renewable energy, the penetration of wind and solar generation is rapidly increasing in many power grids under NERC’s jurisdiction. The IVGTF [...]

Simulations Reveal Ion Dynamics in Polymer Electrolyte

November 13th, 2012|Categories: Energy Storage, News, News & Events|Tags: , , , , , , , |

Improving battery electrolytes is highly desirable, particularly to increase safety and reduce cost. One class of possible new electrolyte materials is ionomers—polymers with a small number of charged groups covalently bound to the polymer backbone. A hindrance to high conductivity in ionomer melts is nanoscale ionic clusters that usually form because of the polymer’s low dielectric constant. Understanding these clusters and their effects on material properties is important for improved design. Recent molecular-dynamics simulations have [...]

The U.S. Coast Guard icebreaker Healy. It’s that time of year again, when we check in to see where the annual Arctic sea ice minimum will end up. We haven’t quite bottomed out at the end of the melt season, yet, but already 2012 has set new records for smallest Arctic sea ice extent and volume, smashing through the numbers from 2007. Records are often attention-grabbing and "exciting," in a way, but while Usain Bolt’s incredible shrinking [...]

Sandia Labs Helping Industry Tackle Wind Turbine Reliability

October 15th, 2012|Categories: Energy, News, News & Events, Renewable Energy, Wind Energy|Tags: , , , , , , , , , |

A new measurement developed by Sandia National Laboratories should help the wind energy industry benchmark its performance, understand vulnerabilities, and enhance productivity. Until now, wind farm owners and operators had no way to compare their output with the output of similar operations. To benchmark the reliability of the U.S. wind turbine fleet and identify major causes of failures and downtime, the U.S. Department of Energy (DOE) directed Sandia in 2010 to build the Continuous Reliability Enhancement for [...]
