ESTAP Webinar: Briefing on Sandia’s Maui Energy Storage Study

On March 6, 2013, in EC, Energy, News, Photovoltaic, Renewable Energy, Solar

March 6, 2013 14:00 — 15:00 Eastern The Energy Storage Technology Advancement Partnership project of the Clean Energy States Alliance (CESA) and the Department of Energy is presenting a webinar featuring a case study conducted by Sandia National Laboratory on the Island of Maui and its goals of increasing its renewable energy capacity and the [...]

Sandia Report Offers Reliable Way to Evaluate Unintentional Islanding Risk

A recently released Sandia National Laboratories report, “Suggested Guidelines for Assessment of DG Unintentional Islanding Risk,” outlines a procedure to help utility distribution engineers determine the risk of unintentional islanding in distributed energy generation installations. By providing a quick and reliable way to identify situations in which such risk is negligible, Sandia’s approach can help [...]

Engineering Alternative Fuel with Cyanobacteria

Sandia Truman Fellow Anne Ruffing (8622) has engineered two strains of cyanobacteria to produce free fatty acids (FFAs), a precursor to liquid fuels, but she also found that the process cuts the bacteria’s production potential. She published her work on one strain, “Physiological effects of free fatty acid production in genetically engineered Synechococcus elongatus PCC [...]

Measurements of Thermal Stratification in a Homogenous Charge Compression Ignition Engine

Homogenous charge compression ignition (HCCI) engines use fuel mixed with a substantial amount of excess air or recirculated exhaust gas that is compressed in the combustion chamber until it autoignites. The resulting combustion is a flameless and low-temperature burn that consumes less fuel than traditional spark-ignition internal combustion engines, and therefore, produces less carbon dioxide. [...]

Improved Method to Measure Glare and Reflected Solar Irradiance

Sandia has developed a significantly cheaper, more efficient, and more accurate method of measuring the irradiance from solar reflections using a digital camera. Measurements of reflected solar irradiance is of great importance to industry, military, and government agencies to assess potential impacts of glint and glare from growing numbers of solar power installations around the [...]
