Conversion-efficiency mark is a world record for a two-junction solar cell measured under one-sun illumination The Energy Department’s National Renewable Energy Lab has announced a world record of 31.1% conversion efficiency for a two-junction solar cell under one sun of illumination. NREL Scientist Myles Steiner announced the new record June 19 at the 39th IEEE Photovoltaic Specialists Conference in Tampa, Fla. The previous record of 30.8% efficiency was held by Alta Devices. The...

Wood borer makes its own enzyme, which could thrive in industrial setting Researchers from the United Kingdom, the Energy Department´s National Renewable Energy Laboratory (NREL), and the University of Kentucky have recently published a paper describing a novel cellulose-degrading enzyme from a marine wood borer Limnoria quadripunctata, commonly known as the gribble. Gribbles are biologically intriguing because they exhibit a relatively unique ability to produce their own enzymes...

CSP with thermal energy storage boosts California electric grid Researchers from the U.S. Department of Energy´s National Renewable Energy Laboratory (NREL) have quantified the significant value that concentrating solar power (CSP) plants can add to an electric grid. The NREL researchers evaluated the operational impacts of CSP systems with thermal energy storage within the California electric grid managed by the California Independent System Operator (CAISO). NREL used a...

The latest national survey of 100% biodiesel (B100) "blend stock" samples by the U.S. Department of Energy´s National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers — along with reliable operation of the nation´s vehicles powered by biodiesel blends. “The survey showed a...
