Study Pinpoints Sources of Polluting Vehicle Emissions (Fact Sheet)
Unburned lubricant produces 60%-90% of organic carbon emissions. While diesel fuel is often viewed as the most polluting of conventional petroleum-based fuels, emissions from gasoline engines can more significantly degrade air quality. Gasoline exhaust is at least as toxic on a per-unit-mass basis as diesel exhaust, and contributes up to 10 times more particulate matter (PM) to the emission inventory. Because emissions from both fuels can gravely impact health and the environment, researchers at the National Renewable Energy Laboratory (NREL) launched a study to understand how these pollutants relate to fuels, lubricants, and engine operating conditions. NREL's Collaborative Lubricating Oil Study on Emissions (CLOSE) project tested a variety of vehicles over different drive cycles at moderate (72 F) and cold (20 F) temperatures. Testing included: (1) Normal and high-emitting light-, medium-, and heavy-duty vehicles; (2) Gasoline, diesel, and compressed natural gas (CNG)-powered vehicles; (3) New and aged lubricants representative of those currently on the market; and (4) Gasoline containing no ethanol, E10, Texas-mandated low-emission diesel fuel, biodiesel, and CNG. The study confirmed that normally functioning emission control systems for gasoline light-duty vehicles are very effective at controlling organic carbon (OC) emissions. Diesel vehicles without aftertreatment emission control systems exhibited OC …

SunShot Vision Study: February 2012 (Book)
The objective of the SunShot Vision Study is to provide an in-depth assessment of the potential for solar technologies to meet a significant share of electricity demand in the United States during the next several decades. Specifically, it explores a future in which the price of solar technologies declines by about 75% between 2010 and 2020 - in line with the U.S. Department of Energy (DOE) SunShot Initiative's targets.

Sustainable Energy Resources for Consumers (SERC) Vermont Highlight (Fact Sheet)
Case study on Vermont's innovative strategy for helping low-income families save energy through its Sustainable Energy Resources for Consumers (SERC) program. The DOE Weatherization Assistance Program (WAP) granted Vermont to give its weatherization clients access to solar energy systems and one-on-one assistance from energy efficiency coaches to help clients achieve meaningful and long-lasting reductions in their energy bills. Vermont-SERC is administered by the Vermont Office of Economic Opportunity and is carried out by five local weatherization agencies. The purpose of the program is to identify technologies and new approaches-in this case, solar energy and energy efficiency coaches-that can improve weatherization services to low-income clients. The program selects households that have previously received weatherization services. This has several advantages. First, the clients already understand how weatherization works and are willing to strive for additional energy savings. Second, the weatherization agencies are working with clients who have previously had weatherization and therefore have complete energy usage data from utility bills collected during the first energy upgrade installation. This allows the agencies to select the best potential candidates for solar energy. Agencies have existing knowledge of the homes and can pre-screen them for potential structural problems or lack of south-facing exposure.

Tagged Neutron Source for API Inspection Systems with Greatly Enhanced Spatial Resolution
We recently developed induced fission and transmission imaging methods with time- and directionally-tagged neutrons offer new capabilities for characterization of fissile material configurations and enhanced detection of special nuclear materials (SNM). An Advanced Associated Particle Imaging (API) generator with higher angular resolution and neutron yield than existing systems is needed to fully exploit these methods.

Tappable Pine Trees: Commercial Production of Terpene Biofuels in Pine
PETRO Project: The University of Florida is working to increase the amount of turpentine in harvested pine from 4% to 20% of its dry weight. While enhanced feedstocks for biofuels have generally focused on fuel production from leafy plants and grasses, the University of Florida is experimenting with enhancing fuel production in a species of pine that is currently used in the paper pulping industry. Pine trees naturally produce around 3-5% terpene content in the wood—terpenes are the energy-dense fuel molecules that are the predominant components of turpentine. The team aims to increase the terpene storage potential and production capacity while improving the terpene composition to a point at which the trees could be tapped while alive, like sugar maples. Growth and production from these trees will take years, but this pioneering technology could have significant impact in making available an economical and domestic source of aviation and diesel biofuels.
