Concentrator photovoltaics may play significant role in growth of solar electricity because of scalability. Need to take a bird?s eye view for the design and a worm?s eye view for diagnosis.

Solar is growing rapidly, and the concentrating photovoltaics industry-both high- and low-concentration cell approaches-may be ready to ramp production in 2009.

The presentation describes Concentrating Photovoltaic power (CPV), why it is important, the associated the opportunities and challenges, and more than 5-dozen companies that are pursuing the approach.

In the United States, concentrating solar power (CSP) is one of the most promising renewable energy (RE) technologies for reduction of electric sector greenhouse gas (GHG) emissions and for rapid capacity expansion. It is also one of the most price-competitive RE technologies, thanks in large measure to decades of field experience and consistent improvements in design. One of the key design features that makes CSP more attractive than many other RE technologies, like solar photovoltaics and wind, is the potential for including relatively low-cost and efficient thermal energy storage (TES), which can smooth the daily fluctuation of electricity production and extend its duration into the evening peak hours or longer. Because operational environmental burdens are typically small for RE technologies, life cycle assessment (LCA) is recognized as the most appropriate analytical approach for determining their environmental impacts of these technologies, including CSP. An LCA accounts for impacts from all stages in the development, operation, and decommissioning of a CSP plant, including such upstream stages as the extraction of raw materials used in system components, manufacturing of those components, and construction of the plant. The National Renewable Energy Laboratory (NREL) is undertaking an LCA of modern CSP plants, starting with those …

The US has a national set of codes and standards that address the use of hydrogen technologies. These documents are published by several organizations and are not all directly adopted by government authorities. The US Department of Energy (DOE) has acted as the central organizing group to identify these documents and present them as a coherent and integrated set of requirements.

Battery cost, calendar life, and cycle life are three important challenges for those commercializing plug-in hybrid electric vehicles; battery life is sensitive to temperature and solar loading.

PV industry can benefit from reliability testing experience of microelectronics industry . Si modules perform well in field; CdTe/CIGS must be sealed to moisture; CPV in product development stage.

Describes results of a sample survey of the quality of B20, a biodiesel blend, collected from U.S. public pumps and fleets as part of a joint effort by NREL, the NBB, and engine manufacturers.

The data analysis objectives are: (1) Independent assessment of technology, focused on fuel cell system and hydrogen infrastructure:performance, operation, and safety; (2) Leverage data processing and analysis capabilities from the fuel cell vehicle Learning Demonstration project and DoD Forklift Demo; (3) Establish a baseline of real-world fuel cell operation and maintenance data and identify technical/market barriers; (4) Support market growth of fuel cell technologies by reporting on technology features relevant to the business case; and (5) Report on technology to fuel cell and hydrogen communities and stakeholders.
