Pratt Whitney Rocketdyne Testing

On November 24, 2012 the National Solar Thermal Test Facility (NSTTF) began testing of the Pratt Whitney Rocketdyne (PWR) solar receiver shroud.  Fifteen days of solar testing are scheduled for this testing.  The flux levels on the shroud range between 100 and 500 suns.  The work is sponsored by PWR in cooperation with the Department [...]

Power Towers for Utilities

Desirable Features of Power Towers for Utilities Because of their practical energy storage, solar power towers have two features that are particularly desirable for utilities: flexible capacity factors and a high degree of dispatchability. Power towers can be designed with annual capacity factors up to 60 percent, and as high as 80 percent in summer [...]

CSP Software & Tools

DELSOL DELSOL is a performance and design code that includes optical and economic analyses. An analytical Hermite polynomial expansion/convolution-of-moments method is used to predict flux images from the heliostats in a computationally efficient manner (typically much faster than either MIRVAL or HELIOS). The code accounts for variations in insolation, cosine forshortening, shadowing and blocking, and [...]
