charlie gay:it's important for sunshot to focus on storage because that's the long term lever that wehave available to expanding adoption of solar. concentrating solar essentially uses fieldsof mirrors and focuses the light onto one spot... heating up a fluid that can then runa turbine. that fluid can then be stored and dispatchedwhen the electricity is needed.
Efficiency Of Solar Panels, sandia's work with the falling particle receiverwill lead to lower costs because now we have another pathway by which we can get to highertemperatures. higher temperatures mean higher efficiency. higher efficiency means lower cost.
cliff ho:the value of concentrating solar power is that it generates heat first and foremost. and that heat can be very cheaply and efficientlystored for use later on to produce electricity. with conventional csp technologies using moltensalt, we can provide 24/7 electricity production. right now the big barrier is cost. to get to even higher efficiencies, we havedeveloped new heat transfer and storage media. these are ceramic particles, used in oil andgas for hydraulic fracturing. and so when you drop them through a beam ofconcentrated sunlight, the heat very efficiently. we've tested this at our prototype fallingparticle receiver at sandia.
we've gotten to peak temperatures over 900degrees celsius. so these particles enable the higher temperatures,which can reduce costs of direct storage as well as enable the higher efficiency powercycles. being able to see the opportunity and thepotential for these higher temperature csp systems has been really exciting. charlie gay:the work that we fund is high-risk research. helping experimentally test whether thoseideas really work, helps create the foundation-the building block-for industry to scale technology.
