Reduce CO2 Emissions in Electricity Generation

Oper­a­tion Di­a­gram - PS10 Solar Power Plant: He­liostats con­cen­trate sun­light to the tower re­ceiv­er (a forced cir­cu­la­tion ra­di­ant boil­er) to heat water and pro­duce steam at 40 bar - 250 deg.C. The steam drives the tur­bine gen­er­a­tor to pro­duce elec­tric­i­ty. Part of the steam can be stored in tanks, of­fer­ing a back­up to main­tain out­put in cloudy con­di­tions.  More »« Less

Parabol­ic Trough of the Mo­jave Solar Pro­ject: A Solar Ther­mal Col­lec­tor for elec­tri­cal power gen­er­a­tion. Lo­cat­ed at Lock­hart near Harp­er Lake, Cal­i­for­nia.  More »« Less

Solar Parabol­ic Trough Re­ceiv­er with Glass En­ve­lope - Di­a­gram: The heat col­lec­tion el­e­ment (the re­ceiv­er) in­cludes an evac­u­a­tion noz­zle, and glass to metal seals to pre­serve the vac­u­um be­tween the glass en­ve­lope and the metal tube. Chem­i­cal sponges in­di­cate the sta­tus of the vac­u­um.  More »« Less

In­stal­la­tion of Re­ceiv­er - Solar En­er­gy Gen­er­at­ing Sys­tems: New SOLEL re­ceivers (heat col­lec­tion tubes) at SEGS Kramer Junc­tion Con­cen­trat­ing Solar Power sta­tion, 1995.  More »« Less

Clean­ing of Solar Col­lec­tors with Water Truck - Solar En­er­gy Gen­er­at­ing Sys­tems: Parabol­ic trough mir­ror clean­ing at SEGS Kramer Junc­tion solar plant using the del­uge method.  More »« Less

Ae­ri­al View of Kramer Junc­tion's 5 Solar Power Plants - SEGS: The 5 plants have a total gen­er­at­ing ca­pac­i­ty of 150 MW, which can power about 150,000 homes. These plants are part of SEGS' total of 9 plants.  More »« Less

High Alti­tude View of Kramer Junc­tion's 5 Solar Power Plants - SEGS: Coun­ter­clock­wise from lower right: SEGS 3, 4, 5, 6, and 7. Each plant has a 30 MW gen­er­at­ing ca­pac­i­ty.  More »« Less

Field of Parabol­ic Trough Col­lec­tors Dur­ing In­stal­la­tion at Solana Plant: The mir­rored col­lec­tors are built on site, cov­er­ing 3 square miles at Aben­goa's Solana plant.  More »« Less

Mr. Twis­ter Mir­ror Wash­ing Ma­chine - SEGS Plant: A way of clean­ing par­a­bol­ic trough mir­rors at SEGS solar power plant, Kramer Junc­tion. The ma­chine has sprayers that spin as it pass­es by the mir­rors. The fre­quen­cy of wash­ing may vary from week­ly in the sum­mer to every few months in the win­ter.  More »« Less

Water Steam Tanks - PS10 Solar Power Plant: For cloudy tran­sient con­di­tions, the plant has a sat­u­rat­ed water ther­mal stor­age sys­tem with a ther­mal ca­pac­i­ty of 20 MWh, equiv­a­lent to an ef­fec­tive op­er­a­tional ca­pac­i­ty of 50 min­utes at 50% tur­bine work­load. Four tanks are se­quen­tial­ly op­er­at­ed ac­cord­ing to each tank's charge.  More »« Less
