Transcript of C.S.P. Solar Energy

C.S.P. Solar Energy Summary Pros Cons Industry Leaders Current Projects Sources http://www1.eere.energy.gov/solar/csp.html
Washington Post

C.S.P. - Concentrating Solar Power Parabolic Trough Systems type of Linear Concentrator System

most commonly used CSP system in the U.S.
Three main systems:
Linear Concentrator System, Dish/Engine System, and
Power Tower System use mirrors to reflect and concentrate sunlight onto receivers that collect the solar energy and convert it to heat

focuses a large amount of sunlight onto a small area

the heat energy is converted into electric energy Types of CSP Energy

concentrated solar thermal (CST)
concentrated photovoltaics (CPV)
Concentrating Photovoltaics and Thermal (CPT) “Solar power project in Mojave Desert gets $1.4 billion boost from stimulus funds” Project developer is BrightSource Energy
$1.4 billion loan guarantee for a solar thermal power complex

Reduce megawatts of electricity from 440 to 392

Power 140,000 California homes
Complex will create about 1000 jobs

Require 3 solar fields to place thousands of heliostats that will capture more solar energy than other solar thermal devices Abengoa Solar

Solar Millenium


BrightSource Energy Abengoa Solar Building the world’s largest solar plant in Gila Bend, Arizona: Solana

First Concentrated Solar Power plant that produces electrical energy in U.S. Will eliminate 400,000 tons of CO2 and supply clean power to 70,000 homes

Abengoa also has projects in California, Texas, and Colorado as well as international projects and projects in Spain power block trough eSolar Sierra Sun Tower

5 MW of energy, power for 4,000 homes

Reduce CO2 emission by 7,000 tons/year Protection from unpredictability of other energy prices
Long term financial benefits

Low maintenance costs
A renewable resource separate from the declining supply of fossil fuels
Will eventually offer solar to smaller as well as larger scale projects with use of an energy grid, making solar power an option for all

Option to sell back excess power
Reduces environmental impact and carbon footprint Cheaper than nuclear power option Short term financial problems

High installation fees
-starting rate is 27 cents per kWh (about three times the price of usual power)
-materials and facilities used in panel production
Only available for mid-large size projects for 25-500 kW projects

Current goal is only to provide for 1500 houses at a time

Twelve cents is currently added onto all San Antonio residences’ power bills to pay for this project
Availability of source, like on cloudy days
-decrease in problem due to grid system and improved technology
