Concentrated Solar Power with Storage CSP+ ( TeK-THink ) – This video explores and explains the Gemasolar solar thermal tower power plant near Seville, Spain. Concentrated solar thermal power towers focus the suns rays at a single point of a heat engine located in the tower head using computer controlled mirrors. Advantages of Solar Thermal Tek over that of photo-voltaic include that much higher efficiencies of conversion that are possible with solar thermal and energy storage can occur as heat for later conversion ito electricity.

Concentrated Solar Power (CSP) is a technology which produces electricity by concentrating solar energy in a single focal point.
Consider a parabolic trough system: parabolic troughs are large mirrors, shaped like a giant U.
One big advantage of these parabolic trough systems is that the heat can be stored and used later to keep making electricity when the sun is not shining. Spain has the second?most installed CSP capacity at 182 MW and has much more under development. One major competitive advantage of concentrated solar power systems is that they closely resemble most of the current power plants. Moreover, concentrated solar power production have been shown to create more permanent jobs and stimulate the economy as compared to its natural gas counterparts. A huge environmental benefit that should not be overlooked is that simple and non-polluting concentrated solar power technology can be deployed relatively quickly and can contribute substantially to reducing carbon dioxide emissions. However, the cost of these technologies is still high to enter the global market on a larger scale, and needs to decrease before such an entry can be possible.
Concentrated solar power or CSP systems are used primarily for commercial applications and have been used successfully in the United States and other locations for more than 30 years to power large commercial buildings and much more.
Solar concentrating technologies use lenses or large mirrors and an intricate and customized tracking system to focus sunlight coming from a large area onto a specific smaller area.This light, once focused, is used for heating purposes or directed onto photovoltaic surfaces for providing power.
There is a debate within the environmental and solar energy communites over whether it is useful to create large scale solar energy facilities in remote locations.
Because wider exploitation of renewable energy sources is a key priority for western countries, energy and research companies have made big investments to develop a new type of solar plant based on a concentrating solar power (CSP) system. Sister companies Abengoa Solar and Abener built the PS10 the PS20 solar plants in Sanlucar la Mayor, Seville, Spain. We developed the Heliostat Calibrating System to calibrate 624 heliostats for the PS10 plant and 1.255 heliostats for the PS20 plant.
The system adjusts the heliostat movements automatically in relationship with other heliostats.
In addition, the IP camera is a high-resolution black and white camera used over gigabit Ethernet.
Solar energy is converted through two very different techniques to create electricity,either by using Solar cells (photovoltaic cells), or by concentrating the sun's energy enough to heat a fluid which then produces steam from heating water. Below we see the most popular form of solar collector, parabolic mirrors that focus the sun's energy onto tube in the foreground through which a fluid flows.
The solar dish below enables enough solar energy to be concentrated onto a small area so that temperatures are raised high enough to create syngas(a mixture of hydrogen and carbon monoxide) from methane and carbon dioxide, or methane and water, without the need of catalysts. Imagine how hot it would be if an entire field’s worth of sunlight were focused onto one tiny point.
The beam created by all of these reflecting mirrors is used to heat a liquid to an extremely hot temperature—sometimes over 1000°F! Solar concentrating power is important because it produces energy without releasing harmful greenhouse gases into the atmosphere.
In fact, all of the energy that the ocean, land, and air absorb from the Sun in just 1.5 hours could power the whole Earth for an entire year! Many countries, including the United States, are beginning to adopt concentrating solar power.
Gemasolar was the first Concentrated Solar Thermal Power to include a molten salt storage system to allow the plant to produce energy 24 hours per day.


The Gemasolar project produces 20MW which over the course of a 10 hour sunlight day would be about 72,800 mWhours of energy.To put this in perspective that is enough power for about 25,000 average sized homes.
These heliostats automatically track the sun during the day and maximize the available power to the head with temperatures approaching that of the surface of the sun.
Solar PV produces only electricity which must be stored as electricity or converted to another storable energy carrier. This concentrated energy is used to produce steam, heat up fluids, and activate turbines that produce electricity.
These troughs are connected together in long lines and will attract sun throughout the day.
A major advantage of the concentrated solar power plants is that they generate power best during the late afternoon – during peak demand – and can therefore potentially displace the use of fossil fuel plants that emit the greenhouse gases that cause climate change.
For example, much of the equipment now used for conventional, centralized power plants running on fossil fuels can also be used for concentrated solar power plants. The 4,000 MW deployment scenario was estimated to create about 3,000 permanent jobs from the ongoing operation of the plants. Each concentrated solar power plant provides emissions reductions compared to its natural gas counterpart; the 4,000 MW scenario in this study offsets at least 300 tons per year of NOx emissions, 180 tons of CO emissions per year, and 7,600,000 tons per year of CO2. Today, concentrated solar power technology has a cost somewhere between those of Photovoltaics and wind (1W=4EUR). In Australia we can get good quality solar panels installed from around $2.40 per w, and wind for about the same.
They concentrate the sun to a fine poit which focuses on a line of fluid, heating it to a very high temperature, which creates steam which runs a turbine.
Because, fossil fuels are emitting more pollution for generating electricity and it makes our environment polluted. The installation of a system will disrupt local widlife, however that's pretty much where the impact on the environment stops.This type of power is beneficial because it uses the sun's rays to generate power instead of relying on messy fossil fuels to do the same work.
Yes, it is certainly better than using fossil fuels, but consider some of the other environmental impacts.A large scale CSP plant will inevitably cause significant disruption to the animals, plants and complex ecosystems on the Earth in that area. In these systems, incoming solar radiation is concentrated using a heliostat field in a receiver situated on top of a tower that holds the mirrors.
A Modbus driver is also required for communication with the heliostat mechanic control subsystem. However, an error of milliradians can result in a concentration of power from the tower’s central site for the heliostats located furthest from the site, leading to a reduction in generated power. The sun warms his poorly insulated feet, allowing him to get enough rest to go hunting for food again. These are both relatively easy techniques as Solar cells can now be mass produced which are 15% efficient, and solar concentrators needed to produce electricity only need to reach hundreds of degrees.
Below we show a huge array of mirrors that in are focused on the tower (lower right) in Spain.
The fluid is heated, and in turn heats water to again produce steam, which as above turns a steam generator and generates electricity. A tiny magnifying glass is able to focus just a little bit of the Sun’s light into a hot beam. The mirrors are lined up in a north-south direction and they follow the Sun as it moves from east to west.
These mirrors are all directed at one single point—a tall tower containing the liquid to be heated. Bigger better concentrated solar thermal power towers ( CSP +) are being planned in the Middle East and the US that will have the capacity to produce 110MW  such as the Crescent Dunes plant in Nevada.
When the sun’s heat is reflected off the mirror, the curved shape sends most of that reflected heat onto a receiver.
Large?scale concentrated solar power plans have also been announced in Jordan, South Africa, and the United Arab Emirates.
CSP simply substitutes the use of concentrated solar power instead of combustible fossil fuels to produce electricity. For each 100 MW of generating capacity, concentrated solar power production was estimated to generate 94 permanent jobs compared to 56 jobs and 13 jobs for combined cycle and simple cycle plants, respectively.


Consequently, additional large-scale research efforts are necessary to further advance concentrated solar power technology to make it profitable and compatible as an alternative source of clean energy.
Even though it may be located in a big desert that may seem to serve little purpose, that ecological disturbance does have an impact on the region.The good news is, some CSP companies are working to reduce their environmental impact. The solar concentrator, which captures the sunlight, and the power conversion unit work together to create electricity using mirrors and a central engine.Power Tower Systems - huge flat mirrors are lined up and used to direct the sun's rays to the top of a tower where a receiver containing fluid captures it. These mirrors follow the sun’s orbit using two movement axes to maximize the luminous flux reflected on each mirror. We customized an application based on artificial vision for the capture, analysis, and image treatment of the solar disc projection.
All generated numeric, alphanumeric, and image data is saved in a central database using the LabVIEW Database Connectivity Toolkit.
A wide dynamic range of 120 dB provides the image capture and analysis of the projection of the solar disk for every heliostat. However, if we want to make fuels, concentrating the sun's energy to create a very high temperatures, the order of 1000 C, is required. The concentrated solar energy heats water into steam which turns a steam turbine, which generates electricity. One key to this process is that equal quantities of methane and carbon dioxide are needed as inputs.
Instead of focusing light at a single point, the light is directed along a pipe containing the liquid to be heated. The receiver tube is filled with a fluid; it could be oil, molten salt, something that holds the heat well. Today, the United States is the world leader in installed concentrated solar power capacity, with 429 MW operating in three states.  Approximately 7,000 MW from concentrated solar power is in development and the DOE projects that 2 million homes could be powered by concentrated solar power energy in the United States in 2020.
Moreover, Egypt, Morocco, and Mexico received financial support from the Global Environment Facility of the World Bank to build parabolic trough hybrid systems and are in the implementation stages of the process. This means that concentrated solar power can be integrated fairly easily into today’s electric utility grid. So you don’t calculate the amount of power based on standard solar power calculations as you do with Solar PV roof panels. One company that made news recently is eSolar which is committed to building their plants on previously developed land so that they don't disrupt natural habitats.A big, remote solar power plant will require long transmission lines in order to relay energy to the users of that energy who live in urban or suburban areas. At any time, each heliostat has to correct its elevation and azimuth angles to track the sun movement in the sky.
Basically, this super hot liquid heats water in a heat exchanger, and the water turns this heat. Finally, the Desertec Foundation has a highly ambitious plan and is gathering the support of companies from Germany to potentially build a 100,000 MW CSP project in the Sahara Desert and power lines across the Mediterranean Sea to connect it to Europe. This also makes concentrated solar power technology the most cost-effective solar option for large-scale electricity generation. To supervise the heliostat command, we implemented an encapsulated RS232 protocol and two IP cameras over gigabit Ethernet to guarantee the required bandwidth.
It is automatically instructed to zoom, pan, and tilt, as well as conduct preventive maintenance of the heliostat field.
The steam is sent off to a turbine, and from there it is business as usual inside a power plant.
Many remote locations that can be used for solar plants exists in the middle of a desert where water is scarce. Once the fluid transfers its heat, it is recycled and used over and over, and the steam is also cooled, condensed and recycled again and again.
Some innovative CSP companies such as Bright Source Energy in California are developing new technologies that require less water.Some people argue that these large scale solar plants, besides being environmentally less friendly than residential solar systems, and potentially more costly, also perpetuate the business model of large, corporate owned utilities.
