No one should feel they are being taken advantage of while pursuing clean energy. At the federal level, you can contact the Federal Trade Commission to report fraud, scams, and bad business practices. You can contact one of the consumer protection offices within your state or territory to see how they can help, too.
While solar PV experienced huge growth in recent years due to falling prices, Solar CSP growth has been slow due to technical difficulties and high prices. In 2017, CSP represented less than 2% of worldwide installed capacity of solar electricity plants. However, CSP can more easily store energy during the night, making it more competitive with dispatchable generators and baseload plants. However, the Moroccan plant is due to lose its rank toNoor Energy 1, Dubai’s 700MW CSP project, which is currently under construction. Morocco currently has the largest CSP project in the world - the Ouarzazate Solar Power Station, which has a capacity of 510MW.
What is concentrated solar power (CSP)?
Although seawater may be seen as a possible solution, this could present solar radiation issues for the surrounding landscape. Similarly, CSP plants can attract animals with its light, and the heat can be fatal for some species. In addition to this, solar thermal power plants have a long service life of up to 40 years.
There are four different types of plants used around the world to create electricity- parabolic dishes, solar power towers, parabolic troughs, and linear fresnel systems. All of these types of plants have nuanced differences, for example, in the type of receiver or heating fluid it employs, but all concentrated solar power plants use mirrors to concentrate the sun’s thermal energy to a receiver. In a CSP plant that includes storage, the solar energy is first used to heat the molten salt or synthetic oil which is stored providing thermal/heat energy at high temperature in insulated tanks. Later the hot molten salt is used in a steam generator to produce steam to generate electricity by steam turbo generator as per requirement. Thus solar energy which is available in daylight only is used to generate electricity round the clock on demand as a load following power plant or solar peaker plant.
Central Power Tower
CSP systems tend to be large, utility-scale projects, capable of providing a lot of electricity as a power source to the grid. For solar technologies, energy storage is critical since the Sun isn't always available for energy production. Most often, oil or molten salt is used to store the heat generated by the concentrated solar energy. This is very cost effective compared to using batteries for storing solar electricity. The largest of these is the Ivanpah Solar Electric Generating System in California’s Mojave desert, with a capacity of 392MW.
Federal support projects from the demonstration batch ran out at the end of 2021. A dish Stirling or dish engine system consists of a stand-alone parabolic reflector that concentrates light onto a receiver positioned at the reflector's focal point. The working fluid in the receiver is heated to 250–700 °C (482–1,292 °F) and then used by a Stirling engine to generate power. Parabolic-dish systems provide high solar-to-electric efficiency (between 31% and 32%), and their modular nature provides scalability. The Stirling Energy Systems , United Sun Systems and Science Applications International Corporation dishes at UNLV, and Australian National University's Big Dish in Canberra, Australia are representative of this technology. A world record for solar to electric efficiency was set at 31.25% by SES dishes at the National Solar Thermal Test Facility in New Mexico on 31 January 2008, a cold, bright day.
Solar thermal enhanced oil recovery
The country plans todouble its CSP capacityby 2025, to 4.8GW as part of a ten-year energy plan. To provide some context,hydropower systemscan achieve up to 90% efficiency and wind turbines can achieve efficiencies of up to 59%. Solar PV efficiencies are similar to concentrated solar power systems with most photovoltaic panels achieving an efficiency of between 14 and 23%. The focused energy is utilized to heat the transfer fluid to above 1000°F in order to create steam and run the central power generator. These projects can also implement the energy storage function cheaply and effectively, providing 24-hour power generation. The two major parts of the system are the solar concentrator and the power conversion unit.
Different types of concentrators produce different peak temperatures and correspondingly varying thermodynamic efficiencies, due to differences in the way that they track the sun and focus light. New innovations in CSP technology are leading systems to become more and more cost-effective. These systems have trackers that follow the direction of the sun along two axes to maximize efficiency.

The solar power tower name comes from the fact that the concentrated solar power is focused not at the focal point of each heliostat dish but at the top of a very tall vertical tower. Here are some of the disadvantages of concentrated solar power systems.CSP is very expensive to set up and run. This is because it requires special materials like molten salt, which is difficult to obtain and costly to source. The concentrated solar energy boils the water producing high-pressure steam that spins a steam generator turbine to produce electricity.

Some new models of Fresnel Reflectors with Ray Tracing capabilities have begun to be tested and have initially proved to yield higher output than the standard version. A legend has it that Archimedes used a "burning glass" to concentrate sunlight on the invading Roman fleet and repel them from Syracuse. The ship caught fire after a few minutes; however, historians continue to doubt the Archimedes story. Concentrated solar power comes with a variety of environmental benefits. The idea is to focus and direct a large area of sunlight into a single point or receiver.
The Solar Two in Daggett, California and the CESA-1 in Plataforma Solar de Almeria Almeria, Spain, are the most representative demonstration plants. The Planta Solar 10 in Sanlucar la Mayor, Spain, is the first commercial utility-scale solar power tower in the world. The 377 MW Ivanpah Solar Power Facility, located in the Mojave Desert, is the largest CSP facility in the world, and uses three power towers. Ivanpah generated only 0.652 TWh (63%) of its energy from solar means, and the other 0.388 TWh (37%) was generated by burning natural gas.
Researchers are investigating solar thermal reactors for the production of solar fuels, making solar a fully transportable form of energy in the future. These researchers use the solar heat of CSP as a catalyst for thermochemistry to break apart molecules of H2O, to create hydrogen from solar energy with no carbon emissions. By splitting both H2O and CO2, other much-used hydrocarbons – for example, the jet fuel used to fly commercial airplanes – could also be created with solar energy rather than from fossil fuels. Of late China has been aggressive in developing CSP technology to compete with other electricity generation methods based on renewable and non-renewable energy sources. In the current 14th Five-Year Plan CSP projects are developed in several provinces along side large GW sized solar PV and wind projects. CSP is often compared to photovoltaic solar since they both use solar energy.
