From what I see, it is a central with cylindro-parabolic mirrors.

and there is also a tower; original mixed system.

These are two different projects on the same site.

These are two different projects on the same site.

Is that to compare?
It would be interesting to know the performance and the differences in manufacturing and maintenance costs (2 motors for each focusing mirror, only one for a ramp of curved mirrors.)

Curved mirrors must be more expensive to manufacture. They can only be oriented in one direction.
The temperature of the heat transfer fluid is different too.

Spain wants to increase its concentrated solar capacity by 5 GW by 2027.

How Spain's Auction Can Achieve the 5 GW of Concentrated Solar Power it Wants

September 17, 2020 evwind

Spain's National Energy and Climate Plan, the PNIEC (Plan Nacional de Industria, Energia y Clima) includes a desired 5 GW of Concentrated Solar Power added to its existing 2.3 GW, with 2.5 GW in a first tranche from 2021 to 2025 and a second 2.5 GW from 2026 to 2027.

Abengoa has completed work on the first 200 MW concentrated solar park out of the three to be built.
Each park has 2120 parabolic collectors of 40 tonnes for 1430 m2!

Abengoa advances in the construction of the world's largest concentrated solar power complex in Dubai

September 24, 2020 dream

The company has just celebrated the completion of the first solar field of the three 200 MW parabolic trough plants which is building in phase IV of the Mohammed bin Rashid Al Maktoum (MBR) Solar Park, in the United Arab Emirates.
Its construction has involved the installation and assembly of 2,120 collectors, each weighing 40 tons.



Abengoa (MCE: ABG / P: SM), the international company that applies innovative technology solutions for sustainability in the infrastructure, energy and water sectors, has just celebrated the completion of the first solar field of the three which is building in the largest solar complex in the world: the Mohammed bin Rashid Al Maktoum Solar Park. Phase IV of MBR Solar Park is currently under development by Noor Energy 1 PSC, a company owned by DEWA (Dubai Electricity and Water Authority), ACWA Power, and Silk Road Fund.

Abengoa provides the technology and is responsible for the design, engineering and construction, for Shanghai Electric Group Co. Ltd., of three parabolic trough plants of 200 MW each, which are part of phase IV of the complex. Now, the Dubai desert has been the scene of the installation of the last of the 2,120 parabolic trough collectors which are part of the solar field of the first of the plants and which has involved the assembly of more than 53,000 tons of structures, even breaking production records, having been installed up to 80 collectors per week.

A new generation of parabolic trough collectors

These collectors, with a 1,430 m2 mirrored surface each in the shape of a parabola, are responsible for concentrating solar radiation, heating a transfer fluid, which will produce steam that feeds a turbine to generate electricity. In addition to this, the collectors installed in this plant are part of the new generation of big aperture parabolic trough collectors, also manufactured by Abengoa, the Spacetube 8.2 ++, which is the parabolic through with biggest aperture in current commercialized applications. Its innovative design resulted in important improvements regarding its optical accuracy, optimization of assembly and a reduction in manufacturing and installation costs.

Chile: inauguration of the largest solar thermal power plant in Latin America

AFP published on June 08, 2021

Chile on Tuesday inaugurated the first solar thermal power plant in Latin America, in the Atacama desert (north), the driest and sunniest in the world, a project that should help the country achieve carbon neutrality in the horizon 2050.

In a circular area of ​​over 700 hectares, 10.600 mirrors surround a tower 250 meters high, the top of which is bombarded by the rays of the sun.

A tank containing molten salts is thus heated to more than 560 degrees to produce steam which drives a turbine generating 110 megawatts of clean electricity.

This infrastructure is combined with an adjacent photovoltaic power plant, and the two together provide a total of 210 megawatts of renewable energy.

This project, called "Cerrado dominador" (the dominant hill), has the particularity of being able to operate 24 hours a day, even in the absence of sun, because the molten salts generate energy for 24 hours.

"This will allow us to save more than 600.000 tonnes of CO2 emissions per year. This is the equivalent of what 300.000 cars emit in one year," Chilean President Sebastian Piñera said at the meeting. inauguration of the project, construction of which began in 2014.

This project of the Spanish companies Abengoa and Acciona was built near the municipality of Maria Elena, about 200 kilometers east of the coastal town of Antofagasta, in the middle of the Atacama desert, at about 3.000 meters above sea level. .

Mr. Piñera said that this was a new step in Chile's commitment to renew its energy matrix by 2050 and to achieve by that date the carbon neutrality provided for in the Paris climate agreement. , that is to say to be a country without net CO2 emissions.

"Chile was a country poor in energies of the past, we had little oil, little coal, little gas, but is immensely rich in energies of the future. We have the deserts with the highest radiation in the world (.. .), the best winds in the world, geothermal energy that comes from volcanoes, tidal energy that comes from the sea, "said the Chilean president.

Chile also wants to become a benchmark in the production of green hydrogen, which is the subject of a broad consensus around the world as a fuel intended to replace polluting fossil fuels.

When for his forum on the CEM12 / MI6 climate, which Chile has virtually hosted, the country has committed alongside the United Kingdom, Australia and the European Union, to promote green hydrogen as a fuel.
