And they can store the heat under the earth of the day for the night, weeks with sun for those with clouds, to give electricity 24h on 24h this 365 days a year !!!
In hotter than www.dlsc.ca who heats of summer for the winter !!!!!

I repeat, because we did not understand it, because we dig shale gas wells, but not to store heat in perpetuity !!

Europe injects 345 ME into the Ouarzazate solar complex

23 Nov 2012 Enerzine

With a contribution of 345 million euros *, the first solar project in North Africa will benefit from significant support from Europe, representing more than half of the total cost of the project.

A financial commitment of 300 million euros was signed last Tuesday in Marrakech, Morocco, by several organizations including the European Investment Bank (EIB), the French Development Agency (AFD), the KfW Entwicklungsbank (KfW) and MASEN, the promoter of the Ouarzazate solar complex.

The implementation of this loan envelope was facilitated by the granting of a non-repayable aid of 30 million euros from the European Union in December 2011.

European financial support relates to the first phase of the Ouarzazate solar complex, which consists of the construction of a concentrated solar power plant (CSC) and cylindrical-parabolic collectors with a gross installed capacity of between 125 and 160 MW, for an energy storage capacity of at least three hours. It will be the first project of the Moroccan Solar Plan and the largest to date of the Mediterranean Solar Plan, which aims to install 20 GW of additional capacity for the production of energy from renewable sources by 2020.

Hi we're still waiting your tW / h cost estimate... [see that of FULL NEED]

As well as the investment it would represent by country: for power plants of this type - compared to the cost of nuclear tW / h calculated correctly (therefore not at the ridiculous rate currently practiced) - it would be very useful to have your opinion Image

(If Moinsewatt where one of you confirms ...) besides the oil bill will not stop growing ...

The solar thermal - with which it is not counted the other renewable - seems thus quite viable! I have good?

Thus, if we wanted to, with a "Marshall Plan" of energy, we could do without oil.

Yes indeed, we should engage in a big "war" for clean energy.

Desertec is estimated at 1000 G €, but just the hydrocarbon imports in France are 60 G € / year : well, a little less than 17 years only in France cushion the investment for the world.

In the same vein, 1000 G € or G $ are created ex nihilo by the central banks several times a year, to finance dark debts

Le annual US military budget is 700 G $ and even more in times of war.

The crisis of subprimes of 2008 had burned about 500 G €

The "aid" (including loans that will never be repaid) granted to Greece since its bankruptcy: around 500 G € too ...

to summarize, the transition EnR is not done, it is neither because of a financial impossibility, nor because of techniques not mastered ...
Could you explain something to us STP [Lessdewatt]: you who are called in electricity, in order to better understand?

The “FULL NEED” energy (all sources combined), would correspond to 18 TWh / year (according to the Désertec project, here ...> )

I do not know how much it is in PET, I get lost in the orders of magnitude (and to compare with what the author of the thread says, but whatever).

Since we know that a 160 MW solar thermal power plant would cost $ 1 billion according to this post:
https://www.econologie.com/forums/post242187.html#242187

Reported in MWh / year, how many power stations of this type would it take to cover the FULL NEED?

Then it would be enough to divide the consumption per capita and per year, to see what total amount we would arrive ...? (After adding the equivalent KWh / year for domestic heating + sanitary water, and per capita, of course! Figure which is not included in these 400 €, but how much?)

So we could better assess the potential of this "solar thermal".

[...]

As far as I know gasoline cars and diesel vehicles (passenger cars and utility vehicles) still work on fuels.
The transition to electric is still extremely slow in fact.

and then the 400 € that you take back it was a post from 2007! : Cheesy:

I'm not saying that the subject of "FULL NEED" is not interesting, but there must be another adequate thread to talk about it, right?

New Arizona Concentrated Solar Power (CSP) Plant Keeps Producing Electricity After Sun Goes Down

03/10/2013 Evwind

Unlike other solar-powered electrical plants, the new Solana Concentrating Solar Power (CSP) keeps the sun's energy working after dark to produce electricity for APS customers across Arizona.

Unlike other solar-powered electrical plants, the new Solana Generating Station keeps the sun's energy working after dark to produce electricity for APS customers across Arizona.

Solana represents an important technological advance in solar energy production compared to the more-common photovoltaic technology, which needs direct sunlight in order to produce electricity. The three-square-mile facility near Gila Bend uses concentrated solar power (CSP) technology and thermal energy storage to capture the sun's heat to generate clean, renewable electricity.

This technology enables Solana to produce electricity at full capacity for up to six hours after sunset, including the early evening hours when customer demand for power typically peaks in Arizona.

“Solana is a monumental step forward in solar energy production,” said Don Brandt, APS President and Chief Executive Officer. “Solana delivers important value to APS customers by generating power when the sun isn't shining. It also increases our solar energy portfolio by nearly 50 percent. This provides a huge boost toward our goal to make Arizona the solar capital of America. ”

Solana is one of the largest power plants of its kind in the world with a capacity of 280 megawatts, enough to provide energy for 70,000 Arizona homes - a city the size of Yuma. APS is purchasing 100 percent of the output from Solana, which was constructed and is owned by Abengoa Solar.

The plant's CSP technology produces electricity by collecting the sun's heat to create steam that turns conventional turbines. The process begins with 2,700 parabolic trough mirrors, which follow the sun to focus its heat on a pipe containing a heat transfer fluid. This fluid, a synthetic oil, can reach at temperature of 735 degrees Fahrenheit. The heat transfer fluid then flows to steam boilers, where it heats water to create steam. The steam drives two 140-megawatt turbines to produce electricity, much like a traditional power plant.

What separates Solana from other solar power plants is the ability to store the heat from the sun up to six hours for electrical production at night. In addition to creating steam, the heat transfer fluid is used to heat molten salt in tanks adjacent to the steam boilers. The thermal energy storage system includes six pairs of hot and cold tanks with a capacity of 125,000 metric tons of salt, and the molten salt is kept at a minimum temperature of 530 degrees Fahrenheit.

When the sun goes down, the heat transfer fluid can be heated by the molten salt to create steam by running it through the tanks instead of the field of parabolic mirrors.

Abengoa's Arizona Solana solar power plant enters service

Oct 9, 2013 Reuters

Spanish technology and engineering company Abengoa SA said on Wednesday the 280-megawatt Solana solar thermal power plant in Arizona entered service earlier this week.

The plant, which cost about $ 2 billion to build, has a thermal energy storage system that is able to generate electricity for six hours after the sun goes down.

The plant is located near Gila Bend about 70 miles southwest of Phoenix.

Abengoa said the construction of the plant, which started in 2010, created more than 2,000 jobs.

The plant consists of parabolic shaped mirrors mounted on structures that track the sun and concentrate the sun's rays to heat water into steam to power a conventional turbine.

Arizona Public Service, a unit of Pinnacle West Capital Corp, will buy all the power produced by the plant for 30 years. The plant will generate enough power for about 70,000 people.

To help finance the plant's construction, the US Department of Energy gave Solana a $ 1.45 billion federal loan guarantee.

Last week, a unit of media holding company Liberty Interactive Corp invested $ 300 million in the Solana project.

Alstom obtains financing for its first solar power plant in Israel

09 July 2014 enerzine

Megalim Solar Power ** has announced that it has obtained funding from the European Investment Bank and Hapoalim Bank to build and operate the Ashalim thermodynamic solar power plant in Israel.
This new step follows the signing of an energy purchase contract between Megalim and the State of Israel in November 2013. It will allow the start of construction work for Ashalim, involving nearly 1.000 people, which should be completed in early 2017.

This project will bring Alstom's experience for the supply of turnkey power plants and the main electricity generation equipment, such as steam turbines and solar boilers, to BrightSource's solar field technology. As part of this contract, Alstom will provide engineering, supply and construction for the plant, and will provide all operating and maintenance services over a period of approximately 25 years. For its part, BrightSource will equip Ashalim with optical concentration devices and heliostats fields.

Image
.............

Ashalim will use BrightSource's concentrated solar tower technology, similar to that used on the Ivanpah project in southern California. More than 50.000 heliostats or mirrors, controlled by computer, will follow the sun in two axes and then reflect the sunlight towards a boiler located at the top of a 240-meter tower. The concentrated sunlight heats the water and generates superheated steam when it hits the boiler pipes. This high temperature steam is then extracted from the boiler and routed to a conventional turbine to generate electricity.

Located on 3,15 km² of land in the Negev desert, the Ashalim solar power plant, with a power of 121 MW, will produce enough electricity to meet the demand of more than 120.000 households.

Beginning of construction of a 200 MW concentrated solar power plant in the Gobi desert at ...... 2870 m above sea level.
With 15 hour heat storage capacity.
It will be the largest concentrated solar power plant in China


China's largest concentrated solar power tower plant starts construction with 200 MW

July 22, 2015 evwind

Construction has begun on China's largest concentrated solar power tower plant in the northwestern province of Qinghai.

Occupying 2,550 hectares of the Gobi Desert in Golmud City, the CSP plant will have an installed capacity of 200 megawatts, and be capable of supplying electricity to 1 million households, according to Qinghai Solar-Thermal Power Group.

“Its designed heat storage is 15 hours, thus, it can guarantee stable, continuous power generation,” said group board chair Wu Longyi.
Once operational, the plant will slash standard coal use by 4.26 million tons every year, reducing emissions of carbon dioxide and sulfur dioxide by 896,000 tons and 8,080 tons, respectively.
Using heliostats to focus sunlight onto a central tower for power generation, the solar power tower system boasts higher efficiency and better energy storage than the more commonly used trough system.

Located 2,870 meters above sea level on the Qinghai-Tibetan Plateau, Golmud has particularly favorable conditions for the developing new energy industry, said Wu Tianxiao, Communist Party of China Golmud deputy secretary.
The plant will also be China's first large-scale solar power plant under commercial operation, said Yu Mingzhen, vice director of Qinghai development and reform commission, heralding the project a landmark in China's solar energy development.

Such innovative companies working for the good of the environment should be saved by governments!

We have given tens of billions to the banks ... FOR NOTHING !!

Abengoa at least produced something other than speculation and financial swindle benefiting an extreme minority of Humanity!
