Dubai to Build World’s Largest Concentrated Solar Power Plant

Lorraine Chow | June 6, 2016 11:11 am

Dubai will soon be home to the world’s largest concentrated solar power plant.

The Dubai Water and Electricity Authority (DEWA) has announced the second phase of a massive solar project located in the Mohammed bin Rashid Al Maktoum Solar Park. According to a press release, the park is the largest single-site project to generate electricity from solar energy in the world, based on an independent power producer model.

The 13-megawatt first phase of the project has been operational since October 2013 and the 200-megawatt second phase will be operational by April 2017. The facility will ultimately produce 1,000 megawatts by 2020 and 5,000 megawatts by 2030, which will provide power for 800,000 homes. The solar park will help reduce 6.5 million tonnes of carbon emissions annually, the release said.

The project easily trounces the capacity of the world’s current record-holder, the Noor-Ouarzazate plant in Morocco which will have a 580-megawatt capacity by 2018.

DEWA has already received five bids from international companies for the Mohammed bin Rashid Al Maktoum Solar Park’s 800-megawatt third phase, with the lowest bid at USD 2.99 cents per kilowatt, a record-low price for solar power.

The ambitious project is part of the Dubai Clean Energy Strategy 2050, which aims to provide 7 percent of the emirate’s total power output from clean energy sources by 2020, 25 percent by 2030 and 75 percent by 2050, Saeed Mohammed Al Tayer, DEWA CEO and managing director, said in a statement.

In this June 2 post from DEWA’s Twitter account, Al Tayer announced the project:

The project is called a “concentrated solar plant” because it consists of a large number of movable mirrors, or heliostats, that can follow the sun’s path and harness sunlight to melt salt. The molten salt stores energy and can be used to power a steam turbine, allowing for energy production even when the sun isn’t shining.

“An important advantage of [concentrated solar power] is that thermal heat, which is used to produce electricity, can be stored easily, which makes it possible to produce electricity after sunset,” Al Tayer said. “The plant will have several thousand heliostats located around a tower that receives the radiation reflected by the heliostats which follow the sun’s movement. The heat-transfer fluid is then used to power the steam turbine to generate electricity.

“The project will use thermal storage for 8-12 hours daily, taking into account technical and economic factors. This will contribute to improving the effectiveness and efficiency of production and meet the requirements of the electricity grid. This in turn, will provide sustainable world-class energy supply for everyone in terms of availability and reliability, and support the sustainable development of the emirate. It will contribute to making Dubai the city with the lowest carbon footprint in the world by 2050.”


In addition to generating power, the facility features a solar-powered water pumping and desalination station that has a production capacity of 50 cubic meters of potable water a day, the press release stated.

Al Tayer said that DEWA is working to diversify Dubai’s energy mix to include 61 percent from natural gas, 25 percent from solar energy, 7 percent from coal and 7 percent from nuclear power by 2030. The reliance on clean energy sources will be increased incrementally to touch 75 percent by 2050, he added.

“Our wise leadership is pursuing the transformation towards clean and renewable energy to achieve a vision that recognizes their significance in achieving a balance between development and sustainability. This will help protect the rights of future generations to live in a clean, healthy and safe environment,” Al Tayer said.

Agelbert NOTE: Heliostats have a tremendous future in the high sunlight, dry areas of the planet. The Government of Dubai understands this.

There are now 226,852 heliostats in operation (Table 5) with a total mirror surface of about 3.3 millions of square meters. The figures for the heliostats to be implemented in the plants (and/or facilities) under construction are very similar: about 238,000 heliostats with a total surface of about 2 million square meters.

The total number of heliostats by adding the plants under development and planned to the operational and under construction plants, amounts to 835,838 heliostat units with a total mirror surface of about 17 million square meters.

Heliostats would not have been built in the first place if they weren't more cost effective than polluting fossil fuel power plants and dirty energy drilling operations. Heliostats are a welcome contribution to our renewable energy mix.

The fact that they are building so many more of them is evidence that they do produce cheaper Electricity than polluting energy sources. Anyone claiming otherwise is in error.

Fossil-fueled facilities are 17-34 times more dangerous to birds on a per GWh basis than wind power. Heliostats, LESS dangerous than wind power to birds, have caused the deaths of hundreds of birds and wind turbines may have killed about 7000 birds, but fossil-fueled stations killed 14.5 million and nuclear 327,000.

China will start up 20 solar thermal power plants by 2018: NEA
   
China will start up its first batch of 20 solar thermal power projects online by 2018, said the National Energy Administration(NEA) on Wednesday.

The projects with a total capacity of 1.35 gigawatt are concentrated in the five provinces that receive the most sunlight in the nation, Qinghai, Gansu, Hebei, Inner Mongolia and Xinjiang, said the NEA.

Solar thermal power plant use solar arrays to heat water that produces steam that runs turbines to produce electricity.

Power plants operators such as China General Nuclear Power Group, China Huaneng Group [HUANP.UL], China Guodian Corp [CNGUO.UL] and Zhejiang Supcon Solar Technology Co are involved, said the NEA.
 
These projects will collect a higher price from grid operators than traditional solar projects using photovoltaic cells at 1.15 yuan ($0.17) per kilowatt hour.
 
But that price level will be reduced in 2019 in accordance with the industry's development, said the National Development and Reform Commission (NDRC) in a statement released earlier this month.

Abu Dhabi's government-owned power utility has closed a 3.2 billion dirham ($872 million) financing package for what will be the world's largest solar power plant , the utility's top official said on Wednesday.

Abu Dhabi Water & Electricity Authority (ADWEA) raised $650 million in debt with the remaining $222 million raised in equity, Director General Saif Saleh al-Sayari told reporters.

A consortium of Japan's Marubeni Corp and China's JinkoSolar Holding were selected this year to build and operate the 1,177 megawatt plant.

“The financing which is completed is a $650 million project finance from local and international commercial banks,” al-Sayari said, adding that the 25-year loan is structured in a way that will allow refinancing after five years.

Bank of Tokyo Mitsubishi was the leading arranger of the loan along with three other Japanese banks – Sumitomo Mitsui Banking Corporation, Mitsubishi UFJ Trust and Norinchukin Bank.

French Banks – BNP Paribas Credit Agricole, Natixis - and First Abu Dhabi Bank were also part of the deal.

The equity portion will be contributed by ADWEA and the project developers Marubeni and JinkoSolar.

Construction of the independent solar plant with a capacity of 1,177 megawatts will begin immediately with completion scheduled for the second quarter of 2019.

The project is ADWEA'S first foray into renewable energy. Abu Dhabi aims to generate 7 percent of its energy from renewables by 2020; the government's green energy firm Masdar has launched renewable energy projects including solar plants.

The winning bidders offered to provide electricity for 2.42 cents per kilowatt hour, one of the most competitive prices seen in the solar industry.

A special purpose company, Sweihan PV Power Company, has been formed to operate the project, located east of the city of Abu Dhabi, capital of the United Arab Emirates. ADWEA holds 60 percent of the company while Marubeni and JinkoSolar each hold 20 percent.

Heliogen achieves solar 'breakthrough' that could replace 🦕🦖 fossil fuels in some industries  

Using advanced computer vision to reflect sunlight onto a target

By Shawn Knight on November 20, 2019, 12:30 PM



Something to look forward to: Clean energy company Heliogen has developed a technique for creating concentrated solar energy that could be used to replace fossil fuels in key industrial processes. Its secret? Advanced computer vision that helps to hyper-accurately align mirrors

Up to this point, commercial concentrating solar thermal systems have only been able to reach temperatures of up to 565 degrees Celsius. While handy, it’s not nearly hot enough for use in many industrial processes.

By using advanced computer vision software to accurately align a large array of mirrors to reflect sunlight onto a single target, Heliogen was able to hit temperatures exceeding 1,000 degrees Celsius. That’s warm enough to effectively replace the use of fossil fuels in the creation of things like steel, cement and petrochemicals and could drastically reduce global greenhouse gas emissions.


Heliogen founder and CEO Bill Gross said we’ve made great strides in deploying clean energy for electrical systems but notes that electricity only accounts for less than a quarter of global energy demand. “Heliogen represents a technological leap forward in addressing the other 75 percent of energy demand: the use of fossil fuels for industrial processes and transportation,” he added.

The startup has attracted the support of philanthropist Bill Gates.

“I’m pleased to have been an early backer of Bill Gross’s novel solar concentration technology,” Gates said. “Its capacity to achieve the high temperatures required for these processes is a promising development in the quest to one day replace fossil fuel.”

Heliogen’s roadmap outlines future processes that could bring the temperature up to 1,500 degrees Celsius which is hot enough to perform CO2 splitting and water splitting in the production of 100 percent fossil-free fuels like hydrogen and syngas.
