Barbara Eldredge for Curbed: Imaginative architect and designer Carlo Ratti has had some bonkers ideas over the past year, including an exercise-powered gym barge and a mile-high skyscraper park. But his latest project is on the sunnier side of feasibility. Literally.
The Sun&Shade is a light-reflecting canopy made of mirrors that automatically rotate to catch the sun’s rays and fling them at a photovoltaic panel, “located a safe distance away.” This generates clean electricity up top while cooling the shaded area beneath. A working prototype of the mirrored structure just debuted at Dubai’s Museum of the Future as part of its “Reimagining Climate Change.” Cont'd...
Lorraine Chow for EcoWatch: The race to build the world's largest solar power plant is heating up. California-based energy company SolarReserve announced plans for a massive concentrated solar power (CSP) plant in Nevada that claims to be the largest of its kind once built.
SolarReserve CEO Kevin Smith told the Las Vegas Review-Journal that the $5 billion endeavor would generate between 1,500 and 2,000 megawatts of power, enough to power about 1 million homes. That amount of power is as much as a nuclear power plant, or the 2,000-megawatt Hoover Dam and far bigger than any other existing solar facility on Earth, the Review-Journal pointed out.
"It's a big project," Smith told the publication. "It's an ambitious project." Cont'd...
The 13th five-year National Development Plan initiated by the National Energy Administration (NEA) for the National Development and Reform Commission (NDRC) set the goal to install Concentrated Solar Power (CSP) plants with a total capacity of 10 Gigawatt by 2020 in China.
George Dvorsky for Gizmodo: They like to do things big in Dubai, including a newly-approved concentrated solar power project that will generate 1,000 megawatts of power by 2020—and a whopping 5,000 megawatts by 2030.
The Dubai Water and Electricity Authority (DEWA) has announced the launch of the world’s largest concentrated solar power (CSP) project. Located on a single site within the Mohammed Bin Rashid Al Maktoum Solar Park, the plant will consist of five facilities. The first phase of the project is expected to be completed either in late 2020 or 2021, at which time it’s expected to generate 1,000 MW of power. By 2030, this plant could be churning out five times that amount—enough to raise the emirate’s total power output by 25 percent.
By comparison the Ivanpah CSP in California (which is currently the world’s largest) generates about 392 MW of power. Morocco’s Ouarzazate solar power plant will provide about 580 MW of power once it’s complete in 2020. Cont'd...
Justin Worland for Time: Crescent Dunes looks and sounds a bit like an invention lifted from a science fiction novel. Deep in the Nevada desert more than 10,000 mirrors—each the size of a highway billboard—neatly encircle a giant 640-foot tower. It looks like it might be used to communicate with aliens in deep space.
But the engineers and financiers behind the facility, located in the desert about halfway between Las Vegas and Reno, say the power plant’s promise is anything but fiction. The solar power facility built and operated by the company SolarReserve can power 75,000 homes. What sets it apart from other big solar projects is that this plant can store power for use when it is most needed, including cloudy days and after dark—a major advance for renewable energy technology.

A recent research paper published in Applied Thermal Engineering highlights the importance of defined protocols to effectively flush and clean newly built facilities, which is needed prior to filling the system with expensive fluids, such as solar thermal fluids.
Naser Al Wasmi for The National UAE: Masdar Institute scientists have published a breakthrough research into more efficient solar power – and they will not have to look far for the raw material needed.
Using sand, they hope to drive concentrated solar power technology to compete with the traditional photovoltaic method.
Named “Sandstock”, the research published at the Solar Power and Chemical Energy Systems Conference in South Africa yesterday, showed sand can withstand temperatures of up to 1,000°C.
Concentrated solar power, or CSP, uses mirrors to reflect heat from the sun to one point, most typically a tower filled with a material capable of storing heat and then converting it into electricity.
CSP’s benefit is that the energy derived is easy to store, but in recent years it has lost out to the more popular photovoltaics, which is more cost-efficient.
That may now change.
“Sand is really always a drawback in this country but in this project we wanted to use it as an advantage because it can withstand very high temperature, and of course it is very cheap here,” said Dr Nicolas Calvet, assistant professor of mechanical and materials engineering, and guide for the research project.

Cole Mellino for EcoWatch: Morocco imports 97 percent of its energy, and yet it has one of the highest rates of solarinsolation of any country—about 3,000 hours of sunshine per year, according to the Solar GCC Alliance. To put that in perspective, the Guinness Book of World Records puts Yuma, Arizona as the sunniest place on Earth with an average of 4,055 hours of sunshine per year (the theoretical maximum is 4,456), whereas the sunniest place in Germany, which still has a robust solar industry, gets a mere 1,800 sunshine hours a year. So it’s no surprise that Morocco is tapping into its abundant sunshine for energy.
Morocco is building “a complex of four linked solar mega-plants that, alongside hydro andwind, will help provide nearly half of Morocco’s electricity from renewables by 2020,” reports The Guardian. When the entire project is finished, it will be the world’s largest concentrated solar power plant in the world. The first phase, Noor 1, will go live next month. Cont'd...
By Lauren J. Young for IEEE Spectrum: Today’s concentrator photovoltaic (CPV) technologies have shown promising potential for more efficient solar power. The latest systems are said to be capable of handling the power of a hundred suns. Yet prototypes have failed to compete with cheaper flat panel solar systems that dominate the market. The U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) is determined to push CPV to the next level. On 24 August, at the Clean Energy Summit, U.S. President Barack Obama and Energy Secretary Ernest Monizannounced a program called MOSAIC that will invest $24 million into CPV solar technology development.
Why can’t today’s CPV systems compete? The concentrators can only convert direct sunlight into energy, missing out on the large fraction of sunlight diffracted by clouds and the atmosphere. Manufacturing costs of concentrator apparatuses have also prevented CPV from reaching mass production. Cont'd...
Joe Romm for ThinkProgress: Solar photovoltaic (PV) systems have seen explosive growth because of their stunning 99 percent price drop in the past quarter century. As a result, the other form of solar power — concentrating solar thermal power (CSP) — is a small fraction of the solar market.
But the International Energy Agency (IEA) says CSP has a very bright future too because it enables cheap, efficient storage, which allows CSP plants to provide electricity long after the sun has set. According to the IEA’s 2014 CSP Technology Roadmap, 11 percent of global electricity will be generated by concentrating solar thermal power in 2050. Cont'd...
