This was proposed in 2009 so I imagine it is operational by now. I found this amazing document that I need to look at more, but it is a listing of all the large solar facilities maybe in the world? Anyway if you want to see cool photos go to the site because pictures are a pain.

General Description of Project

On August 10, 2009, Abengoa Solar Inc., the sole member of Mojave Solar LLC, filed an Application For Certification (AFC) for its Abengoa Mojave Solar Project. The proposed project is a nominal 250 megawatt (MW) solar electric generating facility to be located near Harper Dry Lake in an unincorporated area of San Bernardino County. The project would be located approximately halfway between Barstow, CA and Kramer Junction, CA, and is approximately nine miles northwest of Hinkley, CA.

The project will implement well-established parabolic trough technology to solar heat a heat transfer fluid (HTF). This hot HTF will generate steam in solar steam generators, which will expand through a steam turbine generator to produce electrical power from twin, independently-operable solar fields, each feeding a 125-MW power island. The sun will provide 100 percent of the power supplied to the project through solar-thermal collectors; no supplementary fossil-based energy source (like natural gas) is proposed for electrical power production.

World’s largest solar plant gets U.S. OK

$6 billion project in Calif. aims to power at least 300,000 homes

msnbc.com staff and news service reports

updated 10/25/2010 6:07:03 PM ET

WASHINGTON — Calling it a major milestone, the Obama administration on Monday approved what investors say will be the world’s largest concentrated solar power plant and one that more than doubles all of U.S. solar output and can power at least 300,000 homes.

The project in the Mojave Desert near Blythe, Calif., is the sixth solar venture authorized on federal lands within the last month. All are in desert areas.

“The Blythe Solar Power Project is a major milestone in our nation’s renewable energy economy and shows that the United States intends to compete and lead in the technologies of the future,” Interior Secretary Ken Salazar said in announcing the approval.

Construction on the $6 billion plant is expected to start by the end of 2010, with production starting in 2013. Developer Solar Millennium, a company based in Germany, says the plant will generate 1,066 construction jobs and 295 permanent jobs.

The project had run into opposition by some environmentalists due to wildlife concerns.

This is just such a beautiful installation. It takes up too much bandwidth to show pictures but here is a written description.

http://www.torresolenergy.com/TORRESOL/gemasolar-plant/en

Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology.

Characteristics of Gemasolar:

  • Rated electrical power: 19.9 MW
  • Net electrical production expected: 110 GWh/year
  • Solar field: 2,650 heliostats on 185 hectares
  • Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.

The prolongation of the plant’s operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar’s output much higher than that which is delivered by other technologies in a facility with the same power.

The notable increase in the plant’s power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies. The plant will thus supply clean, safe power to 25,000 homes and reduce atmospheric CO2 emissions by more than 30,000 tons a year.

The power generated by Gemasolar will be sent through a high-tension line to the substation of Villanueva del Rey (Andalusia, Spain), where it will be injected into the grid.

Australia poised to take the lead in solar energy market

– July 16, 2012

Yingli Green Energy notes the solar energy potential of the country

Over the past decade, Australia has shown modest support for alternative energy. In recent years, this support has been growing at a rapid pace, with the country now showing major interest in solar energy. Because of Australia’s exposure to solar radiation, it is one of the most attractive locations in terms of a solar energy market. Yingli Green Energy, a Chinese solar panel manufacturer, believes that the potential for solar energy in Australia is so high that it may become the leader of the photovoltaic mass market by the end of the year.

Australia could benefit from Chinese manufactured solar technologies

Solar energy has been growing in strength all over the world. Demand for solar energy systems is growing amongst consumers who wish to see savings of their energy bills as well as help the environment. As demand for solar energy systems rises, so too does the supply of these energy systems. China has played a large role in the growing availability of solar energy systems. The country has thrown its manufacturing might behind the production of solar panels and other technologies, inundating the mass market with products that are driving down the price of solar energy systems.

Company expects solar energy market prospects to be extraordinary

Yingli Green Energy is one of the three largest solar panel manufacturers in China, as well as the rest of the world. Though the company has a small presence in Australia, it claims that the country could become a world leader in terms of solar energy in the coming years. The company expects Australia to see major progress in the solar energy market by the end of the year, with its prospects becoming “quite extraordinary” in 2014 and 2015.

Yah right. That is so laughable. Even after they announced that they were going to try to bring 5 nuclear plants on line there were no commercial backers and so the price went up before they even started. It has been all downhill since then.

News Guide: Nuclear Industry Facing Cost Pressures

By The Associated Press
July 10, 2012 (AP)

Q: How many nuclear plants are under construction in the U.S.?

A: Three. Two nuclear reactors are being built at Plant Vogtle in eastern Georgia. Two more reactors are under construction at Plant Summer in central South Carolina. A fifth reactor mothballed in 1985 is being finished at Plant Watts Bar in Tennessee.

Q: How often are nuclear plants built?

A: The last nuclear plant built in the United States was the existing reactor finished at Watts Bar in 1996.

Q: How much does a nuclear plant cost?

A: Billions of dollars. Nuclear plants are among the most complicated and expensive infrastructure projects in the world. The plants require incredible amounts of design and engineering work and must be built to exacting safety standards. Federal inspectors can require that parts of the plant be ripped out and replaced if they don’t meet muster. The plants require huge amounts of metal, concrete, cables and wires. Building two Westinghouse Electric Co. AP1000 reactors at Plant Vogtle is supposed to cost roughly $14 billion, though the final expenses could be more.

Is Tidal Energy Coming – According to this the answer is yes

Tapping The Source: The Power Of The Oceans

Posted by Big Gav in , , , , , ,

Last year I came across the story of Dutch company Kema and their energy island idea – basically a variant on the usual pumped hydro energy storage concept where water is pumped out of a space below sea level then allowed to flow back in, generating power as it does. The “island” uses wind power to pump water out of the enclosed area. An obvious extension to this idea would be to harness ocean energy as well – letting wave and/or tidal power supplement the output of the wind turbines. An attraction of this concept is that it potentially allows a large amount of new energy storage to be brought online – and this storage would be along the world’s coastlines, where most of the population lives.


Another form of energy island has been in the news recently, this one a substantially more ambitious proposal which envisions artificial islands to collect wind, wave, ocean current and solar power in the tropics, along with a more unusual energy source – harnessing the difference in water temperatures between the warm surface and the cold depths using a technique called OTEC (Ocean Thermal Energy Conversion). These islands are being proposed by architects Dominic Michaelis and his son Alex Michaelin as a response to Richard Branson’s Virgin Earth Challenge, which offers $25 million in prizes for innovative solutions for combating global warming.

While the practicality of these particular proposals has yet to be put to the test, the various forms of ocean power are probably the most overlooked of the big 6 renewable energy sources (along with solar, wind, geothermal, biomass and hydro).

India Must Somehow Get Power For 4 Hundred Million People – Is the answer solar

Posted on by

They have more people without electricity then there are in the United States. MAN! So solar might seem inadequate but I do not think so. I believe if China keeps pumping out the panels.

India’s per capita consumption of electricity per is around 481 units or one-fifth of world average of 2596 units. Compare it to 900 units per month consumption of electricity in US. Such a low electricity use in India adds to the challenge of development because in order for India to be energy secure, the country needs to first match its supply of power with the demand. In addition, it must add the capacity year on year with respect to the gross domestic product (GDP) growth rate, power being a primary ingredient in economic development.

Gap between supply and demand of power

LOADS DEMAND AVAILABILITY DEFICIT
BASE LOAD 861,591 (MU) 788,355 MU 8.5%
PEAK LOAD 122 GW 110 GW 9.8%

Source: CEA report, 2011

Solar power in the renewable energy mix

India needs to sustain an 8% to 10% economic growth rate, over the next 25 years, and it needs, at the very least, to increase its primary energy supply. Fortunately there is an abundance of solar energy across India. About 5000 trillion kWh per year energy is incident over India’s land area with most parts receiving 4-7 kWh per square mile per day. The annual average global solar radiation on horizontal surfaces, incident over India is about 5.5 kWh per square metre per day or 1650 Kwh per square metre per year.

Fortunately there is an abundance of solar energy across India.

Based on such promising solar energy potential across India, the government of India rolled out

Based on such promising solar energy potential across India, the government of India rolled out the central policy “Jawaharlal Nehru National Solar Mission: JNNSM” on 23 November, 2009 to add 20,000MW grid-connected solar power capacity, which is 27.62% in grid-connected renewable power capacity by 2022.  However, along with the central policy, 3 states (Rajasthan, Gujarat, and Karnataka) have come up with their state solar policies that are independent or concurrent to central policy while other states are planning their solar policies such that the total contribution of solar will be much higher in the renewable power mix. Therefore, the percentage of renewable power in the cumulative grid-connected power capacity will be increased.

Longterm Storage Is Not An Issue – It never has been for renewable energy

This is actually part of a lecture that I give to college students called the Myths of Global Warming. The point of it is that Global Warming is indeed happening and at an accelerated pace. The point is that there have been myths erected like barricades that defend the use of fossil fuels. Here is a high tech version.

Super Hot Salt: The Newest Energy Storage Innovation?

Policymakers and energy industry experts often talk about clean energy as though it isn’t reliable. In fact, while an MIT study recently found the existing grid would probably be up to the challenge of absorbing clean energy, intermittency does present a real challenge that renewables must address to get to high levels of penetration.

But BrightSource Energy, a major player in the market for concentrating solar power, or CSP, recently announced the installation of new thermal energy storage technology at three of its planned power plants in California. This thermal energy storage technology will go a long way toward solving the intermittency problem for concentrating solar power. BrightSource’s announcement demonstrates that we can in fact get reliable baseload power from the sun [or, even better, load-following power].

The thermal energy storage systems, built using SolarPLUS technology, work by using hundreds of parabolic mirrors to concentrate the rays of the sun on a tank of molten salts, heating the salts to several hundred degrees above the boiling point of water. The superheated salt is then stored in a giant insulated container until the power plant needs to add additional output, at which point it can use the heat stored in the molten salt to boil water to create steam to drive its turbines.

Cool Green Cars – I haven’t done any car posts this year

Posted on by

I usually do a series of car posts every year, and maybe this is the time to do it. I know starting on a Friday is kind of obtuse but heh it gives me a couple of days to look at cools sites and cars before I do another post. These are hybrids but the real moves have been in all electric.

Five Hybrid Concept Cars We REALLY Want To Drive

Jun 22, 2012

Every now and then, we allow our thoughts to drift here at GreenCarReports.

Naturally, we’re thinking forward rather than back, and often to the cars we might be driving around in five or ten years time.

We’ve compiled a list of five concept cars seen at auto shows over the last year or so. All are hybrids, and all showcase exciting new visions of styling and technology that could well hit the roads in the near future.

Hyundai i-Oniq

Given the meteoric rise of Korean brands Hyundai and Kia over the last few decades, it’s only right that they should play a part in our future too. The i-Oniq concept car, revealed at the 2012 Geneva Motor Show back in March, is a sleek, two-door range-extended hybrid.

Though the styling evokes images of a huge engine under the hood, the concept uses a tiny 1.0-liter 3-cylinder unit, supplying power to a 107-horsepower electric motor when its 75-mile battery range is depleted. We’re pretty confident that 75 miles would cover most of our day-to-day driving, but that little gasoline engine would provide a useful extra 360 miles.

And you know what? It looks pretty good too.

The method they are using here is preferable to simply drilling a well anywhere and trying to bury it in the ground. The oil in spent fields never will get out and there was plenty of pressure, so this at least seems safe.

Transporting CO2 to Gulf States Could Boost U.S. Oil Production by 20 Million Barrels a Year

ROCKPORT, Ind., June 22, 2012 /PRNewswire-USNewswire/ — Indiana Gasification welcomed today’s Federal Register publication by the U.S. Department of Energy of an amended notice of intent (NOI) to include an approximately 440 mile CO2 pipeline in the environmental impact statement (EIS) required for DOE financial backing of IG’s state-of-the-art clean fuels facility.

The DOE publication marks the most recent regulatory development in support of the plant, which will be the cleanest coal-fired facility ever built in the United States. In the last two months, the Indiana Department of Environmental Management has filed a proposed clean air permit with the U.S. Environmental Protection Agency and issued a draft Clean Water Act permit.

In the Notice of Intent, the Department of Energy acknowledges that the proposed project with the CO2 pipeline qualifies for financing under the 2008 appropriations act providing authority for industrial gasification activities. Further, the DOE has determined that the project meets two goals of the Title XVII Loan Guarantee Program, encouraging the commercial use of new or significantly improved technology and achieving substantial environmental benefits.
