Abengoa Solar inaugurates second-generation high-temperature solar power tower

Abengoa Solar’s (Seville, Spain) first high-temperature power tower, dubbed “Eureka,” was unveiled on June 19th, 2009 by Martín Soler Márquez, Director of Innovation, Science and Enterprise for the Andalusian Regional Government, the company reports in a press release. According to the press release, this power tower is intended to test a new type of receiver on an experimental basis and it is expected that the receiver can achieve the higher temperatures needed for higher-efficiency thermodynamic power cycles. The aim of this new technology is to increase plant performance, thereby reducing generating costs as well as the area of the solar field, Abengoa reports.

The new experimental plant occupies a 16,000-squarefoot portion of the Solúcar Platform and uses 35 heliostats and a 164-foot tower which houses the experimental superheating receiver. The capacity of the experimental plant which features a thermal energy storage system is estimated to be about 2 megawatts (MW).

Solúcar Platform solar thermal and PV installation complex to offset 185,000 tons of CO2 emissions per year.

eSolar’s Chinese partner makes a successful bid for solar thermal project in Fuxin City

Just three months ago, California CSP manufacturer eSolar licesed its power tower technology to China’s Pengai Electric – the partnership has born fruit. The partnership has announced its second CSP project in northern China.

Shandong Penglai Electric Power Equipment Manufacturing (SPEPEMC), the Chinese partner company of Pasadena power tower developer eSolar, signed a cooperation agreement in mid-March with the City of Fuxin, Liaoning Province to build the Fuxin Solar Thermal Power Project. Pengai Electric will build the plant in three phases. When complete the solar thermal power station will have a generation capacity of 300 MW. The Fuxin project is the second for Penglai Electric since the privately-owned power company signed a licensing agreement with California company eSolar last January. Under the terms of the agreement, the Chinese company comitted to building 2 GW of solar thermal power stations in China by 2021 using eSolar’s power-tower technology. The first plant slated for construction is a 92 MW CSP plant to be located at the 66-square-mile Yulin Energy Park in the Mongolian desert.

In eSolar’s power towers, flat mirrors focused on two recievers at the top of a tower heat water directly to produce steam and drive the plant’s turbine. The Chinese plants will combine the eSolar technology with biomass-fired power plants to produce electricity in poor weather conditions and after sundown.

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 The Start Of A Solar Power Meditation – Harvesting the power of the sun

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.

When The Oil Runs Out – Capitalism goes down with it

People are always playing out this dystopian vision of what the world will look like if there is a sharp break in the availability of fossil fuels. Most people imagine guys with guns will control their chunk of the world and abuse everyone in it for the own good. Or that we will break into semi-dead towns and farm life like 200 years ago. But, I usually say, what if it is slower than that and what if people cooperate instead of foolishly compete. Then life might look like this, which sounds kinda fun.

Ithaca Ecovillage Forges a Path to Sustainable Living

By Coralie Tripier

ITHACA, New York, Jul 16 2012 (IPS) – Ecovillage at Ithaca (EVI), located in the beautiful Finger Lakes region of upstate New York, is an intentional community of 160 people striving for greater sustainability, a better quality of life, and perhaps even a new model for urban planners the world over.

Enjoying breathtaking surroundings, residents wander around the village on pedestrian-only streets, swim in the pond, share meals in the common house, and spend a small amount of their time working together for their community.

EVI’s residents have to volunteer for two hours every week in one of the six work teams – the cooking team, the dishwashing team, the common house cleanup team, the outdoor maintenance team, the regular maintenance team, or the finance team.

“If you had a house, you would have to do that anyway, so why not do it for the broader community and make friends at the same time,” Ashley Click, a young mother and new resident at EVI, told IPS.

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.

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

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.

Written by Varun Mittal | 02 July 2012

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%

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.

Healthcare Upheld – But that is not what I am going to post about

It has been the shipping industry’s wet dream for a hundred years, Wind Power. They dream back to the days when the only costs for shipping was the ship and port fees. I do not know if this is the system that will catch on but it is pretty cool nonetheless.

Wind-Powered Cargo Ships Make a Comeback

February 28, 2011 By

Sailing ships once carried much of the world’s cargo across the seas, until canvas sheets were replaced by low-grade “bunker” oil. Now it appears that wind power is about to make a comeback, in the form of rigid “sails” that double as solar panels. The patent-pending technology, called the Aquarius Solar and Wind Marine Power System, is being developed by a company called Eco Marine Power. The dream of a high tech, sustainable energy cargo ship has been percolating for a number of years now, but it hasn’t caught on in a big way, so let’s see if this new system is The One.

Wind Power for Cargo Ships

At first blush, wind power for today’s ultra-huge cargo ships looks like a nice idea, but just not possible. The scale alone makes it seem impractical. However, that hasn’t stopped anyone from trying. In recent years a German company has come up with a parachute-like design for cargo ships that includes sails the size of football fields, and a British company has developed a more traditionally styled, rigging-free sail system for smaller cargo ships.
