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).

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.

First U.S. Tidal Power Project Readies for Launch in Maine

Posted July 24, 2012 in Solving Global Warming

The ocean is a tremendous bank of energy. Covering more than two-thirds of our planet, the amount of energy embodied in the ocean’s tides, currents, and waves, not to mention temperature and salinity gradients, could power the world—if we were able to commercialize the technology to harness its renewable power.

While technologies harnessing energy from tides and currents have been domestically discussed for decades, no project has ever reached commercial development, and been connected to the grid in the United States. In Eastport, Maine, however, that changed today that will change around mid-August with the launch of the Ocean Renewable Power Company (ORPC) TidGen Cobscook Bay tidal energy project. Harnessing the power of the massive tidal shifts in Cobscook Bay, an inlet connected to the much larger Bay of Fundy, the project is the first in the U.S. to receive a FERC license, negotiate a power purchase agreement, and install and operate a power-producing tidal generator.

As clean energy advocates, we are excited to highlight new, innovative projects that inject clean power and jobs into communities, deploy American ingenuity and know-how and utilize smart clean energy policies. The DOE invested $10 million in the project as part of its larger water power program that aims to better understand the environmental impacts that come with harnessing ocean energy, as well as refine, and make more cost-effective, the technologies that do so.

In addition to harnessing local sources of energy, the project apparently:

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.

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).

Smart Grid Efforts Breed Parasites – Blame monopoly capitalism

If the utility companies were smart they would have been in the forefront of this effort, but years of being monopolies have sucked their brains out of their ears. So now we are going to have parasites festering all over the new grid. This can not be good. That is obviously not how this author sees it.

A startup emerges to help time shift energy use

By Jul. 5, 2012, 12:00am PT

Dialing down your home’s energy consumption during times of peak power grid use in exchange for compensation is an emerging service. Picture it’s a hot day and you agree not to jack up your air conditioner in exchange for a discount on your utility bill. Startups like new-comer Smart Grid Billing are developing applications to help manage this process, and later this month Smart Grid Billing plans to launch a field trial of its service at a golf course.

Founded in 2009, Smart Grid Billing is testing its combination of energy-monitoring wireless-connected plugs and software that collect and crunch energy consumption data. The service stores the data in a central server and can determine which appliance or equipment has the potential to reduce or cut its electricity use in real time.

This block of unused power can be sold to a local grid operator. Smart Grid Billing shares the revenue from that sale to its customers, and the plugs are programmed to restore the electricity flow back to the equipment at a later time.
