New Battery Could Lead to Cheaper, More Efficient Solar Energy

In Solar News on February 27, 2012 at 18:10

A joint research project between the University of Southampton and lithium battery technology company REAPsystems has found that a new type of battery has the potential to improve the efficiency and reduce the cost of solar power.

The research project, sponsored by REAPsystems, was led by MSc Sustainable Energy Technologies student, Yue Wu and his supervisors Dr Carlos Ponce de Leon, Professor Tom Markvart and Dr John Low (currently working at the University’s Research Institute for Industry, RIfI). The study looked specifically into the use of lithium batteries as an energy storage device in photovoltaic systems.

Student Yue Wu says, “Lead acid batteries are traditionally the energy storage device used for most photovoltaic systems. However, as an energy storage device, lithium batteries, especially the LiFePO4batteries we used, have more favourable characteristics.”

Data was collected by connecting a lithium iron phosphate battery to a photovoltaic system attached to one of the University’s buildings, using a specifically designed battery management system supplied by REAPsystems.

Yue adds, “the research showed that the lithium battery has an energy efficiency of 95 per cent whereas the lead-acid batteries commonly used today only have around 80 per cent. The weight of the lithium batteries is lower and they have a longer life span than the lead-acid batteries reaching up to 1,600 charge/discharge cycles, meaning they would need to be replaced less frequently.”

Although the battery will require further testing before being put into commercial photovoltaic systems the research has shown that the LiFePO4 battery has the potential to improve the efficiency of solar power systems and help to reduce the costs of both their installation and upkeep. Dr Carlos Ponce de Leon and Dr. John Low now plan to take this project further with a new cohort of Masters students.

Dr Dennis Doerffel, founder of REAPsystems and former researcher at the University of Southampton, says: “For all kinds of energy source (renewable or non-renewable), the energy storage device — such as a battery — plays an important role in determining the energy utilisation. Compared with traditional lead acid batteries, LiFePO4 batteries are more efficient, have a longer lifetime, are lighter and cost less per unit. We can see the potential of this battery being used widely in photovoltaic application, and other renewable energy systems.”

Lessons from Spain

In Solar News on March 9, 2010 at 00:34

Two years ago, this gritty mining city hosted a brief 21st-century gold rush. Long famous for coal, Puertollano discovered another energy source it had overlooked: the relentless, scorching sun.

Armed with generous incentives from the Spanish government to jump-start a national solar energy industry, the city set out to replace its failing coal economy by attracting solar companies, with a campaign slogan: “The Sun Moves Us.”

Soon, Puertollano, home to the Museum of the Mining Industry, had two enormous solar power plants, factories making solar panels and silicon wafers, and clean energy research institutes. Half the solar power installed globally in 2008 was installed in Spain.

Farmers sold land for solar plants. Boutiques opened. And people from all over the world, seeing business opportunities, moved to the city, which had suffered from 20 percent unemployment and a population exodus.

But as low-quality, poorly designed solar plants sprang up on Spain’s plateaus, Spanish officials came to realize that they would have to subsidize many of them indefinitely, and that the industry they had created might never produce efficient green energy on its own.

In September the government abruptly changed course, cutting payments and capping solar construction. Puertollano’s brief boom turned bust. Factories and stores shut, thousands of workers lost jobs, foreign companies and banks abandoned contracts that had already been negotiated.

“We lost the opportunity to be at the vanguard of renewables — we were not only generating electricity, but also a strong economy,” said Joaquín Carlos Hermoso Murillo, Puertollano’s mayor since 2004. “Why are they limiting solar power, when the sun is unlimited?”

Puertollano’s wrenching fall points to the delicate policy calculations needed to stimulate nascent solar industries and create green jobs, and might serve as a cautionary tale for the United States, where a similar exercise is now under way.

For now, electricity generation from the sun’s rays needs to be subsidized because it requires the purchase of new equipment and investment in evolving technologies. But costs are rapidly dropping. And regulators are still learning how to structure stimulus payments so that they yield a stable green industry that supports itself, rather than just costly energy and an economic flash in the pan like Spain’s.

“The industry as a whole learned a lot from what happened in Spain,” said Cassidy DeLine, who analyzes the European solar market for Emerging Energy Research, a firm based in Cambridge, Mass. She noted that other countries had since set subsidies lower and issued stricter standards for solar plants.

Yet, despite the pain that Spain’s incentives ended up causing, in many ways they fulfilled their promise, Ms. DeLine said.

“Even though incentives can create bubbles and bursts, without them this industry won’t take off,” she said. “The U.S. is really behind Europe on this, and if we wait until solar is cost-competitive on its own, we may miss the boat and an opportunity to shape the market.”

The most robust Spanish solar companies survived the downturn, have restructured and are re-emerging as global players.

For example, when the government changed course, Siliken Renewable Energy, originally a producer of solar panels, shut its factories for five months and cut its staff to 600 from 1,200. But after shifting its focus to external markets like Italy, France and the United States, and diversifying into solar support services, the company now turns a profit.

“We were a company that banks trusted, so we could make the shift,” said Antonio Navarro, a company spokesman. “But a lot of little companies disappeared.”

The period was particularly difficult because it coincided with the global economic crisis, he said.

To encourage development of solar power and reduce dependence on fossil fuels, Europe has generally relied on so-called feed-in tariffs, through which governments pay a hefty premium for electricity from renewable resources. Regulators in the United States have favored less direct incentives like requiring municipalities to buy a percentage of their electricity from companies making renewable energy, although a few cities and states, most notably Vermont, are experimenting with the feed-in concept.

When it was announced in the summer of 2007, Spain’s premium payment for solar power was the most generous anywhere — 58 cents per kilowatt-hour — with few strings attached.

In retrospect it was far too high. “Everyone from all over the world was installing in Spain as fast as they could, and every biologist who could add was working in solar,” said Pedro Banda, director general of the Institute of Concentration Photovoltaic Systems, one of the research institutes in Puertollano.

Even inefficient, poorly designed plants could make a profit, and speculation in solar building permits was common.

Although Spain’s long-term goal had been to produce 400 megawatts of electricity from solar panels by 2010, it reached that milestone by the end of 2007.

In 2008 the nation connected 2.5 gigawatts of solar power into its grid, more than quintupling its previous capacity and making it second to Germany, the world leader. But many of the hastily opened plants offered no hope of being cost-competitive with conventional power, being poorly designed or located where sunshine was inadequate, for example.

Designs for solar power plants vary. The most common type uses photovoltaic panels to generate electricity. Others, called thermal solar plants, use mirrors to focus the sun’s energy on a liquid that, when heated, drives a steam turbine.

In its haste to create a solar industry, Spain made some miscalculations: solar plants can be set up so quickly and easily that the rush into the industry was much faster than anticipated. And the lavish subsidies inflated Spanish solar installation costs at a time when they were rapidly decreasing elsewhere — in part because of increasing competition from panel makers in China, but also because higher volumes produced economies of scale.

In Spain, the tariff, now adjusted quarterly, is about 39 cents per kilowatt-hour for electricity from freestanding solar power plants, and slightly higher for panels on rooftops.

Germany’s tariff, 53 cents per kilowatt-hour, is expected to fall at least 15 percent this summer, and there are proposals before Parliament to eliminate subsidies for solar plants on farmland.

The bonus payments required to make solar energy financially viable vary, depending on local sunshine and the cost of conventional energy. Experts predict that, possibly by next year, Italy will be the first place where solar-generated electricity will not need subsidies to compete with electricity from fossil fuel. Italy has abundant sun and sky-high energy rates, given that it imports most of its fossil fuel.

Even with the reduced incentives and local economic downturn, the solar industry gave Puertollano something of a face-lift and, potentially, a new economic future. Research institutes there are developing cutting-edge technologies. Unemployment, though now up around 10 percent, has not returned to the 20 percent figure. The city is home to a number of solar businesses: a new 50-megawatt thermal-solar plant owned by the Spanish energy giant Iberdrola created hundreds of jobs.

Although coal mines still dot the landscape and a petrochemical factory remains one of Puertollano’s largest employers, that new solar plant sits just next door, with more than 100,000 parabolic mirrors in neat rows on about 400 acres of former farmland. Clean and white as a hospital ward, it silently turns sunshine into Spanish electricity.

Walmart Canada Plans Wind, Solar Projects In Ontario

In Solar News on March 9, 2010 at 00:20

Walmart Canada is planning to install a rooftop solar system as well as a wind turbine at two separate Walmart Canada locations in Ontario. Construction of the two systems is expected to begin this year, with a combined investment of approximately $2m.

Under the proposed projects, the company will finance and own the solar energy and wind turbine systems. Power generated will be returned to the electrical grid under Ontario’s feed-in tariff program for renewable energy. Walmart Canada will use these pilot projects to assess the effectiveness of these systems to power some of its stores in future.

Once complete, the rooftop solar power generating system is expected to generate 450,000kWh of energy per year. The solar system will also reduce greenhouse gas emissions by an estimated 80 tonnes per year, the company said.

Walmart Canada plans to install a 20kW wind turbine adjacent to one of its Ontario stores. The system is expected to generate as much as 50,000kWh of electricity per year. The wind turbine has been designed for low wind speed areas, where wind power has not been previously practical, and can operate in wind speeds as low as 10km per hour.

Solar from Space

In Solar News on January 25, 2010 at 08:43

Europe’s biggest space company is seeking partners to fly a demonstration solar power mission in orbit.

EADS Astrium says the satellite system would collect the Sun’s energy and transmit it to Earth via an infrared laser, to provide electricity.

Space solar power has been talked about for more than 30 years. However, there have always been question marks over its cost, efficiency and safety.

But Astrium believes the technology is close to proving its maturity.

“Today we are not at an operational stage; it’s just a test,” said chief executive officer Francois Auque. “In order to implement a solution, of course, we would need to find partnerships and to invest, to develop operational systems,” he told BBC News.

Those partnerships could comprise space agencies, the EU or national governments and even power companies, he said.

Space solar power is an attractive concept because it would be clean, inexhaustible, and available 24 hours a day.

The amount of energy falling on photovoltaic cells placed in orbit is considerably greater than the same solar panels positioned on the Earth’s surface. In space, the incidence of light is unaffected by clouds, dust or the filtering effects of atmospheric gases.

Critics, though, have always pointed to multiple hurdles – to the cost of launching and assembling large solar stations in orbit, to the losses in efficiency in conversion, and to the safety issues surrounding some wireless transmission methods, particularly those that use microwaves.

Astrium says the latter can be addressed by using infrared lasers which, if misdirected, would not risk “cooking” anyone in their path.

The company has already tested power transmission via laser in its labs, and is now working on improving the efficiencies of the end-to-end system.

Robert Laine, Astrium’s chief technology officer, acknowledges however that there are still some big challenges to be overcome.

“Today, we will be limited in power by the size of the laser we can build. That’s a prime limitation,” he said.

“On the receive side, the conversion of this infrared energy into electricity – that’s something which is progressing very fast and we are working with the University of Surrey [in the UK] to develop converters.

“The principle is to get a very high efficiency of conversion of the infrared [laser light] into electricity. If we achieve 80% then it’s a real winner.”

Dr Laine said a small demonstration of the technology ought to be ready for launch in the coming decade.

“Like any technology, someone has to demonstrate it first before it can become an operational system,” he told BBC News.

“We have reached a point where, in the next five years, we could build something which is in the order of 10-20 kW to transmit useful energy to the ground.”

Samsung Deal Questioned

In Solar News on January 25, 2010 at 08:32

Canadian-based green power firms say the lucrative deal Ontario has signed with Samsung Group will give the South Korean company an unfair advantage in the key Ontario renewable energy market.

Under the $7-billion agreement with Samsung and Korea Electric Power Corp. , announced last week, the Ontario government will pay $437-million in incentives if the consortium completes four manufacturing plants in the province. These plants will make wind-turbine towers and blades, and solar inverters and modules.

In addition, Samsung’s planned 2,500 megawatts of wind and solar power projects will get the same high electricity rates the province is paying to anyone who generates solar or wind power under Ontario’s “feed-in-tariff” program in its Green Energy Act.

Many developers and manufacturers with plans to expand in Ontario expressed shock and surprise that Samsung is receiving hundreds of millions of dollars in extra incentives they can’t get.

While the provincial government has said it wants to build a domestic green-energy industry, this private deal with a foreign entity has raised concerns among Canadian firms who expected a level playing field.

“It basically gives an unfair competitive advantage to Samsung because they have decided to be both a manufacturer and a developer, where as other manufacturers who are looking at Ontario and planning on making substantial investments and creating jobs … won’t get the same benefits,” said Kerry Adler, chief executive officer of solar farm developer SkyPower Corp.

The deal appears to discriminate against existing players such as SkyPower, Mr. Adler said. “We intend to buy [solar] panels from Canadian manufacturers, so shouldn’t [we] also be receiving some form of economic [bonus] if we buy from Ontario? What’s the difference? The only difference is that Samsung is doing both, when there is a whole community of manufacturers who just manufacture and a whole community of developers who just develop.”

One Canadian firm that is considering setting up shop in Ontario is Bromont-Que.-based wind-turbine manufacturer AAER Inc. . Chief financial officer Eric Phaneuf said he was surprised by the way Ontario’s private deal with Samsung was negotiated, and suggested it isn’t consistent with the “openness and transparency” of the program in place for other players.

Michael Carten, executive chairman of Calgary-based solar inverter maker Sustainable Energy Technologies Ltd., said he too is puzzled by the huge incentive being offered only to Samsung.

The Korean company is unlikely to be conducting any research and development in Canada, Mr. Carten said, so it may contribute less to the province’s economic development than some local players who aren’t getting an extra subsidy. “It mystifies me why it is a one-off deal.”

Last October, his company announced it will build inverters for the North American market in Ontario, partly because it expects a surge in demand due to the local content requirements in the province’s feed-in-tariff program. Now, Mr. Carten said he intends to write to provincial official to ask for the same kind of financial incentives Samsung is getting. “I would hope that the province would say to[us]: ‘Yeah, you too.’ ”

Mr. Carten, like many other green-energy players, is also concerned Ontario is giving the Samsung group priority access to the electrical transmission grid in the province.

Limited capacity in the grid is a bottleneck slowing some renewable energy projects. “I’m not sure I go along with carving up access to the grid when there is not enough access to go around,” Mr. Carten said. “I don’t know how you explain this to other guys.”

Tim Stephure, an analyst at Emerging Energy Research in Cambridge, Mass., said the Samsung deal appears to encourage companies to negotiate individual deals with the Ontario government, rather than play by the transparent rules set out in the Green Energy Act.

“[The Samsung deal] might provide the industry with a bit of a sugar high in the near term, but it doesn’t provide a lot of confidence in the province … to administer the program it designed,” he said.

Mr. Stephure also questioned Ontario’s ability to compete with incentives put in place by the Obama administration to encourage green jobs in the United States. Those programs are more transparent and even-handed, he said, and actually add up to higher subsidies than what is being given to Samsung.

Suzuki School Features Solar

In Solar News on January 25, 2010 at 08:19

The Dr. David Suzuki Public School in Canada has begun featuring solar photovoltaic technology developed by Canadian-based solar integrator, Carmanah Technologies.

According to officials, the Greater Essex County District School Board of Windsor, Ontario, is receiving a 32 kW grid-tied Photovoltaic system with funding provided by the Government of Ontario Green Schools Initiative. The new 58,000 square foot Public School in Windsor, Ontario, named after environmentalist, Dr. David Suzuki, will serve as both a learning tool for students as well as a standing demonstration of environmental design for the architectural and engineering community. The addition of the grid-tied solar PV system, valued at approximately $400,000 (CDN), will support the school’s goal of obtaining LEED Platinum certification, the nation’s highest level of certification for green building design.

The school said that the new roof-top mounted grid-tie solar photovoltaic system is a functional power source, meeting approximately 10 per cent of the School’s electrical needs. According to Carmanah CEO, Ted Lattimore, the system will contribute to the spirit of environmental stewardship that the Dr. David Suzuki Public School aspires to embody. “The 32 kW panels are affixed to the roof, but the design also extends the system downwards to form a canopy over the main entry of the building. This serves as a symbol to visitors and students of the Public School’s commitment to environmental building design. At the same time, the panel’s placement optimizes the system’s performance with increased solar exposure.”

The Greater Essex County District School Board hopes to incorporate the new technologies in both student academia and culture; providing information kiosks throughout the building and a website that will inform students and guests about the energy and environmental technologies being employed. “We believe it is important to teach children about alternative energy sources as well as energy conservation,” stated Giuliana Hinchliffe, Coordinator of Engineering, Facility Services Department, Greater Essex County District School Board. “We wanted to create a building that inspires and teaches the spirit of earth stewardship, which we feel the School embodies.”

5 MW Solar Plant for Thar Desert, India

In Solar News on January 13, 2010 at 08:21

Esar Solar Power (ESP) and Fidelis Energy are to develop a US$25 million, 5MW solar power plant in the Thar Desert near Jaisalmer, India. Fidelis will design and construct a multi-megawatt solar power system. ESP has signed a 10-year power purchase and sale agreement with the state’s government-owned power distribution company.

“India represents the first of many untapped solar power markets that Fidelis plans to enter in 2010 and 2011,” said James Poole, CEO of Fidelis Energy Inc. “While international projects pose special challenges for solar energy producers, such as identifying proper high voltage lines and the ownership of the property prior to system installation.”

“We recognize that the continued use of fossil fuels negatively impacts both the economy and the environment,” said Esar Solar Power Chairman Jagdish Singh. “As such, ESP is determined to meet a portion of India’s energy requirements by developing several large solar photovoltaic projects (PV Projects), which will generate electricity from sunlight. Fidelis has shown that it has the ability and innovative construction techniques to execute this contract, and we look forward to this project beginning in May of 2010,” added Singh.

The project is expected to be completed by October, 2010.

Renewable Energy ‘Supergrid’ coming to Europe

In Solar News on January 13, 2010 at 08:10

A European “supergrid” may soon be a reality.  UK’s energy and climate change minister, Lord Hunt shares this opinion: “We recognise that the North Sea has huge resources, we are exploiting those in the UK quite intensively at the moment. But there are projects where it might make sense to join up with other countries, so this comes at a very good time for us.” Lord Hunt is talking about several North Sea countries that have coalesced for a good cause. They are aiming to create a clean and green supergrid. This supergrid will be connected to wind farms of Scotland, solar panels of Germany and hydro-electric dams of Norway. This project will be ready soon and then the first green European electricity grid will become a reality. They have expanded a network of thousands of kilometers of highly efficient undersea cables. These network cables will cost around €30bn. This way renewable energy generated in any of the North Sea countries will be available to many.

The supergrid will also perform the task of a gigantic 30GW battery for Europe’s alternative and clean energy. This grid will store electricity when energy demand is low. The North Sea grid would also operate as a spine of the future European electricity supergrid, where more energy will be produced from renewable energy sources. They are also trying to overcome the problem of unreliability associated with alternative energy. This supergird will have electricity available in all types of unpredictable weather because at least one phenomenon of nature will be happening such as blowing wind, lapping waves or shiny sun. Justin Wilkes, is the policy director of the European Wind Energy Association (EWEA). He said, “If Europe is able to develop a super-grid it will be a vital ingredient in the fight against climate change because it will allow large-scale integration of renewable electricity production.”

This project involves the participation of nine governments of Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden and Ireland and the UK. This project will lay a milestone to the oath, European Union took, that by 2020 they will meet 20% of their energy needs from alternative sources of energy.

Hydro powered plants of Norway are equal to about 30 large coal-fired power stations. They can utilize extra energy to pump water uphill. That water will fall down again creating the necessary force to generate electricity when there is a laxity in demand. Wilkes says, “The benefits of an offshore supergrid are not simply to allow offshore wind farms to connect; if you have additional capacity, which you will do within these lines, it will allow power trading between countries and that improves EU competitiveness.”

The EWEA has conducted a study regarding the costs of connecting the proposed 100GW wind farms and building interconnectors. These interconnectors will also accommodate wind and wave power farms in future. This cost will be around €30bn. Lord Hunt is talking about the plan, “The first thing we’re aiming for is a common vision. We will hopefully sign a memorandum of understanding in the autumn with ministers setting out what we’re trying to do and how we plan to do it.”

Hunt agreed that the European supergrid will be a long term project but it will not remain in its planning phase only. They will take a concrete shape in future. Hunt agreed that The UK, like other countries, faced “huge challenges with our renewables targets. The 2020 target is just the beginning and then we’ve got to aim for 2050 with a decarbonised electricity supply – so we need all the renewables we can get.”
