Large scale batteries for renewable energy storage now growing in use
Large Scale Energy Storage Roundup http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3755 23 May 13,
As the world increasingly moves towards renewable energy; it will need many individual energy storage locations distributed across the grid to address issues of variability in electricity production. The idea of a battery being a relatively small device or a series of small boxes cobbled together with wiring is changing fast. Batteries capable of storing huge amounts of energy are being developed using all sort of materials and technologies.
The following are just a few we’ve reported on in the past; some of which are have now been deployed in commercial applications: Continue reading
European countries can save €45bn by co-operative renewable energy
Siemens: Europe can save €45bn by optimising renewable energy generation 22 May 2013 http://www.renewableenergyfocus.com/view/32558/siemens-europe-can-save-45bn-by-optimising-renewable-energy-generation/ Siemens – which is hosting six Round Table discussions around the globe to discuss levers for optimising energy systems worldwide – says if regional characteristics were given higher priority when investments were made in renewable energy installations, Europe could save billions of Euros. The European energy system is inefficient to the point of damaging the continent’s competitiveness, it adds.
The company estimates that building and expanding renewable energy installations in the wrong locations is costing Europe around €45bn in unnecessary investment – the preliminary findings come via an ongoing studySiemens is conducting with the Technical University of Munich to examine energy systems worldwide. Significantly, the €45bn figure includes associated extension of the power grid.
In Germany alone, the potential savings are possible on a magnitude of 4-5 times the annual investment in solar and wind power plant construction, the firm says. The crux, according to Siemens, lies in the choice of location: installations must be built at the sites in Europe that offer the highest power yields. Continue reading
Renewable energy – Germany’s impressive export of electricity
Germany Continues to Export Power Despite Nuclear Exit http://climatecrocks.com/2013/05/21/germany-continues-to-export-power-despite-nuclear-exit/ Climate Denial Crock of the Week with Peter Sinclair May 21, 2013
They said it couldn’t happen. They keep trying to trash the EnergieWende – Germany’s planet-leading transformation to renewable energy. But the pesky Germans keep perking along. Wall Street Journal:
FRANKFURT–Germany exported more electricity than it imported for the seventh consecutive year in 2012, despite an accelerated exit from nuclear-power generation that included the immediate and permanent shut-down of nearly half of the country’s atomic reactors in 2011.
Germany exported about 22.8 terrawatt-hours of electricity more than it imported in 2012, the Federal Statistics Office, Destatis, said Tuesday in a written statement.
The main destinations for German-produced electricity were the Netherlands, Switzerland and Austria, said the statistics office, citing data supplied by Germany’s four power transmission grid operators. The main sources of power imports into Germany were France, Denmark and the Czech Republic, it said.
The statistics office didn’t provide any reasons for the continued power exports, despite the fact that Germany shut down eight of 17 nuclear reactors in the wake of the Fukushima disaster in Japan in March 2011.
The rapid expansion of solar- and wind-power installations are seen as the main reason for continued German electricity exports, as well as the erosion of wholesale power prices under which many of Europe’s utilities are presently suffering.
A top market for solar energy – Japan
Japan emerges as solar beacon, SMH May 22, 2013 – ”……The country’s generous solar feed-in tariff continues to bolster demand: Japan Asia Group’s plans are moving ahead to develop 500 megawatts of solar projects over the next three years, Tetsuo Yamashita, chairman of the company, said at a meeting with analysts on 16 May. It has 24 solar plants already developed in Europe, but may trim its business in that region, Yamashita said. Japan Asia received a 1.6 billion yen loan for five solar projects in its home country from Shinsei Bank and Mitsubishi UFJ Lease & Finance Company, it said in a statement in March.
The preceding day, Eurus Energy Holdings announced plans to build a 115MW solar power station in northern Japan. The aim is to start construction of the 49 billion yen ($US480 billion) project this July and to begin running the station in November 2015. Eurus is a venture between Toyota Tsusho Corporation and Tokyo Electric Power Company (Tepco).
And on 14 May, Nippon Paper Industries said that its joint venture with Mitsubishi will begin construction on a 21MW solar power station in western Japan this autumn. The plant is expected to start selling electricity to Shikoku Electric Power in H2 2014.
Demand for solar power is increasing for non-residential projects, according to data released by the Ministry of Economy, Trade and Industry on 17 May. Approved applications for non-residential solar projects jumped to 11GW by the end of February from just under 6GW at the end of January.
The start of the feed-in tariff last year helped Sharp to reduce losses at its solar unit in the Asian country: global solar sales climbed 16 per cent to 260 billion yen ($US2.54 billion) last fiscal year, mainly driven by an increase in residential demand in Japan, the company said. Sharp’s operating losses fell to 4.4 billion yen ($US43 billion) for the 12 months ended 31 March compared with 21.9 billion yen ($US210 billion) the previous year….. Japan is forecast to install 6-9.4GW of solar capacity this year under its feed-in tariff, according to Bloomberg New Energy Finance. This could make it the second-largest – or even the top – solar market in theworld
Renewable energy could be boosted by Compressed Air Storage
Compressed Air Storage Could Boost U.S. Renewable Energy Uptake http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3752 21 May 13, New U.S. research into storing energy in underground caverns in the form of compressed air could lead to improved uptake of utility scale wind power in America’s Northwest.
A study by the Department of Energy’s Pacific Northwest National Laboratory and Bonneville Power Administration has found that compressed air energy storage (CAES) has the capacity to store wind power for up to 85,000 homes in two specific geologic areas of inland Washington and Oregon.
CAES storage helps solve the problem of intermittency in renewable energy generation. When the wind powers turbines, or the sun shines on a solar power plant, electricity is abundant and must be stored for later use.
CAES works by using excess energy from a power plant to pump compressed air deep into an underground storage structure such as porous rock, where it remains until needed. The pressurised air is then released back to the surface where it drives a turbine to generate electricity for the grid, thus providing a constant flow of energy.
Study manager for the BPA, Steve Knudsen, believes that with 13 percent of the Northwest’s power supply coming from wind energy sources, CAES technology will become a valuable tool in helping the states meet Renewable Portfolio Standards, which require 20 to 30 percent of all electricity come from variable sources such as wind and the sun.
There are just two CAES plants in the world and both are man-made, one in Alabama and one in Germany. The PNNL/BPA research looked instead for natural geologic formations in Oregon and Washington, finding seams of porous volcanic basalt rock, 450 metres below the surface and at least 10 metres thick.
So far two promising locations have been identified. One is the Columbia Hills Site in Oregon, which is near a natural gas pipeline and could be paired with a CAES system to provide up to 40 days of continual energy storage. The other is the Yakima Minerals Site, which would use geothermal power and CAES technology in a hybrid power plant and utilising geothermal energy to cool the facility’s air compressors, increasing their efficiency.
Germany continues move to clean energy, though it is not easy
Germany grapples with nuclear energy phaseout The Local Germany’s energy transition project – in which nuclear power will be phased out and replaced with energy from renewable sources – is facing the challenges of cheap coal, unresolved energy storage and an out-of-date electricity grid. 20 May 13 “…The hard-to-predict flow of renewable energies compared to fossil or nuclear power is one of the many challenges of the energy transition which Chancellor Angela Merkel rang in following Japan’s 2011 Fukushima nuclear disaster.
The goal is to be nuclear-free by 2022 and to combat pollution and climate change by boosting the share of clean and safe renewables to 80 percent by 2050.
Across Germany, solar panels, made popular by state subsidies and falling unit prices, now cover many home roofs and stretches of farmland.
New laws have allowed home owners to sell excess power back into the grid, while other incentives promote home insulation and other efficiency gains.
Germany’s solar power capacity has risen exponentially to reach a current level of about 30 gigawatts. Another 25 to 30 gigawatts come from wind farms across vast
stretches of Germany’s flat, coastal north and offshore parks in the North and Baltic seas.
Merkel, a physicist by training, said last week that, under optimal conditions, the total now falls just shy of Germany’s usual demand of 65 to 70 gigawatts Continue reading
Japan set to become a top solar energy market in 2013
Goldman Sachs eyes Japan renewable energy investments http://www.eco-business.com/news/goldman-sachs-eyes-japan-renewable-energy-investments/ 20 May 13,
Goldman Sachs Group Inc. (GS) plans to invest as much as 50 billion yen ($487 million) in renewable energy projects in Japan in the next five years, tapping demand for electricity produced from solar and wind-power generators.
The Wall Street firm also plans to take as much as 250 billion yen of bank loans and project-financing over the same period to move ahead with projects that would cost a total of 300 billion yen, Hiroko Matsumoto, a Tokyo-based spokeswoman for Goldman, said by telephone. The Nikkei newspaper reported the plan earlier today.
Japan began offering incentives in July through feed-in tariffs to encourage renewables after the Fukushima nuclear-plant crisis stemming from the March 11, 2011 earthquake and tsunami. Japan has been forced to slash its reliance on atomic power generation since Fukushima.
“We believe that we can leverage our global expertise in investing in renewable energy in places such as the US and India, to help expand Japan’s renewable power capabilities,” Ankur Sahu, co-head of the merchant banking division in the Asia-Pacific, said by e-mail.
Goldman Sachs formed the Japan Renewable Energy Co. unit in August to plan, design and operate power plants run on sun, wind, fuel cells and biomass fuels, it said on its website.
Investor attraction
Renewable energy has attracted interest from investors ranging from billionaire Masayoshi Son’s Softbank Corp. and financial-services company Orix Corp. to the country’s biggest banks led by Mizuho Financial Group Inc.
Japan will probably become the largest solar market in the world after China this year, according to data compiled by Bloomberg.
Commercial and utility-scale projects will boost solar installations to a range of 6.1 gigawatts to 9.4 gigawatts in 2013, exceeding an earlier forecast of 3.2 gigawatts to 4 gigawatts, Bloomberg New Energy Finance said in April.
Companies that stand to benefit include Kyocera Corp., Sharp Corp. and Suntech Power Japan Corp., all of which make and sell solar panels for residential and industrial use.
US Department of Defense (DOD) world’s biggest consumer of solar energy
US Military on Track to Reach 3 GW of Solar Energy by 2025, The Energy Collective, 20 May 13 The Army, Navy and Air Force are using more than 130 megawatts of solar for everything from powering remote special operations to air conditioning and lighting for U.S. base residences. And the forces intend to keep building toward 3 gigawatts of solar capacity by 2025 as part of a much bigger Department of Defense (DOD) commitment.
While detractors were declaring solar too intermittent to be reliable at home, U.S. Marines were successfully relying on it at battlefield sites in the Khyber Pass, according to Enlisting the Sun: Powering the U.S. Military with Solar Energy, a new report from the Solar Energy Industries Association (SEIA), released just in time for Armed Forces Day on May 18.
The DOD’s annual $20 billion energy budget makes it the biggest single energy consumer in the world……http://theenergycollective.com/hermantrabish/226186/us-military-3-gw-solar-energy
Printing solar photovoltaic cells – an Australian breakthrough
“We’re using the same techniques that you would use if you were screen printing an image on to a T-Shirt,” he says.
VIDEO Printing Australia’s Largest Solar Cells http://cleantechnica.com/2013/05/19/printing-australias-largest-solar-cells/#I2hPrL1dDL6WTXwD.99 20 May 13, Scientists have produced the largest flexible, plastic solar cells in Australia – 10 times the size of what they were previously able to – thanks to a new solar cell printer that has been installed at CSIRO. The printer has allowed researchers from the Victorian Organic Solar Cell Consortium (VICOSC) – a collaboration between CSIRO, The University of Melbourne, Monash University and industry partners – to print organic photovoltaic cells the size of an A3 sheet of paper.
According to CSIRO materials scientist Dr Scott Watkins, printing cells on such a large scale opens up a huge range of possibilities for pilot applications.
“There are so many things we can do with cells this size,” he says. “We can set them into advertising signage, powering lights and other interactive elements. We can even embed them into laptop cases to provide backup power for the machine inside.”….. Continue reading
Walmart going solar in a big way, in Massachusetts.
Walmart Adds More Solar In Massachusetts http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3744 17 May 13, U.S. retail giant Walmart has taken another step towards its goal of becoming 100 percent supplied by renewable energy, announcing the completion of rooftop solar power systems on eight of its stores across Massachusetts.
The solar power generated by each system will provide an estimated 10 to 15 percent of each store’s electricity needs.
The announcement was made at the launch of the company’s Walpole store, which features a 374-kilowatt rooftop system, with 1337 solar panels generating 383,551 kilowatt hours of electricity per year.
The eight Walmart stores used almost 10,000 solar panels in their PV arrays, providing a combined 2.8 million kilowatt hours of solar electricity and avoiding almost 1,500 metric tons of carbon dioxide emissions; earning Walmart the Environment Protection Agency’s top ranking as number one on-site green power generator/consumer in the U.S in 2013.
“The stores in Massachusetts demonstrate our commitment to increasing the share of renewable energy that powers our stores and improving energy efficiency,” said David Ozment, senior director of energy at Walmart.
Massachusetts Department of Energy Resources Commissioner, Mark Sylvia said, “Investments from business leaders like Walmart have helped the Commonwealth meet our 250 megawatt solar goal four years early and earn the number one national ranking in energy efficiency two years in a row.”
Walmart used Connecticut solar installer Greenskies Renewable Energy to complete the project, and a power purchase agreement will see the company buy all the electricity generated by the system.
With a stated goal to source 100 percent of its power from renewables, Walmart now has 280 renewable energy projects in operation and under development worldwide, supplying one billion kilowatt hours of electricity to its stores annually. Onsite renewable projects such as solar, wind and fuel cell technology account for around four percent, while the company’s current total of 21 percent renewable electricity as of the end of 2012 is made up from grid-connected utility-scale renewable sources.
Enormous solar rooftop system for Hyundai, South Korea
Hyundai To Install 40,000 Solar Panels On South Korean Plant http://www.energymatters.com.au/index.php?main_page=news_article&article_id=3740 15 May 13, South Korea’s largest automaker, Hyundai, announced last week it will install the nation’s largest rooftop photovoltaic power plant at its manufacturing factory in Asan, Korea.
Hyundai says it plans to install 40,000 solar photovoltaic modules on the rooftops of Asan’s press, welding, assembly and engine buildings by the end of 2013.
In total, the panels will occupy just shy of 145,000 square meters (14.5 hectares) of the building’s massive 213,000 square metre rooftop area.
The 10MW rooftop solar power facility will generate approximately 11.5 million kilowatt-hours of electricity per year; enough to supply the power needs of 3,200 households. At that generation level, 5,600 tons of carbon dioxide emissions will be avoided annually.
The shading provided by the panels, plus the arrays’ sprinkler cooling systems will also help reduce the temperature in the plant below; offering some energy savings.
Korea Electric Power Corporation (KEPCO) will purchase the electricity produced by the solar modules.
The type of panels to be used on the facility is unknown and while it wouldn’t be unreasonable to assume Hyundai solar panels will be the choice; Hyundai Solar is a totally separate company run under different ownership – it is a subsidiary of Hyundai Heavy Industries.
Hyundai joins a growing list of automakers turning to solar energy for powering operations or providing an additional revenue stream.
While Hyundai’s Asan project is utility scale, commercial and manufacturing operations large and small can benefit from installing solar panels.
According to Australian commercial solar provider Energy Matters; which specialises in systems with a capacity of 20 kilowatts to 1 megawatt, if businesses are paying more than 20c/kWh for daytime electricity rates, a system sized to daytime load will provide a payback time of between 5 and 7 years – after which time, the electricity generated is essentially free.
Bloomington City goes for 100% renewable energy in electricity aggregation
City opts for renewable energy, civic fee in electric aggregation Pantagraph.com 13 May 13, BLOOMINGTON — The city’s electricity aggregation program will include 100 percent renewable energy and a fee to reimburse the city for administrative costs.
The City Council on Monday authorized Mayor Tari Renner and Deputy City Manager Barb Adkins to sign bid documents related to the program that will allow the city to bundle Ameren customers’ electricity needs to attract the lowest bid. The two city officials are expected to accept a bid on May 15.
With seven “yes” votes, aldermen approved the inclusion of 100 percent renewable energy at an expected cost of $0.0008 per kilowatt hour.
They also approved a civic contribution of $0.001 per kilowatt hour. The civic contribution would provide the city with up to about $250,000 in revenue.
Mayor Tari Renner said he sees the civic contribution as a “user fee” to cover administrative costs of implementing the program.
City Manager David Hales said he could not at this time provide an estimate of how much the city’s involvement in the program will cost, but the city could be involved in energy efficiency educational efforts going forward. He said staff involvement to date has been “considerable.”…… Bloomington voters in April approved a referendum allowing the city to enter into an electricity aggregation program…… http://www.pantagraph.com/news/local/city-opts-for-renewable-energy-civic-fee-in-electric-aggregation/article_211277e0-bc3d-11e2-bf0f-0019bb2963f4.html
Renewable energy forecasting technologies coming
Breakthrough Renewable Energy Forecasting Coming to Grid by 2015 The Energy Collective, Silvio Marcacci May 13, 2013 Breakthrough renewable energy forecasting technologies may be two years away from revolutionizing the efficiency of wind and solar generation on America’s grid. The National Center for Atmospheric Research (NCAR) is adding to its already impressive list of renewable energy innovations with a new two-year plan to develop custom forecasting systems for wind energy and solar power.
NCAR scientists and engineers will develop technology to improve wind power output by predicting sudden changes in wind speed, help wind farm operators avoid curtailment during icy conditions, and predict the amount of energy generated by small-scale solar energy installations…….
The new phase of renewable energy forecasting technology will provide “probabilistic forecasts,” meaning utility managers will be able to make decisions based on high-accuracy predictions of certain weather conditions at a wind farm on the next day. Forecasts will focus on wind “ramp” events, ice and extreme temperatures, and distributed solar.
Anticipating Wind Ramp Events
Of the three, predicting ramp events could mean the most for overall generation. Ramp events refer to sudden and significant changes in wind conditions over the span of a few hours due to passing weather fronts or atmospheric events. NCAR’s Variational Doppler Radar Analysis System (VDRAS) will combine radar data with computer simulations to create accurate forecasts for specific wind farms and reduce intermittency…….
Preventing Cold-Weather Effects On Turbines……
Predicting Small-Scale Solar Output…..
NCAR’s approach to renewable energy forecasting has already been proven to save millions. A wind forecasting system it developed for Xcel in 2010 saved utility customers over $6 million that year by developing 35% more accurate forecasts for wind farm output.
“By creating more detailed and accurate forecasts…we can produce a major return on investment,” said Thomas Bogdan, President of the University Corporation for Atmospheric Research. “This type of cutting-edge research helps make renewable energy more cost competitive.” http://theenergycollective.com/silviomarcacci/223186/breakthrough-renewable-energy-forecasting-coming-us-grid-2015
Small scale solar power to take off in a big way in Dubai
Dubai looks to rooftop solar power revolution, The National, Florian Neuhof May 13, 2013 , Dubai is finalising legislation that will enable property owners to feed solar power into the grid and may even allow them to make money from it. The Government last year unveiled plans for a 1,000-megawatt solar park, but it believes that small-scale applications are important for meeting its renewable energy targets.
“In the near future we will have a legislative environment that allows for grid-connected solar power. There will be different approaches for different scales,” said Ivano Iannelli, the chief executive of the government-owned advisory company Dubai Carbon Centre of Excellence.
“In the next 12 months, we will see a constant increase of solar infrastructure. Not only standalone facilities such as solar pumps, but to actually power our villas, our parks, our residential communities.”
Industry sources say that encouraging the use of solar on rooftops is one of the pillars of Dubai’s plans to bring the technology to the emirate. Photovoltaic panels can be mounted on roofs of residential properties, office buildings or industrial facilities, providing electricity and creating a surplus that can be fed into the grid…… After decades of relying on fossil fuels, Dubai has now woken up to the potential of solar power.
The emirate seeks to generate 5 per cent of its electricity from the sun by 2030. Last year, the Dubai Supreme Council for Energy announced plans for the Mohammad bin Rashid Al Maktoum Solar Park, and Dewa awarded the contract for the first array in October.
While solar is a clean source of energy, it is also an increasingly viable alternative to scarce natural gas. http://www.thenational.ae/thenationalconversation/industry-insights/energy/dubai-looks-to-rooftop-solar-power-
Solar and Wind Energy Up – Nuclear and Coal dowm
Wind, Solar, & Natural Gas Up In Europe — Coal & Nuclear Down http://cleantechnica.com/2013/05/13/wind-solar-natural-gas-up-in-europe-coal-nuclear-down/#xMfKPr55HOwV0sP4.99 (Good graphics in this article) May 13, 2013 Zachary Shahan Following up on the report I just published regarding EPIA’s 2012–2017 European and global solar PV report, below are some really interesting charts I wanted to highlight. Basically, they show that solar PV, wind power, and natural gas capacity has grown substantially in the EU while coal, nuclear, and oil capacity has fallen.
Compared to 2011, a shift has also occurred within the top three. More wind power came online in 2012 than in 2011, while the net increase in natural gas capacity was much smaller. (Notably, I noted back in December 2011 that wind power was pricing natural gas out of the market in Germany. I imagine the same thing was happening in other countries.) http://cleantechnica.com/2013/05/13/wind-solar-natural-gas-up-in-europe-coal-nuclear-down/#xMfKPr55HOwV0sP4.99
