Tesla already has reservations for $1bn worth of energy storage
Tesla has taken 100,000 reservations for its Powerpack and Powerwall battery products, worth approximately $1bn, according to founder Elon Musk.
Speaking on the company’s quarterly earnings call, Musk said Tesla had taken reservations (non-binding agreements) which led him to believe the company would sell $50m of storage in the fourth quarter of 2015, and up to $500m in both 2016 and 2017.
Musk said: "If you just take the reservations that have been made thus far, it's well over $1 billion worth of Powerpacks and Powerwalls. And that's with no marketing, no advertising, no sales force to speak of, really, we're not trying to sell it".
Tesla chief technology officer Jeffrey Straubel, who was also on the call, said that around 70% of the reservations were for the larger 1MW Powerpack system, which is focused at commercial users and large-scale energy generators. Cont'd...
Norway Could Provide 20,000MW of Energy Storage to Europe
Mike Stone for GTM: Norway has a lot of hydroelectric plants: a total of 937 of them, which provide a population of 5 million with around 98 percent of its electricity. In fact, the Scandinavian country is home to roughly half of all the hydroelectric water storage reservoirs in Europe.
This vast system could also offer a Europe a substantial amount of energy storage -- up to 20 gigawatts of it -- if an ambitious scheme currently being proposed can overcome political and social hurdles and get the necessary funding. That’s according to Kaspar Vereide, an engineer at the Norwegian University of Science and Technology in Trondheim. And his models suggest it could all be achieved in seven years.
Vereide is not alone in thinking Norway could become a vast green battery for Europe. The Centre for Environmental Design of Renewable Energy has concluded that there are four realistic scenarios for pumped hydro energy storage in the country, ranging from a Nordics-only scenario, where Norway only looks after its own needs, plus some of those of its Scandinavian neighbors; to a so-called ‘big storage’ scenario, which, it says, would see “Norwegian hydropower play an important role in integrating variable renewable sources into the European power system by providing large volumes of balancing over various time horizons to the North Sea countries through highly integrated grids and power markets.”
It’s this "big storage" scenario -- with Norway becoming "the green battery of Europe" -- that Vereide has in mind. Cont'd...
Battery Costs Set To Fall 60% By 2020 From Energy Storage 'Megashift'
By Sophie Vorrath for RenewEconomy: The key role energy storage will play in the electricity grids of the future – and the vital importance of investing in and testing the various emerging battery storage technologies – has been highlighted in a major report published by the Australian Renewable Energy Agency on Monday, which predicts a 40-60 per cent price plunge for certain battery technologies by 2020.
The 130-page report prepared by AECOM predicts a “mega-shift” to energy storage adoption, driven by demand – from both the supply side, as networks work to adapt to increasing distributed and renewable energy capacity, and from consumers wishing to store their solar energy – and by the rapidly changing economic proposition; a proposition, the report says, that will see the costs of lithium-ion batteries fall by 60 per cent in less than five years, and by 40 per cent for flow batteries.

China is building the world's largest solar power plant
Oliver W heaton for Metro.co.uk: The massive solar plant, which will stretch out across the Gobi desert in the country’s Quinghai province, will cover 25 square kilometres of vacant ground space.
When finished the plant, called Delingha, is expected to have a capacity of 200 megawatts, which means it will power one million households all year round.
Delingha is the world’s first solar power plant to be run as a commercial entity after being jointly developed by BrightSource Energy from California and the Shanghai Electric Group in China.
The awesome structure will have six huge towers as well as thousands of solar mirrors which, due to their heat storage time of 15 hours, will be able to guarantee ‘stable and continual power generation’, according to Qinghai Solar-Thermal Power Group board chair, Wu Longyi. Cont'd...
Japan Builds World's Largest Floating Wind Turbine off Fukushima
by ARATA YAMAMOTO for NBC News: Engineers in Japan have installed the world's largest floating wind turbine, a towering 344-foot structure that is billed as being able to withstand 65-foot waves and even tsunamis.
The 7 megawatt turbine was fastened to the seabed last week by four 20-ton anchors about 12 miles off the Fukushima coast.
Its installation was delayed four times because of consecutive typhoons in the region. But one of its chief engineers, Katsunobu Shimizu, told NBC News that the turbine — which is about the same height as London's St. Paul's Cathedral — would be able to withstand even the most extreme conditions.
"These turbines and anchors are designed to withstand 65-foot waves," Shimizu said during a sea tour of the turbine given from a boat off the coast. "Also, here we can get 32-foot-tall tsunamis. That's why the chains are deliberately slackened."
If a large wave were to push the turbine up, down or to the side, the loose chains connecting the structure to the seabed would give it the freedom to move without being damaged, he said. Cont'd...
European offshore wind industry smashes installation record
By Madeleine Cuff for Business Green: The offshore wind industry is set for a bumper 12 months, as the latest figures from the European Wind Energy Association (EWEA) reveal installations in the first half of this year hit record levels.
As several projects reached completion and larger, more powerful turbines were deployed, new installations hit 2,342.9MW, triple the grid-connected capacity added in the same period last year. The surge in new projects makes the first six months of 2015 more successful than any other full year on record, in terms of installed capacity.
Some 584 new offshore wind turbines have been connected to the European grid so far this year, while the average turbine size has risen from 3.5MW to 4.2MW as manufacturers continue to develop more powerful turbines capable of capturing greater amounts of wind energy, the report said. Total offshore wind capacity across Europe has now reached 10,393.6MW, it added. Cont'd...
Offshore wind power gets foothold in US with Rhode Island project
By Richard Valdmanis for Reuters: Rhode Island's Deepwater Wind began installing the foundations for North America's first offshore wind farm on Monday, a milestone the company says could pave the way for an industry long established in Europe but still struggling with opposition in the United States.
The 30-megawatt wind farm, which will include five turbines located three miles (4.8 km) off the coast of the bucolic summer tourist destination of Block Island, will take more than a year to build and is scheduled to produce electricity for the tiny island community and the mainland by the end of next year.
"Our belief is once Block Island is up and running, it will bring offshore wind from theory to reality in the United States and open up opportunities to build larger projects," said Jeffrey Grybowski, Deepwater Wind's CEO. Cont'd...
The Nature Conservancy Installs Bird Safe Wind Power
The Nature Conservancy has completed its first phase of installation of SheerWind's INVELOX funnel-based wind power technology. Because Palmyra is home to a national wildlife refuge and more than a million nesting seabirds, conventional wind turbines were not an option due to the risk of bird strikes. What's more, the low wind speeds on the island would provide little to no energy production with traditional turbines.
The Conservancy turned to the Minnesota firm SheerWind to design the system resembling an hourglass turned on its side. Extending 83 feet horizontally with a big wind scoop at one end, an exhaust on the other, a Venturi section in the middle increases wind speed potentially three to six times. Nets over the intake and enclosed blades keep it bird friendly. The first phase of the installation includes a single turbine inside the Venturi, allowing for two additional to be installed in the near future.
The first phase of the INVELOX project is successfully charging batteries at night and on cloudy days to supplement the photovoltaic system also installed on Palmyra.
Acquisition announced for solar power supplier Vivint Solar
On July 20, SunEdison, the world's biggest renewable energy development firm, along with TerraForm Power, an owner and operator of clean energy power plants, announced the acquisition of Vivint Solar, a major supplier of residential solar systems in the U.S.
The merger will be worth approximately $2.2 billion in cash as the two major solar companies acquire the residential solar firm. Additionally, SunEdison has agreed to enter a power purchase agreement with TerraForm Power. Roughly 523 megawatts of solar power will be installed by Vivint Solar by the end of 2015, which will now all be moved over to SunEdison.
Through the $922 million power agreement, TerraForm Power will install the solar panels for residential solar protections through a "10-year average levered cash-on-cash yield of 9.5 percent," the release stated. Also, TerraForm Power will obtain future small commercial solar and completed residential projects from SunEdison's Residential and Small Commercial business unit. Cont'd...
New Material to Increase Solar Cell Efficiency
A team of researchers has come up with a solar cell that produces fuel rather than electricity. A material called gallium phosphide enables the solar cell to produce clean fuel hydrogen gas from liquid water.
To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution; but it is very expensive.
So, researchers were streamlining their search to a semi-conductor material that is able to both convert sunlight into an electrical charge and split water.
The team found gallium phosphide (GaP), a compound of gallium and phosphide, useful in this respect.
GaP has good electrical properties but the drawback is that it cannot easily absorb light when it is a large flat surface as used in GaP solar cells, said the study thatappeared in Nature Communications.
The researchers overcame this by making a grid of very small GaP nanowires, measuring five hundred nanometres (a millionth of a millimetre) long and ninety nanometres thick.
"That makes these kinds of cells potentially a great deal cheaper," said lead author Erik Bakkers from Eindhoven University of Technology, the Netherlands. Cont'd...
Renewable energy boom will mean vastly cheaper electricity
By Lucas Mearian, ComputerWorld: Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity -- and solar power that's less expensive than what fossil fuel-based power plants can produce.
Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion.
That was consensus view from a several keynote speeches delivered at the Intersolar Conference in San Francisco this week.
Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, said that in sun-rich countries, the cost of solar power is already below 5 cents per kilowatt and it will continue to plummet as battery storage systems become more prolific and less expensive. Cont'd...
South getting its first wind farm soon as bigger turbines make the region viable
By JASON DEAREN, Associated Press: On a vast tract of old North Carolina farmland, crews are getting ready to build something the South has never seen: a commercial-scale wind energy farm.
The $600 million project by Spanish developer Iberdrola Renewables LLC will put 102 turbines on 22,000 acres near the coastal community of Elizabeth City, with plans to add about 50 more. Once up and running, it could generate about 204 megawatts, or enough electricity to power about 60,000 homes.
It would be the first large onshore wind farm in a region with light, fluctuating winds that has long been a dead zone for wind power.
After a years-long regulatory process that once looked to have doomed the plan, Iberdrola spokesman Paul Copleman told The Associated Press that construction is to begin in about a month.
Right now, there's not a spark of electricity generated from wind in nine states across the Southeast from Arkansas to Florida, according to data from the American Wind Energy Association, an industry trade group.
But taller towers and bigger turbines are unlocking new potential in the South, according to the U.S. Department of Energy, and the industry is already looking to invest. Cont'd...
Obama Plan Would Give Poor Easier Access to Solar Energy
The Obama administration on Tuesday announced an initiative to help low- and middle-income Americans gain access to solar energy, part of a series of steps President Obama is taking to tackle climate change, according to administration officials.
The administration said it intends to triple the capacity of solar and other renewable energy systems it installs in federally subsidized housing by 2020, make it easier for homeowners to borrow money for solar improvements and start a nationwide program to help renters gain access to solar energy, the officials said.
The actions were announced in Baltimore by Brian Deese, Mr. Obama’s senior adviser for climate issues, and Representative Elijah E. Cummings, the Democrat who represents the city.
Mr. Deese, in a conference call with reporters, called the moves “part of a bigger-picture effort to try to drive innovation” toward cleaner, low-carbon energy solutions.
Also unveiled on Tuesday were commitments totaling more than $520 million from charities, investors, states and cities to pay for solar and energy-efficiency projects for lower-income communities. Cont'd...
Start of test with solar energy generating noise barriers alongside highway
Alongside the A2 highway near Den Bosch, The Netherlands, two test noise barriers are installed that generate solar energy. The aim of this practical test, that was officially launched 18 June is to assess the economic and technical feasibility of this form of energy generating noise barriers. Playing a key role in the test are the LSC panels, developed by researcher Michael Debije at TU/e.
The translucent, colored panels are a new type of energy source, developed jointly by TU/e. These 'luminescent solar concentrators' (LSCs) receive sun light and guide it to the side of the panels. There, it lands in concentrated form on traditional solar cells. "Thanks to their many colors the LSC are visually very attractive, which makes them ideal for use in many different situations in the built environment", explains Debije of the Department of Chemical Engineering and Chemistry, who has carried out years of research into these panels. "Further benefits are that the principle used is low cost, they can be produced in any desired, regular color, is robust, and the LSCs will even work when the sky is cloudy. That means it offers tremendous potential." Debije published his latest research findings on this subject last March in Nature.
On 18 June a one-year practical test started in 's-Hertogenbosch, led by the building company Heijmans. The researchers intend to assess the feasibility of generating electricity using solar cells integrated in noise barriers or SONOBs (Solar Noise Barriers). Cont'd...
Investment In Renewable Energy Yields More Jobs Than Fossil Fuel Sector
Joshua S Hill for CleanTechnica: A new report has determined that investments in energy-efficient and renewable energy sources yield more jobs for a set amount of spending than investing in maintaining or expanding the fossil fuel industry.
[wind turbine cowboy jobs] The report, Global Green Growth: Clean Energy Industrial Investment and Expanding Job Opportunities, was published earlier this week and presented at the Vienna Energy Forum 2015 by its two authors, the Global Green Growth Institute (GGGI) and the United Nations Industrial Development Organization (UNIDO).
“Significant progress has already been made in overcoming the hitherto conventional wisdom that taking steps to cut GHGs is incompatible with economic growth,” said Yvo de Boer, Director-General of GGGI. “This report moves the debate another positive step forward by showing that employment and development result from sustainable, green growth.”

Vecoplan - Planning and implementation of complete processing plants in refuse derived fuel production
In order to reduce the costs involved in the energy-intensive production of cement, many manufacturers are turning to refuse-derived fuels (RDF), considerably reducing the proportion of expensive primary fuels they would normally use. Solid fuels are being increasingly used - these might be used tyres, waste wood or mixtures of plastics, paper, composite materials and textiles. Vecoplan provides operators of cement plants with proven and robust components for conveying the material and separating iron and impurities, efficient receiving stations, storage systems and, of course, efficient shredders for an output in various qualities.
