Chernobyl is to become the world's largest solar power plant
ALEXANDRU MICU for ZME Science: The Ukranian government plans to turn Chernobyl, the site of the world’s most famous nuclear meltdown, into a sprawling solar power plant — the largest in the world.
Since the meltdown on April 26, 1986, no one’s been able to find any good uses for Chernobyl. A 1,600 square mile area was drenched in radiation and deemed an “exclusion zone,” so everyone was evacuated after the clean-up efforts were concluded and the plant was sealed in its ubiquitous sarcophagus. The buildings, goods, and infrastructure in the area were abandoned so fast that the city looks like time froze there 30 years ago — albeit with a Falloutesque look. Since we left, nature took over, and for the most part, is thriving in our absence (though the microbes that decompose dead organic matter seem to be having a hard time living here.)
In a recent interview, however, Ukraine’s ecology minister Ostap Semerak said that the government is negotiating with two US investment firms and four Canadian energy companies to develop Chernobyl’s solar potential. The area is uniquely suited for the purpose — the land is extremely cheap, much of the required infrastructure, such as roads are already built. Even better, the power lines that served the old 4GW reactor are still useable. Cont'd...
Tesla Lowers Bid, Agrees to Pay $2.6 Billion for SolarCity
Chris Martin for Bloomberg Technology: Elon Musk’s Tesla Motors Inc. reached an agreement to buy SolarCity Corp. for $2.6 billion, about $300 million less than an initial proposal criticized as a “bailout” for the solar company in which he’s the largest shareholder.
SolarCity investors will receive $25.37 a share in stock under the agreement, according to a statement Monday. Musk initially offered $26.50 to $28.50 a share in Tesla stock. Analysts have said in the past that the bid was too low and investors have questioned the wisdom of Musk combining his electric-car maker with the clean-energy company. The deal, which allows SolarCity to solicit competing takeover offers through Sept. 14, will now go to the shareholders of the companies for approval. Cont'd...
Molten storage and thermophotovoltaics offer new solar power pathway
Georgia Institute of Technology: New computer modeling suggests that high temperature TPV conversion -- which captures infrared radiation from very hot surfaces -- could one day rival combined-cycle turbine systems when combined with thermal storage using liquid metal at temperatures around 1,300 degrees Celsius. Advances in high-temperature components and improved system modeling, combined with the potential for conversion costs an order of magnitude lower than those of turbines, suggest that TPV could offer a pathway for efficiently storing and producing electrical power from solar thermal sources, a new study suggests.
The underlying technologies of high temperature storage and thermophotovoltaic conversion could also be used to produce grid-scale batteries able to rapidly supplement other power sources by storing heat for quick conversion to electricity. The research, supported by ARPA-E, was reported July 4 in the journal Energy and Environmental Science by researchers at the Georgia Institute of Technology. Cont'd...
Belgian scientists make novel water-from-urine machine
Reuters: A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries.
While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid.
"We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese.
The urine is collected in a big tank, heated in a solar-powered boiler before passing through the membrane where the water is recovered and nutrients such as potassium, nitrogen and phosphorus are separated. Cont'd...
Turbines for First U.S. Offshore Wind Farm
The Maritime Executive: Preparations for the groundbreaking Block Island Wind Farm – America's first – are well under way, with the regulatory permits obtained, the funding procured and the jacket installation complete. Now the actual equipment for the farm, towers, blades and five massive turbines have been shipped, ready for assembly.
The blades arrrived in Providence, RI from Denmark on the general cargo shipSuomigracht late last month, and the turbines are on board the Fred Olsen jackup construction vessel Brave Tern, currently under way across the North Atlantic. When theTern arrives, it will begin the process of installing the towers; that work is expected to begin in August.
The 20-mile cable connecting Block Island with the mainland was completed on June 28 – providing the island with its first electrical and fiber optic connection ever. Deepwater Wind, the developer and operator of the farm, has completed a separate cable linking the facility with Block Island, and expects to finish cable linkages between the five wind towers this month.

Why flying a kite could be the future of clean energy
Antony Michels for Yahoo Finance: David Schaefer wants to sell $50,000 kites to farmers to help them generate electricity by harnessing the power of the wind.
Schaefer, 54, is the CEO of eWind Solutions, a Beaverton, Oregon, company he founded in 2013 after quitting his job as director of mechanical engineering at Xerox.
“Imagine when you were a kid in a field flying the kite,” Schaefer says. “When the wind picks up you remember feeling that pull on the string. Well that pull is really energy. That’s what we’re doing. We’re harnessing that energy.” Cont'd...
Obama makes new push on solar power
Timothy Cama for The Hill: The Obama administration is making a new large-scale effort to encourage deployment and use of rooftop solar power on homes.
Numerous agencies announced new or strengthened coordinated efforts Tuesday aimed at increasing solar installations in houses owned by low- and moderate-income Americans, including a new goal for solar installations and a policy change to increase access to a key financing mechanism for solar power and energy efficiency.
“This is an approach that cuts across the government to try to take advantage of the fact that the cost of renewable technologies has come down dramatically during President Obama’s tenure, and we want to advantage of that a try to encourage more homeowners to actually benefit directly from that dynamic,” Brian Deese, a top adviser to Obama, told reporters.
The administration is dubbing the effort the “Clean Energy for All Americans Initiative.” Cont'd...
Why Drones Are 'Game-Changing' for Renewable Energy
Julia Pyper for GreenTechMedia: Amazon caused quite the stir in 2013 when it announced plans to launch a drone delivery service. People were both thrilled and horrified at the thought of flying robots delivering toilet paper to our doorsteps.
Some drone enthusiasts hoped to see Amazon launch a drone-based solar installation service -- but alas, that business doesn't exist. Yet.
Drones are already disrupting the solar sector, however.
This week at Intersolar North America, DroneDeploy, a cloud software platform provider for commercial drones, and DJI, a leading maker of drones and camera technology, announced a partnership that is expected to dramatically increase the efficiency of solar panel installation and inspection using drone-based thermal imagery capture and analytics.
The companies claim that customers can reduce residential solar system measurement times by up to 50 percent and reduce commercial measurement times from days to minutes. In addition, on-board thermal imagery can help to ensure that equipment is in the optimal position for maximum production. Cont'd...
Energy Storage Would Get U.S. Tax Credits in Bipartisan Bill
Chris Martin for Bloomberg Politics:  Energy storage would gain access to the same tax incentives that helped make renewable energy the biggest new source of electricity in the U.S. last year under a bill introduced in the Senate.
Batteries like the lithium-ion ones in phones and electric vehicles would be eligible for the tax incentives when connected to the utility grid at homes and businesses under a bill introduced Tuesday by Democratic Senator Martin Heinrich from New Mexico. The bill has eight co-sponsors including Dean Heller, a Nevada Republican, according to a statement.
Other energy storage technologies such as pumped hydroelectric power, flywheels and compressed air would also have access to the tax credits, modeled after incentives for the solar industry, which reimburse as much as 30 percent of installation costs. Â Cont'd...

Why Every Rooftop Solar System Needs Energy Storage
John Petersen for Investor Intel: Rooftop solar is an odd duck. A consumer buys an expensive capital asset with the expectation that he’ll recover his investment through lower electric bills. As a matter of metaphysics, he’s decided to go into the power business with the primary goal of satisfying the most important and discriminating customer on the planet. The value proposition he currently offers his local electric utility is:
I’ll buy less electricity from you because of my solar panels, but I need you on standby 24/7 to supply my nighttime needs and fill any weather related power production gaps;
Since my solar panels will frequently produce more power than I need, I want you to give me credit for any excess power production, let me draw equivalent power from you when I need it, and structure it all as a tax free swap;
You can, of course, bill me for any difference between what I deliver and what I take;
I’ll have no duty to buy a fixed amount of power from you or deliver a fixed amount of power to you, but you must supply whatever I need and take whatever I don’t need; and
You will be required to pay all of the costs associated with weather related production gaps and pass those costs through to your other customers.

Scripps Vessel Proves Viability of Renewable Fuel on 14,400-Mile Voyage
Chris Jennewein for Times of San Diego: A Scripps Institution of Oceanography research vessel has demonstrated the viability of renewable fuel by traveling 14,400 nautical miles over a 16-month period on renewable diesel.
The R/V Robert Gordon Sproul used a hydrogenation-derived renewable fuel called NEXBTL Renewable Diesel developed by Neste Oil in Finland. The experiment began in September 2014 and ran through December 2015, during which time the vessel used a total of 52,500 gallons.
“Part of the Scripps mission is to protect the environment, and one of the most significant changes that we could make in our ship operations involved moving toward the use of cleaner, renewable fuels,” said Scripps Associate Director Bruce Appelgate. “As scientists, we know we need to develop sustainable means of powering our ships to address pollution concerns as well as to mitigate future increases in fossil fuel costs.”
Renewable biofuel is nearly carbon-neutral and produces cleaner emissions, thus decreasing greenhouse gas emissions and improving air quality relative to fuels derived from petroleum. Cont'd...
SolarCity pushing industry to 40% increase in useful lifetime of solar power installations
John Fitzgerald Weaver for Electrek: In a new report released by SolarCity, we are seeing that solar power systems have a usable lifetime of at least 35 years – 40% longer than the market expects. The key finding of the report is that power degradation (annual efficiency loss) of solar panels supplied to SolarCity is as much as 35% lower than for a comparable industry-wide selection of non-SolarCity panels, which are typically expected to last for 25 years. SolarCity feels it is the implementation of a stringent and industry-leading “Total Quality Program” that has driven this.
SolarCity is in the unique position of being one of the largest deployers of solar panels – from multiple manufacturers – in the world, and with their tens of thousands of systems connected to a central database they know realtime performance. In the study here, SolarCity looked at greater than 11,000 panels to determine their data points and come to their conclusion that their solar panels are performing well beyond expected industry standards.

Here's How Brexit May End Most British Wind Power
Andrew Follett for the Daily Caller: Officials from Britain’s wind industry are terrified their subsidies and tax incentives will end because of the U.K.’s decision to leave the European Union, according to a report by Reuters published Friday.
The report found that British wind companies, particularly ones that specialize in offshore wind power, are worried that Brexit places the government subsidies and easy access to financing at risk. The industry is deeply dependent on these subsidies to make projects more economically viable. Britain’s political uncertainty following the pending resignation of Prime Minister David Cameron means cuts to subsidies are likely. The Brexit could also make it much harder for wind companies to get loans from European banks, which could significantly slow the expansion of wind power. Cont'd...
Tesla applies for 6 new trademarks to sell solar energy under the 'Tesla' brand
Fred Lambert for Electrek: Last week, Elon Musk announced his plan for Tesla to acquire SolarCity and fold the solar installer’s operations into Tesla’s own business. The offer is still contingent on board approval and shareholder votes at both companies, but Electrek has now learned that the automaker is going ahead with trademark applications to sell solar products under its ‘Tesla’ brand.
According to trademark filings obtained by Electrek, Tesla’s trademark and copyright attorney at Cooley LLP, Ariana Hiscott, filled 6 new trademark applications for the company on June 22nd – the day Tesla announced the offer.
The trademarks applications range from solar cells and solar modules: “Solar energy equipment, namely, photo-voltaic solar modules for converting electronic radiation to electrical energy; and equipment for use in collecting and converting solar into electricity, namely, solar cells and inverters.”
To the installation and repair of solar panels: “Installation, maintenance and repair of solar panels and other equipment for use in converting solar energy into electricity; installation of solar energy systems and consulting related thereto.”
It also covers the monitoring of solar energy generation and the financing of solar installations. All applications are for the trademark “Tesla”. Cont'd...
