World's first solar panel road opens in Normandy village

Kim Willsher for The Guardian:  France has opened what it claims to be the world’s first solar panel road, in a Normandy village. A 1km (0.6-mile) route in the small village of Tourouvre-au-Perche covered with 2,800 sq m of electricity-generating panels, was inaugurated on Thursday by the ecology minister, Ségolène Royal. It cost €5m (£4.2m) to construct and will be used by about 2,000 motorists a day during a two-year test period to establish if it can generate enough energy to power street lighting in the village of 3,400 residents. In 2014, a solar-powered cycle path opened in Krommenie in the Netherlands and, despite teething problems, has generated 3,000kWh of energy – enough to power an average family home for a year. The cost of building the cycle path, however, could have paid for 520,000kWh.   Cont'd...

U.S. wind power enjoys a rebirth as solar's obstacles mount

Nichola Groom for Reuters:  A year after Congress extended generous tax credits for renewable energy projects, the U.S. wind industry is thriving. Solar power companies, meanwhile, are hunkering down for a rough 2017. The tax credit renewal has boosted the long-term outlooks for both industries. But in the short term, the subsidies are far more attractive for wind power, which has spurred utilities to launch wind projects while they scale back or delay solar installations. Advances in wind turbine technology are also opening up new locations for development and driving a wave of spending to upgrade existing projects. In the last few weeks, power companies with large renewable holdings - including Southern Co, NextEra Energy Inc and Xcel Energy Inc - have announced plans to invest billions of dollars in wind. "We're making a pivot now away from solar," Southern Chief Executive Tom Fanning told a meeting with Wall Street analysts in October.   Cont'd...

The Solar Industry Has Paid Off Its Carbon Debts

Robinson Meyer for The Atlantic:  Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world. Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all?  To that concern, a new analysis answers: Yes. The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds.   Cont'd...

Nearly half of residential distributed solar power is owned by private companies

Lucas Mearian for ComputerWorld:  About 44% of all solar power that's installed on residential rooftops, known as distributed solar capacity, is owned by private businesses, such as SolarCity or Vivint Solar, according to new government data. Distributed solar capacity in the U.S., which includes all solar power capacity other than utility-scale installations 1 megawatts (MW) or larger,  increased to 12.3 gigawatts (GW) as of September, according to new figures from the Energy Information Administration (EIA). In comparison, a cumulative 11.6GW had been installed in the U.S. by the end of 2015.   Cont'd...

Glow-in-the-dark dye could fuel liquid-based batteries

Charlotte Hsu for University of Buffalo:  BUFFALO, N.Y. — Could a glow-in-the-dark dye be the next advancement in energy storage technology?  Scientists at the University at Buffalo think so. They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes.  BODIPY — short for boron-dipyrromethene — shines brightly in the dark under a black light. But the traits that facilitate energy storage are less visible. According to new research, the dye has unusual chemical properties that enable it to excel at two key tasks: storing electrons and participating in electron transfer. Batteries must perform these functions to save and deliver energy, and BODIPY is very good at them.  In experiments, a BODIPY-based test battery operated efficiently and with longevity, running well after researchers drained and recharged it 100 times.   Cont'd...

DOE energy innovation hub backs two key future battery technologies

Nick Flaherty for EE Times:  After four years of evaluation, the Joint Center for Energy Storage Research (Chicago, IL) is backing two key technologies for the future of battery systems. The Center was set up four years ago with a five year remit to explore new battery technology for transportation and the electricity grid that, when scaled to commercial production, are capable of delivering five times the energy density at one-fifth the cost of commercial batteries available in 2011. The Center has investigated 1,500 compounds for electrodes and 21,000 organic molecules relevant for liquid electrolytes as well as filing 52 invention disclosures and 27 patent applications, says director George Crabtree. Five techno-economic models created by JCESR for designing virtual batteries on the computer are being used to evaluate the best pathways for beyond-lithium-ion systems to reach 400 watt hours per kilogram (400 Wh/kg) and $100 per kilowatt hour ($100/kWh).  Cont'd...

The World's Largest Solar Plant Is Now Online in India

Avery Thompson for Popular Mechanics:  The world's largest solar power plant has just been completed in Kamuthi, in Tamil Nadu, India. The new plant adds 648 MW to the country's generating capacity. The Kamuthi Solar Power Project takes the title of world's largest solar plant from the Topaz Solar Farm in California, which was completed two years ago and has a capacity of 550 MW. The Kamuthi Solar Power Project was built in only 8 months, and cost $679 million to complete. It contains 2.5 million individual solar panels, covers an area of almost 4 square miles, and is expected to power 150,000 homes.   Cont'd...

Could depleted oil wells be the next step in energy storage?

Power-Technology.com - Quidnet Energy is hoping to revolutionise energy storage with its underground pumped hydro concept, which uses abandoned oil and gas wells to store and release pressurised water, driving turbines and feeding electricity back into the grid. How does the concept work and how far could it go? Quidnet co-founder Aaron Mandell explains. As the cost of renewable energy continues to decline and intermittent clean power sources such as wind and solar gain ever an ever larger foothold in the global energy mix, the ability to store energy that can be quickly dispatched when needed has become as important as the development of renewables themselves. Robust storage options could allow for greater integration of intermittent renewables, as they facilitate flexible capacity-building that relies far less on coal and gas-fired plants for baseload generation, meaning energy storage is a key step in the journey to wean the world off its fossil fuel addiction.   Full Interview:

The First Tidal Generator in North America Is Now Online

Avery Thompson for Popular Mechanics:  The first tidal generator in North America has gone online this month in the Bay of Fundy, and is expected to generate enough electricity to power 500 homes. While most hydro generators harness the energy of falling water, or the energy of the waves, tidal power uses the energy of the high and low tides. At the Bay of Fundy in Nova Scotia, which has the largest tides in the world, that energy is being harnessed to generate 2 megawatts of electrical power. In the Bay of Fundy, the difference between high and low tide is about 56 feet. Approximately 115 billion tons of water flow in and out of the bay every tidal period. Two renewable energy developers, OpenHydro and Emera, decided to build turbines on the seafloor that could harness that power.   Cont'd...

Solar Power Turns Water and Carbon Dioxide Into Fuel

Seeker:  Finish researchers are building a demonstration power plant that would use solar-generated electricity, water and carbon dioxide extracted from the atmosphere to create gas and liquid fuels. The Lappeenranta University of Technology and VTT Technical Research Centre are working together on the SOLETAIR project, which is being built on the university campus and is scheduled for completion in 2017. Germany's Karlsruhe Institute of Technology also is a player in the project.  The project involves several different innovations. VTT will design equipment that will capture CO2 from the air and store it, while Lappeenranta researchers will build a device to produce hydrogen from water via electrolysis. Karlsruhe has developed a a microstructured, chemical reactor to convert the hydrogen produced from solar power together with carbon dioxide into liquid fuels, according to a press release. The reactor will be built by INERATEC, a spinoff company created by Karlsruhe.   Cont'd...

Solar power proponents hopeful Trump sees benefit of growing industry

Ivan Penn and Rob Nikolewski for The LA Times:  Longtime solar executive Barry Cinnamon got up Wednesday wondering what a Donald Trump administration will mean for his industry. “I woke up this morning and walked to my car and took a picture of the sun coming up, and it did indeed come up,” said Cinnamon, president of Cinnamon Solar, one of the highest-profile solar companies in Silicon Valley. Candidate Trump said a lot of things that heartened conventional oil and natural gas producers and worried the renewable energy business, which is growing fast but is still a tiny part of the energy landscape.   Cont'd...

Self-drive delivery van can be 'built in four hours'

Jane Wakefield for BBC News:  A self-drive electric delivery van, that could be on UK streets next year, has been unveiled at the Wired 2016 conference in London. The vehicle's stripped-back design and lightweight materials mean it can be assembled by one person in four hours, the firm behind it claims. The vehicles will be "autonomous-ready", for when self-drive legislation is in place, the firm said. The government wants to see self-drive cars on the roads by 2020. "We find trucks today totally unacceptable. Loud, polluting and unfriendly," said Denis Sverdlov, chief executive of Charge, the automotive technology firm behind the truck. "We are making trucks the way they should be - affordable, elegant, quiet, clean and safe."   Cont'd...

Is The Best Analogy For The Energy Storage Business--Eeek!--Hard Drives?

Michael Kanellos for Forbes:  The optimism in the energy storage industry is based on soaring demand, rapid technological advances, expanding capacity and, for some, what will likely be a scary competitive environment. First, the good news. Lithium ion battery packs over the last ten years have declined faster than the cost of solar, said John Carrington, CEO of Stem, which makes behind-the-meter storage systems for hotels and other commercial customers looking to shave peak power costs, during a hallway meeting at Finance West sponsored by the American Council of Renewable Energy this week. Solar panels have declined by 50% or more in the last five years. Batteries have declined by 80% in three years, he said. Battery packs hit the under $300 per kilowatt hour mark last December, Carrington added. By 2020, battery pack prices could drop to $190 per kilowatt hour. (In 2007, lithium ion battery packs in the wholesale markets sold for around $1,000 per kilowatt hour.)   Cont'd...

New York set for offshore wind after environmental review

Daniel J. Graeber fro UPI:  Areas off the New York coast will be open for offshore wind energy bidders, but some area is reserved because of ecological concerns, the U.S. government said. The U.S. Interior Department, in coordination with its Bureau of Ocean Energy Management, said it would open 79,350 acres off the coast of New York up for a commercial wind energy lease sale. About 1,780 acres was removed because of environmental concerns associated with a subsea feature known as the Cholera Bank. "In a comment letter, the National Marine Fisheries Service identified the Cholera Bank feature as a sensitive habitat to be avoided for the placement of structures," an Interior Department stated read. "As a result of this removal, the revised lease area will be approximately two percent smaller than the lease area considered in the proposed sale notice."   Cont'd...

Elon Musk wants to sell you a better-looking solar roof amid slowing growth for panels

Ivan Penn and Russ Mitchell for The LA Times:  Like some kind of 21st century Willy Wonka, audacious entrepreneur Elon Muskchose a prime spot on the Universal Studios Hollywood backlot tour to unveil his latest attempt to energize an industry — roofs that generate solar power but look like no other.  Musk, the chief executive of Tesla Motors and chairman of SolarCity, showcased a line of high-design solar roof tiles that would replace clunky solar panels and tie into an upgraded version of the Tesla wall-mounted battery for those times when the sun doesn’t shine. The glass solar shingles resemble French slate, Tuscan barrel tile or more conventional roofing materials with a textured or smooth surface.  “The key is to make solar look good,” Musk said during the product introduction staged on the old set of ABC’s “Desperate Housewives” series, where he had re-roofed four of the Wisteria Lane houses. “If this is done right, all roofs will have solar.”   Cont'd..
