Stabilizing battery storage

Morgan Sherburne for U of Michigan News:  An issue that has long plagued renewable energy facilities is how to efficiently store energy collected from sun or wind. Now, University of Michigan and University of Utah chemists have developed an energy-storing molecule that is 1,000 times more stable than current compounds, potentially leading to a longer-lived, more efficient battery. The researchers are working to develop industrial-scale batteries that can store large amounts of energy for deployment when the sun sets or the wind stops blowing. Deep-cycle lead batteries or lithium ion batteries are already on the market, but each type presents challenges, including the significant environmental hazards of disposal. Also, these kinds of batteries wear out relatively quickly.   Cont'd...

How drones are helping design the solar power plants of the future

Katie Fehrenbacher for T he Guardian:   At the edge of a plot of muddy farmland, a few miles down the road from the University of California at Davis, an engineer takes a few quick steps across crop rows and lets go of a three-foot drone. Within seconds, the device - which weighs less than 2lbs and carries a powerful camera - ascends hundreds of feet into the cold, clear, blue sky and begins to snap detailed photos of the ground far below, including a long row of large solar panels mounted on steel poles. This flight is just a test, demonstrated by Kingsley Chen, the drone fleet coordinator for SunPower at the solar company's research and development center, which is under construction and about a two-hour drive northeast of the San Francisco Bay Area. The drone will enable SunPower to survey a wide region and help design a solar power farm that can fit more solar panels on a piece of land, more quickly and for lower costs than it previously could.  Con'td...

SDG&E Unveils World's Largest Lithium Ion Battery Energy Storage Facility

In response, SDG&E expedited ongoing negotiations and contracted with AES Energy Storage to build two projects for a total of 37.5 MW of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was built in El Cajon.   Full Press Release:  

Follow the Patents: For Solar Power, the Devil Is in the Details

Alec Schibanoff for Electric Light & Power:  There actually is a crystal ball that permits you to see into the future. All you have to do is follow the patents. The latest patents in any technology will show you where that technology—and the businesses that use that technology—are going. This month, we take a look at the future of solar panel installation. The first solar power generator was displayed at the Universal Exposition in Paris in 1878. The first U.S. Patent for a solar power device was awarded the next year to Edward Weston. He actually received two patents: U.S. Patent No. 389,124 for an “Apparatus for Generating Solar Radiant Energy” and U.S. Patent No. 389,125 for the “Art of Utilizing Solar Radiant Energy.” It was not until 1954 that Bell Labs developed the first silicone-based solar panel.   Cont'd...

California demand for wind power energizes transmission firms

Nichola Groom for Reuters:  A firm controlled by Philip Anschutz, the billionaire entertainment and pro sports magnate, will soon build the largest wind farm in the United States to serve utilities in California, where officials have set ambitious green power goals. The $5 billion project, however, will be constructed 700 miles away in Wyoming, a state better known for coal mines and oil fields. The vast distance between the two states provides a different Anschutz-owned firm with another big opportunity: a $3 billion project building transmission lines to deliver the power - one of a dozen similar power-line projects by other companies across the West. (Map: How wind power will get from Wyoming to California click here) In all, about 5,700 miles of transmission lines are in development with the goal of delivering renewable energy to California from other states, according to the Western Interstate Energy Board.   Cont'd...

High-tech canopy helps generate solar power while providing shade

Barbara Eldredge for Curbed:  Imaginative architect and designer Carlo Ratti has had some bonkers ideas over the past year, including an exercise-powered gym barge and a mile-high skyscraper park. But his latest project is on the sunnier side of feasibility. Literally. The Sun&Shade is a light-reflecting canopy made of mirrors that automatically rotate to catch the sun’s rays and fling them at a photovoltaic panel, “located a safe distance away.” This generates clean electricity up top while cooling the shaded area beneath. A working prototype of the mirrored structure just debuted at Dubai’s Museum of the Future as part of its “Reimagining Climate Change.”   Cont'd...

Patton for Sacramento Business Journal:  A solar module factory expected to bring more than 200 jobs to Sacramento is slated to begin production in mid-September at McClellan Business Park.  It will be the first U.S. factory for Nanjing, China-based solar cell and module manufacturer China Sunergy Co, who on Thursday announced its subsidiary Sunergy America has agreed to lease a 140,000-square-foot manufacturing building — previously a plant where J.C. Penney made window coverings. Simon Szeto, a Sunergy advisor, said the company will bring around 20 management staff from overseas and will hire other employees locally.  The work being done at the factory will include putting together the modules. Each module includes a solar cell, an aluminum frame, tempered glass, cables and a junction box. The completed products, which can be placed on a ground mount or rooftop, will be sold commercially in the U.S, Szeto said.  Cont'd...

Scientists invented a battery that could work for a decade without degrading

Mike Wehner for BGR:  Energy storage degradation in rechargeable batteries is a pretty serious problem that many of us put up with on a regular basis. It’s why your iPhone seems to last forever when it’s brand new out of the box but seems like it dies by lunchtime after a couple of years of use. Now, researchers at Harvard have developed a new battery technology using a bit of chemistry magic to create a rechargeable power source that could be tapped for many years with very little in the way of maintenance.

Kipp & Zonen - DustIQ the novel soiling monitoring solution for solar panels

Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
