Increasing the Storage Capacity of Lithium Batteries
BioSolar is developing electrode material technologies to increase the storage capacity, lower the cost and extend the life of lithium-ion batteries.
Why large-scale wind power is so hard to build
Michael McDonald, Oilprice.com via USA Today : he Bureau of Land Management faces a problem and wants to shake up the rules around wind farm approvals. The problem is straight-forward on its face, but difficult to reconcile logically: Why are so few new large-scale wind projects being built? Despite the fact that nearly everyone – environmentalists, government regulators, and business interests –wants to build more wind farms, precious few are making it over the goal line.
Since 2009, the Obama Administration has approved 46 wind farm projects that would cover a proposed 216,356 acres of public land. Yet only 15 of these 46 projects have made it into operation. The rest are stuck in limbo with years of mandatory environmental analysis ahead or have been cancelled outright. Cont'd...
Batteries Get a Boost From California Utilities
If we stop and take a critical look at the fragility of our energy supply system, we see that it could be strengthened by distributing energy generation and storage. This means its not just the utility companys job to store energy… its everyones job.

Transparent solar panels are 50 times more productive than regular photovoltaics
Luke Dormehl for DigitalTrends: As the term “regular windows” suggests, users don’t have to replace the existing windows in their home, but need only treat them with a special process developed by the company.
“We apply liquid coatings to glass and plastic surfaces at ambient pressure, and dry these coatings at low temperature to produce transparent films,” Conklin continued. “We repeat these processes, and then collectively these coatings — and thus the glass and plastic surfaces — generate electricity.”
Of these coatings, the most important is the so-called “Active Layer,” through which electricity is generated by the absorption of light, and the transparent conductors, which allow the electricity to be extracted. “[The] coatings are primarily organic, primarily from carbon, hydrogen, nitrogen, and oxygen,” Conklin said. “We are constantly refining each of the layers to improve on the power we’re able to extract from these coatings and enhance their manufacturability.” Cont'd...
Solar cell is more efficient, costs less than its counterparts
Massachusetts Institute of Technology via Science Daily: A team of researchers from MIT and the Masdar Institute of Science and Technology may have found a way around this seemingly intractable tradeoff between efficiency and cost. The team has developed a new solar cell that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun's energy. The researchers call the device a "step cell," because the two layers are arranged in a stepwise fashion, with the lower layer jutting out beneath the upper layer, in order to expose both layers to incoming sunlight. Such layered, or "multijunction," solar cells are typically expensive to manufacture, but the researchers also used a novel, low-cost manufacturing process for their step cell.
The team's step-cell concept can reach theoretical efficiencies above 40 percent and estimated practical efficiencies of 35 percent, prompting the team's principal investigators -- Masdar Institute's Ammar Nayfeh, associate professor of electrical engineering and computer science, and MIT's Eugene Fitzgerald, the Merton C. Flemings-SMA Professor of Materials Science and Engineering -- to plan a startup company to commercialize the promising solar cell. Cont'd...
NREL Research Puts the Wind at an Industry's Back
NREL's ultimate goal in this testing is to foster the technological developments necessary for wider deployment of wind energy in the marketplace at the lowest cost possible.
Making waves: Shetland tidal power breakthrough is another world first for Scotland
Martin Hannan for The National: HOUSEHOLDERS on the Shetland Isles were not aware of it, but when they plugged in their kettles recently, they were sharing in a bit of history.
For the Shetland Tidal Array at Bluemull Sound, installed by Nova Innovation of Edinburgh, has become the world’s first tidal power array to be connected to a grid and deliver power on a commercial basis – to dozens of homes on the islands.
The achievement has been hailed by environmentalists and the renewable industry as a turning point in the development of marine power.
Nova had shown its technology could work with a single turbine which generated electricity in March. But the installation of second turbine that is also working to the grid proves that large tidal power arrays can and do work. Commercially viable tidal power is seen as something of a Holy Grail by the industry, since it is one of the few renewable energy sources that is entirely predictable – as one industry source once put it: “there will be tidal power available as long as the moon is in the sky”.

Indian Scientists Design Solar Tree to Save Space for Solar Power Generation
Anjana Pasricha for VOA News: Indian scientists have designed a “solar tree” that they hope will help overcome one of the key challenges the country faces in the generation of solar power.
With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks.
“It takes about four-square meters of space to produce energy which otherwise would have required 400 square meters of space. So almost 100 times the space is saved, which as you know is very valuable,” said Daljit Singh Bedi, chief scientist at the Council of Scientific and Industrial Research (CSIR) in New Delhi, whose laboratory in Kolkata developed the tree.
A scarce resource in India, acquisition of land to develop roads, factories and other infrastructure is a sensitive issue that has led to frequent and sometimes violent protests from displaced people. Cont'd...
San Bernardino County rejects a controversial solar power plant proposed for the Mojave Desert
Louis Sahagun for The LA Times: The San Bernardino County Board of Supervisors has rejected a controversial solar plant proposed for the Mojave Desert’s Soda Mountains, citing concerns that the project would destroy habitat and block ancient trails used by bighorn sheep for thousands of years.
In a 3-2 vote, the board on Tuesday declined to certify documents required under state law in order to issue county permits for the project on public land along Interstate 15 near the entrances to Joshua Tree National Park and Death Valley National Park, and less than a mile from the Mojave National Preserve.
“We endorse renewable energy, but this was the wrong project in the wrong location,” said Supervisor Robert A. Lovingood. Cont'd...

'Ideal' energy storage material for electric vehicles developed
Walt Mills for Phys.org: The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State materials scientists. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. Their results are published today (Aug. 22) in the Proceedings of the National Academy of Sciences (PNAS).
"Polymers are ideal for energy storage for transportation due to their light weight, scalability and high dielectric strength," says Qing Wang, professor of materials science and engineering and the team leader. "However, the existing commercial polymer used in hybrid and electric vehicles, called BOPP, cannot stand up to the high operating temperatures without considerable additional cooling equipment. This adds to the weight and expense of the vehicles." Cont'd...
