US team’s battery ‘breakthrough’

See on Scoop.itGreen Energy Technologies & Development

Researchers believe they have found a way to radically shrink the size of batteries while offering the same amount of power and faster recharges than at present.

Duane Tilden‘s insight:

>The scientists’ “breakthrough” involved finding a new way to integrate the anode and cathode at the microscale.

“The battery electrodes have small intertwined fingers that reach into each other,” project leader Prof William King told the BBC.

“That does a couple of things. It allows us to make the battery have a very high surface area even though the overall battery volume is extremely small.

A cross-section of the battery reveals the 3D-design of the research project’s anodes and cathodes

“And it gets the two halves of the battery very close together so the ions and electrons do not have far to flow.

“Because we’ve reduced the flowing distance of the ions and electrons we can get the energy out much faster.”<

Power plant cancellations: Green Energy Act looms behind gas plant mess | Toronto Star

See on Scoop.itGreen & Sustainable News

The Green Energy Act stripped Ontarians of their right to appeal decisions on locating energy facilities.

Duane Tilden‘s insight:

>Former premier Dalton McGuinty told a legislative committee this week that “there was a faulty selection process for gas plant sites and they were wrongly located and had to be shut down.”

But that faulty process was the result of his much-ballyhooed Green Energy Act. And the cost of the faulty process and the subsequent shutdown of the Oakville and Mississauga sites will be $585 million or more.

[…]

The result is that Ontario electricity rates, at one time among the lowest in North America, are now some of the highest. Ontario residential customers are paying about three times more for electricity than they did when McGuinty took office. Ontario industry, which used to benefit from low electricity costs, is suffering.<

New Study: Distributed Solar Energy Provides $34 Million in Benefits to Arizona Ratepayers | SEIA

See on Scoop.itGreen & Sustainable News

WASHINGTON, DC – A study released today shows that distributed solar generation (DG) and net energy metering will provide Arizona Public Service (APS) customers with $34 million in annual benefits.

Duane Tilden‘s insight:

>The study found that for each dollar of cost, DG provides $1.54 worth of benefits to APS customers. The net benefits for APS customers will amount to $34 million per year beginning in 2015. Benefits include savings on expensive and polluting conventional power and power plants; reduced investments in transmission and distribution infrastructure; reduced electricity lost during transportation over power lines, as distributed solar power is generated and consumer locally; and savings on the cost of meeting renewable energy requirements.

“This study clearly shows that solar offers concrete net benefits to all APS ratepayers, regardless of whether or not they have installed solar” said Carrie Cullen Hitt, senior vice president of state affairs at the Solar Energy Industries Association (SEIA). “It’s essential that we keep smart policies like net metering in place so that Arizona can continue to benefit from its abundant solar resources.”<

Transactive, distributed energy markets hold promise | Intelligent Utility

See on Scoop.itGreen Energy Technologies & Development

Transactive energy markets hold the promise to achieve economic efficiency and reliability across the bulk power system and distribution networks.  This research area was identified in the Caltech Resnick Sustainability Institute’s Grid2020 report released last fall, and was the topic of the third discussion of the series in April 2013.

Duane Tilden‘s insight:

>Significant untapped potential exists to leverage a new class of flexible mixed distributed assets (e.g., distributed generation, responsive demand, storage, power electronics and electric vehicles), what has been called DR 2.0, to manage the power system. But, this requires changes in both market designs and grid operations.  […]

Current wholesale market rules are significant barriers to participation as they effectively do not distinguish a 500 MW power plant from a 5kW electric vehicle battery. This is very unfortunate, as the technology to tap these smaller resources and create significant value for customers is available today. Heather Sanders, Director, DER Policy at CAISO shared that, “a challenge is to create market participation rules that meet operators’ needs for reliability, but also facilitate customer value opportunities.” <

Highview Power Storage, an award-winning UK developer of utility scale liquid air energy storage technologies, has had two multi-MW projects successfully put through to the feasibility stage of DECC’s Energy Storage Technology Demonstration…

See on www.gasworld.com

>Project one involves the National Grid, Costain and Highview, for a proposed utility-scale demonstration project of a fully integrated liquid air energy storage plant of up to 6MW output, hosted by National Grid’s Grain Liquefied Natural Gas (LNG) site at the Isle of Grain in Kent.

The plant would have around five hours of operation (30MWhs), making it the largest demonstration of new energy storage technology in the UK.<

Fluorescent Dye Boosts Solar Cell Efficiency by a Whopping 38 Percent

See on Scoop.itGreen Energy Technologies & Development

Squaraine dye helps to improve light absorption, recycle electron and enhance the light to energy conversion in solar cells, increasing efficiency by a whopping 38 percent.

Duane Tilden‘s insight:

>The Yale researchers relied on Förster resonance energy transfer (FRET), a well-known biochemical mechanism, to achieve this radical new energy conversion rate.

“In this type of solar cell—FRET-based heterojunction polymer solar cells—extra energy is able to migrate from one molecule to another over long distances. The dye, which is highly absorbent in the near-infrared region, both broadens the spectral absorption of solar cells and enhances electricity transmission,” Physorg explains.<

New flash mob law to get tough on social media users

See on Scoop.itTwitter & Social Media

According to a Huffington Post report and other media sources, on Friday, Illinois got a step closer to getting tough on persons who place posts on the Internet

Duane Tilden‘s insight:

>The lawmakers passed the measure to hopefully stop violent occurrences in which persons have gathered, run the streets and stopped traffic, robbed, and terrorized people. The flash mobs of note in Chicago have occurred along Michigan Avenue – the Magnificent Mile which is known for its high-end shops and stores. Other areas frequented by tourists have been targeted by the flash mob activists as well.<
