Town looks at way to dispose of its sludge

See on Scoop.itGreen & Sustainable News

GREENFIELD — The town is looking at how it might dispose of its own sludge in the future to save

Duane Tilden‘s insight:

Town officials believe an anaerobic digester and combined heat and power facility would eliminate the costs associated with shipping the wet solids, as well as the cost to heat and provide electricity to the transfer station.

This is not just a matter of saving money, though,” said Collins. “It is also a social justice issue. A lot of these plants, like the ones we transport to, are closing down. We really need to be dealing with our own sludge, not sending it off into other communities.”

[…]  anaerobic digestion is a natural process where sludge (plant and animal waste) is broken down by micro organisms, which release the methane, or biogas, that can be used to generate heat and electricity.

“This helps cut fossil fuel use and reduce greenhouse gas emissions,”[…] “The remaining material is rich in nutrients and can be used as fertilizer.”

German village delivers great green energy blueprint

See on Scoop.itGreen Energy Technologies & Development

Nations as diverse as North Korea and the United States have sent personnel to a tiny village in the east of Germany in a bid to understand its successful energy transformation.

Duane Tilden‘s insight:

…Feldheim is powered by a mix of 43 wind turbines, a woodchip-fired heating plant and a biogas plant that uses cattle and pig slurry as well as maize silage.

Local energy costs of 16.6 euro cents per kilowatt hour (kWh) are just a little more than half of the 27-30 cents Germans pay on average …

Feldheim’s rates are not far off those in Poland, which generates nearly all its electricity from carbon-intensive coal-fired plants.  Households there paid on average 14 cents per kWh in 2012, while those in the Czech Republic, which relies on nuclear for about a third of its power generation, paid about 15 cents per kWh.

DT:  Current electricity pricing in Canada is 6.3 to 11.8 cents/kWh (US$) & United States is 8 to 17 cents/kWh (US$) ~ wiki

Novel Active Energy Material Combines Solar Energy Generation and Power Storage

See on Scoop.itGreen Energy Technologies & Development

Premier Global – DayStar Technologies, Inc. Premier Global Holdings announced that it has demonstrated an active energy material that is the first to combine solar energy generation and power storage into one cell at the molecular level.

Duane Tilden‘s insight:

Laboratory tests validated energy storage capacity exceeding 26 hours, zero degradation and a road map for significantly longer storage times with additional optimization. It is believed that this is the first time sunlight has been captured and simultaneously stored in a highly efficient, low-cost format.

This technology was developed at the University of British Columbia (UBC) and addresses the natural intermittency associated with sun and cloud cover thereby making solar power available anytime day or night. The home is only one application as the technology naturally lends itself as a built-in solution for anyone who uses electricity — including those 1.6 billion without electricity in the remote regions of China, India and Africa.

Revolutionary Green Energy Storage Technology Issued Australian Patent

See on Scoop.itGreen Energy Technologies & Development

Texzon Utilities announces 4th patent for Invention that stores AC power as real AC power, making it the first and only AC battery.

Duane Tilden‘s insight:

“This technology is a game-changer. The ability of the RPM to clean (get rid of all harmonics), magnify power, and store energy as a traveling electro-magnetic wave enables it to react instantaneously as a continuous “elastic reservoir,” which is an innovative and timely solution for Smart Grids,” said General Mike Miller, CEO of Texzon.

About James Corum, Inventor:
Dr. Corum was cited as a “National Treasure” by The Office of the US Secretary of Defense for his work on the DARPA National Panel of Radar Experts on Ultra-Wideband Radar and Phenomenology. His electromagnetic research has been recognized by prestigious scientific organizations and professional societies around the world.

Imagining the Supergrid: HVDC Loops for High Penetration of Renewable Energy | The Energy Collective

See on Scoop.itGreen Energy Technologies & Development

The piecemeal way that the grid is being reinforced today is not compatible with a future supergrid incorporating renewable energy sources. This post examines an alternative layout for new HVDC connections for a future supergrid.

Duane Tilden‘s insight:

The case for a supergrid is very sensibly made by several organizations, …

GW must be transmitted thousands of km) so that the aggregate reliability of wind and solar are greatly improved, because generators in different weather regions can share capacity.

Since weather systems are typically ~ 2500 km (~1500 miles) across, the supergrid does not begin to fulfill its potential until it is quite large, after many billions of dollars have been invested.

This factor is very much holding up practical movement towards a supergrid, and what we are currently getting instead is a patchwork of transmission upgrades that are economically inefficient point-to-point connections that will not later fit in as components of a future supergrid. …

Alliance Pipeline partners with GE to turn waste heat into energy

See on Scoop.itGreen Energy Technologies & Development

Whitecourt project is a first for the Calgary-based pipeline company

Duane Tilden‘s insight:

 The Whitecourt Recovered Energy Project captures exhaust heat from Alliance’s compressor stations northwest of Edmonton. The heat is transferred into a closed loop system and powers one of three 40,000-horsepower gas turbines at the site. The power system creates 14 megawatts of baseload electricity. It is expected to be tied into the provincial power grid in May 2013.

Waste Heat to Energy Firm to Buy Landfill for $9m – Waste Management World

See on Scoop.itGreen Energy Technologies & Development

Largo, Florida based GDT Tek, a specialist in the use of the use of the Organic Rankin Cycle principal to generate electricity has entered into an agreement in principal to purchase 100% of a landfill gas to energy company.

Duane Tilden‘s insight:

According to the company its system has been proven through a long-term five year installation at a San Jose, California landfill, where waste heat captured from the generator’s engine exhaust and cooling systems is used to generate electricity which is then sold to the grid.

“This acquisition once completed will allow GDT Tek to install our Phoenix units at the landfill location and increase revenue by up to 20%,” explained Bo Linton, President of GDT Tek.

Recycling makes $en$e – Waste Management World

See on Scoop.itGreen & Sustainable News

For an increasing number of municipalities across Pennsylvania, recycling is as good for the pocketbook as it is for the environment.  That’s been the case in Cranberry, where modern collection methods and recycling programs have lowered collection fees for residents.

Duane Tilden‘s insight:

By limiting how much goes into landfills and boosting totals of recycled goods, municipalities such as Cranberry have become eligible for state grants – either to operate recycling programs or to expand existing ones.

The amount of waste the municipality sends to landfills was 7,619 tons last year, compared with 11,030 tons in 2004. The average amount recycled per person was 670 pounds last year, up from 115 pounds in 2004.

The Most Important Man in Energy Storage? Try Archimedes – Forbes

See on Scoop.itGreen Energy Technologies & Development

A growing number of energy storage start-ups are promoting the idea that the most economical, most expedient ways to store power revolves around harnessing the four elements of the ancient world: earth, air, water and fire.

Duane Tilden‘s insight:

Energy Cache, for instance, is developing a system that resembles a ski lift for gravel. Gravel is ferried uphill during the day by a series of buckets, and then dropped during peak power hours. The system essentially provides the drop in elevation nature left out.

An Energy Cache system could be erected at a large number of abandoned mining sites, where there is plenty of gravel and an existing grid connection,  […] Along with the physics, the company is analyzing algorithms to ensure smooth power deliver on demand for the power grid. …
