The future of energy

Jun 19th 2008
From The Economist print edition

A fundamental change is coming sooner than you might think

Instead of bullying and scaring people, the prophets of energy technology are attempting to seduce them. They promise a world where, at one level, things will have changed beyond recognition, but at another will have stayed comfortably the same, and may even have got better.

This time it’s serious

Alternative energy sounds like a cop-out. Windmills and solar cells hardly seem like ways of producing enough electricity to power a busy, self-interested world, as furnaces and steam-turbines now do. Battery-powered cars, meanwhile, are slightly comic: more like milk-floats than Maseratis. But the proponents of the new alternatives are serious. Though many are interested in environmental benefits, their main motive is money. They are investing their cash in ideas that they think will make them large amounts more. And for the alternatives to do that, they need to be both as cheap as (or cheaper than) and as easy to use as (or easier than) what they are replacing.

For oil replacements, cheap suddenly looks less of a problem. The biofuels or batteries that will power cars in the alternative future should beat petrol at today’s prices. Of course, today’s prices are not tomorrow’s. The price of oil may fall; but so will the price of biofuels, as innovation improves crops, manufacturing processes and fuels.

Electrical energy, meanwhile, will remain cheaper than petrol energy in almost any foreseeable future, and tomorrow’s electric cars will be as easy to fill with juice from a socket as today’s are with petrol from a pump. Unlike cars powered by hydrogen fuel cells, of the sort launched by Honda this week, battery cars do not need new pipes to deliver their energy. The existing grid, tweaked and smartened to make better use of its power stations, should be infrastructure enough. What matters is the nature of those power stations.

The price is right

They, too, are more and more likely to be alternative. Wind power is taking on natural gas, which has risen in price in sympathy with oil. Wind is closing in on the price of coal, as well. Solar energy is a few years behind, but the most modern systems already promise wind-like prices. Indeed, both industries are so successful that manufacturers cannot keep up, and supply bottlenecks are forcing prices higher than they otherwise would be. It would help if coal—the cheapest fuel for making electricity—were taxed to pay for the climate-changing effects of the carbon dioxide produced when it burns, but even without such a tax, some ambitious entrepreneurs are already talking of alternatives that are cheaper than coal.

Coalition and Partners Launch Rebuilding America

The Energy Future Coalition, in concert with a diverse cross-section of partners, recently submitted a plan to Congress to use building retrofit programs to put people back to work while reducing the U.S.’s energy footprint.  The building sector consumes 70% of electricity and emits 40% of U.S. greenhouse gas emissions.  Implementing energy efficiency retrofits presents an opportunity to create good jobs that not only reduce our environmental impact, but also create long-term energy savings for schools, homes, and businesses.

The plan would target retrofitting 4 million homes over the next two years.  Over the long-term, the plan recommends improving the efficiency of 50 million existing structures by 2020, creating 200,000 jobs. Energy efficiency is much cheaper than building new power plants and should be the first option for meeting energy demand.

Solar Energy “Power Towers” for California

Solar Power Towers California We mostly talk about solar panels that convert sunlight into electricity. But we can utilize sunlight by using another technology known as concentrating solar technology. In this technology reflective mirrors are used to concentrate light onto a liquid to make steam. This steam then converts energy into electricity with the help of conventional turbines. Deserts are best places to avail this technology. One important aspect is, its air-cooling process conserves water, an important consideration for desert projects. Concentrating solar technology is to be utilized in California which has a directive to generate 33 percent of their electricity from renewable sources by 2020. 8 Comments

EPA Raises Raises Requirements for Renewable Fuels

An item of interest to ethanol producers and other supporters of ethanol is this announcement by EPA, as further clarified by this announcement by EERE:

Epaseal1

The U.S. Environmental Protection Agency (EPA) announced on November 17 that the 2009 renewable fuel standard (RFS) will require most refiners, importers, and non-oxygenate blenders of gasoline to displace 10.21% of their gasoline with renewable fuels such as ethanol. That requirement aims to ensure that at least 11.1 billion gallons of fuels will be sold in 2009.  . . . While the RFS requirement is increasing by about 23%—from 9 billion gallons in 2008 to 11.1 billion gallons in 2009—the percentage requirement is increasing by nearly one third, from 7.76% in 2008 to 10.21% in 2009.

Let engineers make Britain great again

The Guardian has a fairly technocractic article on the low value accorded to engineers in Britain and the value of implementing some large scale and tecnically complex infrastructure to rebuild the economy on “solid foundations” – Let engineers make Britain great again.
Orson Welles said film-making was the biggest electric train set a boy ever had. He was wrong. A new high-speed train line would be, if the boy or girl grew up to engineer it.

But in Britain, the train set is broken and has been packed away in the attic. We’re not proud of industry and we certainly don’t want our kids to grow up to be engineers. It’s a tragedy. It never used to be this way. We need to rediscover the power of engineering, its impact and contribution. It can stimulate young minds and it can stimulate the economy. …

So the young are innately curious about how and why things work. Yet what happens between childhood and adulthood? We stamp it out of them. Engineering gets stigmatised and we encourage our kids to become “professionals” – lawyers, accountants, doctors. Unlike in France or Germany, engineers are a bit of a nonentity here. Engineering is almost a dirty word. We’re told it’s “old industry” and that we are a “post-industrial nation”.

Part of the problem is that engineers are not accorded the status they deserve. We celebrate designers and architects, but forget the clever people who turn the theory into reality. The Millau bridge in France was designed by Norman Foster, but it was French engineer Michel Virlogeux who made it work. A magnificent achievement, but whose name do people remember? In 2005, Ellen MacArthur became the fastest person to sail round the globe, but little was made of Nigel Irens, who engineered her trimaran. …

Damn it man…Engineers are important…but so are their mothers and they never mention them.

Crude Reality: Oil Bulls See Hope in Stimulus Package

Crude oil futures in New York are still climbing Monday, jumping more than 5% in early trading before settling down to a more modest 1.5% increase.

What’s driving the uptick? There are theories for all tastes.

On the supply side, OPEC now says it is doing better at sticking to reduced production targets than most outside analysts give the cartel credit for. OPEC’s secretary general said today the cartel has already cut 80% of the 4.2 million barrels it’s meant to take off the market, and the cartel is ready to cut again at its March meeting.

On the demand side, President Obama’s cheerleading for the $800-odd billion stimulus package and signs the Senate could pass its version tomorrow are giving bulls hope there’s a quick fix in store for the battered U.S. economy that will rekindle demand for oil. Given that natural-gas futures are also up on Monday—the first four-day winning streak for gas since last autumn—there’s something to be said for the idea of a light at the end of the tunnel for the U.S. economy.

But the imminent passage of the stimulus package could be bullish for oil prices—without ever stimulating a lick of oil demand in the U.S.

Insuring electric cars

Submitted by Bruno De Wachter on Thu, 2009-02-05 06:30.

 

Cheaper or more expensive than conventional cars?

When the cost of a plug-in vehicle is mentioned, it mostly refers to the purchasing and maintenance expenses. Sometimes, tax reductions given to electric vehicles (EVs) are taken into account, but the insurance cost is rarely discussed. This is somewhat strange, since the insurance on a conventionally fuelled car accounts for roughly one quarter of its fixed cost of ownership. So, what happens to this cost when switching from a conventional car to an EV?

Green Roofs – The ultimate water recycler

Green Roofs or the idea that you could grow plants on the roof as a form of insulation and an absorber of water are gaining traction in the US Market. This new, some would say radical, idea is actually not new for people who live in rammed earth homes and underground or planned caves. These structures seed what are their roofs with grass. In the summer they allow the grass to grow tall which adds insulation value to the home. Green Roofs are this idea transferred up in the air.

I think that this idea would work best for low slope roofs with some access to enjoy the greenery. We have a sharply sloped roof so it would not work on our house. We have low sloped roofs on the garage and a very large shed so we could do Green Roofs there. It has the advantage of some carbon sequestration as well, depending on what you do with the green waste.

http://www.toolbase.org/Technology-Inventory/Roofs/green-roofs

Green roofs, also called living or planted roofs, are systems of living plants and vegetation installed on the roof of an existing or new structure. The green roof concept is not new. The Hanging Gardens of Babylon constructed around 500 B.C. were perhaps one of the first green roof systems. Planted components of a prevegetated modular green roof system. Photo courtesy of LiveRoof, LLC Terrace structures were built over arched stone beams and waterproofed with layers of reeds and thick tar on which plants and trees were placed in soil.

Popular in Europe for decades, technology has improved upon the ancient systems, making green roofs available in and appropriate for nearly all climates and areas of the United States. All green roof systems consist of four basic components: a waterproofing layer, a drainage layer, a growing medium, and vegetation. Some green roofs also include root retention and irrigation systems, but these are not essential.

Green roof systems are often broken down into two types—extensive and intensive systems. An extensive system features low-lying plants such as succulents, mosses, and grasses. They require relatively thin layers of soil (1-6 inches), and plants usually produce a few inches of foliage. Extensive systems have less of an impact on the roof structure, weighing 10-50 pounds per square foot on average, and are generally accessible only for routine maintenance. Most residential applications are composed of extensive green roof systems. Intensive systems feature deeper soil and can support larger plants including crops, shrubs, and trees. Intensive systems can be harder to maintain, depending on the plants used, and are much heavier than extensive systems—they range from 80 to more than 120 pounds per square foot. Intensive systems are typically designed to be accessible to building inhabitants for relaxation and/or harvesting.

:}

For people who are “doing it” so to speak:

http://www.hadj.net/green-roofs/project-info.html

Welcome to the project! We intend to examine the feasibility of green roofs (extensive roof gardens) for residential scale construction. As you know, green roofs are common in Germany, France, Swizerland, and England, and are gaining a foothold in Canada and the U.S.

However, the vast majority of these roofs are commercial scale. The total area of residential roof surface, compared to commercial roof surface, is much larger and has a much more profound impact on the environment. Also, the largest and fastest growing encroachment on open space and riparian waterways is not commercial but residential development.

There are several challenges to developing a residential market:

  • The intial cost of green roofs is higher (however, their life cycle cost is competitive with conventional roofs).
  • Builders and developers want to offer a low sticker price for their product. They are responding to a market that does not frequently calculate life cycle costs.
  • Weight: the 3″ to 6″ of soil plus geotextiles on a roof can require added structure. In seismic zones there is a concern in that more weight is placed higher up in a structure.
  • The simple novelty of green roofs. I remember when the U.S. construction industry was talking about going metric, 35 years ago.

Home Improvement for the Planet

Green roofs or eco roofs are an excellent way to reduce energy costs and reduce urban “heat island” effects that increase atmospheric temperatures. A green roof is a roof that is covered with vegetation. Green roofs are still relatively scarce in the United States today but appeared throughout the Midwest prairie homes of decades gone by. They are common throughout European commercial and residential areas today, covering over 100 million square feet of rooftops.

In both commercial and residential applications, green roofs offer many benefits to property owners. Green roofs reduce energy costs by adding insulation in winter and absorbing heat in summer. Estimates of energy savings range from 6-50% depending on the roof size. When installed in new construction, the incorporation of a green roof into the project’s design allows a reduction in the size of heating and cooling systems needed. This adds an upfront savings s smaller units may be installed for smaller heating and cooling loads. In today’s housing market, energy savings equals increased property value. Some green roof projects are eligible for tax credits and other “green” incentives. Green roofs transform impervious surfaces such as tar and asphalt into useable green space that absorbs solar radiation and carbon dioxide.

Until now, green roofs in residential areas have been outnumbered by commercial coverage because the task of installing a green roof can be overwhelming for individual home owners. In part this is due to expense but also attributed to a lack of knowledge in general about green roofs, their benefits and how to install them. As such an important feature of a home’s structural soundness, the thought of an “outside the norm” roof treatment can be intimidating.

Water Cisterns – Once you have done the little stuff there is so much you can do

LowFlow Showerheads are mandatory but once you start there is serious stuff you can do to save water. Cisterns. It used to be that everyone had them. Some were as simple as a hole in the ground covered with screening. Sometimes they were even built as part of the house. Sort of your own personal water tower. But with the advent of modern drinking water systems they fell by the wayside.

http://www.harvesth2o.com/plumbing_codes.shtml

History

Cisterns are an ancient technology. In the Middle East in 2000 B.C., typical middle-class dwellings stored rainwater in cisterns for use as a domestic supply as well as private- bathing facilities for the wealthy.

The world’s largest cistern may be the Yerebatan Sarayi. On the European side of Istanbul in Turkey, it was constructed under Caesar Justinian (A.D. 527-565) and measures 140 by 70 meters. It can store 80,000 m³ water. The underground structure is based on intersecting vaults. Today, it is a tourist attraction which is visited by boat, drifting through a forest of columns. Another cistern in Istanbul is called Binbirdik, believed by some sources to have been constructed under Caesar Constantine (A.D. 329-337), with a capacity of 50,000 m³. Each cistern served as centralized storage for water collected from roofs and paved streets and featured a sophisticated system of filters that assured clean water.

These municipal underground cisterns may be the only examples of urban centralized rainwater harvesting of their kind. This technique was likely abandoned for two primary reasons: 1) the construction of underground cisterns is considerably more expensive than the construction of dams; 2) there is a danger of accidental pollution through human excrement in dense urban areas and a corresponding risk of epidemics.

Water Classifications

Harvested rainwater is shrouded in confusion. Some jurisdictions consider it reclaimed water and others refer to it as gray water. Actually, it is neither. To clarify, UPC offers the following definitions.

• Black water is toilet waste.

• Gray water is untreated wastewater that has had no contact with toilet waste such as used water from bathtubs, showers, lavatories and water from washing machines. It does not include wastewater from kitchen sinks or dishwashers.

• Reclaimed water is water which, as a result of tertiary treatment of domestic wastewater by a public agency, is suitable for controlled use. The controlled use can be the supply of reclaimed water-to-water closets, urinals and trap seal primers for floor drains and floor sinks. In areas under the jurisdiction of the UPC this system is usually called a “purple pipe” system because the reclaimed water is conveyed in pipe that is purple.

• Harvested rainwater is storm water that is conveyed from a building roof, stored in a cistern and disinfected and filtered before being used for toilet flushing. It can also be used for landscape irrigation.

As noted, Appendix J of the UPC describes reclaimed water, but according to the above definition, rainwater harvesting is not reclaimed water. Plumbing officials who do not know how to classify rainwater-harvesting systems consider them reclaimed water systems and therefore require plumbing engineers to design systems that conform to Appendix J of the UPC. This is because of the lack of guidance in the code. Since these systems are becoming more prevalent in the U.S., both the UPC and the IPC must include a section dedicated to rainwater harvesting.

Rainwater Harvesting Basics

The components of the rainwater-harvesting system include:

Roof. Rainwater should only be collected from a roof and stored in a cistern. Rainwater runoff from parking areas and other outdoor surfaces typically contain harsh chemicals and other contaminants that are undesirable in a rainwater catchment system.

Rainwater conductors. Leaders and gutters or an internally piped roof drainage system that conveys the storm water from the roof to the cistern.

Cistern. A storage tank that allows large particulate matter to settle out of the water.

Overflow from cistern. A pipe that takes overflow from the cistern to the storm drainage system.

Pumping system. Provides the pressure required at the fixture most distant from the tank.

Disinfection system. Various filtration and disinfection systems can be used.

Potable water makeup. Makeup water provided to the tank during dry seasons. Appropriate backflow prevention is required.

:}

But this is to CODE which may or may not apply…First you have to figure out where you are going to put the water.

Rainwater Harvesting

As much as 60,000 gallons of precipitation falls on a 2,000 square foot roof in Mid-Atlantic States each year. BRAE distributes Complete rainwater harvesting system solutions to put this water to beneficial use. Rainwater harvesting systems offset demands on municipal and private water supplies for outdoor watering while conserving valuable drinking water resources.

The concept of collecting and using rainwater is not new.

In addition to the advantages that rainwater is free of charge, it doesn’t have to be treated nor transported over long distances, the two most important arguments supporting the utilization of rainwater are:

1. Supplement drinking water resources
-with the benefit of saving precious potable water
2. protecting water quality by reducing impacts of stormwater runoff
-with the benefit of limiting flooding and degradation of streams and lakes

Thanks to its characteristics the use of rainwater also has positive advantages:
-Ideal for plant growth
-Better washing efficiency -up to 50% less detergent required when compared with hard water
-No calcification of fixtures and washing machines

All projects are not created equal and thus rainwater systems do not conform to a “one size fits all” sales format. There are different systems for two primary types of rainwater systems residential and commercial. Use the following resources to design and select the right system for your project.

Residential systems generally supply rainwater to toilets, washing machines, garden irrigation and hosebibs (ie car washing)

http://www.braewater.com/index.php?/products/tanks_cisterns/

Tanks/Cisterns

Water storage is the most critical component of a rainwater system. In selecting a water storage tank or cistern, there are several important questions you should ask before selecting the right tank for your project.Ask yourself…

Will I store the water above ground or below ground?
How much storage do I need?
Are there space limitations that restrict the size of water tank I may chose?
What appearance do I want for my tank?
Will the neighbors care?
Are there restrictions regarding water storage tanks?
Is my site accessible or hard to reach with a delivery truck?

Aerogel Insulation Advances

Published on April 11th, 2008

Posted in Energy, Heating & Cooling, Materials

Aerogel is almost a product out of science fiction.

Nicknamed “frozen smoke,” aerogel is extremely lightweight material, with a density only 3 times that of air. Only a small fraction of a volume of aerogel is the material itself. Most of the volume is filled with air. This makes aerogel an excellent insulator. (Aerogel provides nearly 40 times the insulation of fiberglass insulation.)

Aerogel can withstand great pressures and is also an excellent sound insulator. Aerogels can also be used to absorb airborne pollutants and have been used to clean up oil spills. NASA also used a section of aerogel as part of its Stardust probe to collect samples of material from the tail of a comet.

Aerogel is available for some high-performance applications, but due to its high cost, it has not been widely used. However, new research from a Malaysian scientist offers the potential to drastically reduce the cost of producing aerogel, and could lead to new possibilities for its use as a building and insulation material.

Dr. Halimaton Hamdan from the Universiti Teknologi in Malaysia has developed a method of producing aerogel that could reduce the cost of producing aerogel by 80% by using agricultural waste from rice husks as the feedstock. Rice husks evidently have a high silica content, and silica is the main constituent of aerogel. In addition to potentially being able to produce aerogel for one-fifth the current cost, this also addresses a problem with disposing of rice husk waste.

Because aerogel is translucent, rather than completely transparent, one of the places it has first been used in architectural applications has been in daylighting panels. Commercial applications of aerogel are from companies such as Kalwall and Advanced Glazings,…..

Spray Foam Insulation

Drastically Decreases Air Leakage from a Home

Andrew Stratton

According to the US Department of Energy, more than half of the energy cost of the average home goes into heating and cooling. Furthermore, 30% of the heating and cooling cost is the result of air infiltration. One of the newest advancements in home products, expanding spray foam insulation, can significantly reduce the amount of air leakage within a house.

Air leakage is often most noticeable during winter months. This is because it is during the winter that the maximum temperature difference exists between the warm interior and the cold exterior of a house. This maximum difference in temperature causes a large pressure discrepancy between a home’s inside and outside environments. In turn, this pressure discrepancy causes the warm inside air to be pushed through any small gaps to the cold laying outdoors. Therefore, these small gaps allow the heat which you paid for to escape from your house.

Expanding spray foam insulation can plug these small holes. The spray foam insulation accomplishes this task by expanding into the small gaps onto which it has been sprayed.

However, to be effective it may be helpful to understand where these small holes may occur. One often thinks of the spaces near a door or window when thinking about the possible locations where currents may arise. However, there may be other locations which are not as apparent. These other locations are usually less apparent because they are found within the attic, basement or crawlspace.

Spray Foam: Environmentally

Friendly Insulation

Andrew Stratton

Everyone is going green, and many companies are making it easier than ever. If you want to do your part for the environment, a great way to start is right in your own home. With the advent of new technologies, there are now products available that will help keep the environment healthier without having to compromise your own comfort.

Spray foam insulation is one product for your home that has recently gone green. Spray foam insulation begins as liquid polyurethane that is then sprayed onto surfaces, creating a protective, insulating barrier. Since the foam is initially liquid, it easily covers all cracks and holes in the wall, covering a more thorough area than fiberglass or cellulose.

This means that your house will be more climate efficient. The heat will stay trapped inside during the cold months and the cool air will stay in during the summer. Not only will the temperature of your house be more comfortable, but you’ll save energy on your heating and cooling.

Hydrokinetic Turbines Are Another Arrow In The Green Quiver – Side hung generators should be in every stream in America

 Nation’s First ‘Underwater Wind Turbine’ Installed in Old Man River

By Alexis Madrigal EmailDecember 22, 2008

The nation’s first commercial hydrokinetic turbine, which harnesses the power from moving water without the construction of a dam, has splashed into the waters of the Mississippi River near Hastings, Minnesota. The 35-kilowatt turbine is positioned downstream from an existing hydroelectric-plant dam and — together with another turbine to be installed soon — will increase the capacity of the plant by more than 5 percent. The numbers aren’t big, but the rig’s installation could be the start of an important trend in green energy.And that could mean more of these “wind turbines for the water” will be generating clean energy soon.“We don’t require that massive dam construction, we’re just using the natural flow of the stream,” said Mark Stover, a vice president at Hydro Green Energy, the Houston-based company leading the project. “It’s underwater windpower if you will, but we have 840 or 850 times the energy density of wind.”Hydrokinetic turbines like those produced by Hydro Green and Verdant capture the mechanical energy of the water’s flow and turn it into energy, without need for a dam. The problem for companies like Hydro Green is that their relatively low-impact turbines are forced into the same regulatory bucket as huge hydroelectric dams. The regulatory hurdles have made it difficult to actually get water flowing through projects.

The Federal Energy Regulatory Commission has oversight of all projects that involve making power from water, and the agency has recently shown signs of easing up on this new industry. In the meantime, the first places where hydrokinetic power makes in impact could be at existing dam sites where the regulatory red tape has already been cut.

State of River Energy Technology”

Jahangir Khan, Powertech Labs, British Columbia, Canada.  2006.Based on the available formal literature, the very first example of river turbine that was developed and field tested is attributed to Peter Garman. An initiative by the Intermediate Technology Development Group (ITDG) in 1978 resulted in the so-called Garman Turbine specifically meant for water pumping and irrigation. Within a period of four years, a total of nine prototypes were built and tested in Juba, Sudan on the White Nile totaling 15, 500 running hours. Experience gained during this venture indicated favorable technical and economical outcome. Initial designs had a floating pontoon with completely submerged vertical axis turbine, moored to a post on the bank. Later designs consisted of an inclined horizontal axis turbine with almost similar floatation and mooring system. Detailed investigation on a low cost water pumping unit indicated 7% overall efficiency and concluded with emphasis on societal and cost issues. More recent commercial ventures resulting from this work are being pursued by Thropton Energy Services, Marlec Engineering Co. Ltd. , and CADDET Center for Renewable Energy.

SeaGen – Need I say more?

A generation ago those of us in the alternative energy world, utility policy and energy conservation had a one word battle cry. Hood River. The town in Oregon that demonstrated many of the priniciples that we had fought for and Energy Corporate America had fought against. Well SeaGen is one of THOSE.

SeaGen Shatters Tidal Power Generation Record

 Written by Timothy B. Hurst

Published on December 18th, 2008

Posted in alternative energy

 Since its inception, we have been keeping a close eye on Marine Current Turbine’s SeaGen project in the UK, the world’s first commercial scale tidal stream turbine. Well, today there is more big news to report from the strong tidal flows of Strangford Lough as SeaGen has generated at its maximum capacity of 1.2MW for the first time. Thus far, this is the highest power produced by a tidal stream system anywhere in the world and exceeds the previous highest output of 300kW produced in 2004 by the company’s earlier SeaFlow system, off the north Devon coast.

Generating at full power is an important milestone for the company, and in particular our in-house engineering team. We are very pleased with SeaGen’s performance during commissioning,” said Martin Wright, Managing Director of Marine Current Turbines (MCT). “It demonstrates, for the first time, the commercial potential of tidal energy as a viable alternative source of renewable energy.”

According to company officials, now that SeaGen has reached full power it will move towards full-operating mode for periods of up to 22 hours a day, with regular inspections and performance testing undertaken as part of the project’s development program.

Now The Environmentalists Have Discovered There Is No Clean In Coal – I am shocked

I believe in carbon sequestration because I believe that carbon and other elements in smokestack effluent can be recycled. That is they can be used for feedstock for algae or concrete. Injecting it into the ground however is not an option. I have said that for 10 years while everyone else was sucking up to the power companies.

Blowing Smoke

Is clean coal technology fact or fiction?

By Daniel Stone | Newsweek Web Exclusive

Dec 9, 2008 | Updated: 8:08  a.m. ET Dec 9, 2008

 A single power plant in western Pennsylvania is one of the 12 biggest carbon dioxide polluting power plants in the U.S. emitting 17.4 million tons annually.

In the elusive search for the reliable energy source of the future, the prospect of clean coal is creating a lot of buzz. But while the concept—to scrub coal clean before burning, then capture and store harmful gases deep underground—may seem promising, a coalition of environment and climate groups argue in a new media campaign that the technology simply doesn’t exist.

The Alliance for Climate Protection and several other prominent organizations—including the Sierra Club and National Resources Defense Council—launched a multipronged campaign to “debrand” the clean part of clean coal, pointing out that there’s no conclusive evidence to confirm the entire process would work the way it’s being marketed. In the campaign’s TV ad, a technician sarcastically enters the door of a clean coal production plant, only to find there’s nothing on the other side. “Take a good long look,” he says, standing in a barren desert, “this is today’s clean coal technology.”

The campaign was designed to combat the well-funded coal industry, which formed a trade association in April to promote the idea of clean coal. Joe Lucas, a vice president for the American Coalition for Clean Coal Electricity, says that the technology does exist, although it’s still in early development stages. “With the current research being done, we think we can get the technology up and running within 10 to 15 years,” he says. Activists like Brian Hardwick, chief spokesman for the Alliance for Climate Protection, aren’t so sure. Hardwick spoke to NEWSWEEK’s Daniel Stone about why the idea of clean coal shouldn’t be considered a solution.

What is clean coal technology?

by Sarah Dowdey

Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain and pollute water. With all of the hoopla surrounding nuclear energy, hydropower and biofuels, you might be forgiven for thinking that grimy coal is finally on its way out.

But coal is no sooty remnant of the Industrial Revolution — it generates half of the electricity in the United States and will likely continue to do so as long as it’s cheap and plentiful [source: Energy Information Administration]. Clean coal technology seeks to reduce harsh environmental effects by using multiple technologies to clean coal and contain its emissions.

When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle.

Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates. Wet scrubbers, or flue gas desulfurization systems, remove sulfur dioxide, a major cause of acid rain, by spraying flue gas with limestone and water. The mixture reacts with the sulfur dioxide to form synthetic gypsum, a component of drywall.

Low-NOx (nitrogen oxide) burners reduce the creation of nitrogen oxides, a cause of ground-level ozone, by restricting oxygen and manipulating the combustion process. Electrostatic precipitators remove particulates that aggravate asthma and cause respiratory ailments by charging particles with an electrical field and then capturing them on collection plates.

Where do the emissions go?

Carbon capture and storage — perhaps the most promising clean coal technology — catches and sequesters carbon dioxide (CO2) emissions from stationary sources like power plants. Since CO2 contributes to global warming, reducing its release into the atmosphere has become a major international concern. In order to discover the most efficient and economical means of carbon capture, researchers have developed several technologies.

Coal isn’t going anywhere soon — it generates half of the U.S. power supply.

Flue-gas separation removes CO2 with a solvent, strips off the CO2 with steam, and condenses the steam into a concentrated stream. Flue gas separation renders commercially usable CO2, which helps offset its price. Another process, oxy-fuel combustion, burns the fuel in pure or enriched oxygen to create a flue gas composed primarily of CO2 and water — this ­sidesteps the energy-intensive process of separating the CO2 from other flue gasses. A third technology, pre-combustion capture, removes the CO2 before it’s burned as a part of a gasification process.

:}

Here is where the bullshit starts, “Why would they have to do anything after sequestration?”

:}

After capture, secure containers sequester the collected CO2 to prevent or stall its reentry into the atmosphere. The two storage options, geologic and oceanic, must contain the CO2 until peak emissions subside hundreds of years from now. Geologic storage involves injecting CO2 into the earth. Depleted oil or gas fields and deep saline aquifers safely contain CO2 while unminable coal seams absorb it. A process called enhanced oil recovery already uses CO2 to maintain pressure and improve extraction in oil reservoirs.

Poor nations to get funds

 to fight climate change

POZNAN, Poland – Negotiators at a U.N. climate conference broke through red tape and freed up millions of dollars Friday to help poor countries adapt to increasingly severe droughts, floods and other effects of global warming.“This could be the one thing to come out of Poznan,” said Kit Vaughan of WWF-Britain.The decision in the final hours of the two-week conference could begin to release some $60 million (euro45 million) within months, according to delegates and environmentalists following the closed-door talks.“This is an important step,” said delegate Mozaharul Alam of Bangladesh.Alam said ministers and senior delegates from dozens of countries decided to give a blocked fund’s governing board the authority to directly disburse money to developing countries for projects to reduce greenhouse gases.

Until now, the U.N.-backed Adaptation Fund board could not operate because its board had no right to approve and sign those contracts.

The fund is derived from a 2 percent levy on offset investments that industrial nations make on green projects in the developing world. The negotiators have been discussing other ways to ramp up the fund into the billions.

The agreement was one of the few concrete goals the delegates set for Poznan when the talks began Dec. 1. Delegations from nearly 190 countries are negotiating a new climate change pact, to be completed next December in the Danish capital of Copenhagen, that would succeed the Kyoto Protocol when it expires in 2012.

So You Think I Hate Coal Companies – Well actually I do but apparently they have their uses

Old Coal Mines Adapted

to Generate Geothermal Energy

by Bridgette Steffen

December 10, 2008

 Recently the town of Heerlen in the Netherlands repurposed an old abandoned coal mine into a brilliant source of geothermal energy. The project takes advantage of flooded underground mine shafts, using their thermal energy to power a large-scale district heating system. Dubbed the Minewater Project, the new system recently went online and provides 350 homes and businesses in the town with hot water and heating in the winter and cool water in the summer.

 In the Netherlands, coal was one of the main sources of energy from the turn of the century up until around 1959, when large amounts of cheap natural gas were discovered in the north. The coal industry lost market share and mine after mine was closed down – in the city of Heerlen, for instance, the coal mine was closed and the shafts were flooded with water and have been unused for the last 30 years

Five new wells were drilled in various locations around town to access the underground mine shafts. Each well is 700 meters (2,300 ft) deep and can pump out nearly 80 cubic meters (2,800 cubic feet) of water per hour. The water temperature at the bottom of the well is 32 C (89 F) and gradually cools to 28 C at the surface. Warm water from the mine is brought to the surface where a heat pump extracts the heat in order to supply hot water to households in the area. Meanwhile the Minewater is pumped back down 450 meters to be reheated. In the summer, to provide cooling, water will be pumped from a much shallower depth of 250 meters, where it is not so warm.

 The area supplied by the Minewater is a relatively new development and includes a supermarket and a brand new cultural center and library as well as many homes and businesses. While the cost of the heating and cooling is not much different than before, customers can be assured of stable prices in the future compared to the cost they could incur by using fossil fuels.
