COLUMN: Applying existing technologies to store CO2



What is the process by which carbon dioxide is sequestered underground?

There are actually three forms of geologic sequestration being studied by the Illinois State Geological Survey: 1) enhanced oil recovery, where carbon dioxide (CO2) is injected into depleted oil fields to aid in the recovery of oil left in place; 2) coal bed methane recovery, where CO2 is injected into coal seams to displace methane, which can be recovered and used; and 3) storage in deep saline formations, where the CO2 is injected into deep porous rocks. The CO2 is then trapped in pore spaces and kept in place by relatively impermeable rocks directly above. In Illinois, as well as nationally, deep saline reservoirs have the greatest storage potential.

How is a suitable site for carbon sequestration found?

Really, there are two criteria: suitable geology, and knowing you have suitable geology. In Illinois, we have suitable geology, and thanks to the work of the Illinois State Geological Survey, we know it.

The Illinois Basin, a geologic structure that underlies Illinois, southwestern Indiana, and western Kentucky, is well-suited to permanently sequester large quantities of CO2 in deep saline formations. The Mount Simon Sandstone, the target sequestration formation, is a thick layer of porous sandstone underlying much of the state. The Mount Simon is between 4,500 and 6,500 feet beneath the surface and ranges from 1,000 to 1,700 feet thick. The Eau Claire Shale is a 300- to 500-foot-thick, relatively impermeable shale that is directly above the Mount Simon and acts as a seal or caprock.

How much CO2 will be injected into the ground each year?

At the Illinois Basin–Decatur Project, funded by the U.S. Department of Energy, the ISGS is partnering with Schlumberger Carbon Services and the Archer Daniels Midland Company to sequester 1 million metric tons of CO2 over a three-year period at ADM’s ethanol production facility in Decatur. When it is operational, FutureGen could sequester up to 1 million tons per year.

Has this technology been proven to work on such a large scale?

The Sleipner project in the North Sea of Norway has been injecting 1 million tons of CO2 per year since 1995. Additional large-scale projects are either under way or planned throughout the U.S. and around the world. Both FutureGen and the Illinois Basin–Decatur Project will demonstrate sequestration at a large-scale. What we learn from these projects will be used to inform larger commercial projects as they come on line.

Can injecting liquid carbon dioxide into the ground cause earthquakes?

Earthquakes occur when pressure is released along two rock faces. The injection of CO2 is highly unlikely to cause an earthquake, unless it were to be directly injected along a fault plane. Geophysical surveys are run before injection starts to detect and avoid such faults.

Could liquid carbon dioxide migrate, escape from the ground or get into aquifers?

The Illinois Environmental Protection Agency requires that underground sources of drinking water be protected. All sequestration projects are subject to regulation under the Safe Drinking Water Act. The Mount Simon formation is more than a mile below groundwater used as a drinking source. Three major seals, or impermeable rock units, occur between the Mount Simon Sandstone and the surface throughout the Illinois Basin. These seals act as multiple barriers for the movement of CO2 once sequestered.

Do you have confidence that this technology will work?

Geologic sequestration utilizes experience from several existing industries including oil and gas production, natural gas storage, and enhanced oil recovery.

For example, natural gas has been stored underground at more than 30 locations across Illinois without leakage since the 1960s. We are applying these technologies to a new purpose: storing carbon dioxide. Every effort is being made to ensure that sequestration is safe and effective, and the work we are doing now will help us answer this question.

Dr. William W. Shilts, a graduate of DePauw, Miami of Ohio, and Syracuse universities, was named executive director of the Institute of Natural Resource Sustainability on July 1, 2008. The institute, which comprises the Illinois State Geological Survey, Illinois Natural History Survey, Illinois State Water Survey, and the Illinois Sustainable Technology Center, has wide-ranging research and service programs in ground- and surface-water resources, climate, energy and mineral resources, ecosystems, invasive species, three-dimensional geologic mapping, and environmental geology. The INRS provides objective scientific information to state and federal agencies, units of local government, industry, and the public. Dr. Shilts is also adjunct professor with the University of Illinois, the University of Quebec and Illinois State University.

" This would appear to be another of the Clean Coal Advertising less than truths that they seem to roll off their tongues with so little effort! There are actually four forms of geologic sequestration! The one that was left out of the article is probably the most important.

God developed and implemented the Carbon Capture And Sequestration system on Earth!

He captured the carbon dioxide, the mercury, the arsenic, the lead and many of the other hazardous chemicals and bound them up in a matrix that we call coal! He bound up this matrix in such a way so that the materials he put into it would stay sequestered forever! He took that matrix and buried most of it, so it would be well below the life zone of Earth. Locked away forever.

He knew the planet would produce more carbon dioxide than the plants could ever recycle. He knew the mercury would contribute to autism in his children. He knew that arsenic caused death and that lead would cause nerve damage and learning disabilities. He knew if he buried it, it would make it more difficult for us to use it to screw up his creation!

And here we are today, digging up what he has covered up, releasing the poisons he so lovingly protected us from, releasing them into death and destruction in his world! Releasing them into the life zones of his creation!

God invented the sequestration concept, why do we have to keep digging up his work and bringing the pollution back into our lives!

I wonder why the trains that haul the wonderful fuel Clean Coal Advertising coal from the mines to the generator plants don't burn cheap Clean Coal Advertising coal instead of Refined Diesel Oil? They must be willing to spend the extra money for some reason! It couldn't be that the Federal Government quit believing the Clean Coal Advertising scam a long time ago could it? "

Does your solution begin with solar, where we can fence off millions of acres for solar panels - which, by the way, also kills off another CO2 storage area? Or how about those giant wind turbine operations - but not in your back yard, right?

What's your solution? Oh, that's right. You just complain. I guess that's your only contribution, right? "

" gringa - What's my solution?

No I don't live in a grass hut or a log cabin back in the woods! I even understand that CO2 is the primary gas in the life processes that provide you and I with the oxygen that we breath! I also think that we have enough CO2 in the environment already without adding more from burning coal to produce energy.

What's my solution? Oh thats right I just complain! I just complain about the pollution that Clean Coal Advertising companys keep spreading on our land all in the search of cheap electricity all at the time they know the carbon taxes that are being proposed will increase cost for coal beyond any other source of power!

Yeah I don't want those Giant Wind Turbine operations in my back yard though! Thats why I live in the center of the Worlds Largest Wind Operation. When I look North, South, East and West I have the pleasure of seeing wind turbines and can't wait for more to be installed. The turbines don't substantially affect the farming and ranching operations in their footprint and the space occupied by the turbine base pays the land owner between $10,000.00 and $15,000.00 per year for the power thats produced.

That's why when my family from over in Clark County and up in Chicago and over in Indiana come by I am proud to show them the wind farm operations. If you use Google Earth and would like to check out the wind turbines in my back yard enter 3220'21.87"N 10021'32.11"W into the Google Earth search field. While you are at it, enter 44 7'19.66"N 10519'57.03"W thats the loading area for the Clean Coal Advertising coal from the Powder River Coal Mine. See if you can tell which direction the Clean Coal Advertising coal train is traveling on the tracks.

Have I answered your questions gringa?

You didn't answer mine! I wonder why the trains that haul the wonderful fuel Clean Coal Advertising coal from the mines to the generator plants don't burn cheap Clean Coal Advertising coal instead of Refined Diesel Oil? And why don't the local governments require that the open gondola train cars are covered like the trucks that haul open loads on your city streets? "

" If CO2 sequestering is your main issue, I goggled futuregen again, and The State of Illinois gets ownership, and liability for the stored CO2. It has a special resolution, that was on the wiki page, near the bottom.

Here we have another guest lecture of established talking points. I think the CO2 sequestering is one of the least of many much bigger issues. They can pipe it for miles to an injection site, if they want.

When are they going to address the bigger issues. Slag disposal and storage. How much slag, ash, and other hazerdous waste, is expected to be produced annually? How much polluted corn and beans from surrounding fields, will they be buying? How big a radius, is this likely to be an issue? Hydrogen safety and storage. Chemical and heavy metal by products of the process. Lots of loaded and empty coal trains, crossing the marshal ave/21st St. and on west crossings.

How is the very poorly selected site, going to accomidate proper rail access, when the existing rails bisect a corner of the area. Trucks entering and leaving 121, with an immediate rail crossing to contend with, in and out. Dole road, was to be upgraded to get out of area trucks from 57 to 1000N, to cross 121 and enter this site, from money for the 1000N expansion and access. Will there be a new stop light out there to contend with, reduced speeds from mattoon to coles station, or what is the plan? Will the intersection be lighted?

Trucks hauling bulk materials, often get paid by percentage of the load, they often run heavy, and fast. If these new roads, weren't designed with this reality in mind, they will be chewed up in a hurry. Will the site, vigilantly maintain load weight restrictions, in and out? This would require scales, and strict rules for pickup and delivery of materials. Will trucks to and from the sight, be mandated routed out of town?

All this time, and they still aviod adressing various relavent issues. Another cheerleding to mislead and deflect properly informing the public. "

" It is inaccurate to say that there is absolutely no problem unless the injection is done along a fault line, since fault lines can be discovered through survey. Many fault lines go undetected, and injection HAS caused earthquake activity near undetected fault lines. If you doubt this, read the article "A Fluid--Injection Triggered Earthquake Sequence in Ashtabula, Ohio: Implications for Seismogenesis and Hazard in Stable Continental Regions (SCR)"--American Geophysical Union, Fall Meeting 2003, abstract #S21E-0347.

Must be nice to invest in a joint venture where there's no legal liability and where the taxpayer kicks in at least half the cost of entry.

As to the fisherman52 poster, who comes out against the coal folks on the basis of environmental issues, he's no different than the rest of us. The real reason he favors wind turbnes is because he can pull in $10,000 to $15,000 a year on land leases where those huge unsightly behemoths are located. His motivation is all about the money he receives - not the environment. Clean Coal is a direct competitor to wind turbines. Don't you get it?

I'm in favor of drill, drill, drill, now! The USA has plenty of oil to burn until we figure out where to get our future energy needs. With a government as pervasive as ours has become in the last four months, we could be drilling for oil while the government mandates research alternatives. Seems like that's the path we're on now, except Obama forgot to issue the order to drill, drill, drill, now. "

" Lake Nyos is a lake in a crater of a volcano in Cameroon, Africa. To this day a reservoir of magma which lies beneath the lake bubbles up carbon dioxide into the water in huge quantities. The depth and temperature of the water keeps much of this carbon dioxide at the bottom of the lake, allowing it to dissolve naturally or to bubble to the surface.

On August 21 1986, Lake Nyos belched a massive cloud of carbon dioxide after an eruption. The CO2 cloud killed around 1,700 people and 3,500 livestock nearby and injured thousands more.

It's estimated that 1.6 million tonnes of CO2 was released in the event and as CO2 is denser than air, it hugged the ground in a layer thought to be 30 meters deep for quite some time and distance before it dissipated, suffocating humans and animals in its path.

The outgassing also caused large waves that destroyed trees and other vegetation close to the lake. "

NeoCon Academician wrote on Jun 26, 2009 12:14 PM:

" The many disadvantages of this process have far-reaching consequences.

The carbon dioxide gas is compressed into a liquid form and is stored deep under the earths surface, in areas which are capable of holding the gas securely and preventing it from leaking out. Even though care is taken to identify the right areas for storing the gas underground, there is always a likelihood of the gas leaking out.

When that happens, a number of deadly changes can transpire:

a) The leaked carbon dioxide gas which is in the liquid form can mix with ground water. This will make the ground water extremely toxic and unsuitable for human consumption.

b) Gas stored below ocean or aquifer floors can leak out and increase the carbon dioxide content in the lower layers of the ocean or aquifer. This makes it difficult for the flora and fauna thriving near the ocean or aquifer surface to adjust to the changes and as a result, the whole ecosystem is disturbed.

c) Leakage of the carbon dioxide gas from underground reservoirs can lead to the replacement of oxygen gas near the earths surface with carbon dioxide, leading to loss of plant and animal life in the area. "

NeoCon Academician wrote on Jun 26, 2009 12:21 PM:

" Estimates from the Intergovernmental Panel on Climate Change (IPCC) show customers should be prepared to pay as much as 50% to 70% more for their power. A typical coal plant employing carbon capture technology requires between 24% and 50% more energy for every kilowatt-hour produced. "

" gringa - I am willing to sacrifice the aesthetic value of our countryside in exchange for $10,000 or $15,000 for each one of those ugly behemoths I allow in my back yard. That makes a lot more sense to me than sacrificing our children, grandchildren and great grandchildren's health for the Multi-Billion dollar profits that are being made in the Clean Coal Advertising industry. I am much better prepared to stand before my maker and admit I contributed to installing ugly behemoths on his land than I am to look even one of his children in the eye and tell them the decisions I made contributed to their being locked up in their own mind by autism from mercury from burning coal! Or to pay the incarceration expenses caused by the learning disabilities caused by the lead discharged from the cheap Clean Coal Advertising: coal for the profits of the Clean Coal Advertising industry.

No gringa, I don't fly my private jet to my environmentalist speaking engagements! I drive my American made Chevrolet Impala, on the highway it limps by at about 30 miles per gallon.

I don't think of myself as an environmentalist. I am a strong supporter of drilling for new oil supplies where ever they can be found. I also have those nasty smelling oil wells cluttering up my view of the country side. My wife's dad moved from the water flood oil fields of South Central Illinois to work the deep wells of West Texas. I also support the plan that T. Boone Pickens is promoting to convert most of the OTR Trucking industry from imported diesel fuel to American produced compressed natural gas.

The only fuel source you will hear me speaking out against is the Clean Coal Advertising coal. No matter what you do to it and no matter how you say it has been cleaned up, it will still be the filthiest most polluting fuel available.

By the way the trains stopped burning coal because of the pollution that it discharged. The soot was affecting the health of the railroad employees and those living along the train route.

And gringa. the real reason I favor wind and solar and natural gas and bio-fuel and nuclear and even cord wood over Clean Coal Advertising coal is they are all cleaner than filthy coal.

By the way gringa, what exactly is the definition of Clean Coal and how is it different from all the other Dirty Coal that is consumed in all the coal fired generating plants worldwide? "

-------------------------------------

Classification of CS Risks

Air
Human Health
Ecosystems
Geomechanical/Geophysical

Risks to USDW include:

1) THERE ARE NO CURRENT REGULATIONS REGULATING THE PROCESS OF CARBON SEQUESTRATION only PROPOSALS and GUIDELINES

2) The formation of Carbonic Acid. It is formed when CO2 comes into contact with water and acidifies it. It causes naturally occurring metals, like
arsenic to move into water and water sources.

3) Hydrogen Sulfide and nitrous oxide present in CO2 endangers USDW's.

4) Injected CO2 at high pressure (1.88 atmospheres or 27.64 PSI) can induce or open existing fractures in geo-formations leading to increased movement and escape through caprock.

5) Exposure to CO2 causes acute and chronic health effects upon terrestrial mammals and birds.

6) Acute aquatic exposure to CO2 impedes fish repiration.

7) Acute aquatic exposure to CO2 causes decreases in pH (-1 to 14.5, H+ range)to lethal levels for aquatic life.

8) Acute aquatic exposure to CO2 reduces calcification in shelled organisms

9) Acute aquatic exposure to CO2 adversely affects photosynthesis in various aquatic organisms.

1) Sleipner Project - North Sea near Norway

2)SALAH GAS PROJECT - Central Sahara Desert Algeria

3) WEYBURN EOR PROJECT - Beulah, ND
