Diagnostic Monitoring of Biogeochemical Interactions of a Shallow Aquifer in Response to a CO2 Leak
A grant to watch -

EPA Grant Number: R834503Title: Diagnostic Monitoring of Biogeochemical Interactions of a Shallow Aquifer in Response to a CO2 Leak
Institution: Columbia University in the City of New York
Project Period: September 1, 2009 through August 31, 2012
Project Amount: $899,882
RFA: Integrated Design, Modeling, and Monitoring of Geologic Sequestration of Anthropogenic Carbon Dioxide to Safeguard Sources of Drinking Water (2009)
Research Category: Drinking Water
Objective:
CO2 injection into deep geological formations capped by low permeability formations is one of the most promising alternatives for mitigation of anthropogenic climate change. Several deep pilot and demonstration projects are underway. However, the upward leakage of CO2 or mobilized brines through the cap rock could lead to vulnerability of shallow, overlying drinking water aquifers. Elevated levels of dissolved CO2 might affect microbial community dynamics and mobilize natural-radioisotopes, metals, and other non-potable elements and compounds. The proposed research will investigate a shallow potable water aquifer system in sand/clay sequences of the Newark Basin group using laboratory and in situ methods and test how it would respond to a high-level CO2 condition caused by a hypothetical leakage of CO2 from deep injection reservoirs. In particular, we will (1) determine metal release rates as a function of pCO2 and pH under laboratory and field conditions, (2) measure microbial community dynamics as a function of increased acidity and dissolved metal concentrations, (3) determine the role and persistence of microbial communities in the mobilization or immobilization of metallic elements, (4) measure in situ/ex situ mobilization and immobilization of metals under high-level CO2 conditions, (5) determine the extent to which leaked CO2 is geochemically trapped in the aquifer, and (6) develop diagnostic monitoring techniques to advance assessments of groundwater contamination risks and water quality deterioration due to a CO2 leakage event.
Approach:
We will conduct a series of geochemical and microbiological laboratory experiments using rock and water samples extracted from a shallow aquifer. We will also add CO2 (pCO2 up to 5 bars) to local groundwater, re-inject it into the aquifer, and then sample and monitor the elevated-CO2 aquifer water in a series of in situ push-pull and forced-gradient experiments.
Expected Results:
Results from these coupled laboratory and field experiments will greatly improve our understanding of the geochemical and microbiological reactions under low pH - high CO2 stress. We anticipate that this research will: (1) provide criteria for site selection for geological CO2 sequestration, (2) identify aquifers that would be least vulnerable to risks of CO2 leakage and subsequent contamination, and (3) provide a small number of diagnostic testing parameters that may be used in other potable aquifer systems associated with deep CO2 injection.

More CO2 storage than previously thought for Indiana, Kentucky, Michigan and Ohio
Despite the fact that CCS is extremely expensive, risky, and hard to monitor and is very controversial --- the studies and push for CCS continues. It simpley makes no sense to me.....now we find a report from December 2009 that says we can store about 74% more! NO THANK YOU!
As a reminder - In Ohio, a large portion of the Mt Simon Sandstone sits below one of the largest fresh water aquifers in the world - our most precious resource. States are running out of water...
Much of the proposed CO2 to be used for CCS in the midwest comes from ethanol plants..... in our area we had a great harvest last year with the extra CO2 - if CCS is so "safe" why are there no plans to inject it under the cities that produce the bulk of it?
I do remember reading a study done in Ohio that said it would not happen in Columbus, Ohio because "it was too urban and densely populated".

The total storage capacity for the region, calculated, using efficiency factors of 0.01 and 0.04, is estimated to be 37.8 and 151.2 billion metric tons of CO2 respectively. This is approximately 74 percent higher than the values of 21.7 and 86.9 billion metric tons of CO2 estimated by the MRCSP for the capacity of the Mount Simon Sandstone in the states of Indiana, Kentucky, Michigan, and Ohio.

Scientists Target East Coast Rocks for CO2 Storage
January 4, 2010
Power Plants Might Pipe Emissions Under Seabed
Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources. A study this week in the Proceedings of the National Academy of Sciences outlines formations on land as well as offshore, where scientists from Columbia University's Lamont-Doherty Earth Observatory say the best potential sites may lie.
Underground burial, or sequestration, of globe-warming carbon dioxide is the subject of increasing study across the country. But up till now, research in New York has focused on inland sites where plants might send power-plant emissions into shale, a sedimentary rock that underlies much of the state. Similarly, a proposed coal-fired plant in Linden, N.J. would pump liquefied CO2 offshore into sedimentary sandstone. The idea is controversial because of fears that CO2 might leak. By contrast, the new study targets basalt, an igneous rock, which the scientists say has significant advantages.

From our Friends in France - TOTAL CO2 stocking - France - Petition against CCS for European Parliament
TOTAL Cie is planning, for the first time in France, the stocking of 150 000 tonnes of CO2 over the two following years in an inhabited and cultivated city called Jurançon (in the Pyrenees). This pilot project is to be largely industrialized and globalized over the world. This project is sold as "environmental"! But this project is absolutely NOT an environmental one ! And TOTAL will be disengaged from any responsibility in 2013!
Clearly, the capture and stocking of CO2 has three major interests in the eyes of the industrialists :
1. Not being taxed on the emissions of greenhouse gases due to be buried
2. Getting rid of such waste under the guise of environmental projects
3. As a bonus, gain maximum financial benefits from the commercialization of these patents
Alongside these issues, the security of the population, and the richness of local environment, have little value!
A petition is available at http://co2.jurancon.blog.free.fr designed to the European Parliament (Your signature is important because social acceptance is central to the project, and Total has done everything not to communicate on the subject locally) - NOTE - the site it links to is in FRENCH
Let's protect our environment locally and globally, but more importantly, let's do someting against such nonesense projects! Because, once again, this project is anything but "environmental"! (Online explanatory articles).

Indiana bill would give CO2 pipeline firms right to take private land
By Chris O'Malley, The IBJ
comally@ibj.com
A bill filed in the Indiana General Assembly would give companies building pipelines to carry carbon dioxide the right to take private land in their path.
A consumer group opposing Senate Bill 115 argues the measure is yet another concession to the developer of a coal-to-methane plant proposed in Rockport, as well as to coal-fired electric utilities that may opt to transport CO2 to underground storage sites.
The measure declares that the transportation of CO2 by pipeline "is declared to be a public use and service, in the public interest, and a benefit to the welfare of Indiana," citing its potential to reduce carbon emissions and to promote economic development.
"Granting eminent domain to a private entity is reason enough, we think, to oppose this bill," said Kerwin Olson, program director for Indianapolis-based Citizens Action Coalition.
The group said the measure is to benefit Indiana Gasification, which in 2006 proposed building a $1.5 billion plant in Spencer County to convert high-sulfur coal to gas. Utilities could use the gas for heating and to generate electricity.

Exploratory study of some potential environmental impacts of CO2 sequestration in unmineable coal seams
From the web site - http://inderscience.metapress.com/app/home/contribution.asp?referrer=parent&backto=issue,10,14;journal,28,88;linkingpublicationresults,1:110851,1

An initial investigation into the potential environmental impacts of CO2 sequestration in unmineable coal seams has been conducted, focusing on changes in the produced water during enhanced coalbed methane (ECBM) production, using a CO2 injection process (CO2-ECBM). A high volatile bituminous coal, Pittsburgh No. 8, was reacted with synthetic produced water and gaseous carbon dioxide at 40C and 50 bar to evaluate the potential for mobilisation of toxic metals during CO2-ECBM/sequestration. Microscopic and X-ray diffraction analysis of the post-reaction coal samples clearly show evidence of chemical reaction and chemical analysis of the synthetic produced water shows substantial changes in composition. These results suggest that changes to the produced water chemistry and the potential for mobilising toxic trace elements from coal beds are important factors to be considered when evaluating deep, unmineable coal seams for CO2 sequestration.
