7000 ft below the city of Decatur, Illinois, population 74,710 people, is a high pressure reservoir which contains 1 million tons of CO2.
From the press release:
"One of the largest carbon sequestration projects in the U.S., the Illinois Basin – Decatur Project (IBDP) has reached its goal of capturing 1 million metric tons of carbon dioxide and injecting it deep underground in the Mount Simon Sandstone formation beneath Decatur, Illinois. The project is designed to demonstrate the feasibility of carbon capture and storage. IBDP director Robert Finley talked about the million-ton milestone with News Bureau physical sciences editor Liz Ahlberg. Finley is director of the Advanced Energy Technology Institute at the Illinois State Geological Survey, part of the Prairie Research Institute at the University of Illinois."
The reservoir has been created to demonstrate the viability of carbon sequestration – capturing large quantities on carbon, to prevent the CO2 from being emitted into the atmosphere.
The University of Illinois scientists responsible for this demonstration project assure us that the reservoir does not pose a safety threat. According to a University of Illinois press release;
“Extensive monitoring takes place during and after injection to be sure the stored CO2 stays in place. Monitoring techniques include using geophysical technology to confirm the position of the CO2 underground and wells to monitor groundwater and soils.
No out-of-bounds health, safety or environmental risks were observed from this properly designed and managed storage site. Appropriate risk mitigation and management plans were an integral part of the overall project planning. Extensive monitoring took place before, during and now after the injection to be sure the CO2 stays in place. The first line of monitoring begins deep below the ground, so we know if any leakage occurs long before any CO2 might reach the surface.”

They’re probably right – when you create a demonstration project, a showpiece for what you hope will become a lucrative business, you want to make sure nothing goes wrong. I’m sure that elaborate precautions have been taken to prevent any possibility of adverse news, in the hope that this reservoir will be the first of many.
However, as the scientists responsible for the project admit, a serious carbon sequestration effort will need to store a lot more than a million tons of CO2. “… One million tons is scalable in its behavior to the 3 million tons that would be emitted annually from a typical medium-sized, coal-fired power plant. …”
If just one of those proposed sequestration projects suffers a major containment breach, say if an earthquake cracks the geological structure, or if a mistake or greed leads to the reservoir being overloaded, the result could be a disaster.
In Africa, in 1986, an abrupt release of an estimated 100,000 – 300,000 tons of CO2 killed 2,500 people up to 25km (15.5 miles) from the source of the release.

A similar release near a major city would kill a sizeable fraction of the city’s population. The region of devestation was comparable to the loss of life which would be caused by a large nuclear explosion – the only reason a lot more people didn’t die, was Lake Nyos is a sparsely inhabited rural region.
The Lake Nyos CO2 release was so deadly, because CO2 is heavier than air – when the huge CO2 cloud boiled out of lake Nyos, it hugged the ground, displacing all breathable air to an elevation 10s of ft above ground level, suffocating almost everyone in its path.
Its not just people and animals which would be affected – car engines would also stall, as the blanket of CO2 choked off the supply of oxygen.
If carbon sequestration becomes commonplace, sooner or later someone will get greedy and careless, and will be careless in their choice of geological reservoir, and / or will overload their geological reservoir to boost their bottom line. And that carelessness will, in my opinion, almost inevitably lead to a catastrophic loss of life.
Is your mother in the room?
She’s in Decatur.
Unfortunately she’s not staying.
Where are you?
I’m taking the day off, come on over.
Hmmm..
What could possibly go wrong?
I remember reading a Scientific American article about an unusual disaster that occurred in Africa. Apparently, there was some sort of thermal inversion in a lake, and a large CO2 concentration built up there. The thermal distribution changed, the carbon dioxide came out of solution, the lake made a huge CO2 burp, and everyone around the shore died from suffocation.
Here, the pressurization is man made. What could go wrong?
What do the people in Decatur have against plants?
I don’t see the point of doing this.
Let me guess who paid for this boondoggle.
All for global warming_____
The ancient Egyptians were similarly crazy and squandered resources on building pyramids for degenerate brother-sister marriage Pharaohs
**Its not just people and animals which would be affected – car engines would also stall**
I suppose if the drivers are all dead the stalling car engines is a good thing.
Our tax money paid for this?
What a colossal waste of dollars.
Remind me to take another route when traveling to Southern Illinois.
Pipe it to my greenhouse.
That was circa 1993 and I remember it. It was in the mainstream news

Did Decatur citizens get a voice in allowing this potential hazard in their community?
That would put the fizz in a lot of sodas and beer.

Decatur is the largest city and the county seat of Macon County in the U.S. state of Illinois. The city was founded in 1829 and is located along the Sangamon River and Lake Decatur in Central Illinois. In 2013 the city population was 74,710.[1]
But they will all die holding the high moral ground and with a clean conscience ...
