** Vincent Janssen Steenberg suggests the following soundtrack for this article: “Breathe” – The Prodigy **
I had dinner this week with three engineers. It turned out that two of them were closely involved in a subject that is currently being heavily debated—the storage of CO2 (also known as CCS—Carbon, Capture, and Storage).
‘That will mean big business for the plastics industry,’ one of the engineers remarked. He noticed me raise my eyebrows and added: ‘Miles of pipeline, gigantic storage tanks 80 meters in diameter—all made of plastic.’
Is there any research being conducted on the exchange of chemicals contained in the plastic and the CO2 that is being stored under high pressure? It is now clear that when wine is bottled in plastic, it is affected by the chemicals in the plastic to such a degree that one can taste the difference within six months. When that is the case, surely there will be a chemical reaction between the plastic and the CO2?
The engineer looked at me in surprise. No. According to him this issue is not being investigated.
Currently, the European Union is expediting the introduction of a bill that will allow CO2 storage under the North Sea. Can you imagine that? As we slowly but surely understand that plastic waste has a devastating effect on our oceans, what do we do? We lay down plastic pipelines to pump CO2 into empty oil fields without really understanding what the outcome of this might be.
Will the plastic remain intact (considering the pressure at greater sea depths); and what are the possible effects of the CO2 from within the pipelines? What type of plastic is going to be used? Doesn’t it release chemicals itself?
So many questions that are not even considered …
Why is money even invested in this project? The energy problem is only exacerbated, since in order to store CO2 a factory needs 22-42% more fuel than usual. When a power plant stores its own CO2, the cost of energy increases by 42% to 81%. In addition, the capital expenditure of such a plant will increase from 44% to 87%.
One of the Dutch political parties—D66, who have a chance to be part of a coalition—wants the government to help finance the development of storage techniques. While the same party says it wants to cut costs. This does not come as a surprise to me … the chairman of this party’s Permanente Programmacommissie (Permanent Program Commission) is the former vice-president of Shell Russia, Senior Legal Counsel at Shell International, director of the legal department at Shell Pernis, and corporate lawyer for Shell International.
They also want to construct storage for Shell under Barendrecht, Zuid-Holland (a municipality with a population of some 46,000 people). Research has shown that this is the most logical location. That ‘there is no risk of exceeding the legal standards. For some limited issues exceeding the guidelines of the so-called group risk, it has been reported that they can be managed by additional measures. This overrunning will only occur in the pipeline near Shell Pernis.’
…
People are too easily prone to say that CO2 is harmless. ‘It’s in the air we breathe.’ is the most frequently heard argument in support of its harmlessness.
Forget it.
In normal circumstances the density of CO2 is 1.5 times higher than that of air. It displaces the oxygen in air. I quote the WMO’s (World Meteorological Organization) and UNEP (United Nations Environment Programme) Intergovernmental Panel on Climate Change concerning CCS:
‘At normal conditions, the atmospheric concentration of CO2 is 0.037%, a non-toxic amount. Most people with normal cardiovascular, pulmonary-respiratory and neurological functions can tolerate exposure of up to 0.5-1.5% CO2 for one to several hours without harm.
Higher concentrations or exposures of longer duration are hazardous—either by reducing the concentration of oxygen in the air to below the 16% level required to sustain human life, or by entering the body, especially the bloodstream, and/or altering the amount of air taken in during breathing […]
Longer exposure, even to less than 1% concentration, may significantly affect health. Noticeable effects occur above this level, particularly changes in respiration and blood pH level that can lead to increased heart rate, discomfort, nausea and unconsciousness […]
Acute exposure to CO2 concentrations at or above 3% may significantly affect the health of the general population. Hearing loss and visual disturbances occur above 3% CO2 . Healthy young adults exposed to more than 3% CO2 during exercise experience adverse symptoms, including laboured breathing, headache, impaired vision and mental confusion. CO2 acts as an asphyxiant in the range 7-10% and can be fatal at this concentration; at concentrations above 20%, death can occur in 20 to 30 minutes […]
Health risks to the population could therefore occur if a release of CO2 were to produce:
• relatively low ambient concentrations of CO2 for prolonged periods;
• or intermediate concentrations of CO2 in relatively anoxic environments;
• or high concentrations of CO2.’
Or, as one of the engineers commented during our dinner: ‘Well you don’t want a CO2 cloud passing over the town. We all suffocate in that scenario.’ Adding… ‘But the chance that something goes awry is negligible.’
The same was said for the Titanic.
