The warmist German klimaretter.info site has a piece about sequestraton of carbon dioxide, which reports that Swedish power company Vattenfalls plans have a CCS plant near Berlin ready by 2015.
The plant would remove CO2 from Vattenfall’s brown coal power plant and pump it into the earth for high-pressure underground storage. But an expert geological assessment shows that could lead to problems. According to klimaretter.info:
Storing carbon dioxide underground could however have negative impacts beyond Brandenburg. A geological expert assessment for the community of Barnim-Oderbruch made available to klimaretter.info states that because of the overpressure in the bedrock strata, a salinisation of groundwater has to be expected within a radius of 100 km from the injection borehole. That would affect Mecklenburg Western Pommerania and Poland.
That means the entire Berlin metropolitan area would be impacted. Geology expert Ralf Krupp studied the underground geology in the area and concludes that the ground structure may not be able to securely store the CO2 because the 20-meter salt layer is not thick enough, and so fears that the high pressure could lead salt water carrying strata to mix in with drinking water – causing it to become saline. Kilmaretter also writes:
Especially problematic for Krupp is that saltwater probably is laden with heavy metals. ‘This could be an acute hazard for many water utilities,’ the geologist descríbes.”
In the meantime Vattenfalls calls such scenarios “purely speculative” and that there a number of technical factors that have to be considered. Water utility companies, however, find the scenarios plausible and not without risk.
In the meantime, the uncertainty is already having a powerful impact on public opinion. Activist and cititens groups are already mobilising to stop the CCS technology from being employed not only near Berlin, but at a number of locations throughout Germany. So add another technology that is too risky to be used – along with nuclear power, GMO’s, high speed trains, coal power plants, shale gas, oil, internal combustion engines, bottled water, fireplaces, toilets…
Reading up on CCS technology, I find that it involves a lot work (consumption of energy) and will provide no benefit. Seems to be yet another superstition-driven folly. Watch this Alberta video on how it works: http://www.youtube.com/watch?v=R0i6dhEPSwU.
