How to Deal with Global Warming — Carbon Capture and Sequestration can be an answer

 

British Geological Survey states that carbon capture and sequestration is one of the most effective and realizable technologies in terms of impeding global warming.

In September 10, 2002, Norwegian Statoil company experimentally proved that carbon sequestration is a feasible solution to global warming that has little harm to the environment.

 

According to the Intergovernmental Panel on Climate Change Fourth Assessment Report, it is almost evident that humans cause the recent global warming and that it is increasing in the greatest rate in the past 1,300 years.

 

While numerous organizations such as Greenpeace or World Nature Organization strive to inform people about the rapid progression of global warming, few of them offer specific solutions to impede it.

 

Among the many on-going researches on the solutions to the global warming, the ones on carbon capture and sequestration (CCS) is increasingly acknowledged worldwide.

To experimentally examine the efficiency of CCS, Norwegian Statoil company sifted out 9% CO2 in methane, and transferred it into porous sanstone 800 meters in depth. It was a success. Using this method, the firm could put 5 million tones of CO2 into the deep layer beneath the sandstone.

 

Dr. Chadwick from British Geological Survey asserted that CCS is safe and technically feasible, and has very little environmental downside.

 

CCS is already applied to several coal power plants. Namely, on October 3, 2014, the provincial utility SaskPower built Boundary Dam, a 110 megawatt coal power, as well as CCS plant in Saskatchewan. The Dam sequesters 90 percent of carbon dioxide released during the production of electricity.

 

Yet, CCS’s major drawback is that it is costly. Building a unit of CCS plant costs $800 million. In addition, the sequestration uses up 21 percent of the coal plant’s power output.

 

Nonetheless, environmentalists have continuously developed CCS and are now making progress. The chemical engineer Gary Rochelle and the president of the carbon sequestration project Michael Monea insisted that the next carbon sequestration plant can be built costing 20% to 30% less.

 

Although CCS is not yet complete, many scientists claim that it is still prospective and argue that it should be improved further in the future.
