Cost of Carbon Capture for Coal

One issue with the conventional thinking about the high cost of carbon capture with coal-fired power plants is the thinking that it is necessary to capture upwards of 85-90% of CO2 emissions.

This is not the case, and the industry should be rethinking such a requirement as it places an inordinate cost burden on the process.

Since natural gas fired plants are typically considered as being "clean and green", it would seem that the more appropriate target for carbon capture would be to achieve CO2 emissions that are the equivalent to natural gas combined cycle on a lb per kWh basis.

Not only is the cost of removal greatly reduced, especially if pre-combustion removal is employed as is made possible in an Integrated Gasification Combined Cycle (IGCC) plant, but also the cost of transport and sequestration is proportionately reduced.

About a year ago, we posted a blog on the subject which could be read at: http://gasification-igcc.blogspot.com/2007/10/natural-gas ...
