Company fuel cells have a naturally high concentration of CO2 in their fuel stream — about 75 percent concentration of CO2, compared to 10 percent or so from a typical coal
plant emissions stream.
Current technology relies mostly on amines or carbonates to capture the carbon dioxide from the power
plant emission stream.

There also will be additional tests at Pacific Northwest National Laboratory to test impurities that can exist in actual coal -
plant emissions as opposed to simulated gas
streams in a lab.
By reducing carbon
emissions through renewable fuel sources, we can reduce environmental degradation; by
planting campuses with native trees, shrubs, groundcover, and grasses, we can reduce the use of fertilizers and pesticides that pollute our

The report's authors point out that recent increases in
emissions from the EU's coal - fired power sector are not due to more coal - fuelled facilities coming on
stream, but rather because existing
plants are running at full capacity.
But whether sequestration is a viable means of curbing
plant emissions remains to be seen; cost is an important factor in implementing the strategy because carbon dioxide has to be separated from a power
plant's gas
stream and compressed before it can be injected into the ground.
