Terrestrial sequestration: Notes from the Regional Carbon Sequestration Conference

This is the first in a series of posts from ACCCE’s National Communications Director, Steve Gates, who is attending the Regional Carbon Sequestration Conference underway in Pittsburgh, Penn.
Whether you’ve heard it here or elsewhere, carbon capture and sequestration, or CCS, has become a real part of the climate change conversation.
And while we support technology initiatives to safely capture and store carbon dioxide (CO2) from coal-based power plants, such as American Electric Power’s Mountaineer plant in West Virginia, we realize that sequestering CO2 into geological formations isn’t the only way to permanently store these emissions.
In fact, yesterday during the first day of the Regional Carbon Sequestration Partnership’s Annual Review in Pittsburgh, we heard from researchers who offered updates on carbon sequestration projects of a different kind: using the power of Mother Nature —wetlands, forests and grasslands—to absorb huge volumes of CO2.
Edward N. Steadman represented the Plains CO2 Reduction (PCOR) Partnership.
Among the most interesting projects is the Plains CO2 Reduction Partnership (PCOR), which has explored revised land management practices to preserve wetlands across the upper Midwest. PCOR has partnered with Ducks Unlimited, a conservation group that seeks to protect waterfowl. The science behind the project, according to PCOR Project Manager Edward Steadman is that revitalized wetlands naturally sequester CO2 while providing a renewed habitat for animals.
Another group also exploring the potential for wetlands is the Midwest Regional Carbon Sequestration Partnership (MRCSP). In Maryland, federal agencies are spearheading an effort to restore up to 20,000 acres of tidal marsh in the Blackwater National Wildlife Refuge. Researchers associated with MRCSP are weighing how that restoration might help in sequestrating carbon, said David A. Ball, a program manager at Battelle.
In the West, forests are more abundant than wetlands. So the West Coast Regional Carbon Sequestration Partnership, or WESTCARB, is researching how growing forests might reduce our carbon footprint. John Kadyszewski, speaking on behalf WESTCARB, opened eyes when he put up a chart indicating that an acre of a 100-year pine-fir forest had the potential to remove 400 tons of CO2 per acre.
Creating the technology to measure the results of terrestrial carbon sequestration has been another challenge, according to numerous presenters. But it’s a challenge they are working to overcome.
These efforts are highly encouraging, and we look forward to passing on more developments on carbon sequestration this week. Much more from Pittsburgh to come.
