CCS success: Notes from day two of the Regional Carbon Sequestration Conference

This is the second 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.
For those who might question the substance behind CCS, I have one thing to say: You should have come to Pittsburgh.
On day two of the Regional Carbon Sequestration Partnerships Annual Review Meeting, more than a dozen researchers and government officials presented scores of charts, maps, photos and numbers detailing the latest stages of underground sequestration projects. The overriding message? CCS is working.
Across the country, scientists are injecting hundreds of tons of carbon dioxide (CO2) into the ground to test the long-term storage of the greenhouse gas.
Among the many factors researchers are weighing: How much pressure can the ground tolerate? How would earthquakes affect underground storage? How much ground would be needed to store CO2 generated by a coal plant year after year?
Findings presented Tuesday on three projects show the promise of underground carbon sequestration:
1. Based on results of CO2 injection into coal seams in the Williston Basin, researchers have determined that lignite coal seams are an attractive option for storage. In fact, a senior adviser at the Energy and Environment Research Center (EERC) at the University of North Dakota noted that researchers have concluded that there exists 100 years worth of CO2 storage for a 500 megawatt power plant in the region.
2. James Sorenson, a senior research manager at EERC reported continued success from the Plains CO2 Reduction Partnership’s “Huff and Puff” project, which has been pumping CO2 into an oil reservoir about 8,000 feet deep in Northwest North Dakota. Oil fields in the region, Sorenson believes, are “the lowest-hanging fruit in regard to CO2 injection opportunities.”
3. University of Texas research scientist Susan Hovorka told the Factuality team that the Gulf Coast is home to the largest volume of underground sequestration of CO2 in the U.S., noting that one million tons of CO2 has been safely pumped into old oil wells in Mississippi in the last 15 months.
We’ve seen so much progress on CCS in the last day—and there's still plenty more to come from the conference. Stay tuned.
