Co-ops demonstrate new pollution controls

Stanton, ND, August 22, 2013— The Cooperative Research Network (CRN) and eight Generation and Transmission cooperatives (G&Ts) are partnering with ClearChem LLC on a demonstration of new technology to reduce sulfur dioxide emissions at a plant owned by Great River Energy.   

This test is the third in a series of demonstrations spearheaded by NRECA’s Cooperative Research Network and funded by a group of cooperatives seeking cost-effective environmental control technologies that will enable them to retrofit existing coal-fired plants to meet new federal environmental standards. 

This demonstration will test the effectiveness of ClearChem’s Furnace Sorbent Injection (FSI) of micronized limestone.  Environmental Energy Services, licensed applicator of the ClearChem FSI, is also participating in the demonstration.

Since 1990, cooperatives have reduced both sulfur dioxide and nitrogen oxide emissions by 65 percent nationwide. New air quality standards, including interstate emission reduction initiatives, as well as regional haze requirements, are driving further reductions. 

CRN is testing combinations of emerging and commercial technologies to find methods that can meet new standards affecting a range of coal-combustion emissions, including SOx, NO2, mercury and acid gases. The demonstration is occurring at Great River Energy’s Stanton plant near Bismarck, ND.  CRN has successfully conducted demonstrations of other technologies at San Miguel Electric Cooperative’s San Miguel plant in Texas and Arizona Electric Power Cooperative’s Apache plant in Arizona.

Coal is an important fuel for the nation’s electric co-ops: in 2012 coal accounted for roughly 70 percent of co-op power generation. Member-owned, not-for-profit cooperatives are actively seeking cost-effective technologies to enable our coal fleet to continue to provide affordable electricity to co-op consumer-members across the country.

The National Rural Electric Cooperative Association is the national service organization that represents the nation’s more than 900 private, not-for-profit, consumer-owned electric cooperatives, which provide service to 42 million people in 47 states.
