SOx and NOx emissions reductions from coal fired electric power generation

SOx and NOx emissions

Coal accounted for more than 50% of U.S. electricity generation in 1997, and natural gas and renewables together accounted for 26% of generation. By 2017, coal-fired generation had declined to 30% of electricity generation while generation from natural gas and renewables grew to nearly 50% of electric power industry generation.

New Carbon Capture Pilot Plant in Wisconsin

ALSTOM, The Electric Power Research Institute (EPRI) and We Energies just announced a CO2 capture demonstration power plant in Wisconsin using a chilled ammonia process to remove the CO2 from the flue gas. The plant aims to capture about 90% of the CO2 emitted by the power plant. The size of the power plant is ~1210 MW (electric) [actually 2 x 617 MW]. According to this presentation on the web, ALSTOM clearly is seeking to take the lead on making conventional pc fired plants ready for a carbon constrained environment by retrofitting the plant.
