I’m often asked: what is the cleanest coal-fired power plant in the world? I am also asked: how “clean” is clean coal?
If emissions levels from a gas-fired combined cycle plant are the measure of “clean,” then there are emissions control technologies available today for coal-fired plants that can produce comparable emissions. To be sure, low emissions from coal-fired plants isn’t a technology problem, it’s a political problem.
Unit 2 at J-POWER’s Isogo Thermal Power Station is an exemplar for low emission coal-fired plants. The second unit at the plant entered commercial service in July 2009, so the plant has been in operation for about 18 months. The 600-MW ultrasupercritical unit 2 joins an earlier, similar plant built in 2002. Together, these two new plants replaced 1960s-vintage coal-fired plants and doubled power generation from the small project site.…
