Clinton Crackel, Co-Founder, Nuclear Fuels Reprocessing Coalition, Executive Consultant to Quantum Dynamic Sciences, Inc.: Since the 2006 test, the technology has improved so that now it is possible to achieve a CO2 stack outlet efficiency of 98% or better. Assuming an efficiency rate of 98% without a scrubber, the estimated lifecycle greenhouse gas emission of a coal-fired power plant would be reduced from 1050 gCO2/kWh to 21 gCO2/kWh. This value is lower than the estimated value of 32 gCO2/kWh for a solar PV unit made of polycrystalline silicon.
