Experience Curves for Environmental Technology and Their Relationship to Government Actions

We seek to improve the ability of integrated assessment models (IA) to incorporate changes in CO2 capture and sequestration (CCS) technology cost and performance over time. This paper presents results of new research that examines past experience in controlling other major power plant emissions that might serve as a reasonable guide to future rates of technological progress in CCS systems. In particular, we focus on U.S. and worldwide experience with sulfur dioxide (SO2) and nitrogen oxide (NOx) control technologies over the past 30 years.
