Product Description
Answering the question of whether operating one or more natural-gas turbines to firm variable wind or solar power would result in increased Nitrous oxide (NOx) and Carbon Dioxide (CO2) emissions compared to full-power steady-state operation of natural-gas turbines, the analysis demonstrates that CO2 emissions reductions are likely to be 75-80% of those presently assumed by policy makers (one-for-one reduction). NOx reduction depends strongly on the type of NOx control and how it is dispatched. For the best system examined, using 20% renewable penetration, the NOx reductions are 30-50% of those expected; in the worst, emissions increased by 2-4 times the expected reductions.
