Syngas Lowers the Carbon Price for Profitable Coal Gasification"
Adam Newcomer and Jay Apt
Integrated gasification combined cycle (IGCC) electric power generation
carbon capture and sequestration have desirable environmental qualities,
but are not
profitable when the carbon dioxide price is less than approximately $50
per metric ton.
We examine whether an IGCC facility that operates its gasifier
continuously but stores
the syngas and produces electricity only when daily prices are high may be
significantly lower CO2 prices. Using a probabilistic analysis, we have
plant-level return on investment (ROI) and the value of syngas storage for
facilities located in the US Midwest using a range of storage
configurations. Adding a
second turbine to use the stored syngas to generate electricity at peak
implementing 12 hours of above ground high pressure syngas storage
increases the ROI and net present value. Storage lowers the carbon price
IGCC enters the US generation mix by approximately 25%.
