Data sorted by year of cost information as published; no full set of data available for installations in China. Overnight costs include owner’s, EPC and contingency costs, but not IDC. A 15% contingency based on EPC cost is added for unforeseen technical or regulatory difficulties for CCS cases, compared to a 5% contingency applied for non‐CCS cases. IDC is included in LCOE calculations. Fuel price assumptions differ between regions. IGCC reference plant data are not provided in the NZEC (2009) publication.
© OECD/IEA 2011 Cost and Performance of Carbon Dioxide Capture from Power Generation All reviewed studies apart from one evaluate pre‐combustion CO 2 capture from IGCC plants that operate on bituminous coals. Gasifier technologies by ConocoPhillips (CoP), General Electric (GE), Shell and the Chinese Thermal Power Research Institute (TPRI) are analysed. Average published capacity factors are 81% for the cases shown; CO 2 capture rates are 88%. Net power outputs including CO 2 capture range from 482 MW to 730 MW across OECD regions, at an average net efficiency of 33.1% (LHV). The impact of adding pre‐combustion capture to an IGCC reference plant without CO 2 capture is illustrated in Figure 3. Net efficiency penalties between 5.5 and 11.4 percentage points (LHV) are estimated for precombustion CO 2 capture in OECD regions, which is on average a 20% reduction in efficiency. No IGCC reference plant data are provided in the case study on pre‐combustion CO 2 capture in China (NZEC, 2009). By adding CO 2 capture, overnight costs updated to 2010 cost levels increase on average by USD 1 128/kW compared to an IGCC reference case. However, the increase varies substantially by a factor of more than two between USD 609/kW and USD 1 580/kW. 9 The relative (percentage‐wise) increase of overnight costs is more stable across studies. Overnight costs increase by on average 44% compared to an IGCC reference power plant when adding CO 2 capture. This trend appears comparably robust across the range of gasifier technologies and between the United States and the European Union. LCOE figures follow a similar pattern. In OECD regions LCOE increases on average by USD 29/MWh relative to an IGCC reference plant, but varies between USD 19/MWh and USD 39/MWh. The relative increase of LCOE compared to the LCOE of the reference plant is on average 39%. Costs of CO 2 avoided are on average USD 43/tCO 2 if an IGCC reference plant is used, but vary between USD 26/tCO 2 and USD 62/tCO 2 for OECD regions across study cases. If a pulverised coal power plant reference case is used, average costs of CO 2 avoided rise to USD 55/tCO 2 . The cost of CO 2 avoided in China is estimated USD 32/tCO 2 relative to a Chinese pulverised coal power plant, or about half of the costs in OECD regions. Table 6 illustrates the influence of specific fuel types. However, only a single data point is available for sub‐bituminous and lignite‐fired installations, which is insufficient for drawing conclusions regarding technology competitiveness compared to bituminous coal‐fired options. Page | 29 9 As stated by the authors in a follow‐up publication (MIT, 2009), IGCC cost estimates published in MIT (2007) might have been too optimistic.
