Investments in three coal-fired power generation technologies are valued using the "real options" valuation methodology in an uncertain carbon dioxide (CO2) price environment. The technologies evaluated are pulverized coal (PC), integrated coal gasification combined cycle (baseline IGCC), and IGCC with pre-investments that make future retrofit for CO2 capture less expensive (pre-investment IGCC...
In this paper, effects of the operating pressure on ash formation reported in the open literature have been reviewed. In particular, the recent significant advances achieved at the Cooperative Research Centre for Coal in Sustainable Development (CCSD) in Australia are highlighted. The operating pressure significantly influences the size and the chemistry of ash generated through its effects on ...
I am pleased to be here today to share with you our views about the benefits that Integrated Gasification Combined Cycle (IGCC) technology can deliver. IGCC can cost effectively produce power from solid fuels, such as coal, with substantial environmental benefits over other coal power generation technologies. If IGCC is adopted as the preferred coal based power generation technology, it will he...
How much should governments subsidize the development of new clean technologies? We use patent citation data to investigate the relative intensity of knowledge spillovers in clean and dirty technologies in four technological fields: energy production, automobiles, fuel and lighting. We find that clean patents receive on average 43% more citations than dirty patents. Clean patents are also cited...
a r t i c l e i n f o JEL classification: C14 D24 O13 O44 Q53 Q56 Keywords: Shadow price Emissions trading Directional distance function Marginal abatement cost Coal power plant Shadow prices, also termed marginal abatement costs, provide valuable guidelines to support environmental regulatory policies for CO 2 , SO 2 and NO x , the key contributors to climate change. This paper complements the...
Pulverized Wyoming subbituminous coal was beneficiated by low-pH oil agglomerationat CONSOL to prepare the coal for direct liquefaction. Conventional cleaning is not veryeffective in cleaning this coal; for example, conventional oil agglomeration only givesabout 20% ash rejection. To improve ash rejection, the coal-water slurry was acidifiedto a pH of about 0.5. Oil agglomeratio...
2 Research method Different methods of coal processing into fuel [1, 6, 12] usually require its intensive comminution. Such situation needs the creation of new technologies for coal micronization [4, 11, 17] that enlarge specific surface of coal micro particles what finally intensifies burning process of such coal dust. Some interesting effects of water-coal mixture ensure waterjetting technolo...
