Further improvements in gas turbine technology would boost theadoption of IGCC technology. NTPC’s IGCC programme aims to set up a 100 MWe netcapacity IGCC demo plant. The mainstay CCT ideally suited to Indian energy needsmay be a totally new combination of present approaches, according to Mr. Dubey.Mr. Dubey’s presentation is in Annex V.12
