RWE’s 450 MW IGCC/CCS project—Status and outlook

Abstract

Abstract Since mid-2006, RWE Power has been planning the construction of a coal-based demonstration power plant with carbon capture, transport and storage. A combined-cycle gas turbine plant with integrated coal gasification (IGCC) was chosen as the power plant technology to be used. The use of a modern gas turbine of the F class enables the plant to achieve a gross electric capacity of approx. 450MW. The separated CO 2 is to be stored safely over the long term in deep saline aquifers. The first grid connection is due to take place at the end of 2014/start of 2015. As regards the power plant, a feasibility study was conducted to analyze and evaluate the technologies available in the process chain, decide on a technical concept, and establish the technical and economic parameters of the process. As far as CO 2 transport & storage is concerned, regional screening is about to be completed and the potential storage sites are being evaluated in-depth with respect to seismic data interpretation, lithology, and structure. This presentation will outline key findings and results of this phase for both the power plant and transport & storage and present the next steps to be taken in the execution of the project. In light of a market situation characterized by high capacity utilization of potential contractors and an extraordinary rise in investment costs this aspect is currently very important. Another basic prerequisite needed for the project to proceed according to schedule is the establishment of a European and national regulatory framework for carbon transport and storage by mid-2009.
