2008 Conference Paper Synopsis: The paper briefly describes the technology of  conventional IGCCs for electricity generation and shows how such “precombustion plants” need to be modified to capture CO2. The main difference is that the raw gas from the gasifier has to be treated to produce a fuel gas containing more than 90% hydrogen. This adds to the complexity of the plant. But the main reason why the large scale construction of such plants is unlikely in the near future is the absence of a large domestic and industrial market for hydrogen. The paper therefore advocates the production of substitute natural gas, with CO2 capture, as being a more realistic option which can use the existing infrastructure
