Sind Kombi-Kraftwerke mit integrierter Kohlevergasung wettbewerbsfähig?

From investigations into improvements that are feasible already today for integrated coal gasification combined-cycle power plants net plant efficiencies reach 51,5 % (with reference to the calorific value), not considering the calorific value of the separated elemental sulfur. Specific investment costs (plant supply price) have been determined with US-$ 1100/kW. With the given market conditions, it results that the IGCC power plant is in a posiition to compete with a modern hard coal-fired steam power plant. Detailed investigations show a further efficiency potential of about 56 % under considerations of futur developments
