Abstract: This paper appraises the current development status of the 700°C steam power plant under consideration of process optimisation as well as design aspects of the steam turbine and steam generator. The results for a compact arrangement of the steam turbine and steam generator are also presented. Based on a cycle analysis, a net efficiency between 49.3% and 51.4% can be achieved with the 700°C steam power plant – depending on the implementation and based on an inland plant site. No competing development activities for the 700°C steam power plant are known from the USA or Japan.
