Abstract When implementing energy storage systems, different forms of energy usually have to be converted into each other. For example, the battery voltage is often not high enough to be used for the conversion of direct current into alternating current. Therefore, inverters and converters are necessary. This chapter explains these power

In this chapter, some aspects of steam cycles combined to modular HTR as heat source are explained. On the basis of a simplified flow sheet, the process and the main thermodynamic aspects are explained. Simple estimations deliver already the practical result of a net efficiency of 40% applying today-established parameters of the steam cycle with ...
