High efficiency of HoSt Steam Cycle

The electrical efficiency of a HoSt steam cycle is much higher than an ORC (Organic Rankine Cycle). The difference increases significantly for installations above 1 MWe. Up to 40% more electricity can be generated by a steam cycle due to:

  • 30% higher cycle efficiency.
  • Lower parasitic electrical consumption. The thermal oil pump of an ORC consumes up to 10% of the generated electricity.
  • Higher boiler efficiency due to a lower flue gas flow in combination with a lower stack temperature.

HoSt has the highest steam cycle efficiency when compared with other suppliers due to:

  • High pressure and temperature steam in combination with an efficient multi stage turbine and an optimized process integration.
  • Low stack losses due to a low flue gas flow, achieved by an innovative combustion technology with a low oxygen surplus.
  • Low parasitic energy consumption due to low pressure losses in the system.
