Siemens' Organic Rankine Cycle generates electricity from waste heat
Siemens Energy is expanding its product portfolio to include a new technical solution for generating electricity from waste heat. The Siemens Organic Rankine Cycle (ORC) module enables owners/operators of industrial plants to generate power from waste heat with temperatures of around 300° Celsius.
The ORC process uses an organic working medium obtained from the group of silicone oils with a substantially lower vaporization enthalpy than water. The vaporized oil is used to drive a steam turbine. The ORC modules currently offered by Siemens have a capacity of up to 2 megawatts (MW), but the company is planning to expand the ORC product portfolio to higher capacities over the medium term.
