Organic Rankine Cycle

What is ORC?

organic rankine cycle An Organic Rankine Cycle (ORC) converts heat into electricity. This technology is based on the Rankine principle that has been successfully implemented in projects all over the world. The Organic Rankine Cycle is a thermodynamic process where heat is converted into power, which drives a turbine. A working  fluid is vaporised and expanded in a vapour turbine that drives a generator, which then produces electricity. The working fluid is an organic fluid with a boiling point lower than water and enables heat recovery from low temperature sources.

Applications of ORC

ORC technology is particularly suitable for every organisation that disposes of residual heat of at least 90°C from their production processes. Upgrade Energy ORC systems can produce electricity from a range of sources:

  • Industrial manufacturers (metal, molding, construction materials, food productions, etc.)
  • Concentrated Solar Power systems
  • Heat from industrial processes, reciprocating engines and gas turbines
  • Biomass combustion
  • Geothermal resources with medium to low temperature

Why ORC?

The Organic Rankine Cycle is the perfect technology to convert low temperature residual heat into useful electricity. Heat that would otherwise go to waste, and would either be damaging to our atmosphere and environment, or costly to manage, is used as a free source of energy!

Your company can thus efficiently use energy that is free and already available on site from your production processes, and also simultaneously reduce the amount of waste being released into the atmosphere.


  • Proven technology
  • High efficiency
  • Long life of the plant
  • Simple maintenance procedure
  • Reduction of CO2 emissions
  • Modular design
  • Easy integration

Upgrade Energy brings ORC systems to your company

The succesful installation and operation of a number of ORC systems has provided Upgrade Energy with the expertise to correctly dimension and implement this technology in your process. Important factors are flow, temperature and acid dew point of the flue gasses.
