ORC Waste Heat to Power Market Size, Growth & Forecast 2032

The global push toward energy efficiency and sustainability has significantly increased the demand for innovative technologies that minimize energy wastage. One such technology gaining traction is Organic Rankine Cycle (ORC) waste heat to power systems. These systems convert low- to medium-temperature waste heat into usable electricity, offering industries an opportunity to improve energy efficiency while reducing carbon emissions.

The global ORC waste heat to power market size was valued at USD 932.5 million in 2024 and is projected to grow from USD 987.3 million in 2025 to USD 1,503.2 million by 2032, exhibiting a CAGR of 6.19% over the forecast period. This growth is supported by the expansion of energy-intensive industries seeking efficient waste heat recovery solutions amid rising energy costs.

What is ORC Waste Heat to Power?

Organic Rankine Cycle (ORC) technology is a thermodynamic process similar to the traditional steam Rankine cycle but uses organic fluids with lower boiling points. This allows it to generate power from low-temperature heat sources such as:

Industrial exhaust gases
Geothermal heat
Biomass combustion
Engine exhaust systems

ORC systems are particularly suitable for industries where conventional steam turbines are inefficient due to low heat temperatures.
