The Organic Rankine Cycle (ORC) technology operates similarly to a traditional steam turbine but with a key distinction. Instead of water vapor, the ORC system employs a high-molecular-mass organic fluid.
This adjustment leads to superior electric performance within a closed-loop thermodynamic cycle, making it particularly well-suited for distributed generation. The ORC process harnesses waste heat from industrial operations to generate electricity.
In an ORC system, waste heat heats an organic fluid, causing it to vaporize and expand. This vapor then drives a turbine to produce electricity, which can be used on-site or fed into the grid.
The technology converts electric and thermal power from various sources, including renewable resources like biomass, geothermal energy, and solar power, as well as traditional fuels and waste heat from industrial processes, incinerators, engines, and gas turbines.
Unlike conventional Rankine cycles, which use water to generate steam, the ORC system uses organic fluids with higher molecular masses, such as butane, pentane, hexane, and silicon oil.
These fluids have lower boiling points than water, resulting in slower turbine rotation, reduced pressure, and minimized erosion of metal parts and blades. This approach enhances the system's efficiency and longevity while effectively converting waste heat into useful energy.
The key market dynamics that are shaping the global ORC waste heat to power market include:
