Heat-to-Power Systems Market Definition

The heat-to-power systems market is a type of technology that transforms waste heat produced by industrial and energy processes into electricity. These systems work at a low to high temperature using solutions like Organic Rankine Cycle (ORC), Steam Rankine Cycle, Thermoelectric Generators and Kalina Cycle. The sources of heat that they use are in the form of industrial waste heat, engine and turbine exhaust, geothermal and biomass. These systems, which are deployed in small to large-scale capacities, are more cost-efficient and efficient in conserving energy.
