Market Overview

The global ecosystem of technologies, systems, equipment, and services intended to capture and transform excess thermal energy otherwise lost as exhaust or by product from industrial processes, power plants, cement kilns, steel furnaces, and chemical plants into usable electricity, steam, or process heat is referred to as the waste heat recovery market. Organic Rankine Cycle (ORC) units, heat exchangers, economizers, and sophisticated heat pumps are examples of core solutions that improve energy efficiency, cut fuel use, and lessen greenhouse gas emissions while offering significant cost savings. Waste heat recovery innovations operate across high (>600°C), medium (150–600°C), and low (<150°C) temperature ranges, enabling applications such as power generation, feedstock and air pre-heating, moisture removal, cooling, and other industrial or utility processes that effectively utilize recovered thermal energy.

In June 2023, Ministry of Power (India) launched the Advanced Industrial Technology Demonstration Center (AITDC), also called Unnat Takniki Pradarshan Kendra (UTPRERAK), to promote energy-efficient technologies, including waste heat recovery through industry demonstrations and knowledge sharing. One of the main factors driving the global waste heat recovery industry is the rising cost of electricity. Investment in waste heat recovery technology is being encouraged by regulatory support and growing energy costs.

Waste Heat Recovery Market Trends

• Organic Rankine cycle (ORC) devices are increasingly being used to generate power efficiently from industrial heat.
• High-temperature (>600°C) waste heat recovery is receiving more attention for energy-intensive sectors like glass, steel, and cement.
• The expansion of low (<150°C) and medium (150–600°C) temperature recovery solutions for space conditioning, moisture removal, and feedstock preheating.
• The combined heat and power (CHP) systems and renewable energy with waste heat recovery.
