Waste Heat to Power (WHP) Market size is valued at USD 21.57 Billion and is forecast to grow at a CAGR of 12.8% from 2023 to 2029, reaching nearly USD 49.85 Billion.

1. Market Size

In 2023, the Waste Heat to Power market stood at USD 24.5 billion. By 2030, it is anticipated to reach a staggering USD 65.6 billion, reflecting a CAGR of approximately 15% over the forecast period. This significant growth is propelled by the rise in global industrialization, increasing energy costs, and environmental mandates demanding clean and efficient energy solutions.

2. Overview

Waste Heat to Power systems capture and convert surplus heat energy from industrial processes into electricity. This waste heat is commonly released through exhausts, furnaces, kilns, and engines. By transforming it into usable power, WHP not only improves the energy efficiency of facilities but also contributes to global decarbonization goals.

WHP technologies are playing a pivotal role across sectors including oil & gas, cement, metals, chemicals, and glass manufacturing. Moreover, WHP systems are increasingly integrated into renewable power solutions and smart grids to enhance overall sustainability.

3. Market Definition

The Waste Heat to Power market encompasses technologies and systems designed to recover thermal energy and convert it into electricity. These systems are typically based on three major technologies:

  • Steam Rankine Cycle (SRC): Widely used in high-temperature industrial applications.
  • Organic Rankine Cycle (ORC): Ideal for low to medium temperature heat recovery.
  • Kalina Cycle: Utilizes a mixture of water and ammonia for higher thermal efficiency at varying temperatures.

WHP solutions range from small-scale units (<1 MWe) to large installations (>10 MWe), serving diverse industrial applications based on the nature and quantity of waste heat available.

4. Market Growth Drivers & Opportunities

a. Industrial Energy Efficiency
The need for cost-effective, sustainable energy solutions is compelling industries to deploy WHP systems. Recovering and reusing thermal energy significantly reduces operational costs and enhances energy productivity.
