The low-temperature waste heat to power generation market is emerging as a significant segment within the renewable energy and industrial efficiency sectors. This market focuses on technologies that convert low-grade waste heat—often between 70°C and 200°C—into usable electricity, enhancing energy efficiency and reducing greenhouse gas emissions. With the push towards sustainable practices and energy conservation, the sector is witnessing rapid technological advancements and increased adoption across various industries.

Market Overview

Low-temperature WHP generation primarily leverages heat that would otherwise be wasted during industrial processes. This is achieved using technologies such as:

Organic Rankine Cycle (ORC): A widely adopted method that uses organic fluids with low boiling points to generate power from low-grade heat.

Kalina Cycle: Employs a water-ammonia mixture, offering higher efficiency in some applications.

Thermoelectric Generators (TEGs): Use the Seebeck effect to directly convert heat into electricity without moving parts.

These systems can be implemented in industries such as manufacturing, chemical processing, oil and gas, cement, glass production, and even data centers.

Market Drivers

Growing Energy Efficiency Goals: Governments and organizations are increasingly prioritizing energy conservation, pushing industries to adopt waste heat recovery systems.

Rising Energy Costs: As energy prices surge globally, WHP technologies offer a cost-effective solution to harness unused energy.

Environmental Regulations: Stricter environmental policies are driving industries to reduce carbon emissions, making waste heat recovery an attractive option.
