ORC Waste Heat to Power Market Size - By Power Output, Growth Forecast, 2026 - 2035

ORC Waste Heat to Power Market Size

According to a recent study by Global Market Insights Inc., the ORC waste heat to power market was estimated at USD 4.6 billion in 2025. The market is expected to grow from USD 5.2 billion in 2026 to USD 12.9 billion by 2035, at a CAGR of 10.6%.
 

• Industrial decarbonization and stringent environmental regulations stand as foundational growth drivers for the ORC (Organic Rankine Cycle) waste heat to power market. Industries such as cement, steel, petrochemicals, and chemicals generate vast quantities of low-grade heat—typically between 80°C and 350°C—that would otherwise go unused. ORC technology enables the conversion of this waste heat into electricity, reducing greenhouse gas emissions and improving overall plant efficiency.
   
• For instance, Europe’s Clean Industrial Deal and the U.S. Inflation Reduction Act include provisions incentivizing waste heat recovery solutions, prompting industrial operators to implement ORC systems to comply and reduce carbon footprints. In many regions, adoption is fueled by binding emission-reduction targets and energy-efficiency mandates.
   
• Rising energy prices and cost-reduction pressures are accelerating ORC adoption across energy-intensive sectors. As energy prices surge globally, industrial firms face mounting operational expenses. ORC systems offer compelling economic benefits: they generate electricity from heat that would otherwise be wasted, effectively lowering energy bills and enhancing profitability. Moreover, decreasing levelized cost of electricity (LCOE) for ORC systems thanks to greater economies of scale and technological improvements has made them accessible for midsized facilities that were previously financially marginal.
   
• Technological advancements in ORC systems are significantly boosting their performance and affordability. Improvements in working fluids—from low-boiling organic compounds to emerging supercritical CO2 options—alongside innovations in high-efficiency heat exchangers and scroll or screw expanders, have raised thermal efficiency while reducing maintenance requirements. Furthermore, digital monitoring, automation, and predictive maintenance tools enhance system reliability, uptime, and lifecycle economics. These engineering leaps are expanding ORC’s viability across a wider array of heat sources and operational conditions.
   
• Supportive government policies and financial incentives are instrumental in steering ORC market growth. Jurisdictions across North America, Europe, and Asia offer tax credits, subsidies, and renewable energy mandates that explicitly include waste heat recovery installations. Incentives like the U.S. Production Tax Credit, Canada’s Clean Technology Investment Tax Credit, and Europe’s Green Deal enable accelerated returns on ORC investments. Additionally, industrial decarbonization funding—such as the U.S. Department of Energy’s USD 104 million FOA—lowers the financial risk for early adopters and stimulates deployment.
   
• Expanding applications across geothermal, biomass, and off-grid or remote power systems are diversifying ORC use cases. ORC technology has proven especially suitable for low-to-medium thermal sources such as geothermal reservoirs, biomass combustion flue gas, and internal combustion engine exhaust. It’s also gaining traction in hybrid renewable systems—combining solar, geothermal, and ORC—to ensure stable energy output.
   
• In October 2025, Clean Energy Technologies (CETY) partnered with RPG Energy Group to deploy a Clean Cycle ORC system at a Fortune 100 industrial manufacturing plant in Martin, Tennessee. This U.S. installation marked one of the first large-scale industrial ORC deployments, capturing waste heat that would otherwise be lost and converting it into clean electricity.
   
• Modularization and scalability of ORC platforms support broader market penetration. Manufacturers are increasingly offering compact, factory-built ORC units that are easy to install, even in challenging site conditions. These modular systems allow customers to scale capacity incrementally—starting with small (<1 MW) installations and expanding to multi-MW setups—while keeping installation timelines and capital costs low. Such flexibility appeals to distributed energy systems, remote industrial sites, and off-grid applications, enabling wider adoption even among smaller operators.
   

ORC Waste Heat to Power Market Trends

• Rapid growth in energy-intensive industries such as cement, steel, and chemicals generates significant low-grade waste heat. ORC systems efficiently convert this heat into electricity, improving energy efficiency and reducing operational costs. As global manufacturing scales up, particularly in emerging economies, the availability of waste heat sources increases, creating strong demand for ORC technology. This trend aligns with industrial sustainability goals and supports cost-effective power generation without additional fuel consumption.
   
• Governments worldwide are enforcing strict emission regulations to curb greenhouse gas emissions. ORC systems help industries comply by reducing carbon footprints through waste heat recovery. Policies like the EU Green Deal and U.S. Inflation Reduction Act incentivize clean technologies, making ORC adoption a strategic choice for compliance and sustainability.

It exemplifies the rising industrial demand for low-grade waste heat recovery and demonstrates the financial benefits of on-site power generation. 
   
• Global energy prices remain volatile, pushing industries to seek cost-saving measures. ORC technology offers a practical solution by converting unused heat into electricity, lowering energy bills and improving profitability. This economic advantage is particularly attractive for sectors with high thermal losses, such as petrochemicals and glass manufacturing. As energy efficiency becomes a competitive differentiator, ORC systems will gain traction as a reliable and cost-effective technology.
   
• For citation, in October 22, 2025, Turboden, a Mitsubishi Heavy Industries Group company, commissioned a 19 MW ORC plant at Strathcona Resources’ Orion SAGD facility in Cold Lake, Alberta. This system recovers low-grade heat (≈150 °C) from steam-assisted gravity drainage processes, generating electricity that offsets roughly 80% of the facility’s grid usage. This project directly addresses emission reduction mandates and high energy costs in oil sands extraction.
   
• Continuous innovation in working fluids, heat exchangers, and turbine designs has enhanced ORC efficiency and reduced maintenance costs. Emerging supercritical CO₂ cycles and advanced organic fluids enable better performance at lower temperatures, expanding ORC applications. Additionally, digital monitoring and predictive maintenance tools improve reliability and lifecycle economics. These advancements make ORC systems more adaptable and appealing for diverse industrial environments.
   
• ORC technology is increasingly integrated with renewable energy sources like geothermal and biomass, creating hybrid systems that ensure stable power generation. This synergy supports grid reliability and sustainability goals, especially in regions with growing renewable penetration. ORC’s ability to utilize low-temperature heat makes it ideal for complementing intermittent renewables, positioning it as a critical component in future energy systems.
   
• For illustration, the U.S. federal government expanded tax incentives under the Inflation Reduction Act, classifying Waste Energy Recovery Property—including ORC systems—as eligible for a 30% investment tax credit (ITC) through December 2024. These incentives aim to accelerate decarbonization in energy-intensive industries by offsetting upfront project costs. By making ORC installations more financially attractive, the policy strengthens demand for clean energy technologies.
