ORC Waste Heat to Power Market Outlook:
ORC Waste Heat to Power Market size was over USD 5.4 billion in 2025 and is estimated to reach USD 13.9 billion by the end of 2035, expanding at a CAGR of 11.1% during the forecast timeline, i.e., 2026-2035. In 2026, the industry size of ORC waste heat to power is evaluated at USD 6 billion.
The international ORC waste heat to power market is continuously witnessing increased exposure, and this momentum is highly driven by a rise in the need for energy efficiency for heavy industries, such as chemicals, petrochemicals, steel, and cement, stringent environmental regulations, and industrial decarbonization. According to official statistics published by the UNEP Organization in October 2024, nations are required collectively to reduce 42% of yearly greenhouse gas emissions by the end of 2030, along with 57% by 2035. This is projected to be initiated in the upcoming round of Nationally Determined Contributions (NDCs). Besides, the failure to enhance ambition in this objective is poised to result in a surge in temperature, ranging between 2.6 and 3.1 degrees Celsius, thus making it suitable for bolstering the market’s growth.
Furthermore, the presence of government incentives, emission reduction mandates, technological innovations, integration with renewable energy, and circular economy adjustment are other drivers fueling the organic rankine cycle (ORC) waste heat to power market internationally. As per official statistics published by the IEA Organization in June 2023, the government expenditure for clean energy denoted an investment of USD 1.3 trillion. Additionally, this played a centralized role in the rapid growth of clean energy investment, which further increased by almost 25% as of 2023. Besides, as per the September 2025 Energy Conversion and Management article, an estimated 99% of the global shipment for energy demand is readily met by fossil fuels, with marine gas oil and fuel oil accounting for almost 95% of the overall demand, thus boosting the market’s exposure.
