Waste Heat Recovery in Saudi Industry: The Overlooked Lever for Energy Efficiency in Saudi Arabia

Sector fit helps explain why the opportunity can be overlooked even when the need is visible. Grand View Research segments the Saudi market by petroleum refinery, chemical, cement, metal production & casting, paper & pulp, and power. Ken Research similarly describes end users including Oil & Gas, Manufacturing, Power Generation, Cement, Petrochemical, Metal Production & Casting, and Paper & Pulp. Ken Research says the Oil & Gas sector leads, and notes petroleum refineries account for the largest market share, citing high energy consumption and emissions mandates. It also highlights that key cities such as Riyadh, Jeddah, and Dammam dominate demand due to concentrated industrial activity across oil and gas, petrochemicals, and manufacturing.

Policy Pressure and Industrial Expansion Are Converging

Saudi policy and industrial build-out are providing practical reasons to revisit heat losses inside plants. Ken Research states that in 2023 the Saudi government implemented the National Industrial Development and Logistics Program (NIDLP) to enhance energy efficiency across sectors, including specific targets for waste heat recovery systems supported by financial incentives and regulatory support. Regional market dynamics reinforce that direction. In a Middle East & Africa market outlook, Grand View Research cites U.S. Energy Information Administration 2022 and notes that a significant portion of new refining capacity is expected to come from new projects in the region, pointing to the Jizan refinery in Saudi Arabia with a capacity of 400,000 b/d, reportedly online in 2021 and shipping products early in 2023. Such additions increase the relevance of on-site efficiency measures such as power and steam generation and preheating applications referenced in the regional outlook.

Technology choice is broad, and the “right” approach depends on the grade of heat and the operating profile. Ken Research lists system types including Organic Rankine Cycle (ORC), Steam Rankine Cycle (SRC), Thermoelectric Generators (TEG), and Heat Exchangers, and says ORC is gaining traction for converting low-temperature waste heat into usable energy. Custom Market Insights adds that globally, companies use ORC systems, TEGs, and heat exchangers to capture energy from sources such as exhaust gases. It also warns that a lack of education and outreach can inhibit adoption because industries may overlook or underestimate the value proposition. For Saudi Arabia, this underscores a simple execution point: measure and monitor heat flows so recovery projects compete fairly for capital.

Adjacent spending trends suggest the operational toolkit for capturing and managing waste heat is evolving in parallel. Mobility Foresights projects the Saudi Arabia heat recovery system market to grow from USD 14.6 billion in 2025 to USD 25.3 billion by 2031, at a CAGR of 9.7%, driven by rising energy prices, demand for efficiency, and efforts to decarbonize industrial processes. It also points to IoT-enabled monitoring tools for performance and predictive maintenance, and to modular and scalable units for diverse applications. In another indicator of momentum, a Futurism report cites the Saudi Energy Efficiency Center, stating energy management solutions reached USD 25.4 million in 2024, alongside growing adoption of intelligent thermal systems and equipment with waste heat recovery capabilities. Together, these signals strengthen the case for waste heat recovery Saudi Arabia decision-makers treat as a planned modernization step, not a retrofit afterthought.
