The market is expected to grow from USD 5.10 billion in 2025 to USD 8.47 billion by 2035 at a CAGR of 5.2%. This growth is driven by rising investments in pipeline and marine infrastructure and stricter corrosion control regulations. The USA Pipeline Safety Administration’s updated integrity rule, enforced in 2024, has boosted demand for protection systems. NACE International’s revised standards have further reinforced adoption. Industry seminars on corrosion prevention have promoted these technologies as vital for asset longevity.
Digital twin modeling has become important for predictive corrosion analysis. Schweitzer Engineering Laboratories announced IoT-enabled sensors in 2024 to enable real-time alerts. T.D. Williamson received the 2024 Corrosion Innovation Award for its low-power impressed-current system. Sacrificial anode installations are expected to hold about 55% of the industry by 2035. Marine applications are projected to contribute nearly 35% of demand. Pipeline assets account for 50% of global installations, reflecting infrastructure reliance. As sustainability mandates intensify, these protection systems will remain essential for extending asset life.
Looking ahead, the next decade will be defined by the convergence of cathodic protection with smart infrastructure frameworks and lifecycle-cost optimization models. Governments and private operators are increasingly embedding corrosion control into broader asset management platforms, integrating cathodic protection data with SCADA systems and digital twins for holistic infrastructure intelligence. This shift will drive demand for modular, retrofittable solutions that reduce downtime and support predictive maintenance.
As ESG compliance becomes non-negotiable for industrial asset operators, cathodic protection will transition from a technical requirement to a strategic lever-critical not only for operational continuity but also for sustainability disclosures and regulatory alignment. Markets with aging infrastructure and aggressive climate environments are expected to see accelerated adoption of hybrid systems that combine sacrificial and impressed current elements for extended lifecycle performance.
