The Global Marine Energy Market was valued at USD 2.11 billion in 2025 and is estimated to grow at a CAGR of 9.7% to reach USD 4.94 billion by 2035.
Market growth is supported by rising public-sector funding mechanisms that encourage research, pilot deployment, and early commercialization of ocean-based renewable power systems. Marine energy represents electricity generated from ocean resources such as tidal movements, wave motion, water currents, and thermal differences, offering a sustainable alternative to conventional energy sources. These systems convert the kinetic and thermal potential of seawater into usable power with minimal emissions. Marine energy is increasingly valued for its predictability, long operating life, and contribution to decarbonization goals. Growing interest in renewable solutions with lower environmental impact continues to strengthen demand. The market also benefits from the need for energy sources that provide stable output and resilience against climate variability. Integration of marine energy projects with existing offshore renewable infrastructure improves cost efficiency and grid connectivity. Hybrid renewable configurations further enhance utilization rates and support uninterrupted electricity generation, reinforcing the long-term role of marine energy within diversified clean power portfolios.
The salinity gradient power segment is projected to reach USD 500 million by 2035. Increased investment in advanced membrane development improves energy conversion efficiency while reducing system costs, which enhances commercial readiness and supports wider deployment in regions with suitable water resources.
The marine energy-powered desalination applications segment will grow at a CAGR of 10.7% through 2035. Rising freshwater demand in coastal and island regions accelerates interest in clean power solutions that reduce operating costs, improve energy efficiency, and support long-term water security.
U.S. Marine Energy Market held 89.9% share in 2025 and is expected to generate USD 200 million by 2035. Strong renewable energy targets, growing institutional interest, and increasing private investment continue to reinforce regional leadership and long-term market potential.
