The global energy landscape is undergoing a significant transformation as governments and industries seek sustainable alternatives to fossil fuels. Among emerging renewable energy sources, tidal power is gaining increasing attention due to its predictability, low carbon footprint, and long-term energy potential. Tidal power harnesses the kinetic and potential energy generated by ocean tides to produce electricity, offering a reliable and renewable source of power compared to intermittent sources such as wind and solar.

The global tidal power market size was USD 123.6 million in 2023, which is estimated to be valued at USD 144.6 million in 2024 and is projected to reach USD 501.4 million by 2031, growing at a CAGR of 19.44% from 2024 to 2031. This strong growth trajectory reflects rising investments in marine renewable energy, supportive government policies, and continuous technological advancements in tidal energy systems.

As the world accelerates its transition toward carbon neutrality, tidal power is emerging as a promising component of the global renewable energy mix, particularly for coastal and island nations.

Executive Summary

The tidal power market is witnessing rapid expansion due to increasing demand for clean energy, rising concerns over climate change, and growing investments in marine energy infrastructure. Tidal energy offers unique advantages such as high energy density, predictability of tides, and minimal visual impact compared to other renewable technologies.

Although the market is still in its early commercialization phase, pilot projects and large-scale deployments across Europe, North America, and Asia-Pacific are laying the foundation for long-term growth. With continuous R&D efforts aimed at reducing installation costs and improving turbine efficiency, tidal power is expected to play a crucial role in achieving global renewable energy targets.
