02

Restraint: High capital expenditures and complex marine infrastructure increasing project barriers

One of the most significant restraints on tidal energy systems is the very high upfront project costs combined with challenging marine infrastructure requirements. Tidal plants typically demand substantial capital investment for engineering, subsea construction, grid connection, and specialized vessels, with reported costs of USD 3,000–8,000 per kilowatt installed, much higher than wind or solar technologies. These costs lengthen payback periods and reduce attractiveness to investors who may prefer faster‑return technologies, directly slowing revenue growth and limiting new project development in cost‑sensitive regions. Additionally, suitable coastal or estuarine sites often need bespoke civil works and grid upgrades, further elevating pre‑development expenditures and permitting delays. This economic barrier constrains market demand and revenue potential, particularly where financing remains constrained and competitive alternatives like offshore wind are more cost‑competitive.

Use Cases of Tidal Energy Systems in Power Generation & Desalination

Power Generation : Tidal energy systems are most widely used for large‑scale power generation, where the key technologies include tidal stream generators and tidal barrage systems that convert the kinetic and potential energy of tides into electricity. Tidal stream turbines are underwater devices that resemble wind turbines and capture energy from fast‑moving tidal currents, offering predictable and steady power that can feed into coastal grids with high reliability compared to wind or solar. Tidal barrages use the height difference between high and low tides to drive turbines in dam‑like structures across estuaries, historically proven at sites such as La Rance in France. The unique advantage of tidal power lies in its predictability and high energy density owing to water’s density, making it a valued renewable source for consistent baseload generation.
Desalination : In desalination applications, tidal energy systems supply clean and renewable power to coastal freshwater production facilities by leveraging electricity generated from tidal turbines. Tidal electricity, mainly from tidal stream generators or barrage‑linked turbines, can power energy‑intensive processes such as reverse osmosis or electrodialysis to remove salt and impurities from ocean water, reducing reliance on fossil fuels and lowering operational emissions in water‑scarce regions. The consistent and predictable nature of tidal generation supports continuous operation of desalination plants, particularly beneficial for island nations and arid coastal communities. Integrating tidal generation with desalination helps deliver sustainable water solutions while minimizing greenhouse gas emissions and energy costs.
Marine Propulsion : The marine propulsion application of tidal energy is an emerging area where tidal systems indirectly support vessel operations by providing renewable electricity for charging electric propulsion systems and on‑board energy needs. Instead of directly driving ship propellers from captured tidal flows, tidal turbines and hydrokinetic devices supply power to ports and charging infrastructure that electric and hybrid vessels can utilize, enabling reduced fuel consumption and lower emissions for ferries, research vessels, or autonomous marine systems. Research prototypes like tethered undersea kites highlight future potential of embedding energy capture closer to marine platforms, though widespread commercial use for direct propulsion remains under development. The predictable cyclic energy from tides ensures a stable renewable power source to support marine electrification strategies and enhance sustainability in maritime transport.
