The global shift toward low-carbon electricity is one of the strongest drivers of ocean power development. Utilities and governments are diversifying renewable portfolios beyond solar and wind, creating opportunities for marine-energy technologies. Ocean power can also complement variable renewable generation by providing a different production profile, particularly where tidal resources are strong and predictable.
Growth Driver 2: Technological Advancements
Advancements in underwater turbines, wave-energy converters, lightweight and corrosion-resistant materials, mooring systems, subsea transmission, sensors, and digital monitoring are improving the technical performance of ocean-energy projects. Artificial intelligence and remote-monitoring technologies can further support predictive maintenance and reduce the need for frequent offshore intervention.
Growth Driver 3: Rising Demand for Reliable Coastal and Offshore Energy
Growing electricity demand from coastal infrastructure, ports, islands, offshore industries, desalination plants, and data and telecommunications infrastructure is creating new application opportunities. Ocean power can provide locally generated renewable electricity in locations where land availability is constrained or where importing conventional fuels is costly.
Restraint –
High Development and Deployment Costs
The marine environment presents considerable engineering challenges. Ocean-energy equipment must withstand waves, currents, saltwater corrosion, biofouling, storms, underwater pressure, and mechanical stress. Installation and maintenance can require specialized vessels and offshore equipment, increasing project costs. Regulatory approvals, environmental assessments, grid connection requirements, and limited deployment experience can also lengthen project-development timelines.
