Tidal energy market seen reaching $8.6 billion by 2033

Allied Market Research projects the global tidal energy market will grow from $1.2 billion in 2023 to $8.6 billion by 2033 as governments and investors back marine renewables. The forecast points to rising demand for predictable clean power, but high upfront costs, grid limits and environmental reviews still slow deployment. Why it matters: - Tidal energy could become a more reliable piece of the clean power mix because tidal cycles are highly predictable and easier to forecast than solar or wind. - The market forecast signals growing commercial interest in marine renewables as governments and utilities look to cut fossil-fuel use and improve energy security. - The report projects the tidal energy market will reach $8.6 billion by 2033, up from $1.2 billion in 2023. What happened: - Allied Market Research published a report on June 19, 2026, projecting the tidal energy market to grow at a 21.9% compound annual growth rate from 2024 to 2033. - The report says governments, utilities and private investors are increasing support for tidal and broader marine energy projects. - The market covers tidal barrages, tidal stream generators, tidal fences, underwater turbines and hybrid marine energy platforms. - Download PDF brochure The details: - Tidal energy systems capture kinetic and potential energy from rising and falling tides, ocean currents and marine water flows. - The report says tidal systems are deployed in coastal regions with strong tidal currents and large tidal ranges. - Tidal power produces electricity without direct greenhouse gas emissions during operation. - Advances in underwater turbines, marine engineering, energy conversion systems and grid integration are improving commercial viability. - The report cites growing support for pilot projects, commercial-scale installations and research programs across Europe, North America, Asia-Pacific and the Middle East. - The report says the broader marine energy market includes tidal, wave, ocean thermal and salinity gradient technologies. - The report lists major market participants including the European Marine Energy Centre, Andritz AG, Orbital Marine Power Ltd., Sustainable Marine Energy Ltd., Nova Innovation Ltd., SIMEC Atlantis Energy Ltd., HydroQuest SAS, Verdant Power Inc., Hammerfest Strom AS and Minesto AB. Between the lines: - Tidal energy has a practical edge because power output can be forecast years in advance, which helps grid operators plan capacity and stability. - The technology still faces real barriers: high capital spending, saltwater corrosion, maintenance complexity, grid connection gaps and lengthy environmental permitting. - The report suggests the strongest near-term opportunities may be in projects that pair tidal power with desalination or use digital tools such as predictive maintenance and smart grid integration. - Europe remains the largest regional market, supported by strong policy backing, advanced engineering and climate targets. What’s next: - The report expects continued investment in research, demonstration projects and commercial installations over the next decade. - Countries with extensive coastlines, including the U.S. and India, are expected to keep evaluating tidal power as part of broader renewable energy plans. - The report says lower costs, better turbine efficiency and improved operating reliability could expand deployment if technology and permitting hurdles ease. - Buy the full report
