Facts & Figures

Marine energy (sometimes called ocean energy) refers to the renewable energy that can be generated from the energy contained in the world's oceans, seas and rivers. Specifically, marine energy can be captured from waves, tides, difference in salinity gradients, and the heat stored in surface ocean water. This energy can be converted into reliable, sustainable and cost-competitive electricity that has several advantages over fossil fuels, and complements other forms of renewable energy like solar and wind:

  • Marine energy is renewable: The energy stored in oceans, seas and rivers is inexhaustible

  • The power output is highly predictable and is always available (compared to wind and solar energy): This makes marine energy a reliable source of energy

  • Technologies are environmentally friendly: They produce no by-products, waste, and greenhouse gases during operation

  • Devices can be integrated in multiple-business cases in collaboration with the offshore, maritime and deltatech sectors

  • Marine energy technologies have no visual impact on the land and shoreline

Global potential by 2050

Marine energy could:

  • Generate 300 GW of renewable energy. This is enough to supply electricity to 350 million households worldwide. Realising this potential is necessary to achieve the ambitious goals set out in the Paris Agreement on climate change

  • Build an annual market generating >€100 billion of economic value in the entire supply chain from manufacturing and deployment to operation and maintenance

  • Create >650.000 new jobs

European potential by 2050

Marine energy could:

  • Generate 100 GW of renewable energy and produce up to 10% of Europe’s electricity consumption. That’s as much as the daily electricity needs of all the households in France, Ireland, Portugal, Spain and the United Kingdom together

  • Tap into a global market worth >€100 billion. 50% of all marine energy companies are based in the European Union. Therefore, Europe is well-positioned to become the global industry leader in the marine energy sector

  • Create >200.000 new jobs
