  • 8. RESOURCE Tides = rise and fall of sea levels Oceans and seas are acted upon by the • Gravitational forces of the sun and moon • Rotation of the earth Other influences such as wind and barometric pressure changes, resulting in storm surges, can also affect the sea water level Tides vary daily (ebb – flood), monthly (spring – neap) and can also have a seasonal variability All and any copyrights and other intellectual and industrial property rights, with regard to these files shall remain the sol e property of DEME Blue Energy. Nothing in these files, nor the ideas incorporated in these, can be used, disclosed or copied without the prior written consent of the proprietor. 8
  • 9. * In case of semidiurnal tide (most common) RESOURCE Daily stages of tides: Flood tide High tide Ebb tide Low tide Sea level rises over several hours, covering the intertidal zone The water rises to its highest level Sea level falls over several hours, revealing the intertidal zone The water stops falling 2x/ day * Water levels continuously change as a consequence of moving water masses. This implies water streams (currents, magnitude is bathymetry dependent) In this context two main harvesting principles are applied: Tidal barrage Tidal current Main advantage for capturing the resource is its predictability All and any copyrights and other intellectual and industrial property rights, with regard to these files shall remain the sol e property of DEME Blue Energy.

  • 11. TIDAL BARRAGE A basin fills and empties according the tidal stages. This basin can be a lagoon (natural or constructed) or river mouth (estuary). Two ways of using the tidal barrage turbines: Ebb Generation • • Flood tide First hours of ebb tide • Remaining ebb hours filling of basin sluices are closed in order to build up hydrostatic head sluices open (electricity generation) e.g. La Rance, France Two-way Generation Electricity generation in both ebb en flood tide direction All and any copyrights and other intellectual and industrial property rights, with regard to these files shall remain the sol e property of DEME Blue Energy.

  • 20. CHALLENGES  Need for advanced stage technologies of Tidal Energy Converters (TECs): development of technology towards mature and industrial products  Installation of TEC components in harsh site conditions (current velocity, wave/wind interaction)  Operation and maintenance friendly devices  Survival in storm conditions (wave interaction)  Electrical grid: interconnection, grid integration & balancing  adequate and stable regulations & permissions concerning: site assesment, environmental aspects & maritime spatial planning  Economics: funding (support with Blue Certificates?), financing & insurance All and any copyrights and other intellectual and industrial property rights, with regard to these files shall remain the sol e property of DEME Blue Energy.

  • 27. SUMMARY • Tidal energy has the potential to become the next generation of offshore renewable energy: it can help to meet the climate change targets and will bring social & economic benefits • OEMs (Original Equipment Manufacturers) are getting organized for further development and supply • Incentives by governments and Europe are there to launch the first tidal arrays (e.g. 7th Framework Programme, Horizon 2020, Feed-in tariffs, etc.) • First tidal projects are in the pipeline in Europe • If challenges can be met and first projects prove to be economical viable, this new industry is ready for commercialization All and any copyrights and other intellectual and industrial property rights, with regard to these files shall remain the sol e property of DEME Blue Energy.
