Presentation Transcript

  1. Marine Energy, Scotland and the EU Professor Ian Bryden Chair of Renewable Energy The University of Edinburgh

  2. 1974: Initial experiments on the Duck The European Capability • Serious interest in marine renewable energy starting in Europe in the 1970s, especially: • Edinburgh (Salter) • Lisbon (Falcao) • Trondheim (Falnes) • …. Industry and commerce are now development a marine renewable industry but vital new understanding is still being developed in the Universities

  3. Academic Capabilities

  4. The “accepted” model of development

  5. MARINE MARINE The “Learning Curve” R D D D £/MW ScottishEnterprise MW to market

  6. Pace of Development • Full scale prototype devices are installed and tested • Marine Energy is moving towards commercial viability

  7. The Wave Resource • The North Atlantic acts as an immense collector of wind energy • Resource is massive and largely forecastable

  8. The Tidal Resource • The form of the North Atlantic Coast and the North Sea and other European basins result in complex tidal distributions • The tidal resource is extreme, localised and predicable Pentland Firth

  9. Technology Development • Requires detailed understanding at the design stages • Requires detailed assessment at the prototype stages • Testing at EMEC and other test sites such as those in Portugal and Ireland, • Closure of the design/development/deployment loop

  10. The EMEC Wave Test Site • 2km from shore • 50m water depth • Four berths • Atlantic waves regime • 25kW/m + energy level • 20m+ peak wave

  11. The EMEC Tidal Test Site • 5 Berths 10-50m • Grid connected • 3.5m/s flow • Sheltered area • Available since 2007

  12. Marine Energy Resource • Theoretical resource: Energy contained in the entire marine resource. • Technical resource: The proportion of the theoretical resource that could be exploited • Practical resource: The proportion of the technical resource that can be exploited after consideration of external constraints The values of each of these is gradually being assessed

  13. How Much Energy? • Wave* • Technical resource in Europe likely to exceed 50GW installed capacity (this is still a matter of informed conjecture) • Tidal Current • Technical European resource likely to exceed 25GW installed capacity (this is a matter of often misguided conjecture) Even cautious estimates such as these suggest major opportunities for development *Extrapolated from the Carbon Trust Report “Future Marine Energy (Results of the Marine Energy Challenge: Cost competitiveness and growth of wave and tidal stream energy)”

  14. Conclusions • The European and Scottish wave and tidal current resource is massive and represents an appreciable proportion of demand • There are no “showstoppers” in terms of environmental and technical constraints • Scottish research, development and implementation capability is at the forefront of the new European industry

  15. A suggestion! • A Forum for open communication on generic difficulties facing developers in the marine renewable sector. • Should include the very best expertise from the broader marine sector, such as: • Testing organisations • Academia • Trade associations • It should be outward looking but primarily directed to the building of a marine renewable industry

  16. The Marine Renewable Forum • Should not be: • Yet another lobbying organisation • Linked to any other organisation • A consultancy organisation • Should be: • Able to facilitate and broker the exchange of generic knowledge between developers, researchers, test centres, public and private bodies • A net benefit to the sector and not “yet another layer of bureaucracy”
