Transcript and Presenter's Notes

Title:


1
  • Energy from the Sea BioFuels, Currents, Tides
    Wind
  • Panel Contribution by Dr Tony Raven
  • Director, Research Innovation Services
  • University of Southampton
  • UK

2
Solent Region
  • Southampton and Portsmouth Port Cities on south
    coast of the UK
  • 4th largest UK commercial port 41M tonnes p.a.
  • Home to 67 of the Royal Navy surface fleet.
  • Centre of the European cruise industry
  • 67 of the port power comes from geothermal and
    CHP systems

3
University of Southampton
  • UK Top 10 and Global Top 100 research university
  • Major strength Maritime Studies
  • 150 academic staff across 19 Schools from
    Maritime Law Archaeology to Ship Science
  • Leading UK University in Sustainability
  • 188 academic staff and 266 PhD students
  • National Oceanography Centre

4
Ocean Energy
  • Offshore Wind
  • Wave
  • Tidal
  • Algal Biofuels
  • Deep water oil
  • Gas Hydrates

5
Offshore wind
  • 1.1GW current global capacity virtually all in
    Europe
  • After an early start by Denmark, UK is set to
    become far and away the dominant player.
  • By 2020 UK is expected to have 29GW out of 66GW
    globally (45) with gt90 in the EU

6
Offshore wind
  • Major UK program for offshore wind to meet legal
    obligation
  • 0.6GW installed
  • 8GW permitted
  • 25GW about to be announced for 2020 operation
  • 15 renewables obligation by 2020

7
Offshore wind
  • Significant issues
  • Foundations/Installation
  • Reliability
  • Repair and Maintenance Logistics
  • Investment (2.5x cost onshore)
  • Skills
  • Dock space

Installation vessels absolutely are the supply
chain limit, before turbines - Vestas
8
Tides and Tidal Stream
  • UK has 80 of Europes tidal stream energy
  • Of 20 significant potential sites worldwide, 8
    in the UK
  • 30 more expensive currently than offshore wind.
  • Major sources are remote from the population
    centres (subsea power cable)
  • Predictable power

9
Tides and Tidal Stream
  • Severn Barrage
  • Estimated 5 of UK supply
  • Postponed (cancelled?)
  • 40Bn cost
  • Small scale commercial operations
  • Strangford Lough (1.2MW)
  • Anglesey (10.5MW) -2011
  • Pentland Firth (1.3GW) - 2020

10
Wave Power
  • Pelamis Project
  • Articulated structure
  • 180m x 4m? for 750kW
  • Worlds first commercial wave energy facility
  • Installed offshore Portugal and Scotland
  • Anaconda
  • Rubber tube filled with water
  • 150m, 7m? for 250kW in 2m waves
  • 1MW 100 tonnes

11
Wave Power
  • Issues
  • Separation of wave power from centres of
    population
  • Grid bottlenecks
  • Reliability of mechanisms and lubrication in a
    harsh environment
  • Skills
  • Finance
