• 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

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

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
