                 Why wave energy?
Use of wave energy will contribute to:
• Higher diversification and security of energy supply
• Higher use of renewable energy resources
• Reduction of emissions like: CO2, NOx and SO2
• Lower environmental impact
• Conservation of important resources like oil and gas
• Can cover 50% of the world electricity consumption
                  - But research is needed and costly

                     Wave Dragon principle
The Wave Dragon is a slack-
moored wave energy converter
that can be deployed alone or in
parks wherever a sufficient
wave climate and a water depth
of more than 25 m is found.

                        The Wave Dragon is deployed
                        in a fjord with a wave climate
                        of scale 1:4.5 of the North Sea

       The EC Wave Dragon project objectives
   2004:      Reliable power production demonstrated
              and all wave situations tested
   2006:      Full size Atlantic unit 4 -7 MW unit to be
              demonstrated
   2009-10:   Power plant size to be demonstrated

                 Wave Dragon power plant



                             4 km
 Electricity for 40,000 to 60,000 homes can be
 generated from:
• 7 units in a 4 km line resulting in a power plant,
  size: 50 – 80 MW.
• A size of 3.2 km2, which is 75% of the space needed for
  offshore wind farms at the same power.
• At deep water (more than 25 meter) almost without visual
  impact.

         The EC Wave Dragon project: What next?
  • Demonstrate regular power production from
    December 2003
  • Demonstrate survivability – 12 months now
    with several storms
  • Optimise power production August 2004
  • Optimise structural design December 2004

         The EC Wave Dragon project: Conclusions

 Conclusions:
 The system works
 • Deployment March 2003
 • Power production to the consumer May 2003 as the first
   offshore wave energy converter in the world
 • Remote control system working October 2003
 The implementation
 • The planning for deployment in UK, Ireland, Spain,
   Portugal, France, Germany, Norway and/or Denmark by
   2006 of a 4 - 7 MW unit – producing electricity for 3,000
   to 6,000 homes - can begin
              The best economical conditions will be decisive for the site.
                            Even US has shown interest.
