Objective

Objectives:
The primary objectives are to contribute to the EU goals of:· Reaching a 12% share of renewable energy sources of total energy consumption and a 22% share of gross electricity consumption from renewable energy sources by 2010.· Reducing the greenhouse gas emission by 8% by 2010 based on the 1990 level.· Contributing to improving European self-sufficiency and diversification of energy supply. The objectives are reached through long-term field-testing on a grid connected overtopping wave energy converter with all systems installed. The power of the scale prototype corresponds to a 4-10 MW full-scale prototype. The Wave Dragon is a slack moored wave energy converter that can be deployed in large parks wherever a sufficient wave climate and a water depth of more than 20 m are found - typically this is the case in the North Sea and in the Atlantic. Description of the work: The basic test rig construction (267 tonnes) is provided through a project sponsored by the Danish Energy Authority. After designing and installing 6 additional turbines required for the RTD activities, a number of scientific issues that cannot be fully explored through laboratory testing are investigated: · Long-term field testing of turbine operation· Control strategy testing and optimisation· Power monitoring and evaluation· Stress and strain measurements & analysis· Mooring and cable systems analysis. Measured results will be compared to previous laboratory test results by calibrating and validating the model tools developed in the previous EU CRAFT project (JOR3-CT98-7027). The test site is in protected waters in Nissum Bredning, Denmark, where the wave climate resembles North Sea conditions (scale 1:4.5). The most promising European markets and their characteristics are assessed, and regional market characteristics assessed. Environmental impact assessment and life cycle analysis are performed. Dissemination includes the international audience, national and international networks within wave power, and key players in the long-term implementation strategy. Power production is graphically presented at the project web site, where also video clips are available. Expected Results and Exploitation Plans: A power production price of 0.11 €/kWh will be documented at project finalisation with a long-term production price of 0.04 €/kWh foreseen. A full-scale prototype demonstration in exposed waters is expected from 2006, marking the start-up of large-scale commercial exploitation of offshore wave power. The deployment of Wave Dragon will - through the already formed development company -contribute to the establishment of a completely new industry like the wind industry offering new opportunities for the declining European oil and gas offshore industry. The long-term employment in Europe is foreseen to 6,000, with an installed power of 2,400 MW expected by 2016.
