Wave Dragon has started the development of a 1.5 MW North Sea Demonstrator.

The development of a 1.5 MW Wave Dragon demonstrator provides a possibility for deployment of the WD technology in more benign wave climates than suitable for the 4 MW and 7 MW Wave Dragon devices.

The design work is based on experiences from >20.000 test hours with a smaller prototype. The plan is to deploy the 1.5 MW demonstrator offshore Hanstholm at the test center DanWEC, Denmark.

Aalborg University will be responsible for basin tests of a 1:50 model, performing the necessary tests to establish the forces in the mooring cables for varying floating positions of the platform.

ESB International will establish the necessary design base for the grid connection.

The project is supported by the Danish Energy Authority’s EUDP program.

Background Information

Wave Dragon’s Renewable Energy Technology

Wave Dragon is a large-scale technology for the generation of electricity from ocean wave energy. Invented by Erik Friis-Madsen, it has been developed with funding support from the European Union, the Welsh Development Agency, the Danish Energy Authority and the Danish Utilities PSO Programme.

A 1:4.5 scale prototype launched in 2003 was the world’s first offshore grid-connected wave energy conversion device. Deployed off the coast of Denmark at Nissum Bredning, this test unit has accumulated over 20,000 hours of experience supplying electricity to domestic homes.  Wave Dragon has achieved a breakthrough in wave energy conversion efficiencies. Excellent sites for wave energy power stations exist around the world, typically located 5-25km offshore, including the whole of Europe’s Atlantic coastline.

Generating electricity from ocean wave energy avoids the release of carbon dioxide associated with power stations which burn natural gas, oil or coal.  Wave Dragon’s technology allows energy generation on the same scale as traditional power plants. Extensive commercial deployment should contribute materially to the reduction of carbon emissions and their known effect on global climate change.

Wave Dragon’s Full-Scale Demonstrator in Wales

Wave Dragon is ready to construct and deploy a full-scale commercial demonstration unit in Pembrokeshire.  With a capacity of 7 MW, this unit will be built at Pembroke Dock and will be located two to three miles off St Ann’s Head and tested for three to five years only, in order to gain operational experience and knowledge of energy transfer efficiencies. Even this single demonstrator unit should produce enough clean and green electricity each year to meet the annual demand of between 2000 and 3000 homes, subject to grid connection capacity. This clean generation will offset the release of about 10 000 tonnes of carbon dioxide every year, the main greenhouse gas contributing to global warming and climate change. In a high energy wave climate, as found off the west coasts of Scotland and Ireland, one Wave Dragon unit will produce 50 GWh per year, offsetting 39 000 tonnes of carbon dioxide when comparing with coal-based power production.

The temporary demonstration site has been selected to be close to manufacturing facilities in South Wales and to connections to the local electricity grid. It is out of the way of major shipping lanes and other hazards. This initial Wave Dragon location is close to shore to allow frequent testing and promotional visits. Once the demonstration is completed successfully, future commercial wave farms will be further offshore to make use of more powerful sea conditions.  They will be invisible from the coast.

Wave Dragon Submits Environmental Impact Assessment Statement and Offshore Consents

April 27 2007, revised August 2009

Friday April 27 2007 the Wave Energy developer Wave Dragon Ltd has taken the first major step to deploy the Worlds Largest Wave Energy Converter (WEC) by submitting their Environmental Impact Statement. This follows almost two years of Environmental Impact Assessment consultations, studies and surveys. The Wave Dragon Project is part funded by European Objective 1 funds through the Welsh Assembly Government.

Hans Christian Sørensen (Chairman of the Wave Dragon Board) stated today; “This is an important milestone in the commercialisation of Wave Energy in general and the Wave Dragon technology in particular. Wave Dragon is, through this application, taking the first step in establishing a 70MW wave power plant in the Celtic Sea after 2012.”

The project is the result of 20 years of research and development and will deploy a 7MW WEC off the Dale and Marloes Peninsula (Pembrokeshire) during 2011/2012.

What happens now:

Wave Dragon has submitted three offshore consents to the DTI and DEFRA. Any concerns arising will then be forwarded and discussed with Wave Dragon before a formal decision is made. We will also be working with The Crown Estates and Pembrokeshire Coastal National Parks Authority towards a Lease and Planning Permission respectively.

Time Table:

End 2010 - Wave Dragon hopes to have successfully acquired our consents

Background Information:

Wave Dragon first Pembrokeshire Unit:

The unit off Pembrokeshire will be a 7 MW device and located two to three miles northwest of St Ann’s Head and tested for three to five years only, in order to gain operational experience and knowledge on the energy transfer efficiencies. Commissioned in 2010, and deployed 2011/2012 the project would, even in this early demonstration phase, produce enough clean and green electricity each year to meet the annual demand of between 2,500 and 3,000 homes, subject to grid connection. This clean generation will offset the release of about 1,000 tonnes of carbon dioxide every year, the main greenhouse gas contributing to global warming and climate change. However, there may be limits placed on us by the local grid capacity, and we are in discussion with Western Power as to exactly how much energy we can bring ashore.

The demonstration site has been selected in order to meet several criteria. It must be exposed to the predominant wind and wave direction but relatively close to land, for economic and operational purposes. The site must be close to a major port, in our case Milford Haven, but yet away from commercial shipping interests and outside of military firing ranges. The landfall of the cable must be close to potential grid connection locations. Due to these practical limitations, the demonstration site is located within the Pembrokeshire Marine SAC (Special Area of Conservation), and a full Environmental Impact Assessment (EIA) has being conducted. However, we are only applying for permission to use this site as a test area and the Wave Dragon will only remain in place here for three to five years, covering an area of approximately 0.25 km2, before being removed; hopefully to join ten other units further (ten to twelve miles) out to sea, to form Britain’s first commercial wave energy farm.

How it works:

The Wave Dragon is large floating barge that produces energy directly from the power of the water; the only moving parts in the entire structure are the turbines. The Wave Dragon works by facing its outstretched collector arms towards the oncoming waves, these concentrate 300 metres of wave front
towards 140 metres of ramp at the front of the structure. This focusing increases the wave height at the ramp, which in turn acts like a beach and causes the waves to break over its top and into the reservoir behind it. By this action the water is elevated and given potential energy, which is turned into electricity by simply running the water down through turbines in the bottom of the structure. The Wave Dragon actually produces energy in almost exactly the same way as a low-head hydro power station. This last fact is one of the major advantages of the Wave Dragon concept. There is no new technology utilised in this structure at all. The low-head turbines we are using are the same as the hydropower industry have been successfully using for over 80 years, the structure its self is based on designs that the maritime world has been using for even longer. This is of course another huge benefit of deploying in Pembrokeshire, in that there is a major resource of maritime construction experience that exists within Milford Haven and Pembroke Dock.

Wave Dragon Ltd:

Wave Dragon is a private company working towards the commercialisation of a technology to extract electricity directly from ocean waves. Originally a Danish company we are now moving the centre of our global operations to South Wales to take advantage of both the Wave Climate and the professional expertise in this area and especially the political commitment to renewable energies by the Welsh Assembly Government.
