Survey of Energy Resources 2007
Wave Country Notes
Research into wave energy has been undertaken at the Norwegian University of Science and Technology (NTNU), Trondheim for the past 30 years and two full-size devices were deployed and operated successfully for a prolonged period during the 1980s. More recently two other devices have been developed.
The Seawave Slot-Cone Generator (SSG) concept is a shoreline wave-energy converter, based on the wave overtopping principle utilising three reservoirs placed on top of each other. Water captured in each of these reservoirs will then run back to sea through the multi-stage turbine. Multiple reservoirs are used to improve overall efficiency. A 200 kW pilot plant is scheduled to start construction in 2007 (www.waveenergy.no).
SEEWEC is a consortium involving 11 partners from 5 EU-members (Belgium, Netherlands, Portugal, Sweden and the UK) and 1 associated country (Norway). It aims to build the FO3, an array of buoys attached to a large floating structure with extensive use being made of composite materials (www.seewec.org). Plans have been made and consent received for 4 x 2.5 MW platforms to be installed in 55 m water depth off the Norwegian coast, in addition to deploying this technology on the Wave Hub (see the UK Country Note).
