The technology to exploit Wave Energy is still in its demonstration phase, after 30 years of R&D. However, contrarily to wind energy, where only one concept remained – one turbine with a horizontal axis with three blades – there still exist a large amount of concepts competing in wave energy. Tests on sea of pilot plants and prototypes Different wave energy exploitation systems have been tested at sea, both pilot plants and prototypes: OWC Pico Plant (WavEC, Portugal), Oyster (Aquamarinepower), Pelamis (Pelamis Wave Power Ltd, UK), OWC LIMPET Plant (Wavegen, United Kingdom), WaveRoller (AW-Energy Oy/Finland), AWS (AWS Ocean Energy, UK), Wave Dragon (Wave Dragon ApS/Denmark), Powerbuoy (Ocean Power Technologies/ USA), AirWAVE (Oceanlinx/Australia), AquaBuOY (Finavera Renewables/Canada), OEbuoy (Ocean Energy Ltd/Ireland), WaveBob (Wavebob Ltd/Ireland) and Wave Star (Wave Star Energy/Denmark). Other systems exists on a less developed phase, however may be tested at sea in the coming years. Today we witness a fast growing of industry interested in wave energy with new participants in this sector, some of which are multinational companies. On the other hand, in the last years and in several countries, new mechanisms have been taken place. For the investors it is important to acknowledge the technology, the several teams responsible for the development of the technology, expected capital costs for the first farm, i.e. acquire a global vision of the sector in order to make decisions for a possible involvement. WavEC’s role Since 2004, the WavEC has developed with some regularity reports addressed to companies interested in the existing opportunities of the wave energy market. The WavEC keep an actualized data base of all wave energy technologies e its state of development.
