Recent wave energy research in Sweden

Summary form only given. The main aim of the governmental wave energy program is to evaluate whether wave energy could contribute to the future Swedish energy supply, especially in light of the decision to eliminate nuclear power before 2010. In the IPS-buoy (Interproject Service AB) project, a prototype was built in 1979 and tests were carried out at sea in 1980 and 1981. In 1985 a smaller buoy for navigation purposes was tested. With respect to the hose pump concept, sea trials were carried out in 1983 and 1984. A small light-buoy was also tested in 1985. Calculated cost for large scale power plants is less than 4 cents/kWh. The wave rotor is a promising concept of which only small models have been tested
