The Foundation for Scientific and Industrial Research (SINTEF) in collaboration with some other entities like the companies MARINTEK, Kvernevik Engineering AS and Havkraft AS, have turned a small fishing boat into a power plant. The boat is in the norwegian city of Ålesund with the objective of generating electricity by using the power of the waves.
The project have been developed during two years and the system is based on four big chambers located in the prow of the boat. When the waves hit the boat, the water level increases inside of the chambers and consequently the air pressure increases, which moves the turbines inside of the chambers. Moreover, the movement of the boat contributes to the increase in the air pressure in the chambers when the waves are big. The design of the chambers allows to take advantage of waves of many different heights, so the waves energy is used in a very effective way.
In order to produce energy, it is enough to leave the boat anchored in an area with enough waves since the whole system is made to be controlled from inland. The nominal capacity of the power plant (the design capacity) is 20 kW and according to MARINTEL, the boat will be able to produce 320.000 kWh yearly.
