5.6.2 Wave Power Plants

A promising source of renewable energy sources are waves of the oceans, seas and large lakes that can develop the greatest specific power, among others renewable energy sources. The waves of all oceans, sees, and big lakes in the future are able to provide up to 2 TW of electric power, enough to meet the needs of all mankind. With the present level of technology, wave power plants (WavePP) with a total capacity of up to 10 billion kWh can be created.

The trend in the development of WavePP as power plants using other energy renewable resources—a complex of single intermediate power modules (approximately 1 MW). A WavePP module has a size of about 50 m along the wave front. Complexes with hundreds of meters in size and the total capacity of tens of megawatts are often constructed of these modules. The low-power modules (tens of kilowatts) with a sufficiently broad consumer niche had been developed. As in the case of tidal energy, a number of technical solutions currently proposed and partially implemented can be grouped into two groups faced on prevalence of kinetic energy or energy rolling surface, which is converted into electrical energy. By design, WavePP can be divided (rather conventionally) on the float-WavePP and chamber-WavePP. The principles of their work are shown in Figs. 5.18 and 5.19, respectively.
