With an estimated theoretical resource of over 30,000 TWh/yr [...]

Wave energy has the advantages of high density, renewability, and wide distribution, been highly valued by many coastal countries. The wave conversion device can convert into electric energy, which is great significance for alleviating problems such as crisis greenhouse effect. traditional only gain along heave direction, kinetic buoy not fully utilized. To improve utilization efficiency device...

Wave energy collected by the power take-off system of a Wave Energy Converter (WEC) is highly fluctuating due to the wave characteristics. Therefore, an energy storage system is generally needed to absorb the energy fluctuation to provide a smooth electrical energy generation. This paper focuses on the design optimization of a Hydraulic Energy Storage and Conversion (HESC) system for WECs. The ...

We examine numerically the conversion of barotropic tidal energy into internal waves by flow over an isolated seamount and over systems of periodically and randomly distributed 1100 m tall seamounts with Gaussian profiles. The simulations use the Massachusetts Institute of Technology general circulation model (MITgcm) to calculate for an infinitely deep ocean the dependence of the energy conver...
