Wave energy

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work ? for example, electricity generation, water desalination, or the pumping of water (into reservoirs). A machine able to exploit wave power is generally known as a wave energy converter (WEC).

  • Beach nourishment

    Type: 
    Technology
    Sectors:
    Objective:

    Beach nourishment is an adaptation technology primarily used in response to shoreline erosion, although flood reduction benefits may also occur. It is a soft engineering approach to coastal protection which involves the artificial addition of sediment of suitable quality to a beach area that has a sediment deficit. Nourishment can also be referred to as beach recharge, beach fill, replenishment, re-nourishment and beach feeding. The description of this technology originates from Linham and Nicholls (2010).

The EWP converters draw energy from wave power throughout uniquely shaped floaters The Wave Clapper and the Power Wing that rise and fall with the up and down motion lifting force change of water level hydraulic air lock and incident flux of waves.

  • Offshore Energy Harvesting Storage and Power Generation System

    Type: 
    Product
    Technology:

    Problem: Intermittency of wind energy supply from wind turbines Technology: This invention is a system for simultaneously anchoring floating offshore energy harvesting machines such as wind turbines and wave energy machines storing excess energy harvested and then generating continuous power to meet baseload demands. It consists of a subsea structure with a chamber that is anchored to the seafloor by either gravity or piles to resist mooring cable loads on the supporting floating structure used for the energy harvesting machines. The chambers are constructed from precast concrete.

  • Hollow Fiber Membranes for Osmotic Power Generation via Pressure Retarded Osmosis (PRO)

    Type: 
    Product
    Objective:
    Technology:

    Technology Overview: Osmotic energy is a completely renewable source that utilizes the mixing entropy of two solutions with different salinity. In the 1970s pressure retarded osmosis (PRO) as a membrane-based separation process was proposed to extract the osmotic energy from the sea. In this process water is drawn naturally from a low salinity feed solution across a semi-permeable membrane to a pressurized high salinity draw solution; power is then obtained by depressurizing part of the diluted draw solution through a hydroturbine.
