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).

SectorsObjectiveThe main objective of land claim is neither erosion nor storm reduction. The aim of land claim is instead, to create new land from areas that were previously below high tide. However, if land claim is designed with the potential impacts of climate change in mind, measures can be taken to reduce the exposure of these areas to coastal flooding. For example, in Singapore and Hong Kong, there are enforced minimum reclamation levels to account for future SLR.

SectorsObjectiveBeach 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).

As the quest for clean renewable energy intensifies the proposition of extracting energy from ocean waves sounds increasingly more attractive. The wave energy resource is recognized to contain the highest energy density among renewables and is virtually inexhaustible. Moreover unlike wind the wave climate is more predictable and is generally less intermittent. The primary waves of interest are those generated by the blowing of the winds which in turn are a product of differential heating of the earth. Therefore the wave energy may be considered as a concentrated form of solar energy.

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.
