The South Pacific region spreads over tens of millions of square kilometers of ocean with immense potential for ocean energy such as wave energy, tidal current energy and ocean thermal energy. The land-mass for the countries in this region is very small compared to the total area; for example, for a country Kiribati, this area is more than 4000. Moreover, the geographical layout of the region with scattered islands and unavailability of power grid requires tailor-made solutions. In this scenario, waves and tidal currents have a very strong potential for becoming a sustainable source of power. At some of the locations with good waves, long term measurements are performed with a plan to extract energy. Some of the remote islands have severe shortage of water and it is planned to obtain desalinated water using wave-powered desalination systems. There are hundreds of small islands and a large number of reef openings, passages and sea-connected rivers where there are strong bi-directional currents. ADCP measurements are completed at some of the locations and some more are in progress/in the pipeline. The ongoing work includes development of new wave energy conversion devices such as an innovative concept of a rectangular OWC designed to direct the bi-directional flow onto the blades of a Savonius rotor, and the rotors driven by the orbital motion in waves. The other work involves design of blade sections and blades for tidal current turbines as well as computational study of cross-flow turbines for tidal current power generation.
