Wave energy potential in Bangladesh

Bangladesh has one of the highest population densities and the lowest per capita energy consumption of the world. Energy resources are very limited, the main natural resource being gas.
The coastline is open to the main wave source from the Bay of Bengal and the generation of electricity from such waves could be an important source for Bangladesh and in addition could ease the problems of wave action on the coastline.

Wave heights have been recorded at Patenga (Chittagong) by a wave rider buoy and related to wind date. Maximum wave heights of over 2 m, with a maximum of 2.4 m were recorded.
The Ministry of Shipping in Bangladesh has recently started recording wave heights, wave periods, wave direction and so on at the mouths of 2 of the main river systems.
Automatic hydromagnetic current meters and wave recorders, type-S4 have been installed at 2 stations to take the readings of current and waves.
Possible power output at the Pussur river has been estimated. It is observed that the output power varies from 26 kW/m to 98 kW/m.

There are many possible wave power plant sites at the south coastal belt of Bangladesh with a good wave climate. Among them the south west of Cox's Bazar, Moheskhali island, Kutubdia island, Sandwhip island and the Hiron point are very prominent sites. It would be necessary to operate a wave power station in a stand alone mode. While not offering a continuous supply of electricity they could provide a vast improvement on what exists at present.

Wave power plants at the suggested sites, would reduce damage on the coastlines and could create better employment opportunities through the installation of new industries and the production of more crops.
