Constraints Affecting the Utilization of OTEC Technology in Island Countries such as Jamaica

Jamaica is a typical example of an oil-importing developing country for which OTEC technology is an attractive energy source. Suitable bathymetric conditions and the required temperature difference between surface and sub-surface oceanic waters exist nearshore because of the narrow shelf and steep slope around most of the island´s northern and eastern coastline. Constraints affecting Jamaica´s ability to utilize OTEC are primarily technological, financial, economic, and strategic in nature. For OTEC to be a practical energy alternative for Jamaica and other tropical countries two or more small plants in the range of 5 - 10 MW should be built and operated early to demonstrate the cost efficiency and longevity of OTEC systems. In tandem with energy production these plants should, where applicable, produce fresh water or be allied to mariculture.
