Title: Prospects for Ocean Thermal Energy Conversion (OTEC) in the Pacific: ABSTRACT

Author(s): Lloyd F., Lewis, Kenneth R. McDonald

Article Type: Meeting abstract

Abstract:

Ocean Thermal Energy Conversion (OTEC) may be the most promising future electrical energy source for many of the Pacific nations located between 20°N and 20°S latitudes. Within this band are found the optimum physical, economic, social, and cultural conditions for OTEC development. Several of the island nation governments in this region have declared OTEC to be the preferred alternative to their existing fossil fueled power plants, the fuel for which is imported at a severe economic penalty. In addition to OTEC serving as the cornerstone of energy self-sufficiency, these nations are also attracted to the potential OTEC by-products including fresh water, mariculture, and cooling water. Their interest is also stimulated by the potential for industrial expansion an economic development based on the added electrical baseload capacity OTEC can provide. Many multi-island nations see OTEC as a modest-sized decentralized energy facility that could serve remote population centers not serviceable from large central power stations.

Many factors contribute to the prospects for OTEC development in the Pacific and there has been notable progress to date. Demonstration OTEC facilities have been built and tested in Hawaii and on Nauru. Designs, site surveys, and environmental assessments for commercial OTEC plants have been prepared for Guam, Tahiti, Okinawa, and Saipan. Planning for OTEC is underway in American Samoa, Palmyra, Yap, and the Marshall Islands. An ammonia-producing OTEC plantship has been proposed for grazing in the central Pacific. These projects illustrate the strong interest in OTEC development that is found throughout the central Pacific.
