File Thermal efficiency enhancement of Ocean Thermal Energy Conversion (OTEC) using solar thermal energy (PDF 512 kb) by bjelkeman, last updated: 2008-11-24 09:20:04
Ocean thermal energy conversion (OTEC) is a power generation system that utilizes small temperature differences between the surface and deep sea water. This paper describes the simulation results of the thermal efficiency of an OTEC plant that utilizes not only ocean thermal energy but also solar thermal energy as a heat source. This power generation system is termed SOTEC (solar and ocean thermal energy conversion). Simulation results of a 100- kWe SOTEC plant, in which the solar collector is installed in two configurations, are obtained and compared with those of an ordinary OTEC plant. The simulation result shows that the proposed SOTEC plant can enhance the annual mean thermal efficiency up to 1.5 times higher than that of the ordinary OTEC plant. 2006, YAMADA, HOSHI, IKEGAMI (9 pages).
File Energy from the ocean (PDF 2.5 Mb) by bjelkeman, last updated: 2008-05-02 10:43:17
Techniques of ocean thermal energy conversion are summarized, along with the development status of the required power system and ocean system components. The worldwide ocean thermal resource is assessed as a function of geography and time. Environmental impacts and siting considerations are treated. Diverse commercial market applications of OTEC are summarized, based upon the two key options for OTEC of providing electricity by submarine cable and of manufacturing energy-intensive products for shipment to dispersed markets. By-products of OTEC such as fresh water and nutrients for mariculture are discussed. 1982, Robert Cohen (33 pages).

Folder The OTEC Liaison by bjelkeman, last updated: 2006-05-21 21:40:36
The newsletter "The OTEC Liaison" was published from 1977 to 1983. Although old, these contain a lot of useful OTEC information. Richard Meyer of The Ocean Energy Council kindly donated a set of issues for us to add to the library. We are still scanning these, so not all issues are available online yet.

File OTEC sites (PDF 290 kb) by bjelkeman, last updated: 2005-08-16 08:59:50
OTECs can be sited anywhere across about 60 million square kilometers (23 million square miles) of tropical oceans-anywhere there is deep (and, therefore, cold) water lying under warm surface water. This document lists 99 potential shorebased OTEC sites with a brief discussion about each. November 1997 by Richard Crews (18 pages).
