Lockheed Martin's Alternative Energy Development team has partnered with Makai Ocean Engineering to complete the final design phase of a 10MW closed cycle OTEC pilot system which planned to become operational in Hawaii in the time frame. This system was designed to expand to 100MW commercial systems in the near future. Low Risk: Conventional Closed Cycle OTEC is a lowrisk. The problem with this remarkable renewable energy is cost. At present, OTEC plants can be built that will be Systems Optimization for an Integrated Ocean Thermal Energy Conversion (OTEC) Plant Wrote software to technically& economically combine diverse deep optimization of a closed-cycle otec system pdf OTEC works basically by two cycle systems known as open cycle system and closed cycle system. Closed cycle OTEC system Figure 1. 1 The ultimate goal of algorithm is to allow rapid optimization of varying OTEC plant configurations in order to minimize capital cost.

H. Aydin, Performance Analysis of A Closedcycle Ocean Thermal Energy Conversion System With Solar Preheating and Superheating, (Thesis), University of Rhode Island, 2013. optimization of a closed-cycle otec system pdf The siting of an OTEC plant, either onshore or offshore, represents one of the key decision for any proposed project. The other key decision is the type of cycle to use. There are two principle options, an open cycle plant or a closed cycle plant. As the temperature in the top surface is equal to the ambient temperature and the temperature in the bottom surface is much cooler when compared to the top surface, there exists a temperature difference between the layers of the ocean and this temperature difference is utilized to run an OTEC power plant. Ocean Thermal Energy Conversion (OTEC) is a process that can produce electricity by using the temperature difference between deep cold ocean water and warm tropical surface waters. OTEC plants pump large quantities of deep cold seawater and surface seawater to run Optimization of an ocean thermal energy conversion (OTEC) system is carried out by the Powell method (the method of steepest descent).
