Available in PDF, EPUB and Kindle. Book excerpt: In 1980, the Westinghouse Corporation completed an extensive Claude open-cycle ocean thermal energy conversion (OC-OTEC) system design study. Since that time, the Solar Energy Research Institute (SERI) has produced concepts and data bases that have reduced the technical uncertainties associated with the evaporator and condenser design and performance, seawater sorption kinetics and gas removal systems, low pressure turbine design with novel materials, and low cost system containment and structural design. This paper describes an integrated system design case study using the improved data base and summarizes an assessment of the relative thermodynamic performance of advanced technologies, drawing parallels with Claude's early work in the 1930s. Projections from these latest advances imply that OC-OTEC systems can be cost effective in sizes less than 10 MWe. Analyzing the research needs for OC-OTEC systems reveals that an experimental facility integrating all essential components of a system is required. This paper describes a facility for conducting advanced research and verifying cycle feasibility in terms of performance, reliability, and cost. The thermodynamic performance of this integrated design is projected using an analytical system model incorporating the highly coupled component interactions.

Available in PDF, EPUB and Kindle. Book excerpt: The 21st century is characterized as an era of natural resource depletion, and humanity is faced with several threats due to the lack of food, energy, and water. Climate change and sea-level rise are at unprecedented levels, being phenomena that make predicting the future of ocean resources more complicated. Oceans contain a limitless amount of water with small (but finite) temperature differences from their surfaces to their floors. To advance the utilization of ocean resources, this book readdresses the past achievements, present developments, and future progress of ocean thermal energy, from basic sciences to sociology and cultural aspects.

Book Synopsis An Evaluation of the U.S. Department of Energy's Marine and Hydrokinetic Resource Assessments by : National Research Council
Download or read book An Evaluation of the U.S. Department of Energy's Marine and Hydrokinetic Resource Assessments written by National Research Council and published by National Academies Press. This book was released on 2013-04-23 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing renewable energy development, both within the United States and abroad, has rekindled interest in the potential for marine and hydrokinetic (MHK) resources to contribute to electricity generation. These resources derive from ocean tides, waves, and currents; temperature gradients in the ocean; and free-flowing rivers and streams. One measure of the interest in the possible use of these resources for electricity generation is the increasing number of permits that have been filed with the Federal Energy Regulatory Commission (FERC). As of December 2012, FERC had issued 4 licenses and 84 preliminary permits, up from virtually zero a decade ago. However, most of these permits are for developments along the Mississippi River, and the actual benefit realized from all MHK resources is extremely small. The first U.S. commercial gridconnected project, a tidal project in Maine with a capacity of less than 1 megawatt (MW), is currently delivering a fraction of that power to the grid and is due to be fully installed in 2013. As part of its assessment of MHK resources, DOE asked the National Research Council (NRC) to provide detailed evaluations. In response, the NRC formed the Committee on Marine Hydrokinetic Energy Technology Assessment. As directed in its statement of task (SOT), the committee first developed an interim report, released in June 2011, which focused on the wave and tidal resource assessments (Appendix B). The current report contains the committee's evaluation of all five of the DOE resource categories as well as the committee's comments on the overall MHK resource assessment process. This summary focuses on the committee's overarching findings and conclusions regarding a conceptual framework for developing the resource assessments, the aggregation of results into a single number, and the consistency across and coordination between the individual resource assessments. Critiques of the individual resource assessment, further discussion of the practical MHK resource base, and overarching conclusions and recommendations are explained in An Evaluation of the U.S. Department of Energy's Marine and Hydrokinetic Resource Assessment.

Download or read book Results of Scoping Tests for Open-cycle OTEC (ocean Thermal Energy Conversion) Components Operating with Seawater written by and published by . This book was released on 1990 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents comprehensive documentation of the experimental research conducted on open-cycle ocean thermal energy conversion (OC-OTEC) components operating with seawater as a working fluid. The results of this research are presented in the context of previous analysis and fresh-water testing; they provide a basis for understanding and predicting with confidence the performance of all components of an OC-OTEC system except the turbine. Seawater tests have confirmed the results that were obtained in fresh-water tests and predicted by the analytical models of the components. A sound technical basis has been established for the design of larger systems in which net power will be produced for the first time from OC-OTEC technology. Design and operation of a complete OC-OTEC system that produces power will provide sufficient confidence to warrant complete transfer of OC-OTEC technology to the private sector. Each components performance is described in a separate chapter written by the principal investigator responsible for technical aspects of the specific tests. Chapters have been indexed separately for inclusion on the data base.

Book Synopsis Conceptual Design of an Open-cycle Ocean Thermal Energy Conversion Net Power-producing Experiment (OC-OTEC NPPE). by :
Download or read book Conceptual Design of an Open-cycle Ocean Thermal Energy Conversion Net Power-producing Experiment (OC-OTEC NPPE). written by and published by . This book was released on 1990 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the conceptual design of an experiment to investigate heat and mass transfer and to assess the viability of open-cycle ocean thermal energy conversion (OC-OTEC). The experiment will be developed in two stages, the Heat- and Mass-Transfer Experimental Apparatus (HMTEA) and the Net Power-Producing Experiment (NPPE). The goal for the HMTEA is to test heat exchangers. The goal for the NPPE is to experimentally verify OC-OTEC's feasibility by installing a turbine and testing the power-generating system. The design effort met the goals of both the HMTEA and the NPPE, and duplication of hardware was minimal. The choices made for the design resource water flow rates are consistent with the availability of cold and warm seawater as a result of the seawater systems upgrade carried out by the US Department of Energy (DOE), the state of Hawaii, and the Pacific International Center for High Technology Research. The choices regarding configuration of the system were made based on projected performance, degree of technical risk, schedule, and cost. The cost for the future phase of the design and the development of the HMTEA/NPPE is consistent with the projected future program funding levels. The HMTEA and NPPE were designed cooperatively by PICHTR, Argonne National Laboratory, and Solar Energy Research Institute under the guidance of DOE. The experiment will be located at the DOE's Seacoast Test Facility at the Natural Energy Laboratory of Hawaii, Kailua-Kona, Hawaii. 71 refs., 41 figs., 34 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Researchers at the Solar Energy Research Institute (SERI) conducted systems analysis studies to determine the potential of various experiments to produce net power using the Claude open-cycle ocean thermal energy conversion (OTEC) power system. The proposed experiment test site is to be the Natural Energy Laboratory of Hawaii at Keahole Point. We found that net power is unlikely to be produced in experiment sizes that use less than about 195 kg/s (3000 gpm) of cold water, and the flow rates of 420 kg/s (6500 gpm) are necessary to achieve a net-power production of at least one-half the gross-power output of the experiment.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical oceans with a 20 degrees C or more temperature difference between surface and deep water represent a vast resource of thermal energy. One of the methods of harnessing this resource is an open-cycle Ocean Thermal Energy Conversion (OTEC) system utilizing steam evaporated from the surface water for powering the turbine. In this paper, the state of the art of heat and mass transfer as they relate to evaporation and condensation of steam at low pressures, both in direct contact with seawater and in surface condensers, is summarized, and relevant research issues are discussed.
