Desalination AdvantageOTEC KeySpecifically OTEC development allows for mass production of freshwater and other minerals and industriesCross 2013 [Martin, Translator, former chef and marketeer, currently disabled. I write articles on food,, travel, politics, religion and technology. How an ocean thermal energy conversion (OTEC) plant works https://suite.io/martin-cross/67sw266 In an open-cycle OTEC plant, the warm surface water is used directly to make electricity. Surface seawater is forced to vaporize in a near vacuum created in a special pressure vessel. The vapour (steam) drives a low-pressure turbine generator to produce electricity in the same way as a closed-cycle OTEC plant. This steam is then condensed back into pure fresh water by passing the steam through an exchanger fed with cold water from the ocean deeps or by pumping it down into deep cold water before returning it to the surface. The salt and any other contaminants in the seawater are left in the pressure vessel, from which they can be extracted at regular intervals. The advantages of this type of cycle are that several benefits for the local community can be obtained from a single plant. Many tropical islands, such as the Cape Verde Islands, suffer from a lack of freshwater. An open-cycle plant would provide both power and freshwater, plus the sea salt, which in itself is a marketable commodity or which can be mined for minerals before sale as salt. The pure water generated is suitable for domestic purposes and irrigation as well as industrial processes such as electrolysis into oxygen and hydrogen for fuel cells to power a hydrogen economy. In Hawaii, the National Renewable Energy Laboratory, as it is now known, has developed a vertical-spout evaporator for converting warm seawater into steam for use in this type of plant. This significantly increases the efficiency of the water to steam conversion OTEC creates plenty of water(OTEC) 2013 [Ocean Thermal Energy Corporation Welcome to Ocean Thermal Energy: An Introduction http://www.environmental-expert.com/companies/ocean-thermal-energy-corporation-otec-42134 Fresh Water Production The associated production of large quantities of fresh water is one of the great attendant benefits of both Ocean Thermal Energy Conversion (OTEC) plants and Seawater Air Conditioning (SWAC) facilities. An OTEC plant can produce up to 800,000 gallons per day of fresh water per Megawatt (MW) of installed gross electric power capacity. Thus, a 5MW OTEC facility could potentially produce as much as 4 million gallons of fresh drinking water each day. Fresh water production in conjunction with OTEC and SWAC systems is also environmentally superior to traditional water production methods utilizing local surface water sources to feed the desalination units. This environmental advantage arises from the more efficient multi-use of the source water, as well as the extreme dilution of brine (water containing large amounts of salt), thus rendering such brine discharge concentrations nearly undetectable and harmless to the environment. With the world’s demand for fresh water growing rapidly, the economic opportunities and humanitarian benefits of this technology are substantial. Ocean Thermal Energy Corporation stands ready to meet that growing demand. OTEC prevents stoppages in energy unlike other renewable resourcesOak Ridge National Library 2009 [ORNL is a national multi-program research and development facility managed by UT-Battelle for the U.S. Department of Energy Power from the Sea http://web.ornl.gov/info/ornlreview/v44_3_11/article09.shtml "There are several compelling advantages to the system," says Klett. "First, it produces totally green energy; there are no by-products. It's also very much like geothermal, solar or wind power in that it does not take any fossil fuel to drive it, so costs are limited to construction and maintenance." In addition, Klett is particularly emphatic about the availability of OTEC power. He notes that consumers don't always understand that the only kind of "green" energy that is currently available as "base power"—power that is available 24 hours a day, 7 days a week—is geothermal. "With other renewables," he says, "when the wind stops, you don't have power. If it's a cloudy day, you don't have power. Even hydroelectric power is at the mercy of fluctuating water levels. OTEC can actually be used for base power." Estimates suggest that, in tropical latitudes, OTEC has the potential to generate 3 to 5 terawatts of power without affecting the temperature of the ocean or the world's environment. "That's more than the electric generating capacity of this country," he says. "If we can supply a large fraction of our base power needs with green energy, we can revolutionize power generation."

In the tropics, surface waters are above 80 o F, but at ocean depths of about 1,000 meters, water temperatures are just above freezing everywhere in the ocean. This provides a 45 to 50 o F temperature differen tial that can be used to extract energy from the surface waters[10]. The most optimistic expectations for OTEC predict a cost on the order of ten times greater than for conventional fossil sources. If OTEC can ever be made cost effective, India is ideally situated to use it, with its large length of coastline adjacent to the deep off - shore water of the Indian ocean The India OTEC program started in 1980 to install a 20 MW plant off the Tami Nadu coast and in 1982, an OTEC cell was formed in National Institute of Ocean Technology (NIOT). A preliminary design was also completed in 1984 for a 1 MW closed Rankine cycle floating plant with ammonia as working flui d. In 1997, Government of India proposed to establish a 1 MW gross OTEC plant. To develop this project, India researchers have been exploring the participation of international expertise for a joint research and development.
