Wyatt – 2 Abstract As natural resources are being depleted exponentially, scientists are looking for new forms of energy from renewable sources. Scientists have developed a new energy source called Oceanic Thermocline Energy. This energy uses the energy given off by water or other renewable sources when it changes from liquid states to gas states and then back again into the liquid state. A closed-cycle system, where only water is used, can provide drinkable water to areas with limited supplies. Oceanic Thermocline Energy is a renewable energy that also provides clean drinking water, and therefore should be considered for future use.

Wyatt – 4 1.0 Introduction Scientists have developed a renewable energy called Oceanic Thermocline Energy (OTE). OTE heats warm surface water from the ocean until it is a steam. An external heat source is required to heat the water. The steam runs through a generator that collects the energy, after which the steam is condensed into a liquid state by adding colder water from the deep ocean. The phase change in water provides the energy for this system and can be repeated multiple times, especially in the case of ocean water. OTE sources are used instead of fossil fuels, which are expected to be depleted within the next fifty years. The source of energy is water, which can be reused within this system. This paper explains thermocline energy, specifically the way that the extraction of oceanic thermocline energy works, the practicality of this type of energy, and what it would take to begin using this type of energy. Other types of oceanic energy will not be reviewed. Oceanic Thermocline Energy is important because energy sources are quickly being depleted and renewable energy sources are desperately needed.
