Company Profile:
The process of storing, or converting energy from one form to another, for later use; storage devices and systems include batteries, conventional and pumped storage hydroelectric, flywheels, compressed gas, and thermal mass.
Industry:Energy
The process of the absorption of heat from one location and its transfer to another for rejection or recuperation.
Industry:Energy
The process of transmitting electricity over one or more separately owned electric transmission and distribution systems. (See Wholesale and Retail Wheeling.)
Industry:Energy
The process of using heat that is rejected in one part of a cycle for another function or in another part of the cycle.
Industry:Energy
The process or technologies for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and that of ocean depths. Warm surface water is pumped through an evaporator containing a working fluid in a closed Rankine-cycle system. The vaporized fluid drives a turbine/generator. Cold water from deep below the surface is used to condense the working fluid. Open-Cycle OTEC technologies use ocean water itself as the working fluid. Closed-Cycle OTEC systems circulate a working fluid in a closed loop. A working 10 kilowatt, closed-cycle prototype was developed by the Pacific International Center for High Technology Research in Hawaii with U.s. Department of Energy funding, but was not commercialized.
Industry:Energy
The processes that a work input/output system undergoes and in which the initial and final states are identical.
Industry:Energy
The product of 1 hour, and usually the number of degrees Fahrenheit the hourly mean temperature is above a base point (usually 65 degrees Fahrenheit); used in roughly estimating or measuring the cooling load in cases where processes heat, heat from building occupants, and humidity are relatively unimportant compared to the dry-bulb temperature.
Industry:Energy
The production of an electric current in a conductor by the variation of a magnetic field in its vicinity.
Industry:Energy
The production of electrical current from light.
Industry:Energy
The production of energy by a system or appliance at a level less than its design or nominal capacity.
