Cogeneration thermal energy

Another example of a topping cycle cogeneration system is one based on recovering the thermal energy exhausting from a gas turbine/generator. 

Cogeneration is an energy conversion process wherein heat from a fuel is simultaneously converted to useful thermal energy (e.g., process steam) and electric energy. The need for either form can be the primary incentive for cogeneration, but there must be opportunity for economic captive use or sale of the other. In a chemical plant the need for process and other heating steam is hkely to be the primaiy in a pubhc utility plant, electricity is the usual primary produc t. 

Industrial use of cogeneration leads to small, dispersed electric-power-generation installations—an alternative to complete reliance on large central power plants. Because of the relatively snort distances over which thermal energy can be transported, process-heat generation is characteristically an on-site process, with or without cogeneration.

In the United States, in the commercial sector, the most attractive application for near-term fuel cell technology is onsite cogeneration. In this application, the fuel cell power plant is located at the site of the end user, providing both electric and thermal energy. On-site applications in the commercial... 

Stationary power is the most mature application for fuel cells. Stationary fuel cell units are used for backup power, power for remote locations, stand-alone power plants for towns and cities, distributed generation for buildings, and cogeneration where excess thermal energy from electricity generation is used for heat. 

Combined heat and power (CHP) (Cogeneration) -The thermal energy created while converting fuel to electricity would be utilized for heat in addition to electricity in remote areas and electricity and heat for sites that have a 24 hour thermal/electric demand.
