CHP: Efficient way to generate electricity and heat together: The definition of CHP or cogeneration implies that heat and electricity are produced simultaneously in one process. In CHP production intermediate fluids, either hot steam or exhaust gases are used first in electricity generation after which the remaining heat is recovered and not emitted to the environment. If some part of the intermediate fluid or the remaining thermal energy is ejected to the environment without heat recovery, the portion of the electricity generation corresponding to this part is by default not CHP electricity. In separate electricity generation the conversion efficiency is between 35-55%, but in cogeneration plants overall efficiencies as high as 80-90% can be achieved by using the remaining thermal energy to produce heat either for industrial processes or district heating. The energy savings potential of cogeneration is important in reducing CO2 emissions, improving energy efficiency and reducing dependence on imported energy in New Jersey. |
