Accesible cogeneration technology can be deployed quickly, cost-effectively, and with few geographic limitations. Cogeneration can use a variety of fuels, both fossil and renewable. It has been employed for many years, mostly in industrial, large commercial, and institutional applications.
Combined heat and power (CHP) integrates the production of usable heat and power (electricity), in one single, highly efficient process.
CHP generates electricity whilst also capturing usable heat that is produced in this process. This contrasts with conventional ways of generating electricity where vast amounts of heat is simply wasted. In today’s coal and gas fired power stations, up to 2/3 of the overall energy consumed is lost in this way, often seen as a cloud of steam rising from cooling towers.
Cogeneration “CHP” – Onsite renewable Power
CHP may not be widely recognized outside industrial, commercial, institutional, and utility circles, but it has quietly been providing highly efficient electricity and process heat to some of the most vital industries, largest employers, urban centers, and campuses in the United States.
Why Cogenerate ?
The main aspect of what makes cogeneration an advantageous technology is that is a proven and reliable method of improving energy efficiency that helps create jobs and benefit our environment. Making use of the heat that was once lost in power generation process our environment can benefit from the former ways of power generation by helping us preserve non-renewable resources of energy.
The efficiency factor
By using waste heat, CHP plants can reach efficiency ratings in excess of 80%. This compares with the efficiency of gas power stations, which range between 49% and 52%. Coal-fired plant fare less well with an efficiency of around 38%.
CHP plants provide local heat, electricity and sometimes even cooling to various types of users. Because the energy is produced locally, CHP has the added benefit of avoiding efficiency losses incurred through transmission and distribution of electricity through the National Grid and local distribution networks. Around 7% of energy would usually be lost when the network is used to transport energy from the generation source to the user.
