Combined heat and power production (CHP), or simply “cogeneration”, applied in the commercial sector offers a wide spectrum of benefits. Such commercial CHP systems have been installed successfully in a range of different applications including office buildings, retail stores, airports and shopping malls.

The same applies to the industrial sector, as cogeneration systems offer a range of potential benefits to industrial applications. Gas engine cogeneration systems can significantly reduce operational costs related to fuel consumption, used to produce electricity and heat. Tax policy in some countries is beneficial to the owners of combined heat and power plants.

 

Power supply with stability and flexibility

 

The natural gas supply from the local network can be used in the gas engine-based cogeneration systems providing a stable supply of electrical power. When needed, power supply can be isolated from the local electricity grid and serve the local loads of the facility. The heat produced by the engine can be recovered either as hot water or as steam for use by surrounding operations. Moreover, the recovered heat can be fed into an absorption chiller to produce a source of cold water, if there is a local need for cooling loads. This cold water can in turn be used to support a refrigeration or air conditioning system. Such systems, providing electricity, heat and cooling, are called trigeneration plants. A further step in cogeneration applications is carbon dioxide recovered and scrubbed from the engine exhaust for industrial users that require carbon dioxide. There are various applications for this carbon dioxide including ones in the food and drinks industry.
