In a greenhouse electricity is needed in order to use, for example, assimilation lightning. The side-products that arise, heat and CO2, can be used to heat the greenhouse and provide it with CO2. By cogeneration (COGEN), each energy flow is almost fully utilized. This in contrast to a boiler or power plant, where a lot of residual heat will get lost.

The functioning of a cogeneration

A cogeneration generates electrical energy. This electrical energy is converted into thermal energy (heat) and light. Thermal energy and electrical energy are thus generated simultaneously. An COGEN consists of an engine, generator and heat exchangers. The fuel for a cogeneration is natural gas. The engine and generator generate electrical power, where after heat exchangers transfer the heat from the cogeneration to the heating system. The exhaust gases which occur during the combustion of natural gas will be handled and filtered later on in the exhaust path. As a result, the exhaust gases are clean enough to be dosed into the greenhouse (CO2 enrichment).

Lower total energy costs by cogeneration

The biggest advantage of cogeneration is that the energy is utilized better by the combined generation of heat and electricity. As a result, there is less fuel needed. This provides financial benefits. Besides that, lower fuel consumption has also the advantage that there are fewer harmful emissions.

Enerdes cogeneration

Enerdes designs and delivers cogeneration integrations whereby thermal energy and electrical energy is generated simultaneously. This creates a high total return of approximately 96.5%. We are happy to advise you about the benefits of COGEN in your specific situation.
