The heat produced is used to heat the water for the heating pipes;
The electricity produced can be used internally, e.g. for supplementary lighting, or sold to the grid;
The CO2 produced is supplied to the greenhouse to be used by the crops.
Contribution to energy balance and resource use of greenhouses:
The CHP supplies heat to the water running in the heating pipes, which adds energy to the greenhouse.
...
As a by-product of the CHP process, CO2 can be supplied to the greenhouse.
Possible steps towards sustainable fossil-free greenhouses
As the basis of the CHP process is fossil fuels, there is a limit on how sustainable this installation can be made. However, the energy generated in excess over the greenhouse energy demand can be stored in a buffer tank for later use, outside the CHP operating hours.
