On our 9-hectare cucumber farm, we have installed 3 CHP units. Each one consists of a motor which is linked to a generator which produces electricity. The electricity is either used in the greenhouse or fed into the grid. The cooling water from the motor heats the greenhouse. The smoke emitted is 100% scrubbed. The CO2 emitted is used to fertilize the cucumbers. So using CHP in horticulture offers several advantages. The three CHP units on our farm each have 2 MW of electrical capacity. They operate on the basis of the demand for heat and CO2 in the greenhouse. In summer, for instance, they run from sunrise to sunset to meet the greenhouse’s demand for CO2. The heat produced is stored in buffer tanks for use at night. Every year, the units each run for 5,000 hours. This means we produce a yearly total of 30,000 MWh.
