For a successful operation of a greenhouse complex a defined microclimate for the plant growth is needed. To increase production yield CO2 is used as nutrient substrate for plant growth. Special co-generation plants may boost greenhouse efficiency since they are capable to produce electric energy, heat and cold, as well as the needed carbon dioxide.
The use of carbon dioxide from exhaust gases of a stationary gas engine requires an effective removal of impurities like CO, NOx, CH, HCHO, C2H4, which are not only dangerous for the people working in the green house but also are effective poisons for the plants. Thus, a catalytic treatment system including SCR (Selective Catalytic Reduction) is needed for a significant reduction of this substances. Emission Partner does offer this kind of systems enabling the operator of a greenhouse to use exhaust gases for his benefit.
No doubt, the catalytic treatment system means a capital investment and also an increase for operating costs but the economic benefits justify such an investment.
Depending on the plant type an average harvest increase from 15 % up to 70 % with 800-1000 ppm CO2 can be achieved.
Summarizing the benefits of a co-generation unit with catalytic treatment system would be following:
