What makes CHP in greenhouses so attractive ?
Exhaust gas of gas engine– produces CO2 , heat and electricity
– separated product CO2, heat and electricity– cleaned CO2 (NOx, CO, C2H4..)
50 % Less heat compared to boiler

J624 engines at Royal Pride Holland …
• Avoid primary energy input equivalent to the energy contained in over 64,000 barrels of oil
• Emit 14% less CO2 than would be emitted in the separate production of heat and electricity
Values are based on performance of two natural gas fired J624 CHP units, operating 8000OH/year, compared to separate production of heat by a gas boiler and the delivery of electricity on the European grid.

In one year of running at full capacity, the Royal Pride Holland J624s avoid the emission of over 4,800 metric tons of CO2 …
This equals to 2,400 cars on European roads or The amount of CO2 absorbed annually by more than 1,200 hectares of UK forest (= over 1,600 FIFA soccer fields)
Values are based on performance of two natural gas fired J624 CHP units, operating 8000OH/year, compared to separate production of heat by a gas boiler and the delivery of electricity on the European grid.

Application benefits• Year round system efficiency will typically be at 90%.
• Implementing CHP in the greenhouse industry facilitates generation where the thermal loads are, which maximizes energy efficiency.
• CO2 captured during power production can be utilized in the greenhouse where plants absorb CO2 for production increase.
• Thermal energy produced during power production can be stored in existing thermal storage tanks and be utilized at other times of the day. Optimal flexibility.
• Project construction typically takes less than 12 months from date of go ahead.

Worldwide – GH Locations
Greenhouse activity all around the globe due to:
• Food & Water • Energy shortage / savings• Competition• Independency of foreign imports• Increase of quality & production. • Decrease of pesticide usage• Availability of surface• Employment
The demand for flexible power will grow.
Energy trading will become important toreduce production costs.
Greenports will be located close to the consumers.“ Local for Local”
From open bulk production to high tech hydroponics
