Netherlands: IDC Greenhouse as Energy Source project prolonged
Researchers Feije the Black, Jan Janse and Frank Kempkes gift more information on the plans last week. The Ministry of Economic Affairs and the Horticultural Agency are funding this research Within the framework of the program Greenhouse as Energy Source. The IDC Greenhouse as Energy Source is a place where the latest technology is tested and Shown to the sector. The aim is to develop powerful Therefore greenhouse concepts where a sophisticated production is combined with a minimum consumption of fossil energy.
The principles of the IDC are:
- Adjust the greenhouse climate to the needs of the plant.
- Keep the greenhouse closed in the winter season as much as possibleness, through active Dehumidification with recovery of sensible and latent heat.
- Make good use of shading screens with different properties.
- Use air movement to Realize high humidity, gested Minimizing Vaporization consistently the heating season.
- Use low-grade heat. Rarely will the water be hotter than 40 ° C and never hotter than 50 ° C.
- Base the heating on the heat pump with a small CHP (50-150 kW per hectare). This combination represents entry the highest conversion efficiency of primary energy to Economically valuable commodity (heat, electricity and CO2 on crop growth).
- Make maximum use of sunlight and make the diffuse sunlight, So That the plant can utilize light more efficiently.
Expected result
The final energy consumption of greenhouses in the IDC Greenhouse as Energy Source:
Next Generation Semi Closed greenhouse: 18 m³ natural gas per m² per year
VenlowEnergy greenhouse: 12 m³ natural gas per m² per year
Daylight greenhouse: 6 m³ natural per m² per year
