Currently, there are four cultivation locations in Southwest Netherlands where our company operates.
Site Oosterland has a total area of 6.5 hectares. Together with some other greenhouse farms, we use local biomass. We not only take heat, but also extract CO2 from the flue gases and blow it into the greenhouses. For this project, we are united with DES B.V.
Duurzame Energie Sirjansland, DES B.V. was founded to make the energy supply of the participating horticultural companies more sustainable and to expand sustainability in the future where possible. Following the biomass, we use a CHP: a CHP is a gas turbine that generates electricity. Our impact on the environment is therefore very low.
This site has a total area of 8.5 hectares. We use a system here that preserves heat. It consists of two CHPs and two heat pumps, supplemented by aquifers. The CHP emits low-grade hot air (±30Co) through the chimney. This heat is not lost, but is stored in the ground using an aquifer, at a depth of 80 meters. In winter, we bring this heat back up, raise the temperature to 45 degrees via heat pumps, and use it for our heating system.
The heat pumps are powered by electricity and can produce 1MWh of heat. We are also working on, among other things, the Osiris project in which 100 million cubic meters of natural gas per year can be saved by 17 horticultural companies.
