Solar energy is a sustainable way of generating energy. It never runs out and no CO2 is emitted when solar energy is converted into electricity. That is why we have invested a lot in solar panels in recent years. The roof of the packaging hall and storage area in De Lier was made suitable for solar panels, and a total of 1551 solar panels were installed in various phases. The roof at our second location in ‘s-Gravenzande was also made suitable, and 394 solar panels were installed there. The 1945 solar panels generate an average of 555,000 KWh of energy in one year, which is equivalent to the annual consumption of 200 households and approximately 70% of our annual consumption. And with our membership of the Maasdijk heat cooperative we are also affiliated to Geothermal Heat Maasdijk.
Cooperation with Maasdijk Geothermal Heat Cooperative
We are also affiliated to the Maasdijk Geothermal Heat Cooperative through our membership. The Maasdijk Heat Cooperative is a cooperation of growers who endorse the need for sustainability and wish to work together to make this possible. Together they are looking for affordable alternatives which will reduce the use of fossil fuels. It is a collaboration of more than 80 greenhouse horticulture companies with approximately 400 hectares of land in Maasdijk, s-Gravenzande and De Lier.
Geothermal Heat Maasdijk is a cooperation between heat cooperative Maasdijk and HVC with the aim of stimulating and realising sustainable heat for and with greenhouse companies in the Westland, including for our greenhouses in De Lier and Maasdijk. The project has been running for a number of years, and last week Pieter Varekamp, alderman for energy transition of the municipality of Westland, gave the go-ahead for the project. For more information about the planning and the activities in the near future, watch the video on the following link: https://www.aardwarmtemaasdijk.nl/nieuws/meer-over-de-planning-en-werkzaamheden
When extracting geothermal heat, two wells are needed, a so-called doublet. In the one well, hot water is pumped up and the heat from this water is transferred via heat exchangers to a local heat network. In the other well, the cooled water is returned to the ground. The heat is then distributed to greenhouses and buildings by the local heat network.
The video and photos below show that last week they started laying the 380 metre long heat pipes. These pipes are needed to connect all the heat sources of the Warmtesysteem Westland. Warmtesysteem Westland is a local heat network that connects various heat clusters, such as geothermal heat Maasdijk, so that heat can be exchanged. Ultimately, our greenhouses will also be connected to this heat system.
