The province of South Holland is teaming up with several research institutes and greenhouse companies to explore Medium Temperature Storage (MTS). Levoplant is one of five growers taking part in this pilot project, which will run until 2028. At their Bospolder location, a test drilling will soon take place, and the company expects to start using MTS heat of up to 50 degrees Celsius in the near future. Their newest orchid facility has just been renovated, and as of today, the plants are already in the greenhouse.
For greenhouse horticulture, MTS offers a big step forward compared to traditional heat-cold storage systems. While conventional systems can only store heat at around 25°C, MTS allows storage up to 50°C. This makes energy use much more efficient, while cutting both costs and CO₂ emissions.
Ron Fransen, director of Levoplant, explains: "This major leap in temperature storage not only allows us to use energy more efficiently, but also leads to significant cost savings and a meaningful reduction of our CO₂ footprint."
The pilot phase will test whether this method is safe for groundwater and soil, while also showing how much it can contribute to energy savings across the greenhouse sector.
🔬The province, together with greenhouse horticulture companies and knowledge institutions, is researching sustainable energy technology Medium Temperature Storage (MTS): storing heat in the ground for later use. Is this safe for soil and groundwater, and how can it contribute to energy savings.♻️ pic.twitter.com/ocGHvSL0Fw
