The Program Board of Knowledge in your Greenhouse and the Ministry of LVVN have agreed on 12 new projects within the Greenhouse as a Source of Energy research program. Some projects have already started. Below are the approved projects.
The next three projects were co-funded by the Kennis in je Kas (Knowledge in your Greenhouse) (KijK) program:
Organic waste streams as a biogenic CO2 source (project number E24003)
The aim of this project is to investigate whether short-cycle organic residue streams such as plant leaves, champost (the residual product from mushroom production) and roadside grass can be used as alternative biomass to meet the biogenic CO2 needs of a greenhouse or greenhouse area.
The power of sunlight (project number E24004)
The development of innovative technologies that specifically alter the sunlight spectrum and implement and test these in greenhouse materials such as screens, coatings and greenhouse cover materials. That is the aim of this project. In time, new screens, coatings and greenhouse cover materials have been developed that can be used by practitioners to save energy.
MTO for greenhouse horticulture (project number E24005)
The project aims to generate generic knowledge on the effects of MTO (Medium Temperature Storage) on groundwater quality and soil functions. This knowledge is needed to overcome bottlenecks in the assessment of permit applications and monitoring. In addition, the aim is to develop management strategies to increase energy efficiency and mitigate negative effects on the living environment by limiting heat losses, for instance through adjustments to the injection and extraction cycles and techniques such as Power2Heat. A contribution was requested from the Top Sector Water for this project.
The following nine projects were funded by the Ministry of LVVN under Kas also Energiebron (Greenhouse as a Source of Energy):
Capture CO2 and temporary storage in a CO2 battery (project number 24021).
The aim of this project is to determine the quality and economic feasibility of CO2 from shipping after storage in a CO2 battery for an entire crop. This is to promote the utilization of this new CO2 source.
Fencing with low-e always a good idea? (project number 24022)
This project aims to quantify the energy savings of transparent screen cloths with high reflection for heat radiation so that there is as little radiation as possible (low emission) and cloths can also be closed as much as possible during the day for maximum energy savings with minimal light loss.
Low-ε glass and (LED) lighting. Phase 2: cultivation (project number 24023)
This project aims to reduce energy consumption for heating in LED-lit (ornamental) cultivation. To determine the performance of Low-ε glass for an ornamental crop in combination with lighting, dehumidification and other HNT measures.
Grip on even more light part 2 (project number 24024)
This project wants to determine the damage limits for light damage at a hortiscatter of 90% compared to ~45% so that in the future the light demand of light-sensitive crops can be filled to a greater extent with natural sunlight. This is done with a new system: slats at the top of the greenhouse.
Fossil-free winter cultivation chrysanthemum (project number 24025)
The objective of this project is to demonstrate a completely fossil-free chrysanthemum crop without WKO, by means of the dynamic use of LED lighting with high maximum lighting intensity in combination with an adequate strategy of insulation, dehumidification, heat harvesting and short-term (24-hour) heat buffering.
Acceleration towards energy-efficient full-LED cultivation of Lily (project number 24026)
The aim of the project is to develop and share knowledge on issues concerning energy-efficient cultivation strategies and nutrient uptake in lilies when grown under full LED. To be able to quickly put knowledge from the research into practice, a greenhouse trial at the Improvement Centre is running in parallel with the crops that are being grown by growers.
Plant temperature: the grower in control (project number 24027)
The aim of this project is knowledge about whether researchers can get a grip on the right plant temperature to grow properly when making technical adjustments to the production system. By measuring the right temperatures and then also controlling them, the entrepreneur is better able to make the most of new innovations or make the decision to invest in a new technique sooner.
Phalaenopsis towards fossil-free in warm propagation phase II (project number 24028)
This project aims to achieve sustainable and eventually fossil-free Phalaenopsis cultivation with low energy use for lighting and minimal heat demand. There are recent and ongoing studies working towards the realization of this. This proposal fits within the roadmap to achieve this.
Tocht no chance, energy in balance (project number 24029)
The aim of the project is to quantify leakage ventilation through the greenhouse structure, to analyze the effect leakage ventilation has on energy and CO2 consumption and finally to indicate potential energy savings by minimizing leakage.
