Abstract

In the near future the greenhouse horticultural sector wants to produce free of fossil energy. To be able to worktowards this purpose, it is important that the possible roads are mapped out on time. In this report, these roadsare presented in a qualitative sense. In fact, there are 2 types of primary energy sources, namely green electricityand residual heat/geothermal energy, each requiring other technical solutions depending on the type of cultivation(divided in this report into cold extensive crops, not, -moderate and -heavily artificial lighted crops).If greenhouses are heated by electricity, then the heat pump in combination with heat-cold storage, is thebest solution both energetically and economically wise. When using residual heat or geothermal energy, theheat pump can play a role, but less prominent than in an all-electric energy infrastructure. In all cases a gooddehumidification system is important. Energy systems in a fossil-free infrastructure are characterized by highfixed costs and low variable costs. These high fixed costs can be reduced by lowering the capacities using betterisolation and low temperature heating systems.This report has set the spot on the horizon for a CO2 neutral horticulture. How we get there depends on thepreconditions that will change on the way. This calls for energetic and economic indicators for different crops andoptions for the primary energy source that take into account those changing preconditions
