This report provides an inventory of potential and costs for waste heat utilization in the Netherlands for low temperature application in households, services and greenhouse horticulture towards 2020. Despite large amounts of available waste heat, the amount that makes sense to be used in heat distribution for households, offices and greenhouses is relatively limited: an estimated 20 to 45 PJ. Deployment of this waste heat would result in an estimated 10-25 PJ saving of primary energy. The main cause for this apparent discrepancy between a large supply of waste heat and limited possibilities for using it, is the poor match between supply and demand: heat is often not available at the right temperature level, the right time and the right place. Moreover, alternatives for deployment of waste heat on the supply side and alternative heat sources on the demand side, may be more attractive in terms of savings, emission reductions and costs. The quantitative results that are shown represent indications of effects on energy use, emissions and costs, but do not reflect specific cases.
