In this study an assessment is made of the future demand of fertilizers from bioenergy crop production. A representative sample of various assessments on the contribution of bioenergy is derived from literature. The projections are translated into fertilizer demand, assuming that all bioenergy is produced from dedicated woody bioenergy crops. The amount of nutrients in the harvested biomass is used as a proxy for the fertilizer demand. Results indicate that the global demand for fertilizer for bioenergy crop production is limited to 1% to 8% in 2015 and 2% to 16% in 2030 of the total global demand for fertilizers for agriculture (excluding bioenergy crop production), equal to 1 Mt, 12 Mt, 4 Mt and 26 Mt, respectively (sum of N, P2O5 and K2O). Particularly during the second quarter of the 21st century the production of bioenergy crops could increase rapidly, which could result in a fertilizer demand (sum of N, P2O5 and K2O) of 16 Mt to 63 Mt in 2050. The technical potential for bioenergy crop production are however much larger, comparable to a technical fertilizer demand in 2050 of 108 Mt to 640 Mt. Login to post comments
