Reduced CO2 mitigation costs by multi-functional biomass production

På svenska

Author

Summary, in English

The CO2 mitigation cost when biomass replaces fossil fuels depends on several factors, such as the type of fossil fuel replaced, the energy systems involved, induced changes in the biospheric carbon stock, and the intensity and efficiency of the biomass production. Irrigation of energy crops, using nutrient rich municipal wastewater and drainage water, can lead to substantially improved productivity while at the same time addressing pollution of ground water and eutrophication. The cost of the biomass produced in such multifunctional biomass production systems will also be significantly reduced. Previous studies show that the CO2 mitigation cost when fossil fuels are replaced by biomass is often most sensitive to changes in fuel costs. Thus, a significant reduction in the biomass production cost will simultaneously lead to a substantial reduction in the CO2 mitigation cost. This paper shows that the CO2 mitigation cost could be significantly reduced, or even negative, when biomass from willow vegetation systems irrigated by nutrient-rich wastewater is utilised for replacing natural gas for heat and power production.
