Forestry biomass reference energy system within a National TIMES model

  1. 1. Flows of Woody Biomass in TIMES-Sweden Anna Krook Riekkola and Erik Sandberg Luleå University of Technology (LTU), Sweden 1
  2. 2. 2 MOTIVATION and AIM Motivation and background: Biomass may be an important key to get to net zero GHG emissions. - Replace fossil fuels for vehicles, space heading, industry and , electricity&DH production as well as - Replace energy-intensive materials (such as cement in buildings) and oil-products. The question is where and how biomass reduces CO2 to the lowest cost? E.g. assessed by a national TIMES model. Difficult to get the numbers correct when biomass is not one unique commodity with a straight flow throughout the reference energy system. 2 Aim: To create a ‘Reference Energy System’ of biomass flows
  3. 3. 4 Flows of Woody Biomass in TIMES-Sweden A biomass reference energy system Conditions  Biomass is not a uniform commodity.  Competition of biomass also between biomass as material and biomass as energy source.  The biomass potential from forest is driven by the demand for ‘timber’.  If biomass bi-products is withdrawn from an industry, additional energy sources may be needed.  Coherence between results and statistics. Modell structure should capture  Different fractions based on source and on possibility for use.  Primary commodity should be able to ‘deliver’ both material and energy commodities.  Link potential of forestry biomass to use of ‘round wood’/’timber’.  Bi-product: capture the difference IF the bi-product is ’exported’ from the industry OR used within the industry.  In line with statistics and avoid double counting -> Naming
