Energy biomass is produced from the following surfaces:


* 1st generation biofuels: agricultural area, grassland
Primary biomass resources for energy uses are classified in 3 categories for all POLES 57 countries / regions:
* other uses: forest area (for forest residues), grassland (for short rotation crops)
* energy crops (in agricultural area, grassland)
* short rotation crops (cellulosic)
* forest residues (cellulosic)


Yields evolve over time, based on historical evolutions.
Energy crops are dedicated to 1st generation biofuels, the 2 other categories are used in all other energy uses (a further split of biomass feedstocks has been implemented for Europe using information from the model GREEN-X). POLES uses by default a simplified modeling of land use to estimate the potential of these resources: land available, yields (evolve over time, based on historical evolutions), share of harvest/land that can be allocated to energy uses.

    Primary biomass resources for energy uses are classified in 3 categories for all POLES 57 countries / regions:

    • energy crops (in agricultural area, grassland)
    • short rotation crops (cellulosic)
    • forest residues (cellulosic)

    Energy crops are dedicated to 1st generation biofuels, the 2 other categories are used in all other energy uses (a further split of biomass feedstocks has been implemented for Europe using information from the model GREEN-X). POLES uses by default a simplified modeling of land use to estimate the potential of these resources: land available, yields (evolve over time, based on historical evolutions), share of harvest/land that can be allocated to energy uses.

    Biomass resource use in POLES

    POLES also uses in a standard way exogenous estimates of potentials: for instance a soft linkage with the model GLOBIOM/G4M has been implemented that goves potential estimates and cost curves for all World regions (with the model GREEN-X at EU level). Biomass supply cost curves are attached to the various biomass types and come from GREEN-X, GLOBIOM and other sources.

    The conversion into liquid biofuels distinguishes first generation (agricultural energy crops) and second generation (cellulosic).
