REMIND-MAgPIE models three types of bioenergy feedstocks:

  1. First-generation biomass produced from sugar, starch, and oilseeds (typically small in quantity, based on an exogenous scenario);
  2. Ligno-cellulosic residues from agriculture and forest; and
  3. Second-generation purpose-grown biomass from specialized ligno-cellulosic grassy and woody bioenergy crops, such as miscanthus, poplar, and eucalyptus.

To represent supply of purpose-grown bioenergy from the land-use sector, REMIND-MAgPIE can either be run in standalone mode or soft-coupled to the land-use model MAgPIE (Model of Agricultural Production and its Impact on the Environment) [1]; [2]; [3], see also Section “Land Use” . In standalone mode, REMIND-MAgPIE draws on an emulator of MAgPIE, which describes bioenergy supply costs and total agricultural emissions as a function of bioenergy demand, as described in detail in Klein [4]. The supply curves capture the time, scale and region dependent change of bioenergy production costs, as well as path dependencies resulting from past land conversions and induced technological changes in the land-use sector, as represented in MAgPIE. Ligno-cellulosic agricultural and forest residues are based on low-cost bioenergy supply options. Their potential is assumed to increase from 20 EJ/yr in 2005 to 70 EJ/yr in 2100 [5], based on Haberl [6].

In REMIND-MAgPIE, we assume that the use of traditional biomass (supplied by residues) is phased out, as modern and less harmful fuels are increasingly used with rising incomes [7]. We also assume that first generation modern biofuels are phased out, reflecting their high costs and accounting for concerns about land-use impacts, co-emissions, and competition with food production from first-generation biofuels [8]; [9]. As a consequence, the main sources of bioenergy in REMIND-MAgPIE scenarios are second-generation purpose-grown biomass and ligno-cellulosic agricultural and forestry residues.

To further reflect concerns about the sustainability of large-scale deployment of lingo-cellulosic bioenergy, REMIND-MAgPIE assumes an ad valorem tax on bioenergy. The tax increases linearly from 0 to 100% between 2030 and 2100 and is applied to the bioenergy price given by the emulator (see above). Based on the current public debate, we consider this tax to be a reflection of the potential institutional limitations on the widespread-use of bioenergy.
