REMIND models three types of bioenergy feedstocks:
- First-generation biomass produced from sugar, starch, and oilseeds (typically small in quantity, based on an exogenous scenario);
- Ligno-cellulosic residues from agriculture and forest; and
- 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 draws on an emulation of the land-use model MAgPIE (Model of Agricultural Production and its Impact on the Environment) (Lotze-Campen et al. 2008; Popp et al. 2010; Lotze-Campen et al. 2010). The emulator describes supply costs and total agricultural emissions as a function of bioenergy demand, as described in detail in Klein et al. (2014). 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 bases on low-cost bioenergy supply options. Their potential is assumed to increase from 20 EJ/yr in 2005 to 70 EJ/yr in 2100 (Chum et al. 2011), based on Haberl et al. (2010).
In REMIND, 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 rise (Sims et al. 2010). We also assume that first generation modern biofuels are phased-out, reflecting their high costs and to account for concerns about land-use impacts, co-emissions, and competition with food production from first-generation biofuels (Fargione et al. 2008; Searchinger et al. 2008). As a concequence, the main sources of bioenergy in REMIND sceanrios are second-generation purpose-grown biomass and from ligno-cellulosic agricultural and forestry residues.
To further reflect concerns about the sustainability of large-scale deployment of lingo-cellulosic bioenergy, REMIND 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.
