BENSIM (BioENergy SImulation Model) and BENOPT (BioENergy OPTimisation model) have been developed in order to model the competition between different bioenergy technology options. BENSIM/BENOPT exists in two main variants: (1) a myopic, recursive simulation model that looks for the most cost-effective technology mix under certain conditions including technological learning (BENSIM), and (2) a perfect foresight optimization model for optimal allocation of dispatchable renewable energy carriers across different sectors and goal functions (BENOPT).
BENOPT is a model for optimizing the use of dispatchable renewable energy carriers. Two goal functions can be used or combined: greenhouse gas (GHG) abatement or cost minimisation for fulfilling set energetic or GHG targets. In combination, pareto analyses can be performed.
BENOPT contains sectors for transport (road passenger, road goods, shipping and aviation), power and heat (industry, household and commercial). Work is planned on integrating important chemical products. The model functions on a yearly resolution (with the exception of surplus power usage, which can be broken down to an hourly resolution) and is not spatially explicit. Detailed input-output, capex and opex data are integrated for feedstocks, conversion and supply (vehicle data is planned), which allows detailed cost analyses and combined with relevant emission factors also GHG analyses.
Stand-alone versions focusing on chemical products (Frazer Musonda) as well as on the heat sector (Matthias Jordan) have been developed.
The models are also used to investigate the sensitivity of the developments by means of various methods (Monte Carlo, SOBOL), on which a large number of parameters have an influence, especially in the complex area of biomass use.
BENSIM/BENOPT was/is used in the following projects and in each case adapted and further developed:BioNET (optimisation: negative emission technologies)
Meilensteine 2030 (simulation: power, heat, fuels)
BEPASO (optimisation: power, heat, fuels, chemicals)
BioPlanW (optimisation: heat)
BKSQuote (optimisation: fuels)
TATBio (optimisation: power, heat, fuels)
BEniVer (optimisation: biofuels and electrofuels)
AGRI-TRANSFORM (optimisation: all sectors, including food)
SoBio (optimisation: power, heat, fuels)
