BeWhere Description

The BeWhere model is an optimization model that determines the optimal size and location of bio-energy production plants based on the minimization of the cost of the complete supply chain.

Model Structure

The BeWhere model is a mixed integer linear program, techno-economic model, geographically explicit on a half a degree grid, and it is static.

It minimizes the objective function defined as:

(Total cost) = (Production cost) + (Total emissions) * (Carbon cost)

where (Production cost) and (Total emissions) are the production cost and the total emissions of the whole supply chain respectively.

Based on the economy of scale, the model determines the optimal numbers, properties (capacity, technology) and the localization of bio-energy plants for the welfare of the region studied.

Feedstock

A large variety of feedstock can be considered in the model. Nevertheless, the focus is on second generation biofuel, and therefore, crop residuals, forestry waste, lignocellulosic industrial waste are included in the model.

Transport

A transport network is included in the model. Transportation by the combination of truck, train and boat is possible regarding the infrastructure of the region.

Process

The selected plant(s) can be a new biofuel production plant or combined heat and power plant. Different technologies such as gasification or hydrolysis and fermentation can be selected.

Demand

The transport fuel demand has to be met by the new biofuel production plants, biofuel imports or/and additional fossil fuel in regards with prices and emissions.
