Abstract
Various crops can be considered as potential bioenergy and biofuel production feedstocks. The selection of the crops to be cultivated for that purpose is based on several factors. For an objective comparison between different crops, a common framework is required to assess their economic or energetic performance. In this paper, a computational tool for the energy cost evaluation of multiple-crop production systems is presented. All the in-field and transport operations are considered, providing a detailed analysis of the energy requirements of the components that contribute to the overall energy consumption. A demonstration scenario is also described. The scenario is based on three selected energy crops, namely Miscanthus, Arundo donax and Switchgrass. The tool can be used as a decision support system for the evaluation of different agronomical practices (such as fertilization and agrochemicals application), machinery systems, and management practices that can be applied in each one of the individual crops within the production system.
Highlights
Various crops can be considered as potential bioenergy and biofuel production feedstocks.The selection of the crops to be cultivated for that purpose is based on several factors, including plant requirements, farmers’ preferences, geographical dispersion of the cultivated area, agricultural practices, and available equipment
An evaluation of the economic or energy benefits between potential crops to be cultivated in an area is required; this applies in the case of strategic planning in terms of bioenergy crop production within a specific area
All the in-field and transport operations are taken into account, providing a detailed analysis of the energy requirements of the components that contribute to providing a detailed analysis of the energy requirements of the components that contribute the total energy consumption
Summary
Various crops can be considered as potential bioenergy and biofuel production feedstocks. Tool is based on anfacilities), in-depth work breakdown accounting crop protection used may lead to high variations in the energy input requirements for each in-field and transport operations presenting the Miscanthus x giganteus production. The task durations for the machinery activities are usually based on tool provides detailed analysis on the energy requirements of the components that contribute to the average norms and do not provide results for the design or evaluation processes of a specific energy production input. The structure of the present work is as follows: initially, a brief presentation of the tool in terms This is of followed the results section, where a comparison between various energy costs the mainbyinput parameters and functionalities is provided.
