Systems

This research addresses the feasibility and resource efficiency of different types of biogas solutions. For example, Multi-Criteria Analysis methods have been established to support strategic decision making regarding biogas feedstock, to clarify strengths, weaknesses and opportunities for different options. Further on, Life-Cycle Assessment (LCA) and Life-Cycle Costing (LCC) are used for studies of the economic and environmental performance of existing and future biogas systems. Identification of critical factors and uncertainty handling are important parts of these types of systems analyses, and probability distributions for different outcomes are important results.

Strategic multi-criteria assessment of biogas solutions

Strategic multi-criteria analysis of biogas solutions – from assessment of substrate to other perspectives

The Swedish biogas potential is great but far from implemented, where an important explanation is that existing producers face several types of challenges and the investment landscape is uncertain. Considering future development within the biogas sector it is important to gather and structure relevant information about different existing and potential biogas solutions, for example, in different contexts with varying purposes; involving a variety of feedstock and technology.

The main aim of this project is to increase the knowledge about the feasibility and resource efficiency of different types of biogas solutions and to contribute to method development regarding how to assess feasibility and resource efficiency. Multi-Criteria Analysis (MCA) methods will be used for strategic, broad and systematic assessments of biogas solutions that are of interest for the partners and members of BRC.

By developing suitable methods for MCA and applying them, strengths and weaknesses of different character become clearer in combination with the certainty of each result. It is also possible to identify patterns, bottlenecks, risks, opportunities, etc. A main idea is to collect relevant information and structure it to facilitate strategic overviews, communication and informed decision making. This is relevant for development within the biogas and biofertilizer industry, to define and prioritize among essential research projects, regarding policy, etc.

Quantitative system analyses for improved resource-efficiency of different biogas solutions – critical factors and uncertainty handling

Biogas is seen by many as one of the better climate strategies in the work on fossil free energy systems. In addition, biogas production has many links to higher resource efficiency in society: eco-cycles of nutrients, lower utilization of fertilizer and resource utilization in local and regional energy systems. Despite this, many plants struggle with their economic profitability and mention the shortage of long-term political rules of the game which is a large risk factor.

In this respect, quantifications of performance for different types of biogas solutions can help to streamline individual plants by demonstrating critical factors. In addition, these studies can highlight the role of biogas in society and send important signs to decision-makers. The aim of this project is to conduct quantitative studies on resource-efficiency for different biogas solutions, and to quantify the social effects which implementation of these solutions can generate. The project studies resource efficiency based on four focus areas: environment, economy, energy and nutrients.
