Anwendung energetischer und nicht-energetischer Ressourcen in Energiesystemen: vergleichende Bewertung - Teil 1: Methodik und exemplarisch ausgewählte Lebenswege

Goal and Scope. Which impact does the use of non-energetic abiotic resources (ores, minerals, etc.) have in life cycles of energy systems based on biogenic and fossil fuels? Is this kind of resource use less or more environmentally harmful than the utilisation of energetic abiotic resources (mineral oil, natural gas, etc.) in the same life cycles? This paper aims at answering these questions. In Part 1, a methodology is presented and applied to the life cycles of selected energy systems. Part 2 presents and discusses the results. Method. This study looks at the complete life cycles of selected energy systems. The methodology used bases on the state-of-the-art of life cycle assessment (LCA) methodology. For the assessment of energetic abiotic resource use, a widely recognised method can be used. For the assessment of non-energetic abiotic resource use, no overall recognised methodological approach exists. That is why for this aspect two different methods are exemplarily applied and compared with each other. Results and Conclusion. Results will be presented and discussed in Part 2. Recommendation and Perspective. Recommendation and conclusions will be derived from study results in Part 2.
