Resource consumption of energy technologies in different LCA-databases - Analysis of uncertainties for the sectors electricity, heat, mobility and an exemplary assessment of a chosen energy technology

Kurzfassung

The thesis analysis existing inventories in ecoinvent and GaBi and shows that the diversity of technologies for the sectors electricity, heat and mobility in energy scenarios or energy system models (ESM) are not sufficiently covered. Furthermore, many insights and detailed information concerning the structure and possible uncertainties in LCA databases are gathered and highlighted. An exemplary upscaling of a wind turbine shows that high material requirements are induced due to a massive increase of the tower top weights which is likely to force a technology switch or material substitution in the future.
