| dc.description.abstract | This study aims to perform hybrid life cycle assessment of potential environmental implications due to expansion of electricity transmission grid which would allow to including intermittent energy sources.
Existing studies in this field of research employ process-based life cycle assessment techniques which inevitably suffer from truncation errors. This can potentially cause underestimation of significant share of impacts. Hybrid tiered analysis performed for the case project seeks to redress this gap.
The results showed that total impacts generated in physical (process-LCA)
sub-system are nearly four times higher than that of monetary one (Input-Output). The share of monetary sub-system related impacts are lower than expected, but are significant nevertheless.
The structure of this report is as follows. In chapter 1 introduction into the topic is given, followed by literature review, case identification and methods description in next chapter. Chapter 3 covers life cycle inventories and cost data adapted to perform life cycle impact assessment. In the following chapter, the results of such assessment are reported, while chapter 5 provides discussion on obtained results. Finally, chapter 6 concludes this study and lists potential improvements for next work. | |
