Abstract [en]

This report is a result of a thesis work within ALSTOM Power Sweden and intended as guidance for life cycle assessments (LCA) and environmental product declarations (EPD) of power generating products. The method is based on the development of environmental product declarations for three selected company core products, one power plant and two gas turbines. ALSTOM Power is one of six sectors within ALSTOM and a world leader in the supply of power generation equipment and services. The product line of ALSTOM Power Sweden (Finspong) ranges from components to turnkey plants for power and heat generation. Finspong is the global Lead Centre for gas turbines 15-50 MW and steam turbines <100 mw. the report includes recommendations on scope definition and method of inventory, impact assessment and interpretation. in order to avoid unnecessary use of time end resources it is important that the lca process should be as iterative as possible. the impact assessment should not include more elements than selection of impact categories, classification and characterisation if the results are going to be used in an epd. the emphasis of the inventory should be on the operation. in the life cycle assessments of the selected products the contributions from the manufacturing phase to the impact categories, over-all resource consumption and generation of waste were almost negligible. since data concerning the operation are relatively easy to obtain based on design parameters and made assumptions, additional lca to compare different applications, load-profiles, ambient operating parameters or fuel types, would not require much time and resources. results should preferably be reported both including and excluding fuel- handling processes. this solution reflects the environmental impact of the entire product system at the same time as it enables the customer to combine the results with environmental information from a fuel supplier. although the objective of the study not primarily is to obtain a certified epd, compliance with the requirements stated in the international standards iso 14040-43, iso 14020 and iso 14025 is recommended.
