Life cycle assessment of an offshore grid interconnecting wind farms and customers across the North Sea
Arvesen, Anders; Nes, Rasmus Nikolai; Huertas-Hernando, Daniel; Hertwich, Edgar G. (Journal article; Peer reviewed, 2014)Purpose: This study aims to contribute to an improved understanding of the environmental implications of offshore power grid and wind power development pathways. To achieve this aim, we present two assessments. First, we ... -

Life Cycle Assessment of Desalinated Water for Enhanced Oil Recovery
Kvadsheim, Mari Hellvik (Master thesis, 2013)Currently, fossil fuels supply 85% of the world?s energy demand. Nevertheless, we consume more than we are able to produce from new discoveries of fossil resources. As energy demand is predicted to grow rapidly over the ... -
Life cycle assessment of electric power generation by wind turbines containing rare earth magnets
Venås, Christoffer (Master thesis, 2015)Direct-drive permanent magnet generator (DD-PMG) wind turbines are becoming a larger part of the growing offshore wind turbine market. The strong permanent magnets used, the NdFeB magnets, contains neodymium metal. The ... -
Life Cycle Assessment of Electricity Transmission and Distribution
Hauan, Ingrid Bjerke (Master thesis, 2014)As the integration of renewable electricity production progresses and the energy consumption pattern evolves, the transportation of energy is essential for securing sufficient supply while meeting political targets. Power ... -
Life Cycle Assessment of Offshore Wind Electricity Generation in Scandinavia
Tveten, Åsa Grytli (Master thesis, 2009)In this study a Multi Regional Input Output model has been developed for the base year 2000, and thereafter extended and hybridized to enable a study of offshore wind power generation in Scandinavia. Foremost the per-unit ... -
Life cycle assessment of transport of electricity via different voltage levels: A case study for Nord-Trøndelag county in Norway
Arvesen, Anders; Hauan, Ingrid Bjerke; Bolsøy, Bernhard Mikal; Hertwich, Edgar G. (Journal article; Peer reviewed, 2015)Electricity transmission and distribution (T&D) plays a vital role in society by connecting electricity producers and consumers. We present a life cycle assessment case study of electricity delivery to consumers in ... -
Life-cycle assessment of international vacation packages
Veselkova, Anna (Master thesis, 2014)This thesis aims to perform a Life Cycle Assessment in order to explore environmental impacts associated with a vacation package. It identified the phases of the holiday that generated the largest impact, the most significant ... -
More caution is needed when using life cycle assessment to determine energy return on investment (EROI)
Arvesen, Anders; Hertwich, Edgar G. (Journal article; Peer reviewed, 2015)Cumulative energy demand (CED) estimates from life cycle assessments (LCAs) are increasingly used to determine energy return on investment (EROI), but the difference in indicators can lead to a misclassification of energy ... -
The Importance of Ships and Spare Parts in LCAs of Offshore Wind Power
Arvesen, Anders; Birkeland, Christine; Hertwich, Edgar G. (Journal article; Peer reviewed, 2013)We develop and assess life cycle inventories of a conceptual offshore wind farm using a hybrid life cycle assessment (LCA) methodology. Special emphasis is placed on aspects of installation, operation, and maintenance, as ... -
Understanding the Environmental Implications of Energy Transitions. A Case Study for Wind Power
Arvesen, Anders (Doktoravhandlinger ved NTNU, 1503-8181; 2013:8, Doctoral thesis, 2013)A fundamental change in the ways in which we provide energy to run our economies, an energy transition, is needed to mitigate climate change. Wind power is an important part of future global energy supply in most energy ...
