Hybrid Life Cycle Assessment of Large Scale Hydrogen Production Facilities
(Working Papers from Industrial Ecology Programmme (IndEcol), 1504-3681; 2004:3, Research report, 2004)An environmental assessment of three designs for a large-scale hydrogen production facility is performed using a Hybrid Life Cycle Assesment approach. The operational adaption of the hybrid framework for this case is shown ... -
Hybrid life cycle assessment of steel production with carbon capture and storage
(Master thesis, 2013)Among several Green house gases, CO2 is a main contributor and accounts for about 60% of the greenhouse effect because of its huge emission amount. The iron and steel sector has showed one of the largest energy intensity ... -
Hybrid Life Cycle Assessment of Wood-based Biofuel Production and Consumption Scenarios in Norway
(Master thesis, 2008)An increasingly urgent need to develop alternatives to fossil fuels in road trans- portation stems from both the need to combat climate change and the need to prepare for a transition beyond peak oil. Biofuels can be part ... -
