1. Design and analysis of solid oxide electrolysis-based systems for synthetic liquid fuels production
Sammanfattning : During the past decades, considerable attention has been dedicated to renewable energy systems. This is due to the increased awareness regarding greenhouse gas emissions as well as limits of the future availability and reliability of conventional energy and power systems. LÄS MER
2. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry
Sammanfattning : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production: the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

3. A systematic approach for major renovation of residential buildings
Sammanfattning : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. LÄS MER
4. Life cycle primary energy use and carbon emission of residential buildings
Sammanfattning : In this thesis, the primary energy use and carbon emissions of residential buildings are studied using a system analysis methodology with a life cycle perspective. The analysis includes production, operation, retrofitting and end-of-life phases and encompasses the entire natural resource chain. LÄS MER
5. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances
Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER
