6. Promotion of sustainable renovation in the built environment : An early stage techno-economic approach
Sammanfattning : According to the Swedish Government's set targets for energy use and environmental quality imposed by the European Union, the total energy per heated unit area in residential and commercial buildings will have to be decreased by 20% in 2020 and 50% by 2050 in relation to the annual consumption of 1995. The building sector should additionally be completely independent of fossil fuels for energy usage, with the increasing sector of renewable energy continuously growing until 2020. LÄS MER
7. Evolution of Techno-Economic Systems - An Investigation of the History of Mobile Communications
Sammanfattning : The purpose of this thesis is to contribute to the understanding of how techno-economic systems emerge and evolve and how such processes can be analyzed. To these ends, the history of mobile communications is investigated, seen as a complex techno-economic system with two rapidly evolving and interacting subsystems - mobile telephony and mobile data communications - which are described, dissected and compared in case studies.

8. Integrated sewage sludge treatment scenarios – techno-economic analysis on energy and phosphorus recovery
Sammanfattning : Sewage sludge is a by-product of wastewater treatment that simultaneously gathers contaminants, valuable organic matter, and nutrients. The treatment of the increasing amount of sewage sludge is important from both pollution prevention and resource recovery perspectives as i) large shares of mineral phosphorus, listed as a critical raw material, terminate in the sewage sludge, and ii) energy recovery from sewage sludge can cover the energy-intensive demand of the treatment process.

9. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance
Sammanfattning : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

10. A Techno-Economic Framework for the Analysis of Concentrating Solar Power Plants with Storage
Sammanfattning : Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. LÄS MER
