21. Investigation of Emission Characteristics for Diluted Flames and Renewable Fuels in Gas Turbine Combustors
Sammanfattning : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. LÄS MER
22. Modelling Life Cycle Cost for Indoor Climate Systems
Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. LÄS MER
23. DC Distributed Power Systems - Analysis, Design and Control for a Renewable Energy System
Sammanfattning : Renewable energy systems are likely to become wide spread in the future due to environmental demands. As a consequence of the dispersed nature of renewable energy systems, this implies that there will be a distributed generation of electric power. LÄS MER
24. Comparative Assessment of Fuel-Based Systems for Space Heating
Sammanfattning : Replacing fossil fuels by biofuels and increasing energy efficiency are often considered to be options for reducing the net emission of greenhouse gases. This thesis presents the results of analyses of energy efficiency, emission and cost of whole energy system chains, from the natural resource to the end user when heating detached houses in a Swedish context.

25. Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications
Sammanfattning : Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. LÄS MER
