26. Efficient energy use in different applications
Sammanfattning : There is a steadily growing awareness for environmental issues caused by the increased energy use, mainly in the industrial world. The use of fossil fuels has reached the point where it can not be looked at as an endless source, the resources are decreasing at a pace where alternative energy sources will be a necessity for this and future generations.

27. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries
Sammanfattning : This thesis investigates the operational parameters of fossil-based power generation and industrial processes in future energy systems that have stringent constraints on CO2 emissions, and, consequently, large shares of renewable energy. CO2 capture and storage, which is the focus of this work, is required for power and industrial processes that emit CO2. LÄS MER
28. Modulation, efficiency and lifetime of two-level and multilevel converters for a hydropower application
Sammanfattning : Along with the integration of the renewable energy in the electrical grid, the pumped-storage hydropower has gained more and more attention due to its fast response and energy storage ability. To have a higher overall efficiency and more flexibility of the system, variable speed is preferred in the operation of the pumped-storage hydropower applications. LÄS MER
29. Decarbonization in Carbon-Intensive Industries - An Assessment Framework for Enhanced Early-Stage Identification of Optimal Decarbonization Pathways
Sammanfattning : Carbon-intensive industries currently account for a quarter of global annual CO2 emissions. Achieving mandated climate targets necessitates the rapid implementation of decarbonization technologies in these industries. Such deployments typically involve substantial upfront investments amidst technical, economic, and policy uncertainties. LÄS MER
30. Dampening variation in the European Wind Energy System
Sammanfattning : In a future European electricity system, wind power and other variable renewables may constitute a large share of electricity production. This prospect calls for measures to manage the inherent variability of wind power, such as demand-side management, storage, and flexibility of other generation. LÄS MER
