21. Från el till värme : en diskursanalytisk policystudie av energiomställning på statlig, kommunal och hushållsnivå
Sammanfattning : The aim of this thesis is to analyse how space heating for single-family houses, and energy system conversion has been constructed and discussed at national, municipal and household levels. Political documents have been studied, and interviews have been carried out with politicians, civil servants and householders in the municipality of Falun. LÄS MER
22. Production planning of CHP plants integrated with bioethanol production and local renewables
Sammanfattning : Production planning of an energy system is dependent on parameters such as energy demand and energy conversion technologies, which are influential in making decisions on operation strategy and optimal performance of the system. In accordance with the European Union energy policy, the share of renewable resources in the energy supply is growing. LÄS MER
23. Biohybrid Polymer Electrodes for Renewable Energy Storage
Sammanfattning : Daily and seasonally fluctuating energy supply and demand requires adequate energy storage solutions. In recent years electrochemical supercapacitors have attracted considerable attention due to their ability to both store and deliver electrical energy efficiently. LÄS MER
24. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator
Sammanfattning : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. LÄS MER
