11. Governance structures for promoting renewable energy sources
Sammanfattning : This study seeks to find answers to the question of how much competition is introduced by different types of regulation aimed at promoting electricity generated with renewable energies. For this purpose the partial equilibrium model is applied. LÄS MER
12. Winter Road Maintenance using Renewable Thermal Energy
Sammanfattning : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.

13. Power to gas : Bridging renewable electricity to the transport sector
Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER
14. Strategies for building polymers from renewable sources : Using prepolymers from steam treatment of wood and monomers from fermentation of agricultural products
Sammanfattning : A strategic research area today is development of polymericproducts made from renewable sources. The ways of utilizingrenewable sources studied in this thesis are using 1)prepolymers obtained by steam treatment of wood and 2) monomersobtainable by fermentation of agricultural products. LÄS MER
15. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers
Sammanfattning : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. LÄS MER
