1. Cost and financing of the sustainability transition of the Swedish road freight transport sector
Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.

2. Fossil Free or Not - That is the Question
Sammanfattning : This is an evaluation of Jämtland County’s ability to achieve its climate targets to reduce greenhouse gas (GHG) emissions with 10% annually, and to become fossil fuel free 2030. There is a risk that the target to become fossil fuel-free, relying primarily on outtake of forest biomass, contradicts with the target in the UN Paris Agreement to keep the global temperature increase below 1.

3. Non-geological hydrogen storage for fossil-free steelmaking
Sammanfattning : In the last half-century, global steel use has increased more than threefold and further growth is expected, particularly in developing economies. However, steelmaking is currently responsible for 7% of the global net carbon dioxide (CO2) emissions, and any substantial further optimization of existing processes that utilize fossil fuels for iron ore reduction is infeasible.

4. Life Cycle Assessment of Present and Future Marine Fuels
Sammanfattning : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

5. 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.
