Sammanfattning
This thesis examines the relationship between industry structures and low-carbon energy transition
in the Scandinavian countries. The thesis is sorting out the most carbon intensive industries in Scandinavia
and then analyzing the energy mixes the industries use in order to operate. The selected
industries the thesis proceeds to analyze were the steel manufacturing industry the cement manufacturing
industry and the refining of petroleum products. In order to grasp the energy use and supply of
the chosen industries, different reference energy systems (RES) where established for the three different
countries, which was the main methodology for this thesis. The RES provides an overview of the
energy mixes of the energy supply and demand of the chosen industries. One of the main findings were
that most of the emissions in the steel and cement industry occur in the chemical processes, while the
largest source of emissions in the refining industry came from the combustion of natural and refinery
gas.
The next phase of the thesis provides results regarding new technologies for the industries that allows
them to operate without emitting any greenhouse gases (GHG). The thesis argues that the refining
industry will be converted into bio refining, making solely bio fuels. Regarding the steel industry it
was found that hydrogen could be used as an reducing agent instead of using cok which allowed them
to reach zero emissions. For the cement manufacturing industry a plasma technology in combination
with carbon capturing and storage would allow the industry to reach zeros emissions. Although this
technologies where found to be the most reasonable to utilize in the future, the cost is a huge increase
in demand for green electricity. This is shown in a RES diagram which illustrates the energy flows
in the energy systems for the studied countries and industries for 2050. The findings shows that the
demand for green electricity and bio mass will rapidly increase in 2050. Furthermore, the biggest
challenges lies within the expansion of wind power that will provide the new industry technologies
with green electricity. Another challenge for the future energy system is the supply of bio mass, which
will take the role of fossil fuels in 2050.
