1. 1. The global energy system through a prism of change : The oil & gas industry and the case of the Arctic

   Författare :Maria Morgunova; Vladimir Kutcherov; Pär Blomkvist; Stefan Andreasson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; global energy system; energy industry; oil gas industry; Arctic offshore; change; transformation; sustainable energy transition; industrial dynamics; multi-level perspective; development blocks; globalt energisystem; energibranschen; olje- och gasindustrin; Arctic offshore; förändring; omvandling; hållbar energiövergång; industriell dynamik; flernivå perspektiv; utvecklingsblock; Industriell ekonomi och organisation; Industrial Economics and Management;

   Sammanfattning : The energy industry as a whole and the oil & gas industry in particular is experiencing changes under the influence of a variety of trends and the changing needs of society. Current social, economic, environmental and climate challenges are raising sharp questions for the established principles of energy production and consumption, increasingly arguing for sustainable trajectories in the development of the global energy system.

3. 2. Electrification in Process Industry - The Role of Process Integration and Future Energy Market Conditions

   Författare :Holger Wiertzema; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrification; bottom-up assessment; energy-intensive process industries; oxo synthesis; oil refining; energy market scenarios; techno-economic assessment; chemical industry;

   Sammanfattning : Electrification of industrial processes is a frequently discussed strategy to reduce greenhouse gas emissions from energy-intensive process industries and is highlighted in many roadmap studies. Electricity is a versatile energy carrier that enables a broad variety of options in which existing process unit operations are replaced with electricity-driven alternatives. LÄS MER

4. 3. Life Cycle Assessment of Present and Future Marine Fuels

   Författare :Selma Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   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. 4. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification

   Författare :Daniella Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; post-combustion CO2 capture. CO2 capture and storage CCS ; GHG emissions; oil refining industry; CO2 emissions; Fischer-Tropsch FT ; biomass gasification; energy market scenarios;

   Sammanfattning : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. LÄS MER

7. 5. Optical remote sensing of industrial gas emission fluxes

   Författare :John Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical remote sensing; DOAS; gas emission; absorption spectroscopy; VOC; flux measurement; solar occultation; FTIR; formaldehyde;

   Sammanfattning : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have repeatedly shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.
